The best indication for MSN is focal spasticity. We performed 298 MSN, 87 nerves on the upper limb, 211 nerves on the lower limb) in 68 patients. The initial causes were: stroke, cranial trauma, postoperative complications and multiple sclerosis. MSN procedures were performed on the median nerve (n = 40) for wrist and finger flexion;musculo-cutaneus nerve (n = 38) for elbow flexion;ulnaris nerve (n = 9) for cubital deviation of the hand;gastrocnemius nerve (n = 98) and soleus nerve (n = 49) for equinus foot, tibial posterior nerve (n = 45) for varus foot, and fascicles (or bundles) of the flexor digitorum for “claw” toes (n = 19). The main preoperative test to identify the responsible nerve was a neuromuscular block with local anesthesia (lidocaine or bupivacaine) injected into the site of the nerve connecting the spastic muscle. During surgery, the identified nerve was exposed and its epineurium opened. Nerve bundles were teased apart into individual rootlets and a number of rootlets cut were previously planned, according to the spasticity. Follow-up was performed for up to 10 years, with a mean period of 29 months. Results demonstrated a reduction of limb spasticity of 2 to 3 points: modified Ashworth scale (MAS). Pain and clonus were also diminished in the affected limb. In some cases, voluntary movement was once again possible. MSN is a useful alternative in those cases of focal spasticity where physiotherapy and nerve block with botulinum toxin or phenol no longer produce satisfactory results.展开更多

SCI models were established in SD rats. Five groups were set up randomly: normal control group, SCI 7-day(7 D) model group, SCI 14-day(14 D) model group, SCI-7 DrTMS group and SCI-14 DrTMS group(n=5 each). The rats in SCI rTMS groups were treated with 10 Hz rTMS from 8 th day and 15 th day after SCI respectively, once every day, 5 days every week, a total of 4 weeks. After the model establishment, motor recovery and spasticity alleviation were evaluated with BBB scale once a week till the end of treatment. Finally, different parts of tissues were dissected out for detection of variations of KCC2 protein using Western blotting and polymerase chain reaction(PCR) technique. The results showed that the BBS scores after treatment were significantly higher in SCI-7 DrTMS group than in SCI-14 DrTMS group(P<0.05). As compared with normal control groups, The KCC2 protein in SCI model groups was down-regulated after SCI, and the decrease was much more significant in SCI-14 D model group than in SCI-7 D group(P<0.05). As compared with SCI model groups, KCC2 protein in rTMS groups was up-regulated after the treatment(P<0.05). The up-regulation of KCC2 protein content and expression was more obvious in SCI-7 DrTMS group than in SCI-14 DrTMS group(P<0.05). It was concluded that 10 Hz rTMS can alleviate spasticity in rats with SCI, which might be attributed to the up-regulation of KCC2 protein. It was also suggested that the high-frequency rTMS treatment after SCI at early stage might achieve more satisfactory curative effectiveness.展开更多

The ASAS has been shown to be superior to other clinical tools for the assessment of spasticity in children with cerebral palsy but reliability has not been previously examined in adults. Method: Four muscle groups were rated on one occasion by four assessors using the ASAS in sixteen adults with unilateral hypertonia following acquired brain injury. Twelve participants returned one week later for reassessment by the same assessors. Results: Overall inter-rater reliability of the ASAS using a quadratic weighted Kappa was moderate (Kqw 0.58) with ranges from moderate to good (Kqw 0.42 - 0.70). Agreement between raters was greatest for soleus muscle and least for wrist flexors. Overall intra-rater reliability of each of the four raters was moderate to good (Kqw 0.48 - 0.79). Agreement within raters was greatest for soleus muscle and least for biceps muscle. Conclusions: The ASAS may represent an appropriate alternative to the clinical scales currently used to assess spasticity;however inter and intra-rater reliability data from this investigation are lower than those which have previously been reported by experienced users of the ASAS in children with cerebral palsy. Further investigation with a larger sample size is warranted before any firm conclusions may be drawn about the reliability and validity of this tool to assess spasticity in adults with acquired brain injury.展开更多

