the effectiveness of ultrasound treatment in the management of plantar fasciitis

Conditions: Plantar Fascitis

Summary: 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.

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
