Résumé : Objective
To develop and validate a self-reported questionnaire assessing the barriers to physical activity (PA) among stroke survivors.
Ambulatory stroke care.
A total of one hundred and forty-six (N=146) individuals were included in this study. In stage 1, community-living stroke survivors (n=37; 13 women) with low-moderate disability (modified Rankin Score 0-3, stroke >3mo) were included. In stage 2, participants (n=109; 40 women) with same characteristics were included. Nine professionals experienced in PA for poststroke patients formed an expert panel.
In stage 1, semistructured interviews identified perceived barriers to PA, which were then selected by the expert panel and grouped on a Barriers to Physical Activity After Stroke (BAPAS) scale. In stage 2, stroke participants completed a personal information questionnaire and the BAPAS scale.
Main Outcome Measures
An item selection process with factor analysis was carried out. The suitability of the data set was analyzed using the Kaiser-Meyer-Olkin coefficient, internal consistency was evaluated by Cronbach α, and concurrent validity was assessed with Spearman correlation coefficients between the BAPAS scale and the modified Rankin Scale. Test-retest repeatability was estimated using 2-way random effects intraclass correlation coefficient model 2,1 at 4-6 day follow-up (n=21).
Factor analysis supported a 14-item BAPAS that explained 62% of total variance (Kaiser-Meyer-Olkin=0.82) and total score calculated higher than 70 (higher scores for higher barriers). Cronbach α was 0.86, Spearman correlation with the modified Rankin Scale was r=0.65 (P<.001 and test-retest intraclass correlation coefficient was ci the bapas scores were higher in patients with greater disabilities those a longer time since stroke event> Conclusion
We developed and validated the BAPAS scale to assess barriers to PA in stroke survivors with low-moderate disability with promising psychometric properties.

To assess the safety and acute effects of a procedure using perceived exertion during a prior submaximal concentric (CON) test to individualize eccentric (ECC) cycling exercise intensity.
Prospective, monocentric open study.
Technological investigation platform at a physical medicine and rehabilitation department in a university hospital.
Healthy subjects (N=18; 15 men, 3 women) aged between 22 and 37 years.
The subjects performed 3 cycling exercises: (1) incremental CON test to determine the comfortable pedaling power (CPP) corresponding to a Borg scale rating of 12 (rate of perceived exertion); (2) steady-state CON exercise at the CPP workload to determine the corresponding plantar pressure; and (3) steady-state ECC exercise with an imposed resistance corresponding to the CPP plantar pressure.
Main Outcome Measures
Rate of perceived exertion on Borg scale, oxygen uptake (VO2Max), heart rate, cardiac output, and stroke volume using inert gas rebreathing techniques were measured during steady-state CON and ECC exercises. Muscle soreness was rated on a visual analog scale immediately, 24, and 48 hours after the tests.
No adverse effects were reported. VO2Max was about 5 times the resting value during CON exercise, while it was twice that during ECC exercise. Cardiac output was lower during ECC exercise (P<.05 this moderate increase of cardiac output was exclusively linked to a greater in stroke volume during ecc exercise than con> Conclusions
Moderate-intensity ECC cycling exercise tailored according to perceived exertion during a prior CON test is well tolerated. It corresponds to a limited muscular use of oxygen and to an isolated increase in stroke volume. It appears to be a feasible procedure for preconditioning before ECC training.
