The results revealed that despite significant strength gains , many studies failed to show a significant improvement in walking capacity .
Strength testing and strengthening exercises were prioritized for the knee extensors and flexors , despite their relatively minor role in human walking .
Strengthening exercises performed in the neurologic population are not specific to the main muscle groups responsible for the power generation required for walking .
There is a predisposition for strength testing and strengthening exercises to focus on the knee flexors and extensors despite their relatively minor role during walking .
The aim of this systematic review was to investigate the task specificity of strength training programs for walking in neurologic rehabilitation .
The effects of home-based resistance exercise on balance, power, and mobility in adults with multiple sclerosis.
OBJECTIVE To examine the effects of an 8-week home-based resistance exercise program on balance , power , and mobility in adults with multiple sclerosis . DESIGN Experimental group design . SETTING General community . PARTICIPANTS Twenty-nine women ( age , 50.3+/-8.5 y ) and 8 men ( age , 51.1+/-7.1 y ) were stratified by disability level and age and were r and omized into exercise ( n=19 ) and control ( n=17 ) groups . INTERVENTION The exercise group had lower-extremity resistance training 3 times a week . The control group maintained current level of physical activity . Main outcome measures Primary outcome measures included balance , as measured by anteroposterior sway , mediolateral sway , and sway velocity using the AccuSway(PLUS ) force platform ; mobility as assessed with the Up and Go test ; and leg power as assessed with the Leg Extensor Power Rig . RESULTS Leg extensor power improved significantly in the exercise group ( pretest , 3.19+/-1.36 W/kg ; posttest , 3.95+/-1.23 W/kg ; P=.004 ) , although measures of balance and mobility did not change . CONCLUSIONS The home-based resistance program was well tolerated by participants and offered a practical means to improve leg extensor power in a short period of time
