Table 2 Within the groups: pain intensity (Numeric rating scale, NRS), function measured by Neck disability index (NDI), range of motion in the neck, and strength in the neck and shoulders at baseline after 4 to 6 months of training and 12 months of training

From: Evaluation of pain and function after two home exercise programs in a clinical trial on women with chronic neck pain - with special emphasises on completers and responders
