Plantar Fasciitis and the Use of Orthotics as Treatment

Plantar Fascitis Clinical Trial

Official title: A Study Into the Use of Prefabricated Orthotics in Shoes, in Combination With Using Indoor Comfort Sandals With built-in Arch Support vs. the Sole Use of Prefabricated Orthotics in Shoes Alone, for the Treatment of Plantar Fasciitis. A Randomised Control Trial

Status Completed

Clinical Trial Summary

To investigate whether the use of prefabricated Orthotics in shoes, in combination with the use of indoor comfort sandals with built-in arch support, benefits the treatment of plantar fasciitis more than the sole use of prefabricated Orthotics in shoes alone.

Clinical Trial Description

The usual symptom of plantar fasciitis is "first-step pain", though plantar heel pain in general can be broadly associated with plantar fasciitis. Although most of the cases resolve within 10 months, 10% develop chronic plantar fasciitis. The pathomechanics of the condition is assumed to be due to excessive tensile loading, exacerbated by abnormal biomechanics of the legs such as pes planus, leg length discrepancy, and tightness of calf muscles.

Foot Orthotics are commonly used in the conservative treatment of plantar fasciitis. It is thought that foot Orthotics reduce the symptoms of plantar fasciitis by reducing strain in the fascia during standing and ambulation. A handful of randomized controlled trials have evaluated the effects of foot Orthotics from a patient's perspective. However, systematic reviews of these trials have concluded that the evidence for the effectiveness of foot Orthotics in the treatment of plantar fasciitis is poor and that further investigation is needed. In addition, the limitation of the success of using orthotics may be because Orthotics can only be used in conjunction with shoes. Many people may not wear shoes when at home, meaning the Orthotics are not being used during this time. The feet are therefore unsupported for a significant number of hours when weight-bearing (walking and standing) without shoes. This research, therefore, involves testing the addition of contoured comfort sandals with built-in arch support that can be worn while at home, as well as the Orthotics which will be worn during the day with shoes. Contemporaneous research on Orthotics is limited to only using Orthotics and there are no studies that use both the Orthotics and comfort sandal.

This is a randomised control trial that will be conducted over a 6-month period, during which participants will be asked to provide data in the form of completed surveys at 5 points throughout the study period. The aim of the study is to investigate whether the use of prefabricated Orthotics in shoes, in combination with the use of indoor comfort sandals with built-in arch support, benefits the treatment of plantar fasciitis more than the sole use of prefabricated Orthotics in shoes alone.

The study population will include 104 participants who will be randomised into a study and control group. Participants in the study group will be asked to insert the Orthotics into normal footwear and to use them wherever possible. Participants will also be instructed to use the comfort sandal with built-in arch support when not using shoes whilst at home. Participants in group B will only be asked to use the Orthotic inserted into daily footwear wherever suitable (i.e. when outside of the home). Participants from both groups will be asked to continue with normal activities throughout the study period.

During the 6 month study period, all participants will be asked to complete and submit surveys at baseline, 3 weeks, 6 weeks, 3 months and 6 months from entry into the study. ;
