Mobility, prosthesis use and health-related quality of life of bilateral lower limb amputees from the 2008 Sichuan earthquake

Background: The 2008 Sichuan Earthquake resulted in many amputees, yet due to the rare incidence, few studies have explored the rehabilitation outcomes and quality of life of bilateral lower limb amputees after major natural disasters. Objectives: To evaluate rehabilitation outcomes of 17 young and adult bilateral lower limb amputees under the StandTall rehabilitation programme and to identify factors associated with successful functional recovery of bilateral amputees after large-scale disasters. Study Design: Cross-sectional study. Methods: Mobility (amputee mobility predictor), prosthesis use (Houghton Scale) and health-related quality of life (Trinity Amputation and Prosthesis Experience Scale, Short Form 12) were evaluated through questionnaires and performance-based assessments. Means of scores were compared using T-tests. Results: Subjects with bilateral through-knee or transtibial amputations had less activity restriction (p < 0.01) and higher mobility (p = 0.03). Subjects using prostheses more than 50% waking time had better general adjustment (p = 0.02) and less functional restriction (p = 0.01). Exercise and education were associated with higher mobility (p = 0.06) and mental quality of life, respectively (p = 0.09). Conclusions: Amputation level and knee joint salvage, prosthesis use, exercise and education were associated with better rehabilitation outcomes including ambulation, adjustment and quality of life in bilateral lower limb amputees from the 2008 Sichuan Earthquake.
