Clinical Trial Summary

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.

Intervention

Device:
• Foot orthoses
Manufacturer: Foot Science International. Material: High grade thermoformable closed-cell polyolefin foam (medium density) Arch support: inbuilt. Covering: fabric Provided by: Study Practitioner: Registered physiotherapist > 2 years musculoskeletal experience will be trained to prescribe the insert according to the prescription algorithm. Where: Administered via telehealth When and how much: Week 0 to 1: one telehealth session with study practitioner to fit one pair of pre-fabricated orthoses Week 1 to 2: Follow-up session for questions if required Tailoring: Orthoses are fit to comfort. Lengths (S, S, M, L, XL, XXL) (dependent on participant's shoe size). Hardness = Medium density. Modifications: can be cut to size to assist in fit using the shoes original sock liner as a guide, by participants using standard scissors. Heat molding: optional. Adherence: Adherence recorded with diary/ log book (insert wear time)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility: adherence	Recruitment rate (average 1 participant per week); 50% log-book completion rate (daily); drop-out <20%; 35 hours per week adherence to intervention (log book)	6 weeks
Secondary	Hip-related pain	Hip osteoarthritis outcome score: pain sub-scale (HOOS-12). Scores range for 0 (better outcomes) - 100 (worse outcomes)	Baseline and 6 weeks
Secondary	Hip-related physical function	Hip osteoarthritis outcome score: function and daily living subscale. Scores range for 0 (better outcomes) - 100 (worse outcomes)	Baseline and 6 weeks
Secondary	Hip-related quality of life	hip osteoarthritis outcome score: quality of life subscale: Scores range for 0 (better outcomes) - 100 (worse outcomes)	Baseline and 6 weeks
Secondary	Fear of movement	Brief Fear of Movement Scale for osteoarthritis (BFOM); 0 to 24, with a higher score indicating lower fear of movement (better score)	Baseline and 6 weeks
Secondary	Depressive symptoms	Patient Health Questionnaire -9: Scored from 0 to 27, participants can be classified as having mild (= 5), moderate (= 10), moderately severe (= 15) and severe (= 20) depressive symptoms.	Baseline and 6 weeks
Secondary	Physical activity- Self-reported	The International Physical Activity Questionnaire: Participants will be asked to recall their physical activity over the last 7 days with regard to vigorous physical activity, moderate physical activity, walking and sitting.	Baseline and 6 weeks
Secondary	Physical activity- Walking based physical activity	Will be measured with a tri-axial accelerometer-based activity monitor that is attached on the thigh (activPAL model 4 micro; PAL Technologies Ltd, Glasgow, UK) and will be expressed as a) daily minutes of moderate and vigorous physical activity using the established 100 steps/minute threshold and b) total daily steps (which captures both inside and outside the home walking activity).	Baseline and 6 weeks
Secondary	Global rating of change- Physical activity	Seven point rating scale. Much better, better, a little better, no change, a little worse, worse, much worse	Week 6
Secondary	Global rating of change- Symptoms	Seven point rating scale. Much better, better, a little better, no change, a little worse, worse, much worse	Week 6
