Effect of Sling Rehabilitation Exercises with Vibration Balls on the Upper Limb Muscle Activity for disabled people

The purpose of the present study is to verify the effectiveness of a muscle activity by applying the complex functional exercise methods and active rehabilitation methods of sling exercises in accordance with the provision of vibration for people with myelopathy. Study subjects were 16 men in their 40s and 50s with lower limb disabilities. They were randomly divided into a sling exercise group (SG n=4), a sling with low frequency vibration group (SLVG n=4), a sling with mid-frequency vibration group (SMVG n=4), and a sling with high frequency group (SHVG n=4). The anterior deltoid (AD), the posterior deltoid (PD), the pectoralis major (PM), the upper trapezius (UT), the latissimus dorsi (LD), the triceps (TC), the biceps (BC), and the multifidus (MF) were measured to compare and analyze muscle activity. One-way ANOVA was conducted to compare the recovery effects by using SPSS 18.0 Korea. The statistical significance was accepted at p<0.05. Our results showed that the low intensity vibration (30Hz) was the effective stimuli for open kinetic chain exercises, while vibration stimuli of an mid intensity (50Hz) were the effective vibration for closed kinetic chain.
