Since SN occasionally resembles the clinicopathological presentation of malignant melanoma (MM), it presents a diagnostic challenge, especially on glabrous skin. Past reports suggest that several genetic aberrations are associated with specific clinicopathological subtypes of melanocytic tumors. Immunohistochemistry can provide a clue to the presence or absence of a molecular aberration typical of Spitz tumors. We describe a case of a plantar SN with genetic analysis, including anaplastic lymphoma kinase (ALK), ROS proto-oncogene 1 (ROS1), BRAF (V600E) protein, and BRCA1-associated protein-1 (BAP1). However, we were not able to detect a characteristic gene aberration. To the best of our knowledge, no genetic aberrations in plantar SN cases have been reported. A comprehensive understanding of tumor genomics is expected to play an essential role in the classification of melanocytic tumors. Further genetic research on plantar SN is required to establish new criteria for distinguishing between SN and MM.展开更多

Methods: This study was carried out on 16 patients, 9 men and 7 women, with average age 47.5, diagnosed with plantar fasciosis, who were treated through ultrasound-guided partial plantar fasciotomy using multiple perforations. Clinical assessments and ultrasounds of all patients were carried out before treatment, after a week, then after 1, 3 and 12 months. For the clinical assessment the Visual Analogue Scale (VAS) and the Foot and Ankle Disability Index (FADI) were used. Results: There was significant progress at 95% (Greenhouse-Geisser p < 0.001) of the VAS and the FADI during the study. We had no nerve or other complications: paraesthesia of the entry portal or vascular lesions. Conclusion: Ultrasound- guided partial plantar fasciotomy using multiple perforations is a safe technique, with very satisfactory preliminary results, reducing recovery times and time off work. The technique can be performed in the specialist’s consultation room with local anaesthesia, without the need for stitches and with very fast recovery, thus reducing costs. It can be performed on patients with underlying pathology such as diabetes mild to moderate, vascular insufficiency, heart disease or other comorbidities, so this technique could be an improvement on other open plantar fasciotomy surgical techniques.展开更多

The spatiotemporal parameters of walking and the parameters of plantar pressure can be obtained using a plantar pressure analysis system. Previous studies have reported step asymmetry in patients with bilateral SCI. However, the asymmetry of other parameters in patients with SCI has not been reported. This was a prospective, cross-sectional study, which included 23 patients with SCI, aged 48.1 ± 14.5 years, and 28 healthy subjects, aged 47.1 ± 9.8 years. All subjects underwent bare foot walking on a plantar pressure measurement device to measure walking speed and spatiotemporal parameters. Compared with healthy subjects, SCI patients had slower walking speed, longer stride time and stance time, larger stance phase percentage, and shorter stride length. The peak pressures under the metatarsal heads and toe were lower in SCI patients than in healthy subjects. In the heel, regional impulse and the contact area percentage in SCI patients were higher than those in healthy subjects. The symmetry indexes of stance time, step length, maximum force, impulse and contact area were increased in SCI patients, indicating a decline in symmetry. The results confirm that the gait quality, including spatiotemporal variables and plantar pressure parameters, and symmetry index were lower in SCI patients compared with healthy subjects. Plantar pressure parameters and symmetry index could be sensitive quantitative parameters to improve gait quality of SCI patients. The protocols were approved by the Clinical Research Ethics Committee of Shengjing Hospital of China Medical University(approval No. 2015 PS54 J) on August 13, 2015. This trial was registered in the ISRCTN Registry(ISRCTN42544587) on August 22, 2018. Protocol version: 1.0.展开更多

Methods： Thirteen male recreational runners were required to run at 12 km/h velocity on concrete, synthetic track, natural grass, a normal treadmill, and a treadmill equipped with an ethylene vinyl acetate （EVA） cushioning underlay （treadmill_EVA）, respectively. An in-shoe plantar pressure system and an accelerometer attached to the tibial tuberosity were used to record and analyze the characteristics of plantar pressure and tibial impact during running. Results： The results showed that there were no significant differences in the 1 st and 2nd peak plantar pressures （time of occurrence）, pressure-time integral, and peak pressure distribution for the concrete, synthetic, grass, and normal treadmill surfaces. No significant differences in peak positive acceleration were observed among the five tested surface conditions. Compared to the concrete surface, however, running on treadmillEVA showed a significant decrease in the 1st peak plantar pressure and the pressure time integral for the impact phase （p 〈 0.05）. These can be further ascribed to a reduced peak pressure observed at heel region （p 〈 0.05）. Conclusion： There may not be an inevitable relationship between the surface and the lower-limb impact in runners. It is, however, still noteworthy that the effects of different treadmill surfaces should be considered in the interpretation of plantar pressure performance and translation of such results to overground running.展开更多

