Clinical Question – Length of Treatment
How often and how long do I need physical therapy?
Depending on your condition, the therapist will give you an approximate timeline. On average, physical therapy is usually 2 days a week for approximately 4-6 weeks. Patients that have an extensive past medical history might take longer to heal; therefore, requiring a longer duration of physical therapy. Examples that affect the duration include: diabetes, age, smoking, history of slow healing wounds, malnutrition, previous injury to the area being treated, and previous surgery to the area or limb being treated.