Calcium ions play a role in the ability of nerves to stimulate muscle contraction. This study aimed to analyze the effect of calcium consumption on the changes of spasticity and the relation of calcium levels in the blood and muscle to the spasticity. The experimental study was conducted on 42 male Sprague-Dawley rats aged 12 - 14 weeks. The 15-d intervention was conducted on six groups of spastic rats by administering 20 g of feed containing 50 mg, 100 mg, and 200 mg of calcium, it also received 100 mg, 200 mg, and 300 mg of calcium lactate supplementation. The experimental rats were induced with 80 mg/kg BW of Erythrocin B through the tail vein to make them spastic. This study showed a tendency of increased spasticity along with the increased dose of calcium given to the subjects. There were significant differences (p = 0.007) in changes in spasticity between groups. The significant differences (p = 0.02) in changes in blood calcium levels. The Spearman’s correlations test on the changes in blood calcium levels and changes in spasticity showed a positive coefficient correlation (r = 0.097) with a p-value of 0.54. An increase in blood calcium levels and a large decrease in spasticity were found in the group receiving 100 mg calcium intake in 20 g of feed. The calcium levels in muscles had a significant correlation with spasticity (p = 0.038, r = 0.810). The calcium levels in the muscle had a strong correlation with blood calcium levels (p = 0.041, r = 0.748). The biggest decrease in spasticity occurred after 100 mg of calcium were given to the rats for 15 days, and it was considered as an optimal dose. The calcium levels in the muscles had a strong correlation with blood calcium levels and the spasticity of the spastic rats.展开更多

Botulinum toxin(BTX) has recently been reported as an efficacious therapeutic agent for the treatment of spasticity. Systematic review and meta-analysis studies have demonstrated that BTX therapy after stroke reduces spasticity and increases physical activity capacity and performance levels. Moreover, BTX can be used as an adjuvant in physiotherapy. Several studies have confirmed that the combination of BTX therapy and physiotherapy improves motor recovery. However, to date, only a few such combination studies have been conducted and their findings are considered preliminary and controversial. Therefore, future studies are required to determine the appropriate combination of treatment methods that will aid motor recovery.展开更多

Twenty-five spastic hamstring muscles were divided in four groups. Group I: 500 pulses, Group II: 1, 000 pulses, Group III: 1, 500 pulses, and Group IV: 2, 000 pulses. Australian Spasticity Assessment Scale (ASAS) was measured at four different time points (pre-ESWT, post-ESWT, 2 weeks post-ESWT, and 4 weeks post-ESWT).Results All four groups showed improvement in ASAS relative to pre-treatment, although only significant in Group III (1, 500 pulses). There were no statistically significant differences in ASAS between all four groups in pre-ESWT [|2(2)=3.907,P=0.272], immediately post-ESWT [|2(2)=1.250,P=0.741], 2 weeks post-ESWT vs pre-ESWT [|2(2)=3.367,P=0.338], and 4 weeks post-ESWT vs pre-ESWT [|2(2)=1.566,P=0.667].Conclusion The effect of rESWT on spastic hamstring in children with spastic CP is not dependent on the number of pulses.展开更多
文摘Objective:To analyze the impact of comprehensive rehabilitation therapy of traditional Chinese medicine(TCM)(based on modern rehabilitation training)on the spasticity and motor function in stroke patients with hemiplegia.Methods:Seventy-nine stroke and hemiplegia patients admitted to the hospital from June 2021 to June 2023 were selected and randomly divided into a control group(39 cases)using modern rehabilitation training,and an observation group combined with comprehensive TCM rehabilitation therapy(40 cases),over 1 month.The clinical index data of the two groups were compared.Results:There were differences in the clinical index data between the two groups.The total effective rate after 2 treatment in the observation group(92.50%)was higher than that of the control group(74.36%)(χ^(2)=4.727,P<0.05).All central sensitization inventory(CSI)and stroke quality of life(PRO)scores in both groups were lower after treatment,with the observation group having lower scores as compared to the control group(P<0.05).The scores of FMA(upper limbs,lower limbs),Barthel index scores,and Functional Ambulation Categories(FAC)scores of both groups increased after treatment,with the observation group having higher scores as compared to the control group(P<0.05).Conclusion:Comprehensive TCM rehabilitation therapy had a significant therapeutic effect on patients with hemiplegia after stroke.It improved the patient’s spasticity,limb movement,and walking function.Their daily living abilities and quality of life were also enhanced.

