The HUMAC NORM includes attachments to perform 22 isolated patterns covering the shoulder, elbow, wrist, hip, knee, and ankle. Isolated patterns are used to accurately and carefully measure and build the foundation for safe functional testing and exercise.
Optional attachments add Work Simulation and Trunk extension / flexion patterns.
Testing
Patterns
Shoulder:
Shoulder: Abduction / Adduction
Axis of Rotation: The instantaneous axis of rotation changes throughout the movement. The compromise axis is medial to the acromion process when the limb is in the neutral position.
Parts Needed: Elbow/Shoulder Adapter Footrest Lumbar Cushion
Axis of Rotation: The instantaneous axis of rotation changes throughout the movement. The compromise axis is medial to the acromion process when the limb is in the neutral position.
Axis of Rotation: The instantaneous axis of rotation changes throughout the movement. The compromise axis is medial to the acromion process when the limb is in 90° horizontal abduction.
Parts Needed: Elbow/Shoulder Adapter Footrest Torso Belt
Shoulder: Internal / External Rotation in 90° Flexion
Axis of Rotation: The axis of rotation is the longitudinal axis of the humerus. If length adjustment of wrist / shoulder adapter is correct, and elbow flexed at 90° with forearm parallel to input arm, the axis alignment will be established and maintained by the Elbow Stabilization Pad.
Parts Needed: Wrist/Shoulder Adapter Elbow Stabilizer Pad
Axis of Rotation: The instantaneous axis of rotation changes throughout the movement. The compromise axis is medial to the acromion process when the limb is in the neutral position. The motion for this pattern begins in full Extension-Abduction and moves to full Flexion-Adduction, the limb should be supinated and externally rotated.
Axis of Rotation: The axis of rotation bisects the head of the ulna distally and the head of the radius proximally. It is established by placing the forearm directly in line with the dot on the dynamometer input tube at approximately the level of the ring finger.
Axis of Rotation: This axis alignment is critical and somewhat difficult in the pattern. The axis of rotation is slightly oblique passing through the wrist just distal to the tubercle of the radius and the head of the ulna (approximately where the hand meets the wrist).
Axis of Rotation: The axis of rotation is located approximately at the center of the capitate bone. This is found at the middle of the wrist just distal to the axis for extension/flexion.
Axis of Rotation: The axis of rotation is slightly anterior in extreme flexion as the pelvis tilts to increase range of motion. The normal movement synergy does not affect testing accuracy.
Parts Needed: Knee/Hip Adapter Knee/Hip Pad Footrest
Axis of Rotation: The axis of rotation is a mechanical axis of the femur (line through centers of hip and knee joints). This can be visualized, approximated and then fine adjusted during warm up/familiarization repetitions.
Axis of Rotation: The axis of rotation is slightly medial to the longitudinal axis of the tibia. This can be visualized, approximated and then fine adjusted during warm up/familiarization repetitions.
Parts Needed: Ankle Adapter Footplate Thigh Stabilizer Pad Thigh/Forearm Stabilizer Tube Footres
Axis of Rotation: The axis of rotation passes obliquely (approximately 16° anteromedially) through the tip of the fibula (lateral malleous) and the trochlea of the talus, exiting just distal to the tip of the tibia (medial malleous).
Axis of Rotation: The axis of rotation passes obliquely (approximately 16° anteromedially) through the tip of the fibula (lateral malleous) and the trochlea of the talus, exiting just distal to the tip of the tibia (medial malleous).
Parts Needed: Ankle Adapter Footplate Footrest Thigh Stabilizer Pad Thigh/Forearm Stabilizer Counterbalance Weight
Axis of Rotation: The axis is compound and changes throughout range of motion of the talo-crural joint, talocalcaneal joint and talonavicular/ calcanecuboid or transverse tarsal joint.
