Predicting Response to Exercise in Patients with Neck Pain
I have attached an article by Keating et al titled “Predicting short-term response and non-response to neck strengthening exercise for chronic neck pain” from the Journal of Whiplash and Associated Disorders. The authors examined the predictive validity of patient age, sex, duration of symptoms, compensation status, NDI scores, and cervical spine ROM for determining which individuals are likely to respond to a tailored exercise program. The reference standard for a successful outcome was an improvement in the NDI of at least 14 points (twice the MCID). In the first sample (n= 122) a NDI cut off 30 accurately predicted 70% of patients who responded to the exercise intervention (OR 5.56, 95% CI 2.2-13.9). Those with scores > 30 were more likely to meet the 14 point cut off. However, when tested on a second sample (n = 214) the predictive accuracy of the NDI diminished. The authors conclusion- collect more possible predictor variables to enhance the model (Ie.. CPR).