文摘Spinal cord injury is a severe and devastating disease,and spasticity is a common and severe complication that is notoriously refractory to treatment.However,the pathophysiological mechanisms underlying spasticity and its development remain largely unknown.The goal of the present study was to find differences,if any,in metabolites of the left precentral gyrus and basal ganglia of patients who have spinal cord injury with or without spasticity,and to explore the relationship between the brain metabolite concentrations and clinical status.Thirty-six participants were recruited for magnetic resonance spectroscopic examination:23 with spinal cord injury(12 with spasticity and 11 without spasticity)and 13 healthy controls.We acquired localized proton spectra from the precentral gyrus and basal ganglia via 10 mm^(3) voxels.Notably,univariate linear regression analysis demonstrated that the lower that the N-acetylaspartate concentration(a marker for neuronal loss)was in the precentral gyrus of the patients,the lower their ASIA(American Spinal Injury Association)light-touch scores,pinprick scores,and motor scores.Additionally,longer durations of injury were associated with higher N-acetylaspartate levels in the precentral gyrus.Compared with the healthy participants and patients without spasticity,N-acetylaspartate levels in the patients with spasticity were significantly lower in both the precentral gyrus and basal ganglia.Lower N-acetylaspartate levels also correlated with greater sensory and motor dysfunction in the patients who had spinal cord injury with spasticity.

文摘[Objectives]To investigate the spasticity of rat tail and the expression of dopamine receptor-1(DRD1)mRNA in the spinal cord after spinal cord injury(SCI)induced tail spasticity in rats.[Methods]Adult male Wistar rats were randomly divided into Sham group and SCI group.The second sacral spinal cord(S2)segment of SCI rats was completely transected.60 d after operation,the rat tail spasticity was scored,and then the spinal cord tissues below the level of S2 spinal cord transection were taken.The expression of DRD1 mRNA in the sacrococcygeal spinal cord was detected by qPCR.In addition,3 normal rats were used for DAR/neuronal nuclei(NeuN)and DRD1/choline acetyltransferase(ChAT)immunofluorescence staining to study the distribution of DRD1 in spinal cord and the properties of DRD1 positive cells.[Results]60 d after operation in SCI group,the tail spasticity of rats developed fully,and the symptoms of spasticity were typical.qPCR results showed that the expression of DRD1 mRNA in SCI group was significantly lower than that in Sham group(P<0.05).DRD1 was widely distributed in the dorsal horn,intermediate zone and ventral horn at the sacrococcygeal end of the rat spinal cord.[Conclusions]The decrease of DRD1 mRNA expression after SCI may be related to the occurrence and development of spasticity.
文摘We studied the microselective neurotomy (MSN) and its advantages to alleviate disabling spasticity. The best indication for MSN is focal spasticity. We performed 298 MSN, 87 nerves on the upper limb, 211 nerves on the lower limb) in 68 patients. The initial causes were: stroke, cranial trauma, postoperative complications and multiple sclerosis. MSN procedures were performed on the median nerve (n = 40) for wrist and finger flexion;musculo-cutaneus nerve (n = 38) for elbow flexion;ulnaris nerve (n = 9) for cubital deviation of the hand;gastrocnemius nerve (n = 98) and soleus nerve (n = 49) for equinus foot, tibial posterior nerve (n = 45) for varus foot, and fascicles (or bundles) of the flexor digitorum for “claw” toes (n = 19). The main preoperative test to identify the responsible nerve was a neuromuscular block with local anesthesia (lidocaine or bupivacaine) injected into the site of the nerve connecting the spastic muscle. During surgery, the identified nerve was exposed and its epineurium opened. Nerve bundles were teased apart into individual rootlets and a number of rootlets cut were previously planned, according to the spasticity. Follow-up was performed for up to 10 years, with a mean period of 29 months. Results demonstrated a reduction of limb spasticity of 2 to 3 points: modified Ashworth scale (MAS). Pain and clonus were also diminished in the affected limb. In some cases, voluntary movement was once again possible. MSN is a useful alternative in those cases of focal spasticity where physiotherapy and nerve block with botulinum toxin or phenol no longer produce satisfactory results.

