Abstract: Prosthetic outcome of lower limb amputees describes how the patients perform by means of health, illness, function and quality of life. It can be measured by self-reported assessment instruments and performance-based assessment instruments which have been widely used in clinical trials and research. Although significant number of studies has been done on the prosthetic outcomes of persons with amputation due to diabetes and vascular disease, little study has been carried out for the young amputees suffered from traumatic amputation due to natural disaster. Therefore, this study focuses on investigating the prosthetic outcomes for young trauma-related lower limb amputees aging from 10 to 39 years due to natural disaster. Thirty-eight amputee participants including eighteen transtibial amputees, three knee disarticulation amputees and seventeen transfemoral amputees were recruited during follow-up visits to the Deyang Disabled Persons' Federation Hong Kong Red Cross Rehabilitation and Prosthetics & Orthotics Center in Sichuan, China. Thirteen normal subjects were also recruited as control group for comparison. Step Activity Monitor (SAM) was installed on amputees' prostheses and normal subjects' ankles to measure their physical activities in daily living. Prosthetic Evaluation Questionnaire (PEQ) was used to assess the functional outcomes and quality of life of the amputee subjects in nine different domains including ambulation, residual limb health, utility, appearance, sounds, frustration, perceived response, social burden and well-being.
Analysis by one-way ANOVA showed that the physical activities of unilateral transtibial and transfemoral amputees were 74% and 46% respectively of the normal subjects (p<0.05) in terms of number of steps per day. No significant difference was found between knee disarticulation amputees and normal subjects in terms of physical activity. Health-related quality of life had no difference in different amputation levels in terms of PEQ score. The rehabilitation outcomes did not show any significant difference on gender and age factors, indicating that the age and gender had not much influence on young traumatic amputees. There was also no significant difference among the three visits (1-month time per visit), showing that the rehabilitation outcomes were steady within 3 months. Prosthetic compliance was good with daily wearing time of more than 12 hours. PEQ scores of all domains were above 60 out of 100 indicating a satisfactory quality of life. However, no significant correlation was found between SAM data and PEQ scores. The results of the current study have addressed the physical activity and quality of life of young lower limb amputees, which have seldom been investigated from the previous studies. Their comments to prosthetic management were very positive and they were able to return to close to normal lives. This research has also developed a baseline for the prosthetic outcome measures, which could assist in establishing immediate post-disastrous prosthetic treatment protocol, creating a platform for comparison of different clinical studies and justifying the value and existence of prosthetic services in the healthcare system.
