Study type
Interventional
Description of intervention(s) / exposure
The treatment product is a topical 4% w/w Cannabidiol gel that is applied 3 times per day over a four week period to joints of the hand suffering painful arthritis. The product is supplied in a metered pump that administers 0.25 ml. Subjects will be instructed to apply a single 0.25 ml pump to the affected hand at each application. The gel will then be massaged into the joints of the hand affected by arthritis.

Subjects will complete a questionnaire each night via their smart-phone, that will ask them to confirm that they have adhered to the application instructions that day as described by the protocol.

Outcomes
Primary outcome [1] 328892 0
Changes in hand pain as assessed by the Numeric Pain Rating Scale (NPRS)
Timepoint [1] 328892 0
Pain scores will be recorded on a daily basis during week 1 to calculate baseline pain scores. Pain scores will be recorded on a daily basis from weeks 2-5 to accompany the 4 week dosing period. The primary outcome will compare pain scores 4 weeks post commencement with those obtained at baseline to determine whether the treatment has had any effect..
Secondary outcome [1] 400812 0
Changes in grip strength as assessed by a squeeze ball dynamometer connected via Bluetooth to a recording app
Timepoint [1] 400812 0
Grip strength will be recorded on a daily basis during week 1 to calculate baseline scores. Grip strength will be recorded on a daily basis from weeks 2-5 to accompany the 4 week dosing period. The secondary outcome will compare grip strength scores 4 weeks post commencement with those obtained at baseline to determine whether the treatment has had any effect..
Secondary outcome [2] 401565 0
Changes in hand functionality as measured by the Functional Index for Hand OsteoArthritis (FIHOA) score.
Timepoint [2] 401565 0
FIHOA scores will be recorded on a weekly basis. FIHOA scores at 4 weeks will be compared with those recorded at Baseline..
