THE MANAGEMENT OF PLANTAR FASCIITIS WITH A MUSCULOSKELETAL ULTRASOUND IMAGING GUIDED APPROACH FOR INSTRUMENT ASSISTED SOFT TISSUE MOBILIZATION IN A RUNNER: A CASE REPORT.

background/and purposeMusculoskeletal ultrasound imaging (MSK US) is an emerging diagnostic tool in physical therapy, which allows for dynamic visualization of tissues in real time. Plantar fasciitis is a common condition causing heel and arch pain and has been related with degenerative changes in the plantar fascia resulting in tissue thickening. Instrument Assisted Soft Tissue Mobilization (IASTM) is an intervention that allows clinicians deep penetration to treat tissues. The mechanical forces caused by IASTM might cause localized tissue trauma leading to stimulation of the body's natural inflammation and healing processes. The purpose of this case report is to demonstrate the use of ultrasound imaging to guide the decision-making process and to discern the optimal location for the application of IASTM. CASE DESCRIPTION: The subject was a 46-year-old female yoga practitioner and runner, who presented with right foot pain. The clinical impression was formulated based on the combination of traditional physical therapy examination procedures and MSK US imaging findings of the plantar fascia demonstrating thickness and tendinosis like changes within the plantar fascia 3 cm distally from the calcaneus. OUTCOMES: The subject was seen for eight treatment sessions over four weeks, at which time the goals of normal ankle dorsiflexion, no pain with palpation of the plantar fascia, negative windlass test, and no reported pain during gait were achieved. DISCUSSION: This case report illustrates the use of MSK US imaging as a method to objectively assess tissue quality and guide decision-making when managing patients with plantar fascia related pain. MSK US was used to determine the optimal location for the application of IASTM during the conservative management of a runner with plantar fasciitis. LEVEL OF EVIDENCE: Therapy, Level 5.
