Positioned on a table: This aid is used to invite and guide the patient through prone supination tasks with their forearm. Two knobs below the equipment are used to position it correctly for the patient.
The proximal support on which the forearm is placed must be adjusted to a height that keeps the shoulder in a comfortable, neutral position.
By raising and lowering the adjustment element with the elbow flexed, the position is changed to extra/intra rotation of the upper limb respectively.
The knob nearest to the handle is used to adjust it to the correct tilt on the prone supination plane, while the upper knob is used to adjust a system that is able to provide resistance to the movement by the patient, which can be varied in intensity.
The patient is therefore asked to overcome the resistance offered by the aid, and the extent of that resistance is determined by the therapist in relation to the therapeutic goal.
