Abstract
Background:Lower limb amputation is an emotionally devastating condition that causes a complete change in the quality of life, may lead to phantom limb pain in most of the cases, and puts the individual in a high risk of developing psychological disorders. The objective of this study is to evaluate the consequence of adding virtual reality (VR) to a traditional exercise program on pain, mental status, and psychological status in traumatic unilateral lower limb amputees (LLAs). Methods:Thirty-two traumatic LLAs were randomly assigned into two equal groups in this randomized control trial. Participants accomplished a post-fitting exercise program at least 6 months before enrollment; the control group (CG) underwent a traditional rehabilitation program, and experimental group (EG) had the same program, in addition to VR training. Data were collected before and after 6 weeks of intervention using visual analog scale (VAS) for pain, Beck's depression inventory (BDI) for depression, and 12-item short form survey for mental health summary (MHS) and physical health summary (PHS). Results:Thirty-two amputees (29 males and 3 females) were included with mean age in CGs and EG (27.6 ± 4) and (27.6 ± 7.6) years, respectively. Postintervention, the VAS score was significantly reduced only in EG (P = 0.003). Both groups showed significant improvement in BDI, MHS, and PHS (P < 0.05). However, the EG showed a superior significance in BDI and MHS scores (P < 0.05). There was no significance between groups in PHS score. Conclusion:Adding VR to conventional training is beneficial in decreasing pain and in improving depression and MHS of traumatic unilateral LLAs.
