Percentage of participants with at least 50% reduction in arm pain/paraesthesia bothersomeness and change of percentage of participants with no minimum arm pain after 1 year. NSE = Neck-specific exercise, NSEB = Neck-specific exercise with a behavioural approach, PPA = Prescription of Physical Activity *p < 0.05, **p < 0.01. Bars represent standard errors. Number of participants/total with>50% improvement of current pain: NSE 18/30, NSEB 17/30, PPA 7/24, worst pain: NSE 17/31, NSEB 13/37, PPA 4/27, paresthesia NSE 19/32, NSEB 20/41, PPA 10/35. No minimum arm pain indicates <3 mm VAS. Change no minimum arm pain indicates that 16% more participants in the NSE group and 21% in the NSEB group, and 18% fewer participants reported no minimum arm pain as compared with baseline.
