Abstract

Introduction: Apart from mental disorders, other complications that have been reported in some patients with Post-Traumatic Stress Disorder (PTSD), include physical pain and being quick to fatigue, which can severely affect the patients’ daily life. Therefore, this study aims to evaluate the relationship between PTSD and physical fatigue in people with PTSD. Method: 18 military men with (n = 9) and without PTSD (n = 9), with an age range of 45–60 years, volunteered to participate. They were randomly assigned into two groups: PTSD and non-PTSD groups. Recording of the surface electromyography (EMG) in a specific muscle was conducted twice in both groups, once at baseline and then again after a single session of fatiguing exercise. Data were analyzed by ANOVA with repeated measure (2✕2) at the significance level of 0.05. Results: Results showed that there was a significant main effect of intervention on electrical activity and neural conduction variables in the PTSD group (p = 0.04, p = 0.02). There was also an effect of time for the both variables (P < 0.001). Conclusion: Stress disorders may affect the time to fatigue in PTSD patients and subsequently cause some difficulties in their daily life. © 2020 Elsevier Ltd
