A client was referred to occupational therapy after a left distal radius fracture. The cast was removed yesterday, AROM was measured at wrist flexion: 25 degrees, wrist extension: 30 degrees. The patient presents with mild edema throughout left wrist and digits, and stiffness throughout left hand and wrist. You are beginning the first intervention session, which physical agent modality is the most appropriate to apply to address the stiffness in the wrist and hand?
