- Objective: To compare short-and long-term changes in neck muscle endurance, electromyography measures of neck muscle activation and fatigue and ratings of fatigue and pain after neck-specific training or physical activity in people with cervical radiculopathy. Design: Randomized clinical trial. Subjects/patients: Seventy-five patients with cervical radiculopathy. Methods: Patients underwent neck-specific training in combination with a cognitive behavioural approach or prescribed physical activity over a period of 14 weeks. Immediately after the intervention and 12 months later, surface electromyography was recorded from neck flexor and extensor muscles during neck endurance tests. Time to task failure, amplitude and median frequency of the electromyography signal, and subjective fatigue and pain ratings were analysed in 50 patients who completed at least one follow-up. Results: A significant increase in neck flexor endurance time was observed for both groups at 14 weeks compared with baseline and this was maintained at the 12-month follow-up (pamp;lt;0.005). No change was identified for the slope of the median frequency. For the neck-specific training group, splenius capitis was less active during neck flexion at both follow-ups (pamp;lt;0.01), indicating reduced muscle co-activation. Conclusion: Both specific and general exercise increased neck flexor endurance, but neck-specific training only reduced co-activation of antagonist muscles during sustained neck flexion.

- Objective: To explore whether neck-specific exercise, with or without a behavioural approach, has benefits after 1 and 2 years compared with prescribed physical activity regarding pain, self-rated functioning/disability, and self-efficacy in management of chronic whiplash. Design: Follow-up of a randomized, assessor blinded, clinical trial. Patients: A total of 216 volunteers with chronic whiplash associated disorders, grades 2 or 3. Methods: Participants were randomized to 1 of 3 exercise interventions: neck-specific exercise with or without a behavioural approach, or physical activity prescription. Self-rated pain (visual analogue scale), disability/functioning (Neck Disability Index/Patient Specific Functional Scale) and self-efficacy (Self-Efficacy Scale) were evaluated after 1 and 2 years. Results: Both neck-specific exercise groups maintained more improvement regarding disability/functioning than the prescribed physical activity group at both time-points (p <= 0.02). At 1 year, 61% of subjects in the neck-specific group reported at least 50% pain reduction, compared with 26% of those in the physical activity prescription group (p < 0.001), but at 2 years the difference was not significant. Conclusion: After 1-2 years, participants with chronic whiplash who were randomized to neck-specific exercise, with or without a behavioural approach, remained more improved than participants who were prescribed general physical activity.
