Design: Epidemiological study of the prevalence of hand OA in patients with knee osteoarthritis. The Stanford Health Assessment Questionnaire instruments (HAQ);Disabilities of the Arm, Shoulder and Hand* (DASH);grip strength;and finger pinch were utilized, and the upper limbs symptoms were verified at baseline and one year following the educational program. Results: The prevalence of hOA was 23.7% at baseline and 47.4% at one year (incidence of 31.8% per year). The HAQ indicated that patients who did not alter or increased their BMI experienced worsened global strength, whereas patients who reduced BMI improved global strength (p = 0.041). Patients with higher initial BMIs experienced less improvement in the HAQ (r = -0.148, p = 0.041). The DASH results improved, but the right and left tripod grip worsened in all patients, irrespective of BMI change (p < 0.05) or symptoms at baseline and reassessment (p < 0.05). Pinch strength (right and left tripod and left pulp-pulp) was higher in patients without symptoms at baseline (p = 0.048, p = 0.045 and 0.033, respectively). Conclusions: The prevalence of hand OA increased for patients with OA undergoing an educational program irrespective of improved upper function and regardless of BMI change. Patients who decreased their BMI improved their global strength.展开更多

Objective: The present study examined the impact of grip span on handgrip strength (HGS) in young children using a dynamometer ranging from 2 to 4.5 cm of grip span. Methods: A total of 93 (39 girls and 54 boys) children were recruited from a local kindergarten with the cooperation of their parents. Each participant performed one test trial and then five maximal trials using different grip spans (2.0, 3.0, 3.5, 4.0, and 4.5 cm) in random order and allowing a 1-minute rest between measures. Results: There was a statistically significant difference in HGS depending on which grip span was used, χ<sup>2</sup>(4) = 211.5 (p Conclusion: Our results recommended that the target grip span for measuring maximal HGS in young children is about 4 cm (4 ± 0.5 cm).展开更多

Methods: Handgrip strength (HGS) in kilograms (kgs.) of both hands using handle mechanical dynamometer and counting the repetitions (rep.) of stand and sit on a chair during 30 seconds [the 30 seconds chair-stand test (CST)] were used in 71 elderly (≥65 years old) patients with clinically stable HF and other matched 32 healthy elderly as a control. HF was diagnosed clinically, by plasma B-Type natriuretic peptide (BNP) and by echocardiography. The New York Heart Association (NYHA) functional classification of HF was used to obtain two groups: NYHA class I-II (33 patients), and NYHA class III (38 patients). Results: Showed significant decrease in both HGS and CST score in all HF patients (9.7 ± 4.4 kgs., 8.8 ± 3.1 rep., respectively) compared to controls (77.8 ± 11 kgs., 13.5 ± 1.1 rep., respectively, p Conclusion: Upper and lower limb muscles?strength, assessed by two easy andinexpensive tests (HGS and CST), may reflect clinical severity of HF in elderly patients who cannot usually perform exercise tests. Its prognostic value requires further follow-up studies to verify.展开更多

The objective of the study was to assess reliability of Electronic Push/Pull Dynamometer in the measurement of the knee flexion and extension at 90° and 60° on a new constructed chair. The aims of the author: To assess reliability of Electronic Push/Pull Dynamometer in the measurement of the knee flexion and extension at 90° and 60° on a new constructed chair. Design: A test-retest reliability study. Subjects: One hundred healthy students male and female (mean age, 21y). Methods: Maximum isometric strength of the quadriceps and hamstring muscle groups was measured using the EPPD were recorded at 60° and 90° for 3 trials on 2 occasions. Reliability was assessed with the Intraclass correlation coefficient (ICC), mean and standard deviation (SD) of measurements, and smallest real differences were calculated for the maximum and for the mean and work of the 3 repetitions. Results: Mean strength ranged from 50.44 kg for knee flexion to 55.76 kg for knee extension 50.44 kg to 61.98 kg at 90° hip flexion. Test-retest reliability Intraclass correlation coefficients (ICCs) ranged from 0.85 to 0.99. ICCs for test-retest reliability ranged from 0.780 to 0.998. Conclusions: The results of the reliability study indicate that the EPPD in reliable dynamometer to use in determining lower limb muscle force production. It can be used to measure disease progression and to evaluate changes in knee extension and flexion strength at the individual patient level.展开更多
