“…One study investigated the effect of various prosthetic accommodation durations [ 35 ]. Additionally, 28 studies investigated the correlation between real-world measurements and other variables, such as performance-based measures [ 28 , 33 , 34 , 37 , 38 , 47 , 50 , 53 , 56 , 61 ], self-reported outcomes [ 4 , 26 , 33 , 35 , 42 , 49 , 61 , 67 ], K-level [ 45 , 48 , 58 ], measures of gait quality [ 64 ], fall and injury incidence [ 30 ], aerobic capacity [ 28 ], demographic factors [ 26 , 61 ], limb fluid volume [ 43 ], clinical scores [ 62 ], comorbidities [ 47 ], stride-to-stride fluctuations [ 53 ], step variability [ 56 ], and prosthetists’ perceptions of participants’ prosthetic use [ 41 ]. Eight studies performed comparisons between groups, based on the etiology of amputation [ 26 ], level of amputation [ 51 ], K-level [ 46 , 52 , 57 ], surgery treatments [ 55 , 66 ], and chronic physical condition [ 60 ].…”
