A convenience sample based on availability of tibial stress fracture cases at local Sports Medicine Clinics was selected. The study was designed to determine if electric field stimulation accelerates the healing of tibial stress fracture and whether there are gender effects. Only posteromedial mid to distal third and proximal medial tibial condylar stress fractures were investigated. Four imaging examinations were performed at diagnosis radiographs, bone scan, MRI and CT. All subjects were treated identically in a double blind fashion using active or passive electric field stimulator devices active units apply a sinusoidal wave of 3-6 V, 60 KHz, 5-10 mA, worn 15-20 hours per day, and other standardized rehabilitation treatments, until healed but not longer than 6 months. Subjects were considered healed when hopping on the affected limb was longer painful. A second MRI examination was performed for follow-up comparison. A grading system is being developed for each of the diagnostic methods and the ability of the MRI grading system is being assessed to predict time to recovery.
