<![CDATA[Background: Proximal one-third left radius and ulna fractures treated with Open Reduction Internal Fixation (ORIF) may be accompanied by pain, limited joint range of motion, decreased muscle strength, and impaired functional activity. In this case, the patient presented with movement pain, tenderness, limited joint range of motion, and reduced functional ability of the left upper extremity. Infrared was applied as a thermotherapy modality to provide heat to superficial tissues, while therapeutic exercises included stretching, active exercise, and hold relax to support joint mobility. Objective: This study aimed to describe changes in pain, joint range of motion, muscle strength, and functional activity following physiotherapy intervention in a patient with post-ORIF proximal one-third left radius and ulna fractures. Methods: A case study design was conducted involving one patient who received four physiotherapy sessions. Pain was assessed using the Visual Analogue Scale, joint range of motion was measured using a goniometer, muscle strength was assessed using Manual Muscle Testing, and functional activity was evaluated using the Wrist and Hand Disability Index. Results: After four therapy sessions, movement pain decreased from 5 to 2, resting pain from 1 to 0, and tenderness from 3 to 2. Joint range of motion at the elbow and wrist improved compared with the initial assessment, accompanied by improved functional activity. Conclusion: The combination of infrared and therapeutic exercise was accompanied by improvements in pain, joint range of motion, and functional activity during four physiotherapy sessions in a patient with post-ORIF proximal one-third left radius and ulna fractures.]]>
