Effects of metatarsal domes on plantar pressures in older people with a history of forefoot pain.

ABSTRACT: BACKGROUND:Forefoot pads such as metatarsal domes are commonly used in clinical practice for the treatment of pressure-related forefoot pain, however evidence for their effects is inconsistent. This study aimed to evaluate the effects on plantar pressures of metatarsal domes in different positions relative to the metatarsal heads. METHODS:Participants in this study included 36 community-dwelling adults aged 65 or older with a history of forefoot pain. Standardised footwear was used and plantar pressures were measured using the pedar®-X in-shoe plantar pressure measurement system. Peak pressure, maximum force and contact area were analysed using an anatomically-based masking protocol that included three forefoot mask sub-areas (proximal to, beneath, and distal to the metatarsal heads). Data were collected for two different types of prefabricated metatarsal domes of different densities (Emsold metatarsal dome and Langer PPT metatarsal pad) in three different positions relative to the metatarsal heads. Seven conditions were tested in this study: (i) control (no pad) condition, (ii) Emsold metatarsal dome positioned 5?mm proximal to the metatarsal heads, (iii) Emsold metatarsal dome positioned in-line with the metatarsal heads, (iv), Emsold metatarsal dome positioned 5?mm distal to the metatarsal heads, (v) Langer PPT metatarsal pad positioned 5?mm proximal to the metatarsal heads, (vi) Langer PPT metatarsal pad positioned in-line with the metatarsal heads, and (vii) Langer PPT metatarsal pad positioned 5?mm distal to the metatarsal heads. RESULTS:When analysed with the mask that was distal to the metatarsal heads, where the plantar pressure readings were at their highest, all metatarsal dome conditions led to significant reductions in plantar pressure at the forefoot compared to the control (no pad) condition (F3.9, 135.6?=?8.125, p?

Project description:BACKGROUND:In people with diabetes, offloading high-risk foot regions by optimising footwear, or insoles, may prevent ulceration. This systematic review aimed to summarise and evaluate the evidence for footwear and insole features that reduce pathological plantar pressures and the occurrence of diabetic neuropathy ulceration at the plantar forefoot in people with diabetic neuropathy. METHODS:Six electronic databases (Medline, Cinahl, Amed, Proquest, Scopus, Academic Search Premier) were searched in July 2019. The search period was from 1987 to July 2019. Articles, in English, using footwear or insoles as interventions in patients with diabetic neuropathy were reviewed. Any study design was eligible for inclusion except systematic literature reviews and case reports. Search terms were diabetic foot, physiopathology, foot deformities, neuropath*, footwear, orthoses, shoe, footwear prescription, insole, sock*, ulcer prevention, offloading, foot ulcer, plantar pressure. RESULTS:Twenty-five studies were reviewed. The included articles used repeated measure (n?=?12), case-control (n?=?3), prospective cohort (n?=?2), randomised crossover (n?=?1), and randomised controlled trial (RCT) (n?=?7) designs. This involved a total of 2063 participants. Eleven studies investigated footwear, and 14 studies investigated insoles as an intervention. Six studies investigated ulcer recurrence; no study investigated the first occurrence of ulceration. The most commonly examined outcome measures were peak plantar pressure, pressure-time integral and total contact area. Methodological quality varied. Strong evidence existed for rocker soles to reduce peak plantar pressure. Moderate evidence existed for custom insoles to offload forefoot plantar pressure. There was weak evidence that insole contact area influenced plantar pressure. CONCLUSION:Rocker soles, custom-made insoles with metatarsal additions and a high degree of contact between the insole and foot reduce plantar pressures in a manner that may reduce ulcer occurrence. Most studies rely on reduction in plantar pressure measures as an outcome, rather than the occurrence of ulceration. There is limited evidence to inform footwear and insole interventions and prescription in this population. Further high-quality studies in this field are required.

Project description:BACKGROUND:Plantar heel pain is a common source of pain and disability. Evidence-based treatment decisions for people with plantar heel pain should be guided by the best available evidence, expert clinical reasoning, and consider the needs of the patient. Education is a key component of care for any patient and needs to be tailored to the patient and their condition. However, no previous work has identified, far less evaluated, the approaches and content required for optimal education for people with plantar heel pain. The aim of this study was to gather the patients' perspective regarding their lived experience, attitudes and educational needs in order to inform the content and provision of meaningful education delivery approaches. METHODS:Using a qualitative descriptive design, semi-structured interviews were conducted with participants with a clinical diagnosis of plantar heel pain. A topic guide was utilised that focused on the experience of living with plantar heel pain and attitudes regarding treatment and educational needs. Interviews were audio recorded, transcribed verbatim and analysed using the Framework approach. Each transcription, and the initial findings, were reported back to participants to invite respondent validation. RESULTS:Eighteen people with plantar heel pain were interviewed. Descriptive analysis revealed eight themes including perceptions of plantar heel pain, impact on self, dealing with plantar heel pain, source of information, patient needs, patient unmet needs, advice to others and interest in online education. Participants revealed doubt about the cause, treatment and prognosis of plantar heel pain. They also expressed a desire to have their pain eliminated and education individually tailored to their condition and needs. Respondent validation revealed that the transcripts were accurate, and participants were able to recognise their own experiences in the synthesised themes. CONCLUSION:Plantar heel pain has a negative impact on health-related quality of life. Participants wanted their pain eliminated and reported that their expectations and needs were frequently unmet. Health professionals have an important role to be responsive to the needs of the patient to improve their knowledge and influence pain and behaviour. Our study informs the content needed to help educate people with plantar heel pain.
