The Effectiveness of Ultrasound Treatment in the Management of Plantar Fasciitis

The Effectiveness of Ultrasound Treatment in the Management of Plantar Fasciitis: A Randomized, Placebo-Controlled Study

The purpose of this study is to examine the effectiveness of ultrasound treatment in addition to a program consisting of manual therapy and exercise (stretching and strengthening exercises) to improve pain and function in individuals with plantar fasciitis. Our primary hypothesis is individuals with plantar fasciitis will show a greater improvement in pain and function with ultrasound, manual therapy and an exercise program compared to manual therapy and exercise program alone.

Study Overview

• Status: Unknown
• Conditions: Plantar Fascitis
• Intervention / Treatment: Other: Ultrasound, manual therapy and exercise

Detailed Description

Plantar fasciitis (PF) is a common cause of foot pain, affecting an estimated 2 million people per year.1 Although there are large numbers of people seeking medical attention for this condition, there remains some confusion among health care providers as to the most efficacious treatment and some authors conclude that no data solidly supports effectiveness of treatment.2

Several randomized control studies have been published with respect to treatment of PF with ultrasound. The current literature on the effectiveness of US in individuals with PF is largely inconsistent in the parameters. One study by Crawford and Snaith,3 found the true ultrasound was no more effective than sham ultrasound and the authors concluded that future studies need to clarify ultrasound parameters. In contrast, a recent study that utilized different parameters,4 concluded that the US group showed significant changes in pain and function. Strengthening and stretching exercises are well documented through the literature to improve function and decrease pain in patients with PF.5-8 It has been reported within the literature that patients with PF have subtalar, tarsometatarsal, and first metatarsalphangeal (MTP) joint hypo mobility into dorsiflexion, which reduces dorsiflexion range of motion (ROM) and places the windlass mechanism at a mechanical disadvantage which has been theorized to place increased stress on the plantar fascia.9-12 A variety of studies have explored the effects of manual therapy in conjunction with exercises to address the limitations in ankle dorsiflexion ROM.9-12

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Ultrasound, manual therapy and exercise; This group will receive Ultrasound, manual therapy and exercise	Other: Ultrasound, manual therapy and exercise; The experimental group will receive ultrasound (US) for 3 sessions a week for 4 weeks, with continuous US (1.8 w/cm2, 1 Mega Hz 8 minutes). Manual therapy will include posterior glides to talocrural joint, subtalar lateral glide, a 1st tarsometatarsal joint dorsal glide and extension mobilization to the 1st metatarsophalangeal joint. All participants in each group will be given specific exercises by the investgators targeting intrinsic and extrinsic muscles of the foot and ankle. Specific stretches for the plantar fascia and Achilles tendon, will be performed. Home exercises will be recorded using a log.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain during ADL	The Numerical Rating Scale/Numerical Pain Rating Scale (NPRS) is a pain scale that has been proven to be a reliable and valid outcome measure when used to assess chronic pain	Change measures (baseline and up to 5 weeks)
Range of Motion	Dorsiflexion active range of motion will be measured at baseline and at the conclusion of the study by the other principal investigator. Participants will be in a weight-bearing lunge position with the leg to be measured in front and toes facing the wall. The participant will be asked to maximally bend the knee without lift of the heel.	Change measures (baseline and up to 5 weeks)
Functional foot and ankle measure (ADL and sports)	The Foot and Ankle Ability Measure (FAAM) is a functional outcome measure validated in the physical therapy setting.20 It will be used to measure differences in ability in activities of daily living and sports at the initial evaluation and at the conclusion of the study.	Change measures (baseline and up to 5 weeks)
Heel raises		Change measures (baseline and up to 5 weeks)
Navicular drop	All subjects will be seated in a chair with the hips and knees flexed to 90 degrees. The subtalar joint neutral position will be 1st identified through appropriate technique. Following this, the examiner will identify the most anterior and inferior position of the navicular tuberosity and mark it with a washable fine tip marker. The participant will be asked to hold that position while the height of the navicular tuberosity will be measured with a digital caliper. Following measurements in seated position for both feet, participants will be asked to stand and assume a relaxed stance position. The process measuring the navicular height position with a digital caliper as described above in seated position will be repeated in standing position. The difference between the seated and standing navicular positions will be defined as the Navicular drop.	Change measures (baseline and up to 5 weeks)
