Physical therapy machines are specialized devices used to aid in the rehabilitation of patients recovering from injuries or surgeries. These machines can help improve strength, flexibility, and mobility through guided exercises. Common types include ultrasound machines, which use sound waves to promote healing, and electrical stimulation units, which help reduce pain and improve muscle function. In addition to these, therapeutic exercise equipment like treadmills and stationary bikes are often used to enhance cardiovascular fitness. Hydrotherapy pools provide a low-impact environment for exercises, making it easier for patients to move and recover. Overall, these machines play a crucial role in the recovery process.
