“…Given the fact that more than 50 studies were identified, studies with a sample size less of than 10 participants were excluded (n = 27). Two studies were found [ 36 , 37 ] that partially included the same study population (in one study persons with a Syme amputation were included and in the other study they were excluded). The former study was included in this study [ 36 ].…”

ObjectiveTo systematically review the literature on the metabolic costs of activities of daily living (ADL) in persons with a lower limb amputation (LLA).Data sourcesA literature search was undertaken in the Pubmed, Embase, CINAHL, CENTRAL, and PsycINFO databases using keywords and synonyms for LLA, metabolic costs, and ADL. The last search was performed on November 29th, 2017.Study selectionStudies were included if they met the following 2 criteria: participants were adults with a (unilateral or bilateral) LLA and metabolic costs were measured while participants performed a physical activity or ADL.Data extraction and synthesisData of 1,912 participants from 61 studies were included in the systematic review and meta-analysis. The studies used different terms to describe metabolic costs. Participants were recruited in different settings, relatively healthy, with few comorbidities. Limited data were available on metabolic costs of other activities than walking with a prosthesis. A linear mixed model analysis was performed based on the means reported, with study as unit of analysis and test results of different groups and measurement conditions as repeated measures within the unit of analysis. Predictors entered in the analysis were e.g. level and reason of amputation, age, weight, and height. During walking, oxygen consumption (ml O2/kg/min) and heart rate (beats/min) increased with a higher walking speed and a more proximal amputation. Additionally, oxygen consumption was determined by the interaction terms walking speed x amputation level and walking speed squared. Heart rate was determined by the interaction term walking speed squared.ConclusionDuring walking, oxygen consumption (ml O2/kg/min) and heart rate (beats/min) increased with a higher walking speed and a more proximal amputation. Data on metabolic costs of other activities were limited. The poor quality of the studies and the relatively healthy participants limited generalizability of the results of the meta-analysis.

“…Mengelkoch et al 10) demonstrated that the energy cost and performance of below-knee amputees was disadvantageous during walking and running activities compared to non-amputee runners. Furthermore, it is known that the energy cost of physical activities is higher in above-knee amputees compared with below-knee amputees 11) . From these factors, it can be assumed that the energy cost of physical activities is higher in the amputation group compared with the non-disabled group.…”

The aim of this study was to investigate the influence of amputation on match performance in amputee soccer by comparing amputee and non-disabled soccer players. Methods: We recruited 12 Japanese amputee soccer players and 12 Japanese non-disabled university soccer players in this study. Match performance data were collected across five matches. Total distance and high-intensity running (HIR: ≥13 km⋅h-1) were collected using global positioning systems technology. Heart rate (HR) was recorded using short-range radio telemetry. In addition, ratings of perceived exertion (RPE) were assessed immediately after the first and second halves of match play using the Borg RPE scale. Results: The HR response and RPE were significantly different between the amputation group and non-disabled group (p < 0.01). The mean HR, mean %HR max , and RPE were 176.8 ± 7.9 beats⋅min-1 , 96.3 ± 4.6%, and 15.8 ± 1.3, respectively, in the amputation group and 144.4 ± 15.6 beats⋅min-1 , 72.2 ± 7.8%, and 13.4 ± 2.0, respectively, in the non-disabled group. Conclusion: Results of this study indicate that HR response and RPE are affected by amputation. These findings would indicate that the energy cost of physical activities is higher in the amputation group than in the non-disabled group.

“…However, due to the limited number of prosthetic users available for this study, we performed a prior power analysis to identify the minimum sample size necessary to yield results of sufficient power and confidence for the known-groups construct validity assessment. The power analysis was conducted based on values for walking speed (no walking aid) from persons with transfemoral amputation and transtibial amputation [38]. The mean walking speed (SD) was: 65.64 m min -1 (4.18) and 79.02 m min -1 (11.26) for persons with transfemoral amputation and transtibial amputation, respectively, with an estimated difference of 13.4 m min -1 between the groups.…”

Purpose: To investigate the internal consistency, convergent and known-groups construct validity of the Figure-of-Eight Walk Test with two novel conditions in persons with lower limb amputation, and to examine differences in walking performance between the three conditions within a group of persons with transtibial amputation and transfemoral amputation/knee disarticulation. Materials and methods: 50 adults with unilateral amputation participated, 28 of whom had undergone a transtibial amputation and 22 a transfemoral amputation/knee disarticulation. Three Figure-of-Eight Walk Test Conditions were investigated: 1) walking at a self-selected walking speed, 2) walking while carrying a tray with two cups of water and 3) walking on uneven terrain. Internal consistency was evaluated using Cronbach's alpha. Convergent construct validity was examined by analysing the relationship between the Figure-of-Eight Walk Test parameters and performance-based parameters (Amputee Mobility Predictor, Ten-Meter Walk Test, Six-Minute Walk Test) and self-report measures (Prosthetic Limb Users Survey of Mobility, Activities-specific Balance Confidence Scale) using Spearman's rankorder correlations. Known-groups construct validity was assessed by comparing the Figureof-Eight Walk Test parameters based on anatomical level of amputation. Friedman's test and posthoc analysis was used to examine differences between the walking conditions within each group. Results: Cronbach's alpha coefficients of the Figure-of-Eight Walk Test parameters for all three conditions ranged from .89 to .99. The Figure-of-Eight Walk Test time and steps parameters demonstrated moderate to good correlation (r = -.50 to -.77) for performance-