Excited areas of ankle active dorsiflexion involved the bilateral primary motor area and the primary somatosensory area, as well as the bilateral supplementary sensory area, the primary visual area, the right second visual area, and the vermis of cerebellum. Excited areas of ankle active plantar flexion included the ipsilateral supplementary motor area, the limbic system, and the contralateral corpus striatum. Fine movements of the cerebral cortex control the function of the ankle dorsiflexion to a larger extent than ankle plate flexion, and the function of ankle plate flexion is more controlled by the subcortical area.展开更多

The most common symptom of this condition is pain. There are many treatment options to deal with this condition, such as conservative therapy, medications</span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;"> and surgical interventions in rare cases. This case study aims to investigate the potential impact of pain neuroscience education (PNE), combined with a conventional Physical Therapy (PT) program on a 37-year-old-patient with chronic plantar fasciitis. Case description: A 37-year-old male health care professional presented to an outpatient physical therapy clinic with a diagnosis of chronic PF for around two years. The participant had tried several treatment options with no improvement of his symptoms. After undergoing a physical therapy evaluation, he was given a plan of care for twelve sessions by a skilled physical therapist for a six-week period, with each session consisting of 30 minutes of conventional PT, followed by 5 to 15 minutes of PNE. Results: After completing the prescribed plan of care, the patient reported </span><span style="font-family:Verdana;">a </span><span style="font-family:Verdana;">reduction in subjective symptoms via the Visual Analog Scale (VAS). He also reported improvement with symptoms and functional independence via the Foot Function Index (FFI). The patient reported no change in </span><span style="font-family:Verdana;">the </span><span style="font-family:Verdana;">quality of sleep via Pittsburg Sleep Quality Index (PSQI). Lastly, he demonstrated no objective improvement in foot pressure with the Navicular Drop Test. Discussion: This case report indicates that PNE, combined with conventional PT for PF can have a positive impact on subjective pain and foot function. PNE should involve many topics about the physiology of pain and the nervous system and should be administered by a certified therapeutic pain specialist. Further studies are recommended to investigate the impact of this intervention in combination with traditional PT for PF in larger populations.</span>展开更多

A total of 5 types of socks,including 3 types of diabetic socks and 2 types of daily /sports socks of various structures are studied. The effects of sock fabrication and design on plantar pressure redistribution that resulting in increasing the underfoot contact area and reducing the risk of pressure ulceration,as well as foot skin temperature and humidity, are examined. The results reveal that regardless of the different knitting structure,thickness and airspace ratio of the sock,both diabetic and daily /sports socks can effectively reduce high plantar pressure on the rear foot,and re-distribute the pressure to other foot regions,like the metatarsal heads. The effects of fabrication and knitting structure on pressure reduction and redistribution are not apparent in this study. However,they have a major impact on the control of foot skin temperature and humidity. The results of the study provide a reference for optimizing the design and functional performance of socks for patients with diabetes.展开更多

The aim of this study was to investigate the effects of orthopaedic soles on the body posture. Methods. Forty-eight runners (21 men and 28 women) maintained a standing-up position on both feet with bare feet with neutral soles and orthopedic soles which contained bilaterally a podiatrist element of 3 mm height behind the metatarsal heads (Metatarsal Retro Capital Bar, MRCB). Stabilometric, plantar pressure and kinematic data in the sagittal plane on both sides were measured at 40 and 60 Hz, respectively. The position of the center of pressure on the anteroposterior axis (YCoP), the forefoot plantar pressure (FPP) and the anteroposterior position of the knee (Yk), the hip (YH), the shoulder (YS) and the ears (YE) with respect to the vertical axis passing through the joint of the ankle were determined for each experimental condition. Findings. The addition of a MRCB orthopedic element induced in backward displacement of CoP, hip, shoulder and ears (p CoP and FPP changes were significantly correlated with YH, YS and YE changes (p Conclusion. These results suggest that the addition of an orthopedic element located behind the metatarsal heads influences the overall position of the body and can help podiatrist in the care of their patients.展开更多

