Article Synopsis
  • The study aimed to analyze the landing mechanics and foot muscle strength in gymnasts, cheerleaders, and non-athletes, particularly comparing barefoot and shod landings.
  • Results showed gymnasts had better performance in landing stability and force metrics compared to non-athletes, but cheerleaders' landing mechanics were similar to both groups.
  • Overall, wearing shoes decreased initial ground reaction forces during landings, but did not have a significant impact on stabilization times across the groups.

Background: Evaluating the strength of the small muscles of the foot may be useful in a variety of clinical applications but is challenging from a methodology standpoint. Previous efforts have focused primarily on the functional movement of toe flexion, but clear methodology guidelines are lacking. A novel foot doming test has also been proposed, but not fully evaluated.

Purpose: The midfoot is instrumental to foot function; however, quantifying its roles in human movement has been difficult. A forceful dynamic activity like landing may help elucidate the midfoot's contribution to foot energetics and function. The main purpose of this study was to measure midtarsal joint kinematics and kinetics during a barefoot single-leg landing task.

Introduction: Weakness of foot muscles may contribute to a variety of loading-related injuries. Supportive footwear may contribute to intrinsic foot muscle weakness by reducing the muscles' role in locomotion (e.g.

Background: Quantifying the strength of the intrinsic foot muscles has been a challenge for clinicians and researchers. The reliable measurement of this strength is important in order to assess weakness, which may contribute to a variety of functional issues in the foot and lower leg, including plantar fasciitis and hallux valgus. This study reports 3 novel methods for measuring foot strength - doming (previously unmeasured), hallux flexion, and flexion of the lesser toes.
