Flexible members for anchoring to the body

A flexible anchor member comprising:

• an outer member for placement about a body part, the outer member including a substantially inextensible textile material configured for directing a force applied by an actuator to act upon all or a portion of the body part;
• an inner member for positioning between the body part and the outer member, a first surface of the inner member being configured for frictionally engaging the body part or any intervening clothing;
• at least one coupler for coupling the outer member and the inner member;
• at least one substantially inextensible textile element partially or fully circumscribing a portion or all of the outer member and configured in one or more locations to be secured to itself or to the outer member;
• and
• a force transfer coupler including two arms fixedly coupled to the member and a stem fixedly coupled to the at least one substantially inextensible textile element,
• wherein the force transfer coupler is configured to couple a portion of the at least one substantially inextensible textile element to an actuator such that a force applied by the actuator causes the at least one substantially inextensible textile element to constrict about the outer member for a duration of the applied force.
