The attached recruitment brochure will be distributed to physician's offices, and possibly placed as an ad in the newspaper. Potential participants will call the enclosed number and an appointment will be arranged to be evaluated at our research facility in Carterville, IL. During their initial evaluation which will take 30 minutes to 1 hour, each participant will complete medical history pertinent to plantar fasciitis and questionnaires regarding symptoms and physical activity. The research participants will then stand on the tssfad1 device for 5 to 10 minutes during which time their triceps surae flexibility will be assessed by measuring the distance from their heel to the platform at the 30-degree setting. Measurements for each foot will be taken with a distance sensor every 5 seconds for a 5 minute period.~The investigators will then use a random number generator program from www.random.org to generate a number between 1 and 100. Participants with an odd number will be assigned home use of standard night splints. Those with an even number will be provided with a TESS unit to be used at home a minimum of 5 minutes twice per day.~The participants will use their device for 6 weeks. They will receive a check in phone call at the 3 week mark of their participation.~Contact numbers will be given to each participant should they have any questions or concerns during the six-week interval. Each participant will be asked to maintain a daily log of their pain level on a visual analog scale and of their estimated time using each device.~Participant's random number will be used to link data in the study to the participant. The investigators will not be using patient identifiable information such as name, date of birth, medical record number, or other personal information for the record.
A set of 100 patients previously diagnosed with plantar fasciitis will be given initial questionnaires about their symptoms and randomly assigned either night splints or the novel calf stretching device. The participants will use each device for 6 weeks. At the end of those 6 weeks, they will return for a follow up questionnaire. The answers in the questionnaire will be analyzed to compare the effectiveness of night splints to calf stretching.
