Exercise programmes were of significant benefit compared with placebo or usual care in improving walking time and distance in selected patients with leg pain from IC
BACKGROUND Exercise programmes are a relatively inexpensive , low-risk option compared with other more invasive therapies for leg pain on walking ( intermittent claudication ( IC ) ) .
OBJECTIVES To determine the effects of exercise programmes on IC , particularly in respect of reduction of symptoms on walking and improvement in quality of life .
Strength training increases walking tolerance in intermittent claudication patients: randomized trial.
OBJECTIVE To analyze the effects of strength training ( ST ) in walking capacity in patients with intermittent claudication ( IC ) compared with walking training ( WT ) effects . METHODS Thirty patients with IC were r and omized into ST and WT . Both groups trained twice a week for 12 weeks at the same rate of perceived exertion . ST consisted of three sets of 10 repetitions of whole body exercises . WT consisted of 15 bouts of 2-minute walking . Before and after the training program walking capacity , peak VO(2 ) , VO(2 ) at the first stage of treadmill test , ankle brachial index , ischemic window , and knee extension strength were measured . RESULTS ST improved initial claudication distance ( 358 + /- 224 vs 504 + /- 276 meters ; P < .01 ) , total walking distance ( 618 + /- 282 to 775 + /- 334 meters ; P < .01 ) , VO(2 ) at the first stage of treadmill test ( 9.7 + /- 2.6 vs 8.1 + /- 1.7 mL.kg(-1).minute ; P < .01 ) , ischemic window ( 0.81 + /- 1.16 vs 0.43 + /- 0.47 mm Hg minute meters(-1 ) ; P = .04 ) , and knee extension strength ( 19 + /- 9 vs 21 + /- 8 kg and 21 + /- 9 vs 23 + /- 9 ; P < .01 ) . Strength increases correlated with the increase in initial claudication distance ( r = 0.64 ; P = .01 ) and with the decrease in VO(2 ) measured at the first stage of the treadmill test ( r = -0.52 ; P = .04 and r = -0.55 ; P = .03 ) . Adaptations following ST were similar to the ones observed after WT ; however , patients reported lower pain during ST than WT ( P < .01 ) . CONCLUSION ST improves functional limitation similarly to WT but it produces lower pain , suggesting that this type of exercise could be useful and should be considered in patients with IC
