Abstract

Background: Service members who have experienced combat trauma with resulting amputation are at risk for compromised quality of life postamputation. Monitoring mental and physical health in amputees returning from the war is of paramount importance. This study examined changes in physical and mental health-related quality of life in service members following traumatic unilateral, transtibial amputation (TTA) during a 12-week period of rehabilitation before and after receiving a prosthesis. Method: This study is a secondary analysis from a randomized controlled trial (RCT) of military service members starting Military Amputee Rehabilitation Program (MARP) following a traumatic TTA. The study examined change in SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores as two aspects of health-related quality of life. Forty-four injured service members, aged 19 to 46, were recruited into the RCT. Participants were randomized into 12 weeks of MARP plus home neuromuscular electrical stimulation therapy (n = 23) or MARP alone (N = 21) and compared at baseline, 6, and 12 weeks on: SF-36 PCS and MCS scores. Linear mixed models examined time and group differences and their interaction for the MCS and PCS scores. A multivariate mixed model tested whether MCS and PCS scores differed. Results: For the combined rehabilitation cohort, MCS did not differ over 12 weeks (p = 0.27) with scores at week 0 of M = 56.7 (SD = 11.9) and at week 12 of M = 52.7 (SD = 11.4), similar to healthy controls (age = 25–34, M = 51.0, SD = 7.6). Scores did not differ between treatment groups (p = 0.28) with no group by time interaction (p = 0.34). The MCS significantly declined over time (p = 0.05) after adjustment for covariates. PCS improved over 12 weeks (p < 0.0001) in the total rehabilitation group with scores at week 0 of M = 34.0 (SD = 8.1) to M = 41.8 (SD = 8.4) at week 12, significantly lower than healthy controls (age = 25–34, M = 54.1, SD = 6.6). Scores did not differ between treatment groups (p = 0.89), and there was no group by time interaction (p = 0.34). An interaction between the PCS and MCS was observed such that the PCS improved over time, whereas the MCS did not significantly change (p = 0.0005). Discussion: War-injured transtibial amputees are at risk for compromised quality of life during rehabilitation. Self-perceived physical health improved as might be expected from rehabilitation. Self-perceived mental health did not. During rehabilitation, physical healing, psychological adjustment, and lifestyle adaptation are occurring simultaneously. However, more attention may need to be directed toward mental health during rehabilitation.
