Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A small container of medical grade silicone oil (dimethyl silicone fluid) with a viscosity of 350 centistokes is used to immerse the operated hand into for 20 minutes while a series of finger exercises are completed. The intervention commences on day 3 after finger contracture release surgery and terminates at 14 days post surgery when wound healing is achieved. The exercises are taught at the first visit in a single 45 minute session with the physiotherapist. The patient is instructed to make a full fist as able, hold, then slowly straighten the fingers. Repeat this slowly for 10 repetitions, then rest for 2 minutes. Repeat the above routine 4 times, during the total immersion period of 20 minutes once daily. The patient will have the container of oil at home with them.
The patient will complete a treatment diary to monitor the intervention.

Comparator / control treatment
The active control group will perform the same protocol of exercises for 20 minutes per day, from day 3-14 post-operatively at home without using an immersion medium.
This treatment constitutes usual care.

Outcomes
Primary outcome [1] 295095 0
Physiotherapy delivery of intervention assessed using a SEGUE score.
Timepoint [1] 295095 0
Timepoint:Day 3 post surgery.
Primary outcome [2] 295096 0
Patient receipt and enactment of intervention assessed by
number of finger flexions completed within the 20 minute exercise period. This composite outcome involves (a) an independent researcher making one video recording of each participant completing their exercises at home and (b) a daily self recorded treatment diary by the patient.
Timepoint [2] 295096 0
Daily diary from day 3 to day 14 post-operatively with one video recording occurring between days 3-14.
Primary outcome [3] 295097 0
Patient acceptability of the intervention assessed using CSQ8 survey and focus group discussion.
Timepoint [3] 295097 0
3 months after surgery
Secondary outcome [1] 314762 0
Health related quality of life questionnaire, The Michigan Hand Outcome Questionnaire (MHOQ) and URAM.
Timepoint [1] 314762 0
Baseline ie pre-operatively and final outcome 3 months after surgery.
Secondary outcome [2] 314763 0
Range of motion and measurement of fixed flexion deformities in the affected fingers will be done using goniometry.
Timepoint [2] 314763 0
Measured on four occasions:
baseline (1 week pre-operatively) with repeated measures taken at three and fourteen days post-operatively, and the final outcome at twelve weeks after surgery.
Secondary outcome [3] 315115 0
Level of pain while completing 20 minutes of finger exercises assessedusing numerical pain rating scale (NPRS).
Timepoint [3] 315115 0
Daily from days 3 -14.
Secondary outcome [4] 315116 0
Level of difficulty completing intervention assessed using a Likert scale
where 0 = Easy, 5= someone helped me a little, 10= needed another person to change my wound dressings.
Timepoint [4] 315116 0
Daily from day 3-14 post operatively.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will provided with a written information sheet and have an opportunity to ask questions at a pre-operative appointment. Written informed consent documents will be completed at this point to enroll a participant into the study. The assessment will be conducted at the physiotherapy clinic in the week prior to the patients scheduled surgery.The physiotherapy practice receptionist will allocate participants to either Group I or Group II when they phone to book their first appointment. Allocation to the two groups - Group I (usual care-without SO) or Group II ( usual care with SO) will be carried out by the receptionist whereby the sequentially numbered sealed envelopes will determine which arm of the study the participant enters into.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequentially numbered sealed envelopes will be used that contain the allocation sequence generated from the website Randomisation.com.

Statistical methods / analysis
Base line demographics and characteristics of participants will be analyzed with descriptive statistics. The mean SEGUE scores will be compared between study Group I and Group II to evaluate the degree of uniformity in delivery of both interventions using independent t-tests.
How receptive the patient is to the intervention will be assessed using the numerical rating scale for pain, and the Likert scale for level of difficulty. A comparison between the intervention groups I and II will be made using independent t-tests to identify if the SO intervention was thought to be significantly more difficult, or painful, from the patient perspective. Enactment will be measured by comparing patient diaries with the protocol for daily exercises and number of minutes spent in oil for variances from the protocol. The number of finger flexion and extensions will be counts from video footage compared to the number specified in the protocol and will be analyzed using a t-test.
Acceptability of Intervention from the patient perspective will be determined by the satisfaction survey CSQ-8. Independent t tests between the 2 study groups will be performed to identify if a significant difference exists. Free text from the open ended questions will be analyzed by grouping the data into clusters and themes then classified by frequencies. Qualitative data collected from the focus group will be analyzed using the same method. Quality of life questionnaires (MHOQ and URAM) will be analyzed using t tests.
