Effect of Foot Core Control Training on Dorsiflexion Function and Gait Biomechanical Characteristics of Patients With Chronic Plantar Fasciitis

(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

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
