About this trial
This randomized controlled study aims to compare the effects of three different wrist positions (30° extension, neutral, and 30° flexion) used in dorsal blocking orthoses during early active mobilization after zone I-II flexor tendon repair. A total of 54 patients will be randomly assigned into three groups. All participants will receive the same rehabilitation protocol. Clinical and functional outcomes including total active motion, pain, complications, functional status, and orthosis satisfaction will be evaluated at 6, 8, and 12 weeks by a blinded assessor.

Referral to physiotherapy within the first 10 days after surgery
Eligibility for a controlled early active mobilization protocol
Disqualifiers

Treatments tested in this trial
3D-Printed Dorsal Blocking Orthosis (wrist 30 degree extension)
DeviceParticipants will use a 3D-printed dorsal blocking orthosis with the wrist positioned at 30° extension and follow a controlled early active mobilization protocol.
3D-Printed Dorsal Blocking Orthosis (wrist neutral)
DeviceParticipants will use a 3D-printed dorsal blocking orthosis with the wrist in neutral position and follow the same rehabilitation protocol.
3D-Printed Dorsal Blocking Orthosis (wrist 30 degree flexion)
DeviceParticipants will use a 3D-printed dorsal blocking orthosis with the wrist positioned at 30° flexion and follow the same rehabilitation protocol.
Treatment groups
Trial outcomes
Primary outcomes
Total Active Motion (TAM)
Total active motion will be calculated by summing the active flexion angles of the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints and subtracting any extension deficits. Measurements will be performed using a finger goniometer and evaluated according to the Buck-Gramcko classification.
Secondary outcomes
Pain Intensity
Pain intensity will be assessed using a Numeric Rating Scale (NRS) ranging from 0 (no pain) to 10 (worst possible pain).
Hand Function
Hand function will be evaluated using the Jebsen-Taylor Hand Function Test, which measures the time required to complete standardized hand tasks.
Upper Extremity Function
Upper extremity functional status will be assessed using the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire. Lower scores indicate better function.
Grip Strength
Grip strength will be measured using a hydraulic hand dynamometer and recorded in kilograms.
