• Change from first evaluation on the Michigan Hand Questionnaire at 2, 3 and 6 months [ Time Frame: 0-3 days, 2 months, 3 months and 6 months after surgery ]
  Patient-reported questionnaire that evaluates function and quality of life in patients with hand disorders. There are 37 items divided into 6 subscales (1)overall hand function, (2)activities of daily living, (3)pain, (4)work performance, (5)aesthetics and (6)patient's satisfaction with hand function). (Total score between 0-100, rating scale from 1 to 5)
• Change from first evaluation on the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) outcome measure at 2, 3 and 6 months [ Time Frame: 0-3 days, 2 months, 3 months and 6 months after surgery ]
  Patient-reported questionnaire that evaluates 11 items on symptoms and functional impairments related to musculoskeletal disorders of the upper limb. (Total score between 0-100, rating scale from 1 to 5)
• Change from first evaluation on the Sollerman Test at 2, 3 and 6 months [ Time Frame: 2 months and 6 months after surgery ]
  A standardized hand function assessment based on seven of the eight most common hand grips that consists of 20 activities of daily living. (Total score between 0-80, rating scale 0 to 4).

• Range of motion assessed by Rolyan digital goniometer [ Time Frame: 0-3 days, 2 months, 3 months and 6 months after surgery ]
  Range of motion of the affected digits assessed by Rolyan digital goniometer (data scope -30° to 120°, accuracy of 2°)
• Pain measured using the Visual Analogue Scale [ Time Frame: 0-3 days, 2 months, 3 months and 6 months after surgery ]
  Responders specify their level of pain by indicating a position along a continuous line between two end-points. One end (corresponding to score 0) represents the absence of pain, and the other end (corresponding to score 100) represents the worst pain that the person can imagine. (Thus the minimum score is 0, and the maximum score is 100. There are no sub-scales. 0 represents the absence of pain, and higher values represent more pain.)
• Grip strength [ Time Frame: 2 months, 3 months and 6 months after surgery ]
  JAMAR dynamometer (data scope 0-80 kg, accuracy of 2 kg)
• Pinch strength [ Time Frame: 2 months, 3 months and 6 months after surgery ]
  B&L pinch gauge (data scope 0-30 pounds, accuracy of 1 pound)
• Tactile sensibility [ Time Frame: 2 months, 3 months and 6 months after surgery ]

Dupuytren's disease can cause physical impairments that lead to reduced functional performance in personal care, work-related and leisure activities. The prevalence of Dupuytren's disease increases with age. A meta-analysis completed in 2014 by Lanting and al. estimated the its prevalence in western countries at 12% among people aged 55 years and over and at 29% among individuals aged 75 and over. The fasciectomy is the most current surgical procedure to reduce the flexion contracture occurring in this disease. Studies confirm the relevance of post-operative rehabilitation after fasciectomy. This rehabilitation is usually conducted by hand therapists who are mostly occupational therapists. However, the required duration and frequency of interventions and exercises for the post-op rehabilitation are not clearly described in the literature. In fact, the guidelines that are currently available recommend a total duration between 16 and 75 hours, which is highly variable. Also, the need to include supervised exercises by the occupational therapist is not specified. The main goal of this study is to compare two post-fasciectomy rehabilitation protocols to determine the influence of protocols intensity on motor and functional outcomes in people with Dupuytren's disease. The hypothesis is that the protocol involving a higher intensity will lead to better motor and functional improvements. The secondary goal of this study is to explore the link between the total time that the person has done the recommended exercises (combination of supervised exercises and the home program) and motor/functional recovery. The hypothesis is that the relationship between the amount of time and the motor/functional improvements will not be linear, but will either be logarithmic toward a plateau of recovery.

A randomized controlled trial will be realized. 40 participants will be randomly assigned to one of the two rehabilitation protocols. Each participant will be evaluated at four times (initial evaluation, final evaluation and 2 follow-up evaluations). Data on motor and functional recovery will be collected.

A randomized controlled trial will be realized. 40 participants will be randomly assigned to one of the two rehabilitation protocols. Each participant will be evaluated at four times (initial evaluation, final evaluation and 2 follow-up evaluations). The independent variable of this study is the intensity of the rehabilitation protocol (BRIEF or INTENSE). The primary dependent variable is the functional abilities to perform activities of daily living. The secondary dependent variables are the following : digits range of motion, pain, grip and pinch strengths, as well as tactile sensibility.

The BRIEF PROTOCOL consists of 4 intervention sessions with an occupational therapist specialized in hand therapy that will occur at 0-3 days, 2 weeks, 4 weeks and 8 weeks post-fasciectomy. The occupational therapist will give recommendations about the management of swelling, wound care and functional recovery. An home exercises program will be given to the participant. Finally, an extension splint that must be worn at night until the third month after surgery will be made at the first session. The INTENSE PROTOCOL consists of 6 intervention sessions with an occupational therapist specialized in hand therapy that will occur at 0-3 days, 2 weeks, 3 weeks, 4 weeks, 6 weeks and 8 weeks after surgery. The occupational therapist will give recommendations about the management of swelling, wound care and functional recovery. An home exercises program will be given to the participant. An extension splint that must be worn at night until the third month after surgery will be made at the first session. Also, exercises will be performed by the patient under the supervision of the occupational therapist (supervised exercises) in each session except the first one at 0-3 days after surgery.

Statistical analyses will take into account the moderate size of our sample (n=40) and the independence of the two groups. Descriptive statistics and Shapiro-Wilk test will be used to evaluate if variables follow the normal distribution. If the normal distribution is confirmed, repeated measure ANOVA will be used to compare the 2 groups. If not, Mann-Whitney test will be used (non-parametric test). Pearson correlation coefficient (parametric) or Spearman correlation coefficient (non-parametric) will be used to analyze the relationships between variables (secondary aim of the study).
