Patients in the kinesio taping group will receive KT application starting at postoperative week 6, after complete discontinuation of splint immobilization. During application, the functional correction technique will be used from the insertion to the origin of the Extensor Digitorum Communis (EDC) muscle, with approximately 25-50% tension applied to the tape. KT applications will be performed twice weekly between postoperative weeks 6 and 12, using three tapes in each session. New tapes will be applied in each session and replaced no later than 3 days after the previous application. Before each taping session, the application area will be properly cleaned. Additionally, patients and their caregivers will be thoroughly informed about hygiene of the application area and proper tape removal. The button-hole technique and I-strip technique will be used.

Patients in the control group will receive sham taping. The application will begin at postoperative week 6 after complete discontinuation of splint immobilization. In the sham application, all steps of the KT procedure (cutting, placement, and application process) will be mimicked; however, no therapeutic tension will be applied to the tapes. Sham taping will be applied twice weekly between postoperative weeks 6 and 12, using three tapes per session. New tapes will be applied in each session and replaced no later than 3 days after the previous application. Before each application, the taping area will be properly cleaned. Patients and their caregivers will also be thoroughly informed about hygiene and proper tape removal.

Button-Hole Technique (Affected finger(s)) I-Strip Technique (Support for all metacarpal bones) Supportive Tape Application

With the wrist in a neutral position, active flexion and extension movements of the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints will be measured using a metal finger goniometer.

Gross grip strength will be measured using a hand dynamometer, and pinch strength will be measured in four different positions (tip, pulp, lateral, and three-point pinch) using a pinch meter (Jamar® Hydraulic Dynamometer-Pinchmeter, Serial No: 1420513), according to the standard measurement protocol of the American Society of Hand Therapists.

The MHQ was developed to measure health status in patients with hand deformities and assesses how well patients perform their usual activities. Each question is scored on a 5-point Likert scale. The total score is calculated by summing all domain scores and dividing by six. Higher scores indicate better outcomes. The questionnaire will be administered by the researchers through face-to-face interviews using a question-and-answer format
