Investigating the Effect of Rebound Therapy Practical Program on the Explosive Power of Bottom Extremity in Hearing-Impaired Students

Abstract

Objective: The purpose of this study was to examine the effect of rebound therapy practical program on explosive power of bottom extremity in hearing-impaired students. Methods: 32 hearing-impaired female students voluntarily participated in this study and they were randomly divided into two experimental and control groups. Explosive power of bottom extremityin pretest and post-test was measured using Sargent Jump Test. Experimental group performed rebound practical program for 8 weeks and 3 sessions per week for 30 to 45 minutes. SPSS version 18 software was used for statistical analysis. Results: The mean and standard deviation of age (16.22 +/- 1.641year), weight (52.88 +/- 10.070 Kg) and height (158.09 +/- 7.239cm) of subjects were measured. The mean of Sargent jump test record in pre-test were 2517.28 and 3474.65 in the two groups and these values got to 2167.8 and 2910.08 in post-test. The findings suggested positive effect of rebound therapy practical program on explosive power of bottom organ (p= 0.839) in the hearing-impaired students. Conclusion: According to the obtained results, rebound therapy practical program is effective in rehabilitation of hearing-impaired students and this method can be used in physical rehabilitation in hearing-impaired children and teenagers.
