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.
