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 .
Effects of a long-term exercise program on lower limb mobility, physiological responses, walking performance, and physical activity levels in patients with peripheral arterial disease.
OBJECTIVE The purpose of the study was to examine the effects of a 12-month exercise program on lower limb mobility ( temporal-spatial gait parameters and gait kinematics ) , walking performance , peak physiological responses , and physical activity levels in individuals with symptoms of intermittent claudication due to peripheral arterial disease ( PAD-IC ) . METHODS Participants ( n = 21 ) with an appropriate history of PAD-IC , ankle-brachial pressure index ( ABI ) < 0.9 in at least one leg and a positive Edinburgh claudication question naire response were prospect ively recruited . Participants were r and omly allocated to either a control PAD-IC group ( CPAD-IC )  ( n = 11 ) that received st and ard medical therapy and a treatment PAD-IC group ( TPAD-IC ) ( n = 10 ) , which also took part in a 12-month supervised exercise program . A further group of participants ( n = 11 ) free of PAD ( ABI > 0.9 ) and who were non-regular exercisers were recruited from the community to act as age and mass matched controls ( CON ) . Lower limb mobility was determined via two-dimensional video motion analysis . A grade d treadmill test was used to assess walking performance and peak physiological responses to exercise . Physical activity levels were measured via a 7-day pedometer recording . Differences between groups were analyzed via repeated measures analysis of variance ( ANOVA ) . RESULTS The 12-month supervised exercise program had no significant effect on lower limb mobility , peak physiological responses , or physical activity levels in TPAD-IC compared with CPAD-IC participants . However , the TPAD-IC participants demonstrated significantly greater walking performance ( 171 % improvement in pain free walking time and 120 % improvement in maximal walking time compared with baseline ) . CONCLUSION The results of this study confirm that a 12-month supervised exercise program will result in improved walking performance , but does not have an impact on lower limb mobility , peak physiological responses , or physical activity levels of PAD-IC patients
