Functional status and/or HRQOL following exercise training for patients with IC.

Authors & Year (* sample size; interval)	Questionnaires	Type of training	Outcome
** Regensteiner et al 199676 (n = 21; 24 wks)	a WIQ	supervised exercise strength training non-exercise	supervised group improved WIQ & SF-20 scores, specifically the physical domains
Patterson et al 1997120 (n = 38; 24 wks)	1 SF-36	supervised exercise home-based exercise	improvement in physical function, pain & physical component scores for both groups
** Regensteiner et al 199779 (n = 20; 12 wks)	WIQ	supervised exercise unsupervised exercise	supervised group improved WIQ walking distance & speed scores & SF-20 physical functioning scores
Wullink et al 200177 (n = 24; 24 wks)	WIQ	† unsupervised exercise	pain, distance, speed & stair climbing domains improved but not significant
Nicolai et al 200978 (n = 91; 12 wks)	SF-36 2 EuroQOL WIQ	supervised exercise	all WIQ domains improved; largest effect for SF-36 was pain & physical functioning; EuroQOL index improved
Nicolai et al 201075 (n = 252; 1 year)	SF-36 WIQ	supervised exercise †† supervised exercise unsupervised	physical summary score of SF-36 improved, no improvement in mental summary score; total WIQ scores improved

^*Indicates final sample size for claudicants & final outcome assessment time point.

^**Also employed SF-20 which was not discussed in this review.

^†Employed additional coaching in the home-based setting but did not directly supervise exercise.

^††Provided an accelerometer to patients for additional feedback.

¹SF-36 = Short Form 36-item questionnaire;

²EuroQOL = European Quality of Life questionnaire

^aWIQ = Walking Impairment Questionnaire
