Background: The aim of this study is to investigate the effect of orthopedic insoles and gait strategies on kinematic walking parameters in individuals with heel spur.
Methods: A total of 15 patients with heel spur and 15 healthy individuals with similar average height, weight, and age were selected through convenience sampling. The Vicon motion analysis system, equipped with 6 high-speed cameras and a sampling frequency of 100 Hz, was used to evaluate spatiotemporal and spatial walking parameters. A mixed-design repeated measures ANOVA was employed at a significance level of 0.05.
Results: Toe-in gait resulted in decreased cadence, ipsilateral foot-off, step length, step time, stride time, step width, and walking speed, while toe-out gait increased ipsilateral foot-off in both groups. In the heel spur group, silicone insoles and heel cups led to increased cadence, stride length, and walking speed, while reducing double-support percentage, stride time, and visual pain intensity compared to gait strategies. Silicone insoles increased step length (compared to normal walking and toe-in gait), decreased step time (compared to normal walking, heel cups, and toe-out gait), and reduced single-support percentage (compared to normal walking and toe-out gait). In heel spur patients, toe-out gait increased double-support percentage and contralateral foot-off, while toe-in gait decreased double-support and single-support percentages.
Conclusion: Walking with silicone insoles and heel cups are optimal interventions for improving and enhancing spatiotemporal walking parameters. Silicone insoles are the most effective intervention, while toe-in gait poses a potential risk factor for individuals with heel spur.
