Three primary outcomes were measured: the Maximal Lean Test (also called the Maximal Balance Range), the Maximal
Sideward Reach Test, and the Performance Item of the Canadian Occupational Performance Measure (COPM). Five secondary outcomes were used: the Satisfaction Item of the COPM, the T-shirt Test, Participants’ Impressions of Change, Clinicians’ Impressions of Change, and Spinal Cord Injury Falls Concern Scale. These outcomes were selected on the basis of a study comparing the validity and reliability of each test (Boswell-Ruys et al 2010a, Boswell-Ruys et al 2009) and on the basis of the results of a similar clinical trial (Boswell-Ruys et al 2010b). buy PCI-32765 The Maximal Lean Test assessed participants’ ability to lean as far forwards and backwards as possible without falling and without using the hands for support. The Maximal Sideward Reach Test assessed participants’ ability to reach in a 45° direction to the right while seated unsupported on a physiotherapy bed (Boswell-Ruys et al 2009). The T-shirt Test measured the time taken for participants to don and doff a T-shirt (Boswell-Ruys et al 2009, Chen et al 2003).
The best attempt of two trials was analysed for each outcome. A mean between-group difference equivalent to 20% of mean baseline C59 wnt price data was deemed clinically important for the three outcomes prior to the commencement of the study. The COPM determines participants’ perceptions about treatment effectiveness in relation to self-nominated goals (Law et al 1990). The Performance and Satisfaction
ratings 17-DMAG (Alvespimycin) HCl of the COPM were averaged across the two activities identified as most important to the participant. A mean between-group difference of 2 points was deemed clinically important prior to the commencement of the study as recommended by others (Law et al 2010). Participants’ Impressions of Change were assessed at the end of the 6-week study period by asking both control and experimental participants to rate their global impressions of change in their ability to sit unsupported over the preceding six weeks on a 15-point Likert-style scale, in which –7 indicated ‘a very great deal worse’, 0 indicated ‘no change’, and +7 indicated ‘a very great deal better’ (Barrett et al 2005, Jaeschke et al 1989). Clinicians’ Impressions of Change were assessed with the use of video clips (Harvey et al 2011). Short video clips of participants sitting unsupported were taken at the beginning and end of the 6-week study period. The video clips were then shown to two blinded physiotherapists who were asked to rate their global impressions of change in performance of each participant after viewing the first video clip in relation to the second video clip. The therapists used the same 15-point rating scale used by participants.
