Description of intervention(s) / exposure
A 12 week multi-faceted podiatry treatment consisting of foot orthotics; foot and ankle exercises performed both in the clinic and on a daily basis at home; and education and advice concerning appropriate footwear, analgesia, weight management and general physical activity. These are explained in more detail below:

Foot orthotics: prefabricated device with (a) a first ray cut out unless pain is exacerbated, or (b) a morton's extension if pain is exacerbated with the cut out. People with a FPI score >7 will also have a varus wedge added. After a familiarisation period, participants will be advised to wear their orthotics as much as possible each day, however at a minimmum, they will be advised to wear them for at least 6 hours every day.
Exercises: Performed twice daily for an approximate duration of 20 minutes each, and including (a) Isometric flexor hallucis strengthening (push toe in to ground) performed 10 x 10 seconds, (b) mobilisation performed by first metatarsophalangeal joint distraction (one minute) and glides (one minute), (c) plantar foot massage using a ball for 5 minutes
Advice delivered by the podiatrist during each participant's initial clinical visit (approx 10 minutes). This will include advice on analgesia (a maximum of 4 g/day of paracetamol if needed), weight management (general advice and dietitian referral if needed) and physical activity (30 minutes on most days) will be provided and reinforced with an Arthritis Australia booklet).

Treatment adherence will be self-assessed in a log book and participants will be sent reminder emails by a research assistant.

Eligibility
Key inclusion criteria
Participants aged over 40 with symptomatic radiographic first metatarsophalangeal joint osteoarthritis. First metatarsophalangeal joint osteoarthritis will be defined as radiographic osteoarthritis (established using a valid and reliable atlas) and corresponding self-reported pain of >40mm on a 100mm visual analogue scale in the past four weeks in one or both of the first metatarsophalangeal joints.
Minimum age
40 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
The main exclusion criteria are:

(ii) use of foot orthotics or intra-articular foot injections in the past six months
(iii) previous musculoskeletal foot surgery;
(iv) grade 3 or 4 hallux valgus;
(v) currently receiving treatment for their first metatarsophalangeal joint osteoarthritis pain;
(vi) medial knee OA or pain; and
(vii) pain in any other location that is worse that their first metatarsophalangeal joint osteoarthritis pain.

Efficacy
Statistical methods / analysis
This is a proof of concept study designed to generate important feasibility, safety and efficacy data to be used to inform a future large randomised controlled trial. Using confidence intervals to help determine samples size for pilot studies, samples between 10-15 have been suggested to be adequate. Thus we have selected a sample size of 15 individuals per group, or 30 participants in total.

Analysis of covariance (ANCOVA) will be used to compare the effect of each treatment over time (pre/post) on pain and functional outcome measures, with group allocation as the fixed factor and corresponding baseline outcome values as covariates. Alpha will be set at 0.05.
