aThis participant was excluded from the functional MRI analysis.
M/F = male/female; MAL = Motor Activity Log scores: how frequently one-handers use their prosthesis in an inventory of 27 daily activities (e.g. taking money out of wallet etc.). Scores of 0 = never, 1 = sometimes, 2 = very often. The sum of all items was divided by the highest possible score, such that individuals were rated on a scale ranging from 0 to 1. Prosthesis usage time relates to wear time, 1–5: the scale for prosthesis usage time: 0 = never; 1 = rarely; 2 = occasionally; 3 = daily, <4 h; 4 = daily, 4–8 h, 5 = daily, >8 h.
