The Effectiveness of Whole-Body Vibration and Heat Therapy on the Muscle Strength, Flexibility, and Balance Abilities of Elderly Groups.

Whole-body vibration (WBV) is a novel exercise training measure that promotes the muscle strength, flexibility, and balance abilities of elderly groups. The feasibility and applicability of 20-30 min (lowering a heat pack at 73 °C by wrapping it in multiple layers of towels to 40-43 °C before it touched the skin) thermotherapy are increasingly being demonstrated by applications and clinical trials. Studies show that it increases the flexibility of macules and ligament. However, no studies have examined the interactions between the pre-exercise and post-exercise application of heat therapy (duration a training course). Therefore, this study investigates the effects of WBV and heat therapy on the muscle strength, flexibility, and balance abilities of elderly groups. Eighty middle-age and elderly participants with no regular exercise habits were enrolled in this study. They were randomly assigned to a WBV group, a WBV plus heat therapy group, a heat therapy alone group, and a control group. The WBV groups underwent 5-min, fixed-amplitude (4 mm), thrice-weekly WBV training sessions for 3 consecutive months on a WBV training machine. Participants' balance was measured using the limits of stability (LOS) test on a balance system. The pretest and posttest knee extensor and flexor strength were tested using an isokinetic lower extremity dynamometer. Pretest and posttest flexibility changes were measured using the sit-and-reach test. Significantly larger pretest and posttest differences in flexibility and muscle strength were observed in the WBV and WBV plus heat therapy groups. The addition of heat therapy to WBV resulted in the largest flexibility improvements.

Different weight shift trainings can improve the balance performance of patients with a chronic stroke: A randomized controlled trial.

BACKGROUND: Improving balance ability, increasing walking ability, and reducing the occurrence of falls are important objectives in the rehabilitation of stroke patients. Do the posture balance training and the intervention of lateral wedge insoles to improve of balance function and increase walking ability in patients with a chronic stroke? METHODS: A randomized, controlled trial with concealed allocation, intention-to-treat analysis, and blinded assessors. Participants who had a chronic stroke (onset >6 months) were recruited from the rehabilitation and neurology departments of a hospital in central Taiwan. Subjects were divided into 3 groups: a visual biofeedback balance training group, a lateral wedge group, and a control group; apart from their usual rehabilitation program, and both experimental groups received a 6-week training session program. The primary outcome was the balance computerized adaptive test (balance CAT), and secondary outcome was timed up and go (TUG) test. All subjects were evaluated at the baseline, posttraining (6-week), 1st follow-up (10-week), and 2nd follow-up (18-week). RESULTS: A total of 56 subjects were participated in this study, including 38 males and 18 females. The mean age of the subjects was 59.1 years old, and the mean time was 43.7 months after the onset of the stroke. This study found the interaction in groups and measurement time points reached statistical significance of the balance CAT and TUG test (F = 5.740, P < .001; F = 2.926, P = .011; respectively). In addition, the performance of both the visual biofeedback training and lateral wedge group was superior to that of the control group. CONCLUSION: Six-week visual biofeedback training and intervention of 5° lateral wedge insoles can improve the balance ability of patients with a chronic stroke.

Effect of Two Frequencies of Whole-Body Vibration Training on Balance and Flexibility of the Elderly: A Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to investigate the effects of whole-body vibration training with different frequencies on the balance and flexibility of the healthy elderly. DESIGN: The participants were recruited from hospital volunteers and the community; all of them were healthy subjects, all over 65 years of age. The study involved three randomized groups in a parallel and single-blind design. The main outcome variables included the limits of stability test and the sit and reach test, which were measured at pre-training, Month 1 (Mid-training), Month 3 (Post-training), and Month 6 (Follow-up). RESULTS: A total of 45 subjects, with a mean age of 69.6 ± 3.9 years, were randomly divided into three groups. There was significant interaction in the performance of the limits of stability and sit and reach tests in the different groups at the four different time points (F = 25.218, P < 0.001, F = 12.235, P < 0.001, respectively). There was a significant difference in balance performance between the vibration groups at the frequencies of 20 Hz and 40 Hz and the control group at Month 1, Month 3, and Month 6 (P < 0.001). CONCLUSION: Whole-body vibration training at 20 Hz has significant benefit to the balance and flexibility of the elderly who do not engage in habitual exercise.

Could forearm Kinesio Taping improve strength, force sense, and pain in baseball pitchers with medial epicondylitis?

OBJECTIVE: To determine short-term effects of applied forearm Kinesio Taping (KT) on pain, wrist flexor strength, and force sense for baseball players with medial epicondylitis (ME). DESIGN: Case-control repeated measures study. SETTING: Clinical sports medicine research laboratory in a medical university. PARTICIPANTS: A group of 10 baseball players with ME (ME group) and another group of 17 healthy collegiate athletes (healthy group). INTERVENTION: Three taping conditions were applied in both groups: (1) no taping applied, (2) placebo taping applied (PT), and (3) KT applied. MAIN OUTCOME MEASURES: Three variables were measured including maximal wrist flexor strength, related/absolute force sense errors, and pain scale (pressure pain and pain tolerance) under 3 taping conditions. RESULTS: No significant relationship was found either in maximal wrist flexor strength or in related force sense errors between the 2 groups with taping applied, except absolute force sense errors (P = 0.037). Both the healthy group and the ME group in absolute force sense measurement significantly decreased the errors in PT and KT conditions. Also, the tolerance of pressure pain also improved in both the healthy group and the ME group when performing PT and KT conditions. CONCLUSIONS: Forearm KT may enhance absolute force sense and improve pain condition for both healthy athletes and athletes suffering from ME when placebo and KT applied. However, KT did not result in significant changes in maximal wrist flexor strength for either group.
