The number of sessions you will need depends on your particular condition and your willingness to do a short series of gentle exercises between sessions. Most people experience notable improvement after 3-5 sessions. The more regular you are about doing the exercises at home, the faster you will improve.
After their pain is gone and efficient movement patterns are re-established, some clients may want to have periodic individual sessions to deepen their Hanna Somatics exercise practice and their sensory-motor awareness. How you use individual sessions, how many sessions you need or want, and how often you come for sessions all depend upon your goals and interests.