Here we reported a case of plantar lichen planus where there was a history of discharge of dark grains from the sole of foot and diagnosing the disease as eumycetoma of dark grains repeated antifungal therapy could not resolve the lesions and histopathologically it showed the classical pictures of lichen planus. Collaborating the clinical and histological features we have diagnosed the case as perforating lichen planus but Verhoeff-Van Gieson stain could not elucidate the perforating channel which ot difficult to delineate and often missed. So, we have put the diagnosis of plantar lichen planus and treated with intramuscular triamcinolone and the lesions resolved.展开更多

It has long been ...The purpose of this literature review is better comprehension about role of the plantar fascia on the structure （arch height） and function （adaptation） of the foot and ankle in living individual. It has long been accepted that plantar fascia supports medial longitudinal arch both in weight bearing and locomotion. Literatures were reviewed through a systematic method. First, current knowledge about plantar fascia properties were established and analyzed; second, previous studies and methods to study plantar fascia were analyzed; finally, the problems in previous researches to study plantar fascia were argued. It was found that plantar fascia affects foot arch and foot adaptation under vertical load in living individual. In accordance with results of this literature review, the modification of plantar fascia thickness under vertical load is specific property of the plantar fascia in living individual. Additionally, the specific property of plantar fascia can help clinicians to diagnose the necessity of plantar fascia assessment along its length.展开更多

This study aimed to compare the strength of foot muscles, dynamic balance, and peak plantar pressure between diabetic patients before developing polyneuropathy and healthy peers. Methods: 21 people, 11 diabetic patients and 10 age-matched healthy peers, were included in the study. A manual muscle tester (model 01163 Lafayette) was used to assess muscle strength. Pedobarography was the device to determine the distribution of plantar pressure into nine regions of foot. Dynamic balance was also measured by using a mobile platform (Techno-body, PK 200 WL, Italy). Results: Diabetic and control groups had similar muscle strength and dynamic balance (p > 0.05). Most of the plantar pressure findings were also similar (p > 0.05). There were significant differences in only two regions of foot between two groups (p < 0.05). Conclusion: Diabetes Mellitus is not a factor influencing balance and muscle strength before polyneuropathy. However, it is possible to state that it may negatively affect the distribution of plantar pressure so clinians should assess and treat this distribution in the patients with DM.展开更多

It has been found that high PPP correlates to the common foot deformities including pes planus/cavus. However, previous studies utilized excessive electronics in gait retraining, which is challenging toimplement daily especially when device cleaning, flexibility and portability are considered. Therefore, this studyinvestigated feasibility of a novel unpowered gait retraining for reducing high PPP. Twelve potential participantsidentified for investigation through a baseline PPP evaluation with Novel Pedar-x system. Participants received asingle session for the gait retraining with pebbles in the form of rigid spherical inserts (RSI) placed in locations ofhigh PPP inside the deformable insole. This provides tactile cues alerting the participants to alter their gait toreduce excess PPP. The PPP values were tracked in weekly follow-up sessions for 6 weeks. The results demonstrated that participants responded to RSI altering their gait to reduce PPP and maximum force by 14% and 10.5%after six weeks respectively. This study is valuable for physicians in reducing PPP when non-electronics arerequired.展开更多

文摘Forefoot pain is common in high-heeled shoe wearers due to the high pressure caused by the center of body mass moving forward and the increased arch height with heel elevation.Sufficient arch support could reduce the high pressure over forefoot.However,too much arch support could lead to abnormal foot alignment and pain over midfoot.Little information is reported on the relationship among plantar arch height,shank curve design and plantar pressure.This study aimed at quantifying the plantar arch height changes at different heel heights and investigating the effect of shank curve on plantar pressure distribution.The plantar arch height increased to（7.6±1.3） mm at heel height of 75 mm.The Chinese standard suggests the depth of last should be 8.5 mm for heel height of 75 mm.When a shank curve with higher depth of last（11 mm） was used,the peak pressure over forefoot further decreased in midstance phase,which might ease the forefoot problems,while the peak pressure over midfoot increased but not exceeded the discomfort pressure thresholds.To achieve a more ideal pressure distribution in high-heeled shoes,a higher than expected depth of last would be suggested that would not cause discomfort over midfoot.

