Comparison of proprioceptive functions between computerized proprioception facilitation exercise and closed kinetic chain exercise in patients with knee osteoarthritis.

AIM: The aim of this study was to compare proprioceptive function between computerized proprioception facilitation exercise (CPFE) and closed kinetic chain exercise (CKCE) for knee osteoarthritis. DESIGN: Randomized-controlled. SETTING: Kinesiology laboratory. PATIENTS: Eighty-one patients with bilateral knee osteoarthritis were randomly assigned to CPFE, CKCE, and control groups. INTERVENTION: Both exercise groups underwent an 8-week program of three sessions per week. The control group received no training. The CPFE program included a 20-min computer game to be played by the trained foot of the subject. CKCE included 10 sets of 10 repetitions of repeated knee extension and flexion with resistance of 10-25% of body weight. MAIN OUTCOME MEASURES: Absolute reposition error, functional score, walking speed, and knee muscle strength were assessed with an electrogoniometer, the physical function subscale of Western Ontario and McMaster Osteoarthritis Index, a CASIO stopwatch, and a Cybex 6000 dynamometer before and after the 8-week period. RESULTS: The results of this study showed that both CPFE and CKCE were effective in improving joint position sense, functional score, walking speed, and muscle strength. Furthermore, CKCE showed greater effect in increasing knee extensor torque in patients with knee osteoarthritis. CONCLUSION: Clinical effects of CPFE were the same as those of CKCE except for knee extensor torque. The increase in knee extensor torque in CPFE patients was not as great as that seen in CKCE patients.

Effects of repetitive shortwave diathermy for reducing synovitis in patients with knee osteoarthritis: an ultrasonographic study.

BACKGROUND AND PURPOSE: Shortwave (SW) diathermy can be used to improve vascular circulation and reduce inflammation and pain for patients with osteoarthritis. However, reduction in synovial inflammation has never been explored. The purpose of this study was to investigate whether repetitive SW diathermy, using ultrasonographic examination, could reduce synovitis in patients with knee osteoarthritis. SUBJECTS AND METHODS: Thirty subjects with 44 osteoarthritic knees participated in this study. Eleven subjects received SW, and 10 subjects received SW and nonsteroidal anti-inflammatory drugs. Nine subjects received no treatment and served as a control group. Synovial sac thickness superior, medial, and lateral to the patella was measured using ultrasonography. The sum of these 3 measurements was taken as the total synovial sac thickness. Subjects in the treatment groups underwent ultrasonographic examination before and after 10, 20, and 30 treatments, whereas control subjects underwent ultrasonographic examination before the experiment and then once every 2 or 3 weeks for a total of 3 follow-up measurements. RESULTS: After 10 SW diathermy treatments, the total synovial sac thickness in both treatment groups was significantly less than the initial thickness, and the synovial sac continued to become significantly thinner with 20 sessions of treatment. These observations were not made in the control subjects. DISCUSSION AND CONCLUSION: The results indicate that SW diathermy in patients with knee osteoarthritis can significantly reduce both synovial thickness and knee pain. Such reductions of synovial sac thickness and pain index continue over treatment sessions.

Effects of age and sex on the results of an ankle plantar-flexor manual muscle test.

BACKGROUND AND PURPOSE: The ability to perform 20 or more one-leg heel-rises is considered a "normal" grade for muscle strength (force-generating capacity of muscle) of the ankle plantar flexors, regardless of age and sex. Because muscle strength is closely related to age and sex, the "normal" test criterion was re-evaluated in different groups categorized by age and sex. SUBJECTS AND METHODS: One hundred eighty sedentary volunteers (21-80 years of age) without lower-limb lesions performed as many repetitions of one-leg heel-rise as possible. Lunsford and Perry criteria were used to determine completion of the test. RESULTS: The age and sex of the participants influenced the maximal repetitions of heel-rise, and the repetitions decreased with age and in female subjects. DISCUSSION AND CONCLUSION: The muscle strength of the ankle plantar flexors, as measured by manual muscle testing, varied with age and sex. Clinicians should consider the variances of age and sex when they perform manual muscle testing of the ankle plantar flexors.
