OBJECTIVE: The purpose of this study is to determine strength changes in the knee measured throughout full range of motion following Instrument Assisted Soft Tissue Mobilization. METHODS: 13 subjects underwent pre-screening for existing soft tissue lesions. Subjects performed multiple angle isometric strength testing at the knee (15°, 45°, 60°, 90°, 115° of knee flexion) prior to beginning a 4-week resistance training protocol. Subjects performed knee extension/flexion exercises (2x15) 3 times a week for 4 weeks. Following the training period, subjects were post tested using the same protocol as used in the pre-test. DATA ANALYSIS: A paired sample t-test was used to determine the difference in isometric peak torque between the control knee and treatment knee. A (2x5) ANOVA was used to compare each angle of isometric force for both knee flexion and extension in the control knee vs. the treatment knee. RESULTS: Improvements in strength were significant for knee extension in both legs following the 4-week resistance training protocol. No difference was observed between the two legs at each of the 5 angles examined. No significant change in range of motion was observed. CONCLUSION: Instrument Assisted Soft Mobilization has no effect on ROM and strength changes for healthy subjects, who have no prior history of knee or thigh injury. Its success is documented for therapeutic purposes, but more research is needed in regards to its use for a healthy population. |