文摘The effect of high-frequency repetitive transcranial magnetic stimulation(r TMS) on potassium-chloride cotransporter-2(KCC2) protein expression following spinal cord injury(SCI) and the action mechanism were investigated. SCI models were established in SD rats. Five groups were set up randomly: normal control group, SCI 7-day(7 D) model group, SCI 14-day(14 D) model group, SCI-7 DrTMS group and SCI-14 DrTMS group(n=5 each). The rats in SCI rTMS groups were treated with 10 Hz rTMS from 8 th day and 15 th day after SCI respectively, once every day, 5 days every week, a total of 4 weeks. After the model establishment, motor recovery and spasticity alleviation were evaluated with BBB scale once a week till the end of treatment. Finally, different parts of tissues were dissected out for detection of variations of KCC2 protein using Western blotting and polymerase chain reaction(PCR) technique. The results showed that the BBS scores after treatment were significantly higher in SCI-7 DrTMS group than in SCI-14 DrTMS group(P<0.05). As compared with normal control groups, The KCC2 protein in SCI model groups was down-regulated after SCI, and the decrease was much more significant in SCI-14 D model group than in SCI-7 D group(P<0.05). As compared with SCI model groups, KCC2 protein in rTMS groups was up-regulated after the treatment(P<0.05). The up-regulation of KCC2 protein content and expression was more obvious in SCI-7 DrTMS group than in SCI-14 DrTMS group(P<0.05). It was concluded that 10 Hz rTMS can alleviate spasticity in rats with SCI, which might be attributed to the up-regulation of KCC2 protein. It was also suggested that the high-frequency rTMS treatment after SCI at early stage might achieve more satisfactory curative effectiveness.
文摘BACKGROUND Spasticity affects a large number of children,mainly in the setting of cerebral palsy,however,only a few paediatric neurosurgeons deal with this problem.This is mainly due to the fact that until 1979,when Fasano has published the first series of selective dorsal rhizotomy(SDR),neurosurgeons were able to provide such children only a modest help.The therapy of spasticity has made a great progress since then.Today,peroral drugs,intramuscular and intrathecal medicines are available,that may limit the effects of the disease.In addition,surgical treatment is gaining importance,appearing in the form of deep brain stimulation,peripheral nerve procedures and SDR.All these options offer the affected children good opportunities of improving the quality of life.CASE SUMMARY A 15-year old boy is presented that was surgically treated for spasticity as a result of cerebral palsy.Laminotomy at L1 level was performed and L1 to S1 nerve roots were isolated and divided in smaller fascicles.Then,the SDR was made.CONCLUSION We describe a patient report and surgical technique of SDR that was performed in Slovenia for the first time.
文摘No definite consensus has currently been reached regarding the safety and efficacy of low-or high-frequency repetitive transcranial magnetic stimulation in the treatment of post-stroke muscle spasticity.The latest research indicates that when combined with local injections of botulinum toxin type A,it is more effective on post-stroke muscle spasticity than local injections of botulinum toxin type A alone.We designed a prospective,single-center,non-randomized,controlled clinical trial to investigate the safety and effica cy of different frequencies of repetitive transcranial magnetic stimulation combined with local injections of botulinum toxin type A in treating post-stroke lower limb muscle spasticity to determine an optimal therapeutic regimen.This trial will enroll 150 patients with post-stroke muscle spasticity admitted to the Department of Rehabilitation Medicine at the First Affiliated Hos pital of China Medical Unive rsity.All enrolled patients will undergo ro utine rehabilitation training and will be divided into five groups in-30 per group) according to the particular area of cerebral infa rction and treatment methods.G roup A:Patients with massive cerebral infarction will be given local injections of botulinum toxin type A and low-frequency(1 Hz)repetitive transcranial magnetic stimulation on the contralate ral side;G roup B:Patients with non-massive cerebral infarction will be given local injections of botulinum toxin type A and high-frequency(10-20 Hz) re petitive transcranial magnetic stimulation on the affected side;G roup C:Patients with massive/non-massive cerebral infarction will be given local injections of botulinum toxin type A;G roup D:Patients with massive cerebral infarction will be given low-frequency(1 Hz) repetitive transcranial magnetic stimulation on the contralate ral side;and G roup E:Patients with non-massive cerebral infa rction will be given high-frequency(10-20 Hz) repetitive transcranial magnetic stimulation on the affected side.The primary outcome measure of this trial is a modified Ashwo rth scale score from 1 day before treatment to 12 months after treatment.Secondary outcome measures include Fugl-M eyer Assessment of Lower Extremity,Visual Analogue Scale,modified Barthel index,and Berg Balance Scale scores for the same time as specified for primary outcome measures.The safety indicator is the incidence of adverse events at 3-12 months after treatment.We hope to draw a definite conclusion on whether there are diffe rences in the safety and efficacy of low-or high-frequency repetitive transcranial magnetic stimulation combined with botulinum toxin type A injections in the treatment of patients with post-stroke lower limb spasticity under strict grouping and standardized operation,thereby screening out the optimal therapeutic regimen.The study protocol was approved by the Medical Ethics Committee of the First Affiliated Hospital of China Medical University(approval No.[2021] 2021-333-3) on August 19,2021.The trial was registe red with the Chinese Clinical Trial Registry(Registration No.ChiCTR2100052180) on October 21,2021.The protocol version is 1.1.
