Effect of Foot Core Control Training on Dorsiflexion Function and Gait Biomechanical Characteristics of Patients With Chronic Plantar Fasciitis
Sponsor: Peking University Third Hospital
Summary
The pain and abnormal gait postures observed in CPF patients may be associated with impaired foot function. However, few studies have examined the dorsiflexion function of the big toe in CPF patients, and the effectiveness of foot core control training in alleviating pain and improving gait remains unclear. Restricted movement of the metatarsophalangeal joint (MTPJ1) may severely compromise foot function, leading to gait pattern alterations and subsequent instability. To address this, our study aims to improve symptoms, functional outcomes, and gait through foot core control training interventions. We recorded kinematic parameters and biomechanical data during the foot's plantar phase at toe-off before and after functional training for CPF patients. Comparative analysis between intervention groups revealed whether foot core control training can effectively enhance big toe dorsiflexion function and gait biomechanics in CPF patients. This research clarifies the therapeutic efficacy of foot core control training for CPF patients.

Interventions
Foot core control training
(1) Toe Yoga : When MTPJ1 actively dorsiflexes, the other four toes remain in contact with the ground. The subject lifts the big toe while the remaining four toes stay on the ground; conversely, when the big toe contacts the ground, the other four toes lift upward, alternating this pattern. (2)Doming: While keeping MTPJ1 in contact with the ground, elevate the foot arch. This exercise strengthens intrinsic foot muscle strength, helping stabilize the arch and first metatarsal. The subject tightens the toes, bringing the forefoot toward the heel to form and enhance the arch. Maintain all toes firmly planted on the ground, ensuring no ankle inversion, no forced flexion or extension of toes, and hold at maximum position. Perform training seated to avoid compensatory movements by external muscles during exercise. (3) Toe Abduction Exercises（4）Dynamic Exercise Progression
CPF Conventional training
The key points of the exercise are as follows: (1) Fascia ball release of plantar fascia (2) Plantar fascia stretching (3) Gastrocnemius muscle stretching (4) Toe grab towel
