This group of participants will receive only standard care, defined as conventional physiotherapy, during their rehabilitation process following distal radius fracture surgery. The treatment program will commence at the 6th week post-surgery and will be applied twice a week for 6 weeks (totaling 12 sessions), with each session lasting an average of 30-35 minutes. Conventional physiotherapy includes joint range of motion exercises (flexion, extension, ulnar/radial deviation for the wrist; supination/pronation for the elbow) for 10 repetitions. Strengthening exercises, utilizing Theraband for wrist movements (10 repetitions) and Powerweb/Theraputty for grip strength (10 repetitions), will be applied, with resistance levels set at approximately 60-70% of the 1 Repetition Maximum method. Additionally, Closed Kinetic Chain exercises (wall press, plyometric wall push-ups, crawling, and push-ups after week 5) will be incorporated starting from the 3rd week of conventional treatment.

The Mulligan Group will receive Mobilization With Movement (Mulligan MWM) techniques in addition to conventional physiotherapy, aiming to achieve pain-free movement by correcting the "positional fault" in the joint. The treatment will be administered for 6 weeks starting from the 6th week post-surgery, with 2 sessions per week (totaling 12 sessions) , and the MWM component will last approximately 15-20 minutes. MWM techniques, which must be performed pain-free, are initiated with the lateral glide of the carpal row and include continuous lateral glide to improve wrist flexion and extension. Furthermore, MWM of the distal and proximal radioulnar joint to improve supination will be added to the program starting from the 3rd week. Each mobilization is applied as 3 sets of 10 repetitions , with a rest period of 15-20 seconds between sets. To ensure continuous pain-free movement, patients will also be taught self-mobilization (10 repetitions) to be performed at home.

Patients receive the standard physical therapy program only.

The Tampa Scale of Kinesiophobia (TSK) is a self-report measure developed to assess the fear of pain related to movement in patients with musculoskeletal pain. It consists of 17 questions designed to measure the fear of movement and re-injury. The scale utilizes a 4-point Likert scoring system (1 = strongly disagree, 4 = strongly agree). The items are grouped into two distinct factors: activity avoidance and somatic focus. The TSK is commonly used in distal radius fracture cases to assess general fear of movement.

Application in Your Study: In your project, this assessment will be performed using both a universal goniometer and an electrogoniometer (K Force Sens).The patient is asked to memorize a target angle (20 extension) and then actively reproduce it, with the difference between the target angle and the measured angle recorded as the degree of error.

Visual Analog Scale (VAS) Used to rate the severity of the patient's pain. It typically consists of a 100 mm line with two descriptors representing extreme pain intensity (e.g., no pain and worst possible pain) at either end. Patients mark their intensity on the line, and the score is measured as the distance from the "no pain" end.
