Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Mid-foot osteoarthritis
Subjects will be treated with Electromagnetic Transduction Therapy (EMTT) using the Curamedix MAGNETOLITH device. Treatments will be administered twice per week, for four weeks. Each treatment will have the following settings: level 8, 8Hz, and 10,000 pulses andwill take about 15 to 20 minutes. Treatments will be spaced 2-3 days apart.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual Analog Scale (VAS) for Pain
Time Frame: Baseline, 3 weeks, 3 months, 6 months
The VAS is a 11-item questionnaire assessing pain. Using a scale of 0 = no pain to 10 = worst pain. Total scores range from 0 - 110, lower scores indicating lower pain and higher scores indicating greater pain.
Baseline, 3 weeks, 3 months, 6 months
Foot and Ankle Ability Measure (FAAM)
Time Frame: Baseline, 3 weeks, 3 months, 6 months
The Foot and Ankle Ability Measure (FAAM) ADL is a 21-item self-report questionnaire measuring Activities of Daily Living. Each item is scored on a 5-point Likert scale (4 to 0) from 'no difficulty at all' to 'unable to do'. Item score totals, which range from 0 to 84 are reported in percentage scores. Higher scores represent higher levels of function, with 100% representing no dysfunction.
Baseline, 3 weeks, 3 months, 6 months
