Hip Osteoarthritis and Foot Orthoses Trial (HOOT)

Overview

This trial is a randomized feasibility trial to determine the feasibility of comparing two different shoe inserts and on pain, quality of life and physical activity associated with hip osteoarthritis.

Description

Participants will be randomized to one of two groups - contoured prefabricated foot orthoses or flat shoe inserts (the comparator). Participants will be asked to use the inserts daily for a six week period. Adherence to the intervention will be monitored using a daily diary, as well as adverse events and co-interventions. The primary outcome is feasibility domains (Demand, Implementation, Acceptability, Practicality) with secondary outcomes of change in hip-related pain and quality of life and physical activity levels. The primary time-point will be 6-weeks.
