The effect of prosthetic alignment on the stump temperature and ground reaction forces during gait in transfemoral amputees

•The thermal images can support the prosthetist during the alignment procedure.•A poor prosthetic alignment produces an irregular heat distribution on the stump.•The GRF of the prosthetic limb is a useful indicator for the alignment procedure.•The GRF of the sound limb is not helpful indicators to aid the alignment procedure.•Symmetry indices do not improve after properly aligning the prosthesis.