Methods： Thirteen male recreational runners were required to run at 12 km/h velocity on concrete, synthetic track, natural grass, a normal treadmill, and a treadmill equipped with an ethylene vinyl acetate （EVA） cushioning underlay （treadmill_EVA）, respectively. An in-shoe plantar pressure system and an accelerometer attached to the tibial tuberosity were used to record and analyze the characteristics of plantar pressure and tibial impact during running. Results： The results showed that there were no significant differences in the 1 st and 2nd peak plantar pressures （time of occurrence）, pressure-time integral, and peak pressure distribution for the concrete, synthetic, grass, and normal treadmill surfaces. No significant differences in peak positive acceleration were observed among the five tested surface conditions. Compared to the concrete surface, however, running on treadmillEVA showed a significant decrease in the 1st peak plantar pressure and the pressure time integral for the impact phase （p 〈 0.05）. These can be further ascribed to a reduced peak pressure observed at heel region （p 〈 0.05）. Conclusion： There may not be an inevitable relationship between the surface and the lower-limb impact in runners. It is, however, still noteworthy that the effects of different treadmill surfaces should be considered in the interpretation of plantar pressure performance and translation of such results to overground running.

文摘Changes in activated areas of the brain during ankle active dorsiflexion and ankle active plantar flexion were observed in six healthy subjects using functional magnetic resonance imaging. Excited areas of ankle active dorsiflexion involved the bilateral primary motor area and the primary somatosensory area, as well as the bilateral supplementary sensory area, the primary visual area, the right second visual area, and the vermis of cerebellum. Excited areas of ankle active plantar flexion included the ipsilateral supplementary motor area, the limbic system, and the contralateral corpus striatum. Fine movements of the cerebral cortex control the function of the ankle dorsiflexion to a larger extent than ankle plate flexion, and the function of ankle plate flexion is more controlled by the subcortical area.
文摘<span style="font-family:Verdana;">Background and Purpose: Plantar Fasciitis (PF) is a condition that affects the foot and causes complaints such as pain and stiffness. The most common symptom of this condition is pain. There are many treatment options to deal with this condition, such as conservative therapy, medications</span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;"> and surgical interventions in rare cases. This case study aims to investigate the potential impact of pain neuroscience education (PNE), combined with a conventional Physical Therapy (PT) program on a 37-year-old-patient with chronic plantar fasciitis. Case description: A 37-year-old male health care professional presented to an outpatient physical therapy clinic with a diagnosis of chronic PF for around two years. The participant had tried several treatment options with no improvement of his symptoms. After undergoing a physical therapy evaluation, he was given a plan of care for twelve sessions by a skilled physical therapist for a six-week period, with each session consisting of 30 minutes of conventional PT, followed by 5 to 15 minutes of PNE. Results: After completing the prescribed plan of care, the patient reported </span><span style="font-family:Verdana;">a </span><span style="font-family:Verdana;">reduction in subjective symptoms via the Visual Analog Scale (VAS). He also reported improvement with symptoms and functional independence via the Foot Function Index (FFI). The patient reported no change in </span><span style="font-family:Verdana;">the </span><span style="font-family:Verdana;">quality of sleep via Pittsburg Sleep Quality Index (PSQI). Lastly, he demonstrated no objective improvement in foot pressure with the Navicular Drop Test. Discussion: This case report indicates that PNE, combined with conventional PT for PF can have a positive impact on subjective pain and foot function. PNE should involve many topics about the physiology of pain and the nervous system and should be administered by a certified therapeutic pain specialist. Further studies are recommended to investigate the impact of this intervention in combination with traditional PT for PF in larger populations.</span>
文摘BACKGROUND Synovial sarcoma (SS),a rare malignant soft tissue tumor whose histological origin is still unknown,often occurs in limbs in young people and is easily misdiagnosed.CASE SUMMARY We report a 24-year-old man who sought treatment for plantar pain thought to be caused by a foot injury that occurred 4 years prior.Currently,he had been seen at another hospital for a 1-wk history of unexplained pain in the left plantar region and was treated with acupuncture,a kind of therapy of Chinese medicine,which partly relieved the pain.Because of this,the final diagnosis of biphasic SS was made after two subsequent treatments by pathological evaluation after the last operation.SS is rarely seen in the plantar area,and his history of a left plantar injury confused the original diagnosis.CONCLUSION This study shows that pathological and imaging examinations may play a vital role in the early diagnosis and treatment of SS.