文摘BACKGROUND Cockayne syndrome(CS)is a rare inherited disease characterized by progressive motor symptoms including muscle weakness,joint contracture,ataxia,and spasticity.Botulinum neurotoxin type A has been used for conditions such as dystonia and spasticity,but it has rarely been used in patients with CS.CASE SUMMARY We report a 6-year-and-9-mo old girl diagnosed with CS who received an injection of botulinum neurotoxin type A to manage her difficulty with walking.A total dose of 210 units of botulinum neurotoxin type A was administered into the bilateral tibialis posterior and gastrocnemius muscles.To evaluate the treatment effects on spasticity,joint contracture,pain,and ataxia,measurement tools including the Modified Ashworth Scale,the passive range of motion,the Faces Pain Scale-Revised,and the Scale for the Assessment and Rating of Ataxia,were employed.The first week after the injection,the Modified Ashworth Scale score for the plantar flexors and foot invertors improved bilaterally,along with advancements in the passive range of motion of the bilateral ankles and a lower score for the Faces Pain Scale-Revised.These treatment effects persisted to the 8th week post-injection,but returned to baseline values at the 12th week post-injection,except for the pain scale.CONCLUSION Botulinum toxin injection can thus be considered as a treatment option for lower extremity spasticity,joint contracture,and pain derived from CS.
文摘Objective: This study investigated the inter- and intra-rater reliability of the Australian Spasticity Assessment Scale (ASAS) in adults with unilateral hypertonia following acquired brain injury. The ASAS has been shown to be superior to other clinical tools for the assessment of spasticity in children with cerebral palsy but reliability has not been previously examined in adults. Method: Four muscle groups were rated on one occasion by four assessors using the ASAS in sixteen adults with unilateral hypertonia following acquired brain injury. Twelve participants returned one week later for reassessment by the same assessors. Results: Overall inter-rater reliability of the ASAS using a quadratic weighted Kappa was moderate (Kqw 0.58) with ranges from moderate to good (Kqw 0.42 - 0.70). Agreement between raters was greatest for soleus muscle and least for wrist flexors. Overall intra-rater reliability of each of the four raters was moderate to good (Kqw 0.48 - 0.79). Agreement within raters was greatest for soleus muscle and least for biceps muscle. Conclusions: The ASAS may represent an appropriate alternative to the clinical scales currently used to assess spasticity;however inter and intra-rater reliability data from this investigation are lower than those which have previously been reported by experienced users of the ASAS in children with cerebral palsy. Further investigation with a larger sample size is warranted before any firm conclusions may be drawn about the reliability and validity of this tool to assess spasticity in adults with acquired brain injury.
