Brief Summary

This study is a single armed prospective case series designed to evaluate the efficacy of treating common structural-related foot ailments (i.e. plantar fasciitis, metatarsalgia, and/or hallux valgus) with a high quality non-custom made arch support. It is believed that these conditions are the result of inadequate or poorly fitted arch supports resulting in a lack of structural correction in the foot while weight bearing. Over-the-counter insoles are believed to counteract the shortcomings in foot structure that result in these painful conditions. In this study, it is proposed that changes in foot morphology can be measured quantitatively using weight bearing CT Scan (Computerized Tomography) and X-rays of the subject with and without the arch supports. Subjects will also answer questions from a validated series of questionnaires pertaining to their foot condition and generalized health and activity level.

The study is a minimal risk study, with all subjects receiving the arch supports being investigated. There is no placebo offered. Initial evaluation of all subjects will include all imaging and measurements. Collection of subjective responses will occur after 4 weeks, 8 weeks, and 12 weeks of treatment.

Detailed Description

1. Background and Significance

Foot orthoses are arch supports that can be worn in the shoes, and are designed to relieve pain by providing support to various areas of the foot to eliminate or reduce excessive mechanical forces. Most commonly, these devices are used as part of the treatment protocol for a variety of common foot ailments including painful plantar fasciitis and pronation. A variety of musculoskeletal pains have been shown to be reduced, and stability in ambulation can be improved by adding arch support to the shoes. Most importantly, previous studies have demonstrated that the structure of the foot can be altered, and with that the function of the foot, when orthoses are used.

Previous studies have demonstrated multiple biomechanical and clinical benefits of using foot orthoses and arch supports. These devices have been shown to alter foot positioning and forefoot pressure during walking, reducing heel and forefoot pressures, decreasing impact forces, and improving comfort. Cadaveric studies confirm that orthoses enhance ankle and subtalar joint stability, correct abnormal rotations, improve arch alignment, and increase arch height under simulated load. Clinical studies involving military personnel found that wearing arch supports significantly reduced stress fracture incidence and improved comfort. Additionally, arch supports were associated with decreased lower back pain after prolonged use. Research also indicated that orthotic devices reduce tibial internal rotation, influencing the mechanical function of proximal structures like the ankle and leg. Furthermore, orthoses positively impacted foot deformities, pain (foot, knee, hip, and back), and balance, as demonstrated by radiographic and center-of-pressure analyses, indicating overall improvements in stability and symptomatic relief.

The goal of the current study is to investigate the clinical and biomechanical effects of arch-support insoles in common foot pathologies including plantar fasciitis, and metatarsalgia.

2. Specific Aims and Objectives

The objective of this study is to measure the structural changes that occur in the foot when wearing arch supports, and how these changes correlate with overall relief of common structural-related foot ailments; plantar fasciitis, metatarsalgia, and/or hallux valgus

Specific Aim #1:

Measure any changes that occur in the position and alignment of the foot bones relative to one another using weight bearing radiographs and weight bearing CT scans, with and without over-the-counter arch supports under the sole of the feet.

Hypothesis: Arch supports (orthoses) will alter the positioning and alignment of the bones of the foot when standing. Any changes will be measurable in three dimensions, using both weight bearing CT scans and standard anterior-posterior and lateral radiographs.

Specific Aim #2:

Demonstrate if there is a correlation between symptomatic relief of painful foot conditions including plantar fasciitis and metatarsalgia pain using validated clinical scores and quality of life measures.

Hypothesis: Painful foot conditions will improve when subjects wear over-the-counter arch supports on a regular basis, as demonstrated by validated subjective scoring.

Subject Recruitment:

Subjects will be recruited from the clinicians in the Division of Podiatry under the Department of Orthopaedics. Additionally, the sponsor, Good Feet Worldwide has a trade store the MGH service area, and will allow us to promote the study at their location with an advertisement poster. Potential subjects from the trade store will be referred to our clinics for screening and, when appropriate, recruited for the study.

Potential subjects will contact the principal investigator, Dr. Adam Landsman for preliminary screening and if they are able to satisfy the basic criteria, will be invited for formal screening. If qualified, they will be enrolled to begin the study. In order to avoid any undue pressure, all potential subjects who are patients of one of the Investigators will be given the option to do any or all of the following:

• Offer patients the opportunity to take home the Consent Form, and call back if they wish to participate
• Offer to connect the patient with other health care providers to discuss participation.

All study subjects will be screened and evaluated at the Foot and Ankle Clinic at MGH Waltham. Screenings and enrollments will take place on Tuesdays and Wednesdays, during dedicated research time.

The conditions being examined here are common among all races and genders, and enrollment is open to all. There have been limitations placed on subject age, as this age group is most likely to experience the conditions being studied.
