Objective: To clarify the effect of feedback using an insole-type load-monitoring device (loadsol®) on partial weight-bearing (PWB) practice compared with biofeedback using a conventional device.Methods: The subjects were 20 healthy adults (10 female, 10 male; age: 20.6 ± 1.2). The study design was a randomized, crossover trial. The intervention group received visual feedback (FB) from an iPad mini screen that concurrently displayed the weight-bearing information from the loadsol® insoles. The control group received visual FB from an analog scale. The protocol of two-thirds of PWB walking using a crutch consisted of two practice sessions with FB and three measurement sessions without FB. The outcome measure was set as the average peak force (Avg. Pf) in each measurement session.Results: The Avg. Pf was significantly lower in the intervention group than in the control group in the immediate measurement after the first practice and after the interval (p<0.05). The Avg. Pf in the intervention group approximated the target PWB.Conclusion: The results suggest that the loadsol® can provide concurrent and trial-immediate FB. FB using the loadsol® was effective for early acquisition and retention when learning PWB. The FB using the loadsol® may be clinically useful for learning PWB.