文摘This study aims to evaluate the efficacy of different types of socks for patients with diabetes on reducing in-shoe plantar foot pressure when standing and walking. A total of 5 types of socks,including 3 types of diabetic socks and 2 types of daily /sports socks of various structures are studied. The effects of sock fabrication and design on plantar pressure redistribution that resulting in increasing the underfoot contact area and reducing the risk of pressure ulceration,as well as foot skin temperature and humidity, are examined. The results reveal that regardless of the different knitting structure,thickness and airspace ratio of the sock,both diabetic and daily /sports socks can effectively reduce high plantar pressure on the rear foot,and re-distribute the pressure to other foot regions,like the metatarsal heads. The effects of fabrication and knitting structure on pressure reduction and redistribution are not apparent in this study. However,they have a major impact on the control of foot skin temperature and humidity. The results of the study provide a reference for optimizing the design and functional performance of socks for patients with diabetes.

文摘Plantar pressure distribution of the designed cushioned soles was studied and compared with that of the commercially available sport shoes.A three-dimensional motion measurement system was used to obtain the peak plantar force,the peak plantar pressure,force-time integrals and pressure-time integrals,and one-way analysis of variance was used to analyze the performance of the designed cushioned shoes.The results revealed that in normal walking and jogging states,compared with the commercially available sport shoes,the peak plantar pressure in the heel region decreased by 13.65%and 6.05%,respectively.The peak plantar force decreased by 15.98%and 15.32%,respectively.The force-time integral decreased by 4.36%and 6.83%,respectively,and the pressure-time integral decreased by 10.58%and 11.00%,respectively.In conclusion,the cushioning performance of shoes is related to the exercise mode.For normal walking,the designed cushioned soles absorbed greater impact in the heel region,which was effectively cushioned,whereas in the jogging state,the designed cushioned soles exhibited a favorable cushioning effect in the forefoot region.The designed cushioned soles exhibited cushioning performance through the coupling design of material and structure,which effectively reduced impact force when landing and could optimize plantar pressure distribution.
文摘Objectives. The aim of this study was to investigate the effects of orthopaedic soles on the body posture. Methods. Forty-eight runners (21 men and 28 women) maintained a standing-up position on both feet with bare feet with neutral soles and orthopedic soles which contained bilaterally a podiatrist element of 3 mm height behind the metatarsal heads (Metatarsal Retro Capital Bar, MRCB). Stabilometric, plantar pressure and kinematic data in the sagittal plane on both sides were measured at 40 and 60 Hz, respectively. The position of the center of pressure on the anteroposterior axis (YCoP), the forefoot plantar pressure (FPP) and the anteroposterior position of the knee (Yk), the hip (YH), the shoulder (YS) and the ears (YE) with respect to the vertical axis passing through the joint of the ankle were determined for each experimental condition. Findings. The addition of a MRCB orthopedic element induced in backward displacement of CoP, hip, shoulder and ears (p CoP and FPP changes were significantly correlated with YH, YS and YE changes (p Conclusion. These results suggest that the addition of an orthopedic element located behind the metatarsal heads influences the overall position of the body and can help podiatrist in the care of their patients.
文摘Lichen planus is a common inflammatory disease but its perforating variety is not so common and it has been described in small number of text and articles. Here we reported a case of plantar lichen planus where there was a history of discharge of dark grains from the sole of foot and diagnosing the disease as eumycetoma of dark grains repeated antifungal therapy could not resolve the lesions and histopathologically it showed the classical pictures of lichen planus. Collaborating the clinical and histological features we have diagnosed the case as perforating lichen planus but Verhoeff-Van Gieson stain could not elucidate the perforating channel which ot difficult to delineate and often missed. So, we have put the diagnosis of plantar lichen planus and treated with intramuscular triamcinolone and the lesions resolved.
文摘The purpose of this literature review is better comprehension about role of the plantar fascia on the structure （arch height） and function （adaptation） of the foot and ankle in living individual. It has long been accepted that plantar fascia supports medial longitudinal arch both in weight bearing and locomotion. Literatures were reviewed through a systematic method. First, current knowledge about plantar fascia properties were established and analyzed; second, previous studies and methods to study plantar fascia were analyzed; finally, the problems in previous researches to study plantar fascia were argued. It was found that plantar fascia affects foot arch and foot adaptation under vertical load in living individual. In accordance with results of this literature review, the modification of plantar fascia thickness under vertical load is specific property of the plantar fascia in living individual. Additionally, the specific property of plantar fascia can help clinicians to diagnose the necessity of plantar fascia assessment along its length.
文摘Aims: Diabetes Mellitus (DM) is a metabolic disorder which affects whole systems of human body. This study aimed to compare the strength of foot muscles, dynamic balance, and peak plantar pressure between diabetic patients before developing polyneuropathy and healthy peers. Methods: 21 people, 11 diabetic patients and 10 age-matched healthy peers, were included in the study. A manual muscle tester (model 01163 Lafayette) was used to assess muscle strength. Pedobarography was the device to determine the distribution of plantar pressure into nine regions of foot. Dynamic balance was also measured by using a mobile platform (Techno-body, PK 200 WL, Italy). Results: Diabetic and control groups had similar muscle strength and dynamic balance (p > 0.05). Most of the plantar pressure findings were also similar (p > 0.05). There were significant differences in only two regions of foot between two groups (p < 0.05). Conclusion: Diabetes Mellitus is not a factor influencing balance and muscle strength before polyneuropathy. However, it is possible to state that it may negatively affect the distribution of plantar pressure so clinians should assess and treat this distribution in the patients with DM.
文摘Recently, there has been a growing interest in gait retraining to alter the gait parameters of different populations.In these gait retraining, peak plantar pressure (PPP) was considered as an important parameter of the footbiomechanics. It has been found that high PPP correlates to the common foot deformities including pes planus/cavus. However, previous studies utilized excessive electronics in gait retraining, which is challenging toimplement daily especially when device cleaning, flexibility and portability are considered. Therefore, this studyinvestigated feasibility of a novel unpowered gait retraining for reducing high PPP. Twelve potential participantsidentified for investigation through a baseline PPP evaluation with Novel Pedar-x system. Participants received asingle session for the gait retraining with pebbles in the form of rigid spherical inserts (RSI) placed in locations ofhigh PPP inside the deformable insole. This provides tactile cues alerting the participants to alter their gait toreduce excess PPP. The PPP values were tracked in weekly follow-up sessions for 6 weeks. The results demonstrated that participants responded to RSI altering their gait to reduce PPP and maximum force by 14% and 10.5%after six weeks respectively. This study is valuable for physicians in reducing PPP when non-electronics arerequired.

