Abstract

ObjectiveTo assess the effects of adding a neurodynamic intervention into a multimodal management approach in individuals with multiple sclerosis (MS) with upper extremity pain symptoms. DesignRandomized clinical trial. SettingTertiary hospital center. ParticipantsThirty-two individuals with MS were randomly assigned to multimodal usual care alone (n=16) or multimodal usual care plus neurodynamic intervention (n=16). InterventionsBoth groups received 5 sessions of multimodal usual care of 30minutes duration, twice per week. Subjects allocated to the neurodynamic group also received bilateral neurodynamic slider interventions targeting the upper extremity nerve trunks. Outcome measuresPressure pain thresholds (PPTs) at the radial, median and ulnar nerve trunks, second metacarpal and tibialis anterior, pain intensity in the upper extremity (NPRS, 0–10), light touch detection threshold (von Frey hairs) and manual dexterity (nine-hole peg test) were assessed before and after the intervention. ResultsSubjects receiving the neurodynamic interventions experienced larger improvements in PPTs at all locations (moderate effect size, between-groups differences from 89.5 to 186.5kPa), a higher decrease in pain intensity at rest (large effect, difference 1.7, 95%CI 0.4 to 3.0) and improvements in sensitivity to light touch (moderate effect, difference −0.7, 95%CI −1.3 to −0.1) and in manual dexterity (large effect, difference 7.7, 95%CI 4.0 to 11.4seconds) than those that did not receive the neurodynamic intervention. ConclusionsThe inclusion of neural mobilization into a multimodal management approach resulted in reduction of pressure sensitivity, greater reduction in pain and improvement in sensitivity to light touch and manual dexterity in MS. Further studies are necessary to confirm these findings at longer term follow-ups. (ClinicalTrials.gov: NCT03595631)
