Study type
Interventional
Description of intervention(s) / exposure
A cross-over randomised controlled trial design will be used with the interventions being: (a) use of electric gloves, or (b) routine practice each for 4 weeks with 1 week ‘washout’ between study periods. The trial will take place during the Adelaide winter months of July to Sept. It will not be blinded. Rheumatologists working in a dedicated Systemic Sclerosis clinic will recruit and administer the trial.
Participants can choose any of three settings designated low (38ºC), medium (47 ºC), or high (55ºC). The gloves have slimline rechargeable batteries and provide >5 hours heat on the lowest setting. This is a pragmatic trial and participants will choose the frequency and duration of time wearing the gloves. They will keep a daily Raynaud’s Attack Diary which will record the number of attacks, the duration of each and whether or not gloves were worn during an attack. Participants will also complete a Raynaud’s Condition Score which asks the extent of difficulty with Raynaud’s each day.

Treatment: Devices
Comparator / control treatment
The participant's usual practice, which may involve gloves (not heated). This will be a 4-week period. No specific instructions eg avoidance of heated hand warmers will be made as this is a pragmatic trial.

Active

Outcomes
Primary outcome [1] 327342 0
Raynaud’s Condition Score (RCS)
Timepoint [1] 327342 0
Recorded daily for 4 weeks post commencement of treatment period.
Secondary outcome [1] 394648 0
The Raynaud’s Attack diary provides a measure of the frequency and duration of Raynaud’s attacks. This has been used in clinical drug trials and these reports supply the means and Standard Deviations for number and duration of attacks. It will also record whether or not the heated gloves were being worn at the time of an attack.
There will also be a measure of satisfaction with wearing the gloves and the question “Do you intend to continue wearing the gloves after the trial?”
Timepoint [1] 394648 0
Recorded daily for 4 weeks post commencement of treatment period.

Eligibility

Efficacy
Statistical methods / analysis
Baseline characteristics will be analysed descriptively (using means and standard deviations or medians and interquartile ranges for continuous variables; and using frequencies and percentages for categorical variables).
Paired Students’ T-test will be used to determine the difference in means between the two treatment groups.
Secondary and exploratory outcomes will be analysed descriptively and also by using logistic and linear regression models, as appropriate.
For all outcomes, statistical significance will be assessed at the 0.05 level (two-sided). In addition to effect estimates and p-values, 95% confidence intervals will be reported to express uncertainty about the estimated effects.
