A treatment force application device includes a proximal end having a weight and having a support for a practitioner; a distal end having a treatment interface configured for applying a therapeutic treatment including at least a treatment force; and a connection between the support and the treatment interface. The connection is lockably adjustable by the practitioner to establish a placement of the treatment interface relative to the support. The weight is sufficient to substantially prevent movement of the treatment interface relative to the support when the connection is locked. The support enables movement of the practitioner to provide a practitioner force, and the practitioner force is transferred from the support to the treatment interface through the connection.
