Effects of treadmill training with load addition on non-paretic lower limb on gait parameters after stroke: A randomized controlled clinical trial

•Load use as a restraint for the movement of non-paretic lower limb is proposed.•Currently, only immediate effects of this practice are available.•Stroke patients performed gait training with and without load addition, for two weeks.•Kinematic gait parameters were improved after training and maintained at follow-up.•Load addition did not provide additional benefits to gait training.
