Limited Range of Motion (ROM) can be caused by a variety of factors, such as injury, surgery, or medical conditions like arthritis. The most common therapy used to improve ROM is physical therapy.

Physical therapy involves exercises and stretches designed to improve flexibility and mobility in the affected area. A physical therapist will work with the patient to create a customized treatment plan based on their specific needs and goals.

The therapy may include different techniques, such as range-of-motion exercises, resistance training, and manual therapy techniques like massage and joint mobilization. Additionally, the therapist may incorporate modalities such as heat or ice therapy, ultrasound, or electrical stimulation to help improve the patient's ROM.

It is important to note that the specific therapy used will depend on the underlying cause of the limited ROM and the patient's individual needs. Therefore, it's essential to consult with a qualified healthcare professional to determine the best course of treatment.
