“…A preoperative SCT was performed in seven studies (Pate et al, 1996;Holden et al, 1992;Dong et al, 2017;Refai et al, 2014;Nikolic et al, 2007;Toker et al, 2007;Brunelli et al, 2001), in which different SCT protocols were used. Patients were asked 1) to climb the maximum number of steps at a pace of their own choice (Pate et al, 1996;Holden et al, 1992;Refai et al, 2014;Nikolic et al, 2007;Brunelli et al, 2001), 2) to climb five stairs with 20 steps as fast as they could without stopping to rest (Dong et al, 2017), or 3) to do their best during 2 stair-climbing exercises in which each flight of stairs was composed of 20 steps and climbing time was recorded (Toker et al, 2007). There were also differences between studies concerning test duration, step height, and number of steps.…”
