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 .
Reporting of noninferiority and equivalence randomized trials: an extension of the CONSORT statement.
The CONSORT ( Consoli date d St and ards of Reporting Trials ) Statement , including a checklist and a flow diagram , was developed to help authors improve their reporting of r and omized controlled trials . Its primary focus was on individually r and omized trials with 2 parallel groups that assess the possible superiority of one treatment compared with another but is now being extended to other trial design s. Noninferiority and equivalence trials have method ological features that differ from superiority trials and present particular difficulties in design , conduct , analysis , and interpretation . Although the rationale for such trials occurs frequently , those design ed and described specifically as noninferiority or equivalence trials appear less commonly in the medical literature . The quality of reporting of those that are published is often inadequate . In this article , we present an adapted CONSORT checklist  for reporting noninferiority and equivalence trials and provide illustrative examples and explanations for those items amended from the original CONSORT checklist . The intent is to improve reporting of noninferiority and equivalence trials , enabling readers to assess the validity of their results and conclusions
