While neck strength training has been shown to be effective in improving neck muscle strength and reducing neck pain HRQoL among patients with neck pain has been reported as an outcome in only two short-term exercise intervention studies. Thus reports on the influence of a longterm neck strength training intervention on HRQoL among patients with chronic neck pain have been lacking. This study reports the effect of one-year neck strength training on HRQoL in females with chronic neck pain. Methods One hundred eighty female office workers 25 to 53 years of age with chronic neck pain were randomized to a strength training group STG n 60 endurance training group ETG n 60 or control group CG n 60 . The STG performed high-intensity isometric neck strengthening exercises with an elastic band while the ETG performed lighter dynamic neck muscle training. The CG received a single session of guidance on stretching exercises. HRQoL was assessed using the generic 15D questionnaire at baseline and after 12 months. Statistical comparisons among the groups were performed using bootstrap-type analysis of covariance ANCOVA with baseline values as covariates. Effect sizes were calculated using the Cohen method for paired samples. Results Training led to statistically significant improvement in the 15D total scores for both training groups whereas no changes occurred for the control group P between groups . The STG improved .
