- Brief 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.
- Detailed 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.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 104
- Have been experiencing symptoms of Plantar Fasciitis for at least 2 months. A diagnosis of plantar fasciitis will be made on the criteria that the pain is located on the medial aspect of the heel on palpation and the pain is worst the first thing in the morning.
- Aged 19-75 years old
- Prior operations on the foot,
- Prior treatments apart from analgesia in the last 12 months e.g. corticosteroid injections,
- Congenital or acquired foot and ankle abnormalities which prevent the use of normal footwear.

Group Intervention Description Prefabricated Orthotics in shoes & indoor comfort sandals with built-in arch support Aetrex L420 Compete Orthotic Participants from Group A will receive an L400 Compete Orthotic (https://www.aetrex.com/search?q=l420\&search-button=\&lang=en_US) and an Aetrex comfort sandal with built-in arch support (https://www.aetrex.com/aetrex-flips-black-L3000M.html?lang=en_US or https://www.aetrex.com/fiji-flips-women-watermelon-L7009W.html?lang=en_US) according to participants shoe size. The investigators will send an instruction sheet along with the Orthotic in the post, explaining how to use it. Alternatively, an online video tutorial on how to use the Orthotic will also be available throughout the study. The group will be asked to continue with usual activities, using the orthotic/comfort sandal wherever possible.

Prefabricated Orthotics in shoes only Aetrex L420 Compete Orthotic Group B will receive an L400 Compete Orthotic (https://www.aetrex.com/search?q=l420\&search-button=\&lang=en_US) alone. The investigators will send an instruction sheet along with the Orthotic in the post, explaining how to use it. Alternatively, an online video tutorial on how to use the Orthotic will also be available throughout the study. The group will be asked to continue with usual activities, using the Orthotic wherever possible.
- Primary Outcome Measures
Name Time Method Changes in Pain as assessed by a Visual Analogue Scale (VAS) Baseline, 3 weeks, 6 weeks, 3 months and 6 months Pain will be collected on via a self-report Visual Analogue Scale (VAS) as follows: 0 to 10 where 0 is 'No Pain' and 10 is 'The worst imaginable pain'.
- Secondary Outcome Measures
Name Time Method Changes in Foot health status as assessed by the Foot Health Status Questionnaire (FHSQ) Baseline, 3 weeks, 6 weeks, 3 months and 6 months Foot Pain \& Functionality scores will be collected using the FHSQ or Foot Health Status Questionnaire. The Foot Health Status Questionnaire is designed to assess foot pain, foot health and its relation to quality of life. The questionnaire has four domains consisting of 13 key items. The four domains are; foot pain, foot function, footwear and general foot health. The current study will only use the 2 subsections of Foot Pain and Foot Function. In these subsections, participants will be required to rate foot pain in the last week from 1 (none) to 5 (severe), how often the participant experienced different types of foot pain during the last week from 1 (never) to 5 (always), how much the participants feet interfered with everyday activities in the last week from 1 (not at all) to 5 (extremely) and overall foot health from 1 (excellent) to 5 (poor). Previous research has found the FHSQ to exhibit a strong degree of context, criterion and construct validity with high retest reliability.
Changes in overall health as assessed by The Global Rating Scale of Change (GROC scale) Baseline, 3 weeks, 6 weeks, 3 months and 6 months The Global Rating Scale of Change, or the GROC scale, will be used in the current study to assess participants overall health. This will give further insight into the effectiveness of the interventions. It is an 11 point scale from -5 to + 5. "-5" denotes "very much worse", "0" denotes "unchanged" and "+5" denotes "completely recovered".