文摘Spasticity is a stiff muscle condition because the muscles receive impulses continuously. Calcium ions play a role in the ability of nerves to stimulate muscle contraction. This study aimed to analyze the effect of calcium consumption on the changes of spasticity and the relation of calcium levels in the blood and muscle to the spasticity. The experimental study was conducted on 42 male Sprague-Dawley rats aged 12 - 14 weeks. The 15-d intervention was conducted on six groups of spastic rats by administering 20 g of feed containing 50 mg, 100 mg, and 200 mg of calcium, it also received 100 mg, 200 mg, and 300 mg of calcium lactate supplementation. The experimental rats were induced with 80 mg/kg BW of Erythrocin B through the tail vein to make them spastic. This study showed a tendency of increased spasticity along with the increased dose of calcium given to the subjects. There were significant differences (p = 0.007) in changes in spasticity between groups. The significant differences (p = 0.02) in changes in blood calcium levels. The Spearman’s correlations test on the changes in blood calcium levels and changes in spasticity showed a positive coefficient correlation (r = 0.097) with a p-value of 0.54. An increase in blood calcium levels and a large decrease in spasticity were found in the group receiving 100 mg calcium intake in 20 g of feed. The calcium levels in muscles had a significant correlation with spasticity (p = 0.038, r = 0.810). The calcium levels in the muscle had a strong correlation with blood calcium levels (p = 0.041, r = 0.748). The biggest decrease in spasticity occurred after 100 mg of calcium were given to the rats for 15 days, and it was considered as an optimal dose. The calcium levels in the muscles had a strong correlation with blood calcium levels and the spasticity of the spastic rats.
文摘Spasticity after the occurrence of stroke induces limb deformity, functional disability and/or pain in patients, which limits their activities of daily living and deteriorates their quality of life. Botulinum toxin(BTX) has recently been reported as an efficacious therapeutic agent for the treatment of spasticity. Systematic review and meta-analysis studies have demonstrated that BTX therapy after stroke reduces spasticity and increases physical activity capacity and performance levels. Moreover, BTX can be used as an adjuvant in physiotherapy. Several studies have confirmed that the combination of BTX therapy and physiotherapy improves motor recovery. However, to date, only a few such combination studies have been conducted and their findings are considered preliminary and controversial. Therefore, future studies are required to determine the appropriate combination of treatment methods that will aid motor recovery.
文摘Botulinum toxin found its way into a lot of medical treatments improving the quality of life in many clinical situations.When treating spasticity,this toxin is injected in the affected muscle to decrease its tension and hyperactivity.The isolation of the affected muscles for injection is done either by anatomical palpation of the muscle which is also known as non-guided injection technique,or by using the ultrasound or the electromyography also known guided injection technique.In this study which is a prospective observational study that included patients over a 6 months period,28 patients aged between 2 and 78 years,with spasticity na?ve to botulinum toxin injections or had already been injected more than 3 months ago,were injected using guided injection technique.The optimal doses of botulinum toxin were administered based on the age,the severity of the condition,and affected muscle groups.In pediatric population these were also calculated according to the body weight.All patients were evaluated pre and 4 weeks post injection using the MAS Score(Modified Ashworth Scale).Statistical analysis showed a very significant response to treatment as compared to the pre-injection condition,for upper limbs,lower limbs,and all muscle groups with almost absent significant local or systemic side effects(with a p value less than 0.001).Conclusion:guided techniques for botulinum toxin injections showed a great efficacy in the treatment of spasticity along with no regional or systemic side effects and are relatively well tolerated by patients.This finding leads to a better management of spasticity and to a decrease in oral medication intake and secondarily a decrease in their possible side effects.

文摘Background:Warm acupuncture,or warm-needle acupuncture,is a traditional external treatment widely used in China for thousands of years.However,the effects of different treatment times on limb spasticity post-stroke have not been evaluated.Methods:We searched PubMed,Embase,the Cochrane Library,the Web of Science,the China National Knowledge Infrastructure,the Chinese Scientific and Journal Database,the Wanfang database,and the Chinese Biomedical Literature Database from inception to May 21st,2020,to seek information regarding randomized controlled trials studying warm-needle acupuncture for limb spasticity post-stroke.Two authors selected 24 studies fitting the eligibility criteria and developed this systematic review and meta-analysis.Results:Warm-needle acupuncture is shown to be more effective than other treatments used in the control groups(odds ratio(OR)=3.61,95%confidence intervals(CI)(2.51,5.19),P<0.001).This treatment decreased limb spasticity as assessed with the Modified Ashworth Scale(mean differences(MD)=−0.78,95%CI(−1.00,−0.56),P<0.001)and the Clinic Spasticity Index(MD=1.06,95%CI(0.51,1.60),P=0.0002),improved sensorimotor impairments according to the Fugl-Meyer Assessment(MD=9.51,95%CI(6.99,12.03),P<0.001),and improved activities of daily living according to the Barthel Index(MD=9.70,95%CI(6.27,13.12),P<0.001).Subgroup analysis based on the length of the treatment using the Modified Ashworth Scale,Fugl-Meyer Assessment,and Barthel Index showed better outcomes for patients who received more than 20 days of treatments(P<0.001).Conclusion:Warm-needle acupuncture is an effective treatment for limb spasticity post-stroke.A treatment frequency of more than 20 days appears to have better effectiveness than that of less than 20 days.

