Most physiotherapists would want to see you on average two times a week in the beginning for moderate to severe conditions. Eventually the frequency would be reduced when clients are ready to manage their condition more on their own. Orthopedic conditions require more stimulation in the beginning and also frequent visits in the beginning would ensure that clients are monitored more closely. Also, your therapist would progress the force used during the treatment session to match your current condition and try to bring you past your barriers every time.
