The objective will be to determine the effectiveness of adding unilateral upper limb postoperative training to standard rehabilitation compared to standard rehabilitation on maximum grip strength and manual dexterity in patients aged 30-50 years with surgically treated distal radius fracture. It is presumed that the addition of unilateral upper limb training will significantly improve maximum grip strength and manual dexterity at the end of the intervention period compared to the group receiving only standard rehabilitation.
Patients who agree to participate in this research will be randomly assigned to a control group (standard rehabilitation with unilateral training with mobility exercises) or an experimental group (standard rehabilitation with unilateral high-intensity strength training). The duration of the postoperative intervention will be 12 weeks. The primary variables are maximum grip strength and manual dexterity. Secondary variables are wrist mobility, forearm circumference, maximum voluntary isometric strength, functionality and health-related quality of life. Results will be measured at 0, 6 and 12 weeks postoperative.

| Standard rehabilitation | Other | Protocol based on the best available evidence and to be used in all participants in both groups. The standard rehabilitation protocol will consist of three postoperative phases: Mobilization (0 to 4 weeks), Strengthening (4 to 8 weeks) and Functional phase (8 to 12 weeks). Sessions will be held 3 times a week for 12 weeks. Each session will last 1 hour and will consist of different modalities of therapeutic exercise and cryotherapy. |

| Unilateral high-intensity strength exercise | Other | Participants will be seated in an armchair with armrests and will perform 4 sets of 8 repetitions of an eccentric exercise for the pronosupinator muscles with a dumbbell with adjustable weights. The training will start with an intensity of 60% of 1RM, until reaching 80% 1RM. |
