The effectiveness of slider and tensioner neural mobilization techniques in the management of upper quadrant pain: A systematic review of randomized controlled trials.

Background: Little attention has been given to support the use of slider and tensioner neural mobilization (NM) techniques for upper quadrant pain (UQP). The purpose of this study was to systematically review the effectiveness of these techniques in patients with UQP.

Method: The PubMed, Cochrane Library and EBSCOhost were searched without chronological restriction to identify randomized clinical trials (RCTs) that assessed pain changes following NM in the upper quadrant. Two researchers independently performed screening, full-text assessment, data extraction and risk of bias assessment of the studies.

Results: A total of 974 articles were identified, of which 25 were included in this systematic review. The score for methodological quality of studies included was between 5 and 10 with a mean score of 7.96 points. Results demonstrated that slider and tensioner NM techniques are considered beneficial in pain reduction of UQP in certain musculoskeletal conditions including carpal tunnel syndrome and cervical radiculopathy. Regarding other conditions such as subacromial impingement syndrome, lateral elbow tendinopathy and cubital tunnel syndrome, due to conflicting findings, various methodological limitations and/or inadequate information, the available evidence remains uncertain. Furthermore, slider NM was found to be more effective in acute conditions compared to tensioner NM that seems to provide further analgesic effect in chronic UQP.

Conclusions: This systematic review revealed that NM slider and tensioner techniques can be used as analgesic modalities for managing UQP resulting from cervical radiculopathy and carpal tunnel. There remain unanswered questions concerning other conditions, and, therefore, further well-designed RCTs are needed to examine the analgesic response of NM techniques in UQP.
