Effect of Aerobic Exercise Programme on Neuropathic Pain and Quality of Life in Person with Paraplegia: Study Protocol for a Randomized Controlled Trial

Abstract

Background: Individuals with Spinal Cord Injury (SCI) often suffer from neuropathic pain which is often disabling and negatively affects function, participation, and Quality of Life (QoL). Pharmacological treatments lack efficacy in neuropathic pain reduction hence studying alternatives to drug treatment is necessary. Preclinical evidence of various aerobic exercises has shown positive effects on neuropathic pain but scientific studies investigating its effect in the SCI human population are limited. Methodology: This study is a double-blind, parallel, two-group, randomized controlled trial that aims to evaluate the effectiveness of aerobic exercise programme on neuropathic pain and quality of life (QoL) in individuals with chronic paraplegia. Thirty individuals with chronic paraplegia with the neurological level of injury from T2 to L2 will be recruited from the rehabilitation department at a super specialty hospital based on the inclusion criteria. Using a 1:1 allocation ratio the participants will be randomly assigned to one of the two groups. The intervention group will perform high-intensity interval training (HIIT) aerobic exercise using an arm ergometer based on their peak heart rate and the control group will perform free-hand arm aerobic exercise. In both groups, the intervention will be delivered as 30-minute sessions, four times a week for 6 weeks. Outcome measures: International Spinal Cord Injury Pain Basic Data Set Version 3.0 will be used for diagnosing and assessing neuropathic pain and its interference with day-to-day activities, mood, and sleep. The International Spinal Cord Society (ISCoS) QoL basic data set will be used to assess QoL and 6 Minute Push Test distance will be used to assess peak heart rate and aerobic capacity. Discussion: The effectiveness of the aerobic exercise Programme will be assessed based on the changes in neuropathic pain score and its interference with day-to-day activities, mood, sleep, QoL, and aerobic capacity after 3 weeks mid-intervention and after 6 weeks post-intervention. The trial will provide new knowledge about the effectiveness of the aerobic exercise Programme in improving neuropathic pain and QoL in individuals with chronic paraplegia. Trial Registration: The trial is registered with the Clinical Trials Registry- India on 8 August 2023 with registration number CTRI/2023/08/056257.
