Objective Determine efficacy of the novel WiiNWalk intervention on walking-related outcomes in older adults with lower limb amputation. Design Multi-site, parallel, evaluator-masked randomized controlled trial. Setting Home-setting in three Canadian cities. Participants Community-dwelling lower limb prosthesis users over 50 years of age. Interventions The WiiNWalk group (n = 38) used modified Wii Fit activities for prosthetic rehabilitation. The attention control group (n = 33) used Big Brain Academy: Wii Degree, comprising of cognitive activities. Both groups completed a 4-week supervised phase with three 1-h sessions/week in groups of three overseen by a clinician via videoconferencing and a 4-week unstructured and unsupervised phase. Main Measures Primary outcome was walking capacity (2 min walk test); secondary outcomes were balance confidence (activities-specific balance confidence scale), dynamic balance (four-step square test), and lower limb functioning (short physical performance battery). Outcomes were compared across time points with repeated measures analysis of covariance, adjusting for baseline and age. Results Mean age was 65.0 (8.4) years, with 179.5 (223.5) months post-amputation and 80% transtibial amputation. No group difference in a 2 min walk test with an effect size: 1.53 95% CI [−3.17, 6.23] m. Activities balance confidence was greater in the WiiNWalk group by 5.53 [2.53, 8.52]%. No group difference in the four-step square test −0.16 [−1.25, 0.92] s, nor short physical performance battery 0.48 [−0.65, 1.61]. A post-hoc analysis showed the greatest difference in balance confidence immediately after an unsupervised phase. Conclusions The WiiNWalk intervention improved balance confidence, but not walking-related physical function in older adult lower limb prosthesis users. Future rehabilitation games should be specific to the amputation context. Clinical Trial Registration number, NCT 01942798.
ObjectiveThe aim of this study was to document long-term symptoms and functional results following war-related knee disarticulation, trans-femoral amputation, and hip disarticulation.MethodsAn observational cross-sectional study was conducted in a 7-day recreational camp in Iran. One thousand patients with unilateral hip disarticulation, trans-femoral amputation and knee disarticulation due to war-related injuries were invited to undergo a thorough physical examination. Among the invited persons, 58.7% (587 subjects) responded to our invitations. A complete examination related to phantom pain, phantom sensation, stump pain, back pain, and sound limb joints pain with a self-constructed questionnaire was performed. In addition, Amputee Mobility Predictor (AMP) instrument with a prosthesis was completed to assess the function of patients.ResultsThe mean duration of time since amputation was 22 years. The most common symptoms reported by participants were phantom sensation (82%), back pain (69%), and phantom pain (63%). In addition, total scores of AMP with a prosthesis in persons with knee disarticulation and trans-femoral amputations were 20.8 and 28, respectively.The knee disarticulation was associated with higher scores of AMP with a prosthesis compared to transfemoral amputation (p < 0.01).ConclusionThe results of this study showed that patients with lower limb amputation suffer from significant clinical and functional problems. The findings may be useful to adopt new strategies in planning rehabilitation programs to improve quality of life and health status of patients with war-related lower limb amputation.Level of EvidenceLevel IV, Therapeutic study.
