Abstract

The invention provides a cordless chiropractic adjustment device including a thrust element (80) capable of impacting a body contact member (10), a resilient spring (314) arranged to bias the thrust element towards the body contact member, and a motor (120). The motor is arranged to move the thrust element between a variable primed configuration in which the thrust element is held out of contact with the body contact member, and a fired configuration in which the thrust element is propelled by the resilient spring into contact with the body contact member through a range of different impact forces. The motor is provided with direct current by one or more batteries (150), which may be rechargeable.
