Abstract

|
|
Purpose: The purpose of this study was to investigate the effects of backrest angle on lower extremity muscle strength in adult.
Method: This research results are based on 10 healthy adults. 10 degree difference in pelvic angle does not effect the cross-connection of the Hamstring muscles, and created 3 types of rest with 20 degree differences each at 95, 115, and 135 degree angles.
Result: significantly difference in contractibility muscle strength in accordance to the 3 rake angle.
Conclusion: After putting together all these results, since both the expansibility muscle strength and contractibility muscle strength of the knee showed to be effected as the backrest angle changed during isokinetic muscle strength assessment, further research should be conducted if similar research results as this study can be acquired at various angles.
