Effects of Exercise Versus Exercise and Instrument-Assisted Soft Tissue Mobilization for Plantar Fasciopathy Treatment

Summary

This study compares the addition instrument-assisted soft tissue mobilization (IASTM) to a program of home strengthening and stretching exercises to see whether adding weekly IASTM treatments improves plantar fasciopathy pain and plantar fascia stiffness.

Conditions

• Plantar Fascitis

Instrumental-assisted soft tissue mobilization (IASTM)

Instrumental-assisted soft tissue mobilization (IASTM) will consist of treatment focused on the plantar surfaces of foot, posterior heel, and lower leg. The IASTM will be implemented using Graston Technique Instruments by clinicians trained and certified in the technique. Each 10-minute treatment will consist of two phases: 1) six-minute static phase, which includes tissue status screening and soft tissue mobilization, and 2) four-minute dynamic tissue mobilization phase. The treatment will focus on the web spaces of each toe plantarly, the metatarsal heads, the spaces between metatarsals, the medial and lateral plantar fascia borders, plantar fascia proximal origin, the heel, and the lower leg muscle groups. The targeted soft tissues are the plantar fascia, ankle plantar flexors, heel fat pad, Achilles tendon, and the gastrocnemius-soleus complex.

OTHER

High-Load Strength Training

Participants will perform a heel raise exercise used by Rathleff et al (2015). The exercise will be performed twice daily. While standing with the forefoot on a step, the toes will rest on a partially folded towel, placing them in a maximally dorsiflexed position. The exercise will consist of a maximum ankle plantar flexion followed by maximal dorsiflexion. The concentric plantar flexion and eccentric lowering phases will be 3 seconds, with a 2 second isometric pause in between. The exercise will be performed unilaterally if tolerated by the subject. Otherwise, a bilateral calf raise will be performed until the subject is able to perform the unilateral version. The exercise will be performed every other day and progressed throughout the trial as described by Rathleff and colleagues.

OTHER

Plantar Flexor and Gastrocnemius Stretching

For the plantar flexor stretch (DiGiovanni et al, 2006), subjects will sit and cross the affected leg over the contralateral leg. Placing the affected side fingers on the plantar toes, distal to the metatarsophalangeal joints, they will passively dorsiflex the toes until they feel stretching in the arch of the foot. Subjects will be instructed to hold this stretch for 10 seconds and repeat it 10 times. The gastrocnemius stretch will be performed in supine with a towel placed around the distal foot and the foot actively inverted. With the knee extended, the subject will flex the hip while passively dorsiflexing the foot using the towel. This stretch will be held for 30 seconds and repeated 3 times. Subjects will be asked to perform both stretches three times each day.
