Conclusion Although data are limited , there is a strong significant relationship between plantar flexor muscle strength and treadmill walking ability .
Background and Objective Exercise is a widely accepted treatment known to improve walking ability in persons with peripheral arterial disease ( PAD ) ; however , it has not been confirmed as to whether exercise improves fitness and performance-based function and , consequently , performance of activities of daily living ( ADL ) .
This systematic review aims to identify whether any mode of structured exercise improves physical fitness or performance-based tests of function and whether improvement in walking ability is related to an improvement in these outcomes .
Data Sources and Study Selection Eligible studies included r and omized controlled trials ( RCTs ) using an exercise intervention for the treatment of intermittent claudication with fitness ( including the 6-min walk ( 6MW ) , aerobic capacity , shuttle and muscle strength ) tests and performance-based tests of function as the outcomes .
Hospital vs Home-Based Exercise Rehabilitation for Patients with Peripheral Arterial Occlusive Disease
Supervised , hospital-based exercise rehabilitation programs are effective for improving functional status for patients with claudication due to peripheral arterial occlusive disease . However , it has been suggested that unsupervised , home-based exercise programs , which have been relatively little evaluated , would be equally efficacious as compared with hospital-based programs . The authors tested the hypothesis that a hospital-based exercise rehabilitation program would improve treadmill exercise perfor mance more than a home-based program . Of 20 consecutively enrolled patients with claudication , 10 were r and omly placed into a supervised , hospital-based program and 10 into an unsupervised , home-based program for a three-month period .  Exercise perfor mance was evaluated by treadmill testing using a grade d protocol . In addition , func tional status was evaluated by the Walking Impairment Question naire ( WIQ ) and the Medical Outcomes Study SF-20 question naire ( MOS ) . Patients in the hospital-based program were treated with treadmill walking three times a week for one hour/visit . Patients in the home-based program were instructed to walk at least three times a week and were contacted weekly to provide encouragement and to record compliance with ( continued on next page ) the program . Patients in the hospital-based group improved peak walking time by 137 % , pain-free walking time by 150 % , and peak oxygen consumption by 19 % ( all P<0.05 ) . Patients reported an improved walking distance and speed according to WIQ data ( both P<0.05 ) . In addition , the MOS physical functioning score in the hospital-based group improved by 20 percentage points ( P<0.05 ) . In contrast , patients in the home-based program did not improve exercise performance measured on the treadmill . Improvement in the ability to walk on the treadmill was greater in the hospital-based than the home- based program ( P<0.05 ) . The ability to walk distances was the only question naire measure that improved in persons who received the home-based program ( P<0.05 ) . Preliminary results suggest that a supervised , hospital-based program is more effective for improving treadmill exercise performance than an unsupervised , home-based program
