Abstract

Abstract: Background: Limited research exists for the effects of neurodynamic treatment techniques. Understanding short term physiological outcomes could help to better understand immediate benefits or harm of treatment. Objectives: To assess the short-term effects of a straight leg raise (SLR) tensioner 'intervention' on pressure pain thresholds (PPT) and vibration thresholds (VT), and establish if additional factors influence outcome in individuals with spinally referred leg pain. Design: Experimental, repeated measures. Methods: Sixty seven participants (mean age (SD) 52.9 (13.3), 33 female) with spinally referred leg pain were divided into 3 sub-groups: somatic referred pain, radicular pain and radiculopathy. Individuals were assessed for central sensitisation (CS) and completed 5 disability and psychosocial questionnaires. PPT and VT were measured pre and post a 3 × 1 min SLR tensioner intervention. Results: No significant differences (p > 0.05) were found between the 3 groups for either outcome measure, or after treatment. Slight improvements in VT were seen in the radiculopathy group after treatment, but were not significant. Only 2 participants were identified with CS. Disability and psychological factors were not significantly different at baseline between the 3 sub-groups, and did not correlate with the outcome measures. Conclusions: No beneficial effects of treatment were found, but the trend for a decrease in VT indicated that even in individuals with radiculopathy, no detrimental changes to nerve function occurred. Psychosocial factors and levels of disability did not influence short term outcome of SLR treatment. Highlights: A straight leg raise tensioner was given to people with spinally referred leg pain. Treatment duration was 3 × 1 min. Pressure pain thresholds and vibration thresholds were the outcome measures. No statistical differences were found before and after treatment or between groups. Psychosocial factors, disability and central sensitisation did not alter outcomes.
