The Effectiveness Of Endurance Exercise On Pain And Function In Adults With Chronic Non-Specific Neck Pain. A Systematic Review.
(2013) The Effectiveness Of Endurance Exercise On Pain And Function In Adults With Chronic Non-Specific Neck Pain. A Systematic Review., no. 92.
Background Chronic non-specific neck pain (NSNP) is a multi-leveled neck condition which results in pain and reduced functional ability. Despite being the most common clinical complaint, the exact pathophysiology and the best treatment option of the condition remain unknown. Due to the wide range of possible factors associated with NSNP, the diagnosis is done through clinical grounds alone. Objectives The primary aim of this systematic review was to evaluate the current evidence-base regarding the effectiveness of endurance exercise to reduce pain levels and improve function in adults with chronic NSNP. Search Strategy Using pre-selected keywords, the databases Pubmed, Scopus Ebsco, Journal OVIDSP, Scopus and Google Scholar were searched to identify relevant articles in August of 2013. Selection Criteria All randomized controlled trials that evaluated the effects of endurance exercise on either pain or function of individuals with chronic NSNP and that met the pre-determined inclusion criteria were accepted. Data collection and analysis The methodological quality of the selected articles were evaluated using the Physiotherapy Evidence Database (PEDro) and graded as being either low, average, good, or excellent quality. Main results Eight studies were selected and graded as being of either average to good quality. Seven of the eight included studies found that focusing endurance exercise on either the deep neck flexors of the neck, or the general neck musculature were effective at improving pain and restoring function. Endurance exercise was not found to have greater effect on pain and function when compared to other validated treatment techniques. Lastly, one study of average quality found that endurance exercise was unable to improve pain and function in elderly patients with long- standing chronic NSNP. Conclusions Based on the current systematic review, moderate to high quality evidence indicates that endurance exercise may be of benefit in relieving pain and returning function in adults with chronic NSNP. In addition, low quality evidence indicates endurance exercise will not make improvements in the elderly population with longer periods of chronic NSNP.
