Outcomes
disability, NDI
The outcome measures were reported using questionnaires on Linköping University’s website, Survey and Reports, at baseline and 3 and 15 months after baseline (ie, 12 months after the intervention ended). Ratings on a VAS and Patient-Specific Functional Scale (PSFS) were collected by the test leader. The participants formulated 3 specific activity goals to improve daily activities at work, during leisure time, and during physical exercise using the PSFS. The goals were specified for time and designed to be achievable during the 3-month rehabilitation program (eg, computer work for 20 minutes, 5 days a week).The null hypothesis was that the clinically important reduction in the NDI in the NSE group would be at least 7 points (percent scale) better than the reduction in the NSEIT group. The noninferiority margin was based on the recommendation for a minimal clinically important change in NDI (7%) [The primary outcome was the NDI, which is considered a reliable and valid measurement of disability due to neck pain [
