Chronic musculoskeletal pain, phantom sensation, phantom and stump pain in veterans with unilateral below-knee amputation

: Background and aims Many individuals with lower limb loss report concerns about other musculoskeletal symptoms resulting from amputation. The objective of this study was to assess chronic musculoskeletal pain in Iranian veterans with unilateral below-knee amputation. Methods The participants agreed to take part in a health needs assessment and were interviewed face-to-face by trained interviewers. The assessment consisted of demographic information, wearing a prosthesis, pain locations in extremities, stump complications, severity of pains related to amputation and low back pain. Results Of 247 unilateral below knee amputees, 97.9% wore a prosthetic limb and times walking or standing with the prosthesis were 12.47 ± 3.84 and 4.22 ± 3.53 h a day, respectively. Low soft tissue coverage of the stump (15.4%) and symptomatic osteoarthritis in the contralateral lower extremity (40.1%) were the most common complications. The prevalence of stump pain, phantom sensations, phantom pain, low back pain, and knee pain was 84.2%, 77.3%, 73.7%, 78.1%, and 54.7% respectively. The odds ratio of stump pain in amputees with phantom pain was 2.22 times higher than those who did not experience phantom pain [OR = 2.22 (CI: 1.19-4.17); p = 0.012] and the odds ratio of low back pain was higher in amputees with stump pain [OR = 3.06 (CI: 1.50-6.21); p = 0.002]. Conclusions This research enhances our understanding of comorbid musculoskeletal problems in below-knee amputees which can help health providers to identify rehabilitation needs and emphasizes the importance of regular assessments. Implications These findings underline the importance of paying closer attention to different dimensions and aspects of musculoskeletal complications in veterans with unilateral below-knee amputation.
