Shortfoot exercises are often recommended to strengthen intrinsic foot muscles and to prevent excessive decrease of medial longitudinal arch height. Objective: To investigate the effects of short-foot exercises on navicular drop, foot posture, pain, disability, and plantar pressures in pes planus. Design: Quasi-experimental study. Setting: Biomechanics laboratory. Participants: A total of 41 participants with pes planus were assigned to the short-foot exercises group (n = 21) or the control group (n = 20). Intervention: Both groups were informed about pes planus, usual foot care, and appropriate footwear. Short-foot exercises group performed the exercises daily for 6 weeks. Main Outcome Measures: Navicular drop, Foot Posture Index, foot pain, disability, and plantar pressures were assessed at the baseline and at the end of 6 weeks. Results: Navicular drop, Foot Posture Index, pain, and disability scores were significantly decreased; maximum plantar force of midfoot was significantly increased in short-foot exercises group over 6 weeks (P < .05). No significant differences were determined between the baseline and the sixth week outcomes in control group (P > .05). Conclusions: Six-week short-foot exercises provided a reduction in navicular drop, foot pronation, foot pain, and disability and increment in plantar force of medial midfoot in pes planus.