文摘OBJECTIVE:To evaluate the efficacy of Baishao Luoshi decoction(白芍络石方,BD)on synaptic plasticity in rats with post stroke spasticity(PSS),and to study the mechanism behind the action.METHODS:The PSS model of rat was established by middle cerebral artery occlusion(MCAO).The neurological deficit symptoms were evaluated by modified neurological deficit score(mN SS).Muscle tension were evaluated by Modified Ashworth score(MAS).Transmission electron microscopy(TEM)was used to observe the synaptic ultrastructure.The expression of synaptic plasticity-related protein brain derived neurotrophic factor(BDNF),growth associated protein-43(GAP43),synaptophysin(p38)and microtubule-associated protein 2(MAP2)in the brain tissue around the infarct were detected by Western blotting.RESULTS:We found that mNSS were significantly improved and limb spasticity was ameliorated treated by BD.The thickness of postsynaptic density and the synaptic curvature increased significantly.The expression of synaptic plasticity-related protein BDNF,GAP43,p38,MAP2 in the brain tissue around the infarct were raised remarkably after treated by BD.CONCLUSIONS:Alleviating PSS by BD may be related to rescuing the synaptic plasticity,which provides a probable new therapeutic method for PSS.

文摘Traumatic brain inju ry-induced unfavorable outcomes in human patients have independently been associated with dysregulated levels of monoamines,especially epinephrine,although few preclinical studies have examined the epinephrine level in the central nervous system after traumatic brain injury.Epinephrine has been shown to regulate the activities of spinal motoneurons as well as increase the heart rate,blood pressure,and blood flow to the hindlimb muscles.Therefore,the purpose of the present study was to determine the impact of repeated blast-induced traumatic brain injury on the epinephrine levels in seve ral function-s pecific central nervous system regions in rats.Following three repeated blast injuries at 3-day intervals,the hippocampus,motor cortex,locus coeruleus,vestibular nuclei,and lumbar spinal cord were harvested at post-injury day eight and processed for epinephrine assays using a high-sensitive electrochemical detector cou pled with high-performance liquid chromatography.Our results showed that the epinephrine levels were significantly decreased in the lumbar spinal cord tissues of blast-induced traumatic brain injury animals compared to the levels detected in age-and sex-matched sham controls.In other function-specific central nervous system regions,although the epinephrine levels were slightly altered following blast-induced tra u matic brain injury,they were not statistically significant.These results suggest that blast injury-induced significant downregulation of epinephrine in the lumbar spinal cord could negatively impact the motor and cardiovascular function.This is the first repo rt to show altered epinephrine levels in the spinal cord following repetitive mild blast-induced traumatic brain injury.
文摘Purpose To evaluate the efficacy and safety of radial extracorporeal shock wave therapy (rESWT) according to total number of pulses on hamstring muscle spasticity in children with spastic type cerebral palsy (CP).Methods This study is a randomized controlled trial consisting of thirteen patients with spastic CP, 9 males and 4 females, aged 5 to 14 years (mean age 9.2). Twenty-five spastic hamstring muscles were divided in four groups. Group I: 500 pulses, Group II: 1, 000 pulses, Group III: 1, 500 pulses, and Group IV: 2, 000 pulses. Australian Spasticity Assessment Scale (ASAS) was measured at four different time points (pre-ESWT, post-ESWT, 2 weeks post-ESWT, and 4 weeks post-ESWT).Results All four groups showed improvement in ASAS relative to pre-treatment, although only significant in Group III (1, 500 pulses). There were no statistically significant differences in ASAS between all four groups in pre-ESWT [|2(2)=3.907,P=0.272], immediately post-ESWT [|2(2)=1.250,P=0.741], 2 weeks post-ESWT vs pre-ESWT [|2(2)=3.367,P=0.338], and 4 weeks post-ESWT vs pre-ESWT [|2(2)=1.566,P=0.667].Conclusion The effect of rESWT on spastic hamstring in children with spastic CP is not dependent on the number of pulses.
