Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Provision of six weeks supervised hand therapy, followed by four weeks of home-based hand therapy. The participants are provided with 30 minutes of therapeutic exercises, and 30 minutes of occupation based intervention in one therapy session, twice a week during the six weeks of supervised hand therapy. In addition, all participants are provided with paraffin bath treatment to prepare the injured hands for active mobilisation. The therapeutic exercises used are similar to the control group. Occupation based intervention consists of three selected occupational tasks; picking up small everyday objects, washing/wiping dishes and typing on a keyboard. The occupational tasks were chosen based on the therapeutic benefits that were described by Malaysian occupational therapists in an unpublished study by the investigator. All the therapy sessions are administered by an occupational therapist. The intervention is then followed by four weeks of home-based hand therapy, two hours per week for four weeks. The participants are asked to incorporate these tasks into their occupations for daily living. For instance, they are asked to wash/wipe dishes after a meal, type any tasks using the keyboard (homework/office work/ replying to emails/chatting) and pick up everyday small objects that related to their day to day activities. All participants are provided with a checklist diary to remind them to complete the program.

Rehabilitation
Comparator / control treatment
Similarly to the intervention group, the participants in the control group are provided with six weeks of supervised hand therapy, followed by four weeks of home-based hand therapy. During the six weeks of supervised hand therapy, the participants are only provided with 60 minutes of therapeutic exercises in one session, twice a week, after the application of paraffin bath. The therapeutic exercises used are range of motion (ROM) exercises (passive, active assisted and active) and strengthening activities. ROM and strengthening modalities such as theraputty, digiflex and hand helper are concurrently used during the therapy session. The participants are gradually taught how to carry out the therapeutic exercises at home during the six weeks of supervised hand therapy. Therapeutic exercise modalities are provided to each participant for the purpose of home-based hand therapy. They are required to complete two hours of these tasks per week, for four weeks, as part of their home program treatment. All participants are provided with a checklist diary to remind them to complete the program.

Outcomes
Primary outcome [1] 292188 0
Disability/symptom following hand injuries is measured by using the Disability of Arm, Shoulder and Hand (DASH). An English and Malay version of DASH is used in the study according to the participants’ preference. The participant is asked to complete the DASH questionnaire at the end of each evaluation session.

Total Active Motion (TAM) is measured by using a finger goniometer while the wrist is in the neutral position and the forearm is pronated. Each joint of the digits and thumb is measured individually. The sum of all active flexion measurements of digits joints (MCP, PIP and DIP) and thumb joints (MCP, IP ) is calculated and the sum of all extension deficits of the digits and thumb is subtracted from it, to compute the TAM.

Fine and gross dexterity are measured by using the Perdue Pegboard test. The test has five subtests; Right Hand (RH); Left Hand (LH), Both Hands (BH); Right+Left+Both (RLBH) and; Assembly. Three measurements are taken for each subtest and the average is calculated. The test is conducted according to the manual booklet of Purdue pegboard test model 32020.

Grip strength is measured by using a Jamar hand dynamometer.The participants are instructed to sit with shoulder adducted and neutrally rotated, elbow flexed at 90 degree, forearm in neutral position and wrist between 0 to 30 degree extension. The grasp setting is set at the second level to give maximal contraction and allow for full function of profundus, superficialis and interossoues muscles. Three measurements are taken from each participant and the average is calculated for the analysis.

Secondary outcome [4] 308419 0
Pinch strength is measured by using a B&L pinch gauge. The position of the participant is similar to that used in measuring grip strength. Key pinch is selected to measure pinch strength because it is the strongest type of pinch and easier to test. Key pinch is also known as lateral pinch; it is tested when the pinch gauge is positioned between the pad of the thumb and the radial side of middle phalanx of the index finger. As for grip strength, the test is repeated for three trials, and the average is calculated for the analysis.

Secondary outcome [5] 308420 0
Occupational performance and satisfaction with the occupational performance are assessed by using the Canadian Occupational Performance Measure (COPM). The participants are interviewed to identify the five most important occupational performance issues that impacted on their life following the hand injury. A scale of 1 to 10 is used, where 10 is the most important goal needed to be attained by the participants. Using the same scale, the participants are asked to rate the performance of the occupations and satisfaction with their performance. Both the sum of performance and satisfaction scores are divided by the number of identified problems to compute the overall score for analysis.

Secondary outcome [6] 308421 0
Neuropathic pain following hand injury is measured using the Graphic Numerical Rating Scale (GNRS), where zero indicates no pain and 10 indicates the worst pain possible. The participants are asked to circle the number representing their level of pain on a graphic scale.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A research assistant screens the eligible clients, and offers an opportunity to participate in the study. Verbal and written information about the study are given to the clients, and consent is obtained from the participants who agreed to take part in the study. The participants who consent to take part in the study are randomly allocated into the intervention (OBI) group and the control (TE) group using a random number table, which is prepared in advanced before the enrollment of the first participant. One large permuted-block method are used to balance the number of participants in the OBI and TE group. The assistant is also responsible to allocate the participants consecutively into either to the OBI or TE group by using the random number table. Allocation to the groups is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The random number table was generated via http://www.random.org/sequences/?min=1&max=46&col=2&format=html&rnd=new.

Efficacy
Statistical methods / analysis
The power analysis is calculated based on the findings from a comparable study (Guzelkucuk et al., 2007). Thirty-eight participants are required to detect a significant group difference (p<.05) of 15 DASH score with 80% power. Assuming a maximum 20% drop-out rate as suggested in a recent systematic review, it follows that 46 participants are needed for the study.

All data are statistically analysed using the Statistical Package for Social Sciences (SPSS) version 22.0 for windows. Tests included t-test, chi-square and fisher’s exact test to determine whether differences existed between groups for participants’ characteristics. Three sets of t-tests are also used to compare the groups at baseline, post six weeks of supervised hand therapy and post four weeks of home-based hand therapy. Possible confounding effects which might have influenced therapeutic outcomes are examined using linear mixed models. It also allows the researcher to examine whether the effect of treatment varied among classes of participants. The participants’ characteristics such as age, sex, duration of injury, injured hand, cause of injury, number of digit affected, occupation and type of injury are each treated as fixed effects to determine whether they influenced therapeutic outcomes, using individual subject as a random effect. The statistical significant level is set at p < 0.05 (two-tailed).