文摘The medial plantar artery(MPA),as a terminal branch of the posterior tibial artery,provides perfusion to the musculature of the medial compartment of the plantar foot as well as cutaneous branches to the skin.The artery and its perforators serve as the foundation for several flaps based on various soft tissue components for the coverage of small defects of the foot.Most noteworthy is the fasciocutaneous flap,which utilizes the skin and the unique properties of the plantar foot.Understanding the anatomical relationship of the terminal branches of the MPA,the superficial and deep branches,is necessary in determining the type of tissue and the flap design to be utilized for reconstruction.
文摘Objective:To investigate the effect of internal heat acupuncture on the tolerance time of plantar hot plate and the pain threshold of gastrocnemius in rats with chronic myofascial pain syndrome(MPS).Methods:A total of 80 adult Wistar rats were randomly selected to establish chronic MPS rat models,and randomly divided into four groups:control group,acupuncture group,internal heat acupuncture group A,and internal heat acupuncture group B,with 20 rats in each group.The rats in the control group were not given any treatment,and the rats in the acupuncture group were only given acupuncture treatment.The rats in group A were treated with internal heat acupuncture(needle heating up to 42℃),and the rats in group B were treated with internal heat acupuncture(needle heating up to 44℃).The tolerance time of plantar hot plate,the pain threshold of gastrocnemius muscle and the level of tumor necrosis factor-α(TNF-α)were observed and compared before modeling,1 d before treatment,and 1,7 and 14 d after treatment.Results:There were significant differences in hot plate tolerance time,time and interaction among the four groups(P<0.05),as well as in gastrocnemius tenderness threshold,time and interaction among the four groups(P<0.05),and there were also significant differences in TNF-αlevel among the three groups(P>0.05).There were significant differences in the number of electric shocks,time and interaction among the four groups(P<0.05).Conclusion:In contrast to conventional acupuncture treatment,internal heat acupuncture demonstrates greater efficacy in extending the tolerance duration of hot plate exposure and enhancing the pain threshold of the gastrocnemius muscle in rats afflicted with myofascial pain syndrome.Additionally,it accelerates the amelioration of inflammatory markers and motor function.However,it is important to note that the therapeutic impact of internal heat acupuncture may be influenced by its temperature,with 44℃being the most effective in this research.
