Measurement of ankle joint dorsiflexion is routinely undertaken by clinicians who manage lower limb musculoskeletal pathology. This study aimed to determine the reliability of a technique to measure ankle joint dorsiflexion in a weightbearing position with the knee extended. Four raters with varying clinical experience measured ankle joint dorsiflexion in a(More)
OBJECTIVE To develop a radiographic atlas for the classification of osteoarthritis (OA) in commonly affected joints of the foot based on observations of osteophytes and joint space narrowing, and to assess its intra- and inter-examiner reliability. DESIGN Weightbearing dorso-plantar and lateral foot radiographs from people aged over 65 years were(More)
INTRODUCTION Plantar heel pain causes soreness or tenderness of the sole of the foot under the heel, which sometimes extends into the medial arch. The prevalence and prognosis are unclear, but the symptoms seem to resolve over time in most people. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical question:(More)
This research project investigated the orthotic prescription habits of podiatric physicians in Australia and New Zealand. A 23-item questionnaire was distributed to all members of the Australian Podiatry Association and the New Zealand Society of Podiatrists. When asked what type of foot orthoses they prescribe most often, 72% of respondents reported(More)
BACKGROUND One of the hypothesised mechanisms by which foot orthoses obtain their clinical effect is by influencing muscle activity, however previous studies have reported highly variable findings. The aim of this study was to determine whether orthoses change muscle activity in people with flat-arched feet towards a pattern observed in people with(More)
BACKGROUND Foot orthoses have been demonstrated to be effective in the management of a range of conditions, but there is debate as to the benefits of customised foot orthoses over less expensive, prefabricated devices. METHODS In a randomised, cross-over trial, 15 flat-footed participants aged between 18 and 45 years were provided with semi-rigid,(More)
The chevron and scarf osteotomies are commonly used for the surgical management of hallux valgus (HV). However, there is debate as to whether one osteotomy provides more 1-2 intermetatarsal (1-2 IMA) correction than the other. The objective of this systematic review and meta-analysis was to compare the effectiveness of 3 types of first metatarsal osteotomy(More)
BACKGROUND There are several clinical and radiological methods available to classify foot posture in research, however there is no clear strategy for selecting the most appropriate measurements. Therefore, the aim of this study was to develop a foot screening protocol to distinguish between participants with normal- and flat-arched feet who would then(More)
BACKGROUND Some studies have found that flat-arched foot posture is related to altered lower limb muscle function compared to normal- or high-arched feet. However, the results from these studies were based on highly selected populations such as those with rheumatoid arthritis. Therefore, the objective of this study was to compare lower limb muscle function(More)
