Mirror therapy is the intervention aimed to improve functional aspects by creating a reflective illusion and mirror neuron system. Although there are many researches stating its effectiveness in neurological and orthopedic injuries, it has not been used widely in clinical settings for upper-limb fracture cases. A 69-year-old female sustained a right humeral shaft fracture and underwent open reduction internal fixation. Following the surgery, the patient was referred to the physiotherapy (PT) department for wrist drops, pain, and stiffness in the shoulder joint. The patient received conventional PT (electrical stimulation and exercises) for the first 3 weeks. Later, mirror therapy was introduced for wrist and shoulder movements. She was evaluated for pain, range of motion of shoulder and wrist joints, and functional ability at baseline, at 3 weeks, and at 6 weeks. There was an improvement in all outcome measures predominantly within 3rd week–6th week. Mirror therapy showed positive effects on upper-limb functions when combined with conventional therapy.
