The HBET group did not show improvement in MWD/T compared with the WA group ( SMD 0.30 , 95 % CI -0.45 to 1.05 ; P = 0.43 ; moderate- quality evidence ) .Compared with HBET , SET was more beneficial for PFWD/T but had no effect on quality of life parameters nor on self-reported functional impairment .
Compared with WA , SET was more beneficial for PFWD/T and self-reported functional impairment , as well as for some quality of life parameters ( e.g. , physical functioning , pain , and physical component summary after 12 months ) , and HBET had no effect .
Data show no obvious effects on mortality rates .
Evidence of moderate and high quality shows that SET provides an important benefit for treadmill-measured walking distance ( MWD and PFWD ) compared with HBET and WA , respectively .
Although its clinical relevance has not been definitively demonstrated , this benefit translates to increased MWD of 120 and 210 meters after three months in SET groups .
These increased walking distances are likely to have a positive impact on the lives of patients with IC .
Data provide no clear evidence of a difference between HBET and WA .
Trials show no clear differences in quality of life parameters nor in self-reported functional impairment between SET and HBET .
BACKGROUND Although supervised exercise therapy ( SET ) provides significant symptomatic benefit for patients with intermittent claudication ( IC ) , it remains an underutilized tool .
Widespread implementation of SET is restricted by lack of facilities and funding .
Structured home-based exercise therapy ( HBET ) with an observation component ( e.g. , exercise logbooks , pedometers ) and just walking advice ( WA ) are alternatives to SET .
This is the second up date of a review first published in 2006 .
OBJECTIVES The primary objective was to provide an accurate overview of studies evaluating effects of SET programs , HBET programs , and WA on maximal treadmill walking distance or time ( MWD/T ) for patients with IC .
Secondary objectives were to evaluate effects of SET , HBET , and WA on pain-free treadmill walking distance or time ( PFWD/T ) , quality of life , and self-reported functional impairment .
Experimental Model of Pain-Free Treadmill Training in Patients with Claudication
Mika P , Spodaryk K , Cencora A , Unnithan VB , Mika A : Experimental model of pain-free treadmill training in patients with claudication . Am J Phys Med Rehabil 2005;84:756–762 . Objective : Treadmill training in claudication is often based on walking exercise to a pain threshold or longer to the maximum muscle pain of the lower limbs . This kind of exercise may cause an inflammatory response . The purpose of this study was to determine whether pain-free treadmill training using walking exercise to 85 % of the distance to onset of claudication pain can significantly improve pain-free walking distance in patients with intermittent claudication and to evaluate whether this kind of program may induce an inflammatory response leading to the progression of atherosclerosis . Design : A total of 98 patients aged 50–70 yrs with stable intermittent claudication were r and omized into a supervised treadmill training program or a comparison group . Patients in the treatment group participated in 12 wks of supervised treadmill training . We examined the effects of 12 wks of pain-free treadmill training on pain-free walking distance , total leukocyte count , neutrophil count , and microalbuminuria in patients with claudication . Results : A total of 80 participants completed the program .  Exercise rehabilitation increased the time to onset of claudication pain by 119.2 % , from 87.4 ± 38 m to 191.6 ± 94.8 m ( P < 0.001 ) . There was no increase in total leukocyte count , neutrophil count , or microalbuminuria after 12 wks of treadmill exercise ( P > 0.05 ) Conclusion : A pain-free training program can be used in the treatment of claudication as a low-risk program , increasing walking ability without potential harmful effects of ischemia – reperfusion injury
