Body work encompasses many different forms of therapeutic touch, including systems that retrain the body for optimal functioning. Examples include the Alexander technique, Trager, and Rolfing, which are require a high level of training. However, body work is different from a classic massage, and sometimes people without a massage license call themselves bodyworkers.
Reflexology is a spa treatment where the therapist works on "reflex points" on your feet, hands, and head (especially ears). The theory behind reflexology is that these reflex points relate to specific organs and glands in the body, and stimulating those points with finger pressure promotes health in those organs and glands via the body's energetic pathways.
