Return to HUMAC NORM Overview

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.

Patterns

To jump to a specific set of patterns, choose from the list below: Knee Ankle Elbow PNF D1 Forearm / Wrist PNF D2 Hip Trunk (Optional) Shoulder

Knee: Extension / Flexion Seated

Axis of Rotation: The most accurate fixed axis for rehab or testing of the knee is a line passing transversely through the femoral condyles. Parts Needed: Contralateral Limb Stabilizer Knee/Hip Adapter Knee/Hip Pad Lumbar Cushion

Knee: Extension / Flexion Prone

Axis of Rotation: The most accurate fixed axis for rehab or testing of the knee is a line passing transversely through the femoral condyles. Parts Needed: Knee/Hip Adapter Knee/Hip Pad

Knee: Tibial Internal / External Rotation

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 Footrest

Ankle: Plantar / Dorsiflexion Prone

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

Ankle: Plantar / Dorsiflexion Supine

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

Ankle: Inversion / Eversion

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. Parts Needed: Ankle Adapter Footplate Thigh Stabilizer Pad Thigh/Forearm Stabilizer Tube Footrest

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

Back to Top Shoulder: Extension / Flexion 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 Back to Top Shoulder: Horizontal 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 90° horizontal abduction. Parts Needed: Elbow/Shoulder Adapter Footrest Torso Belt

Shoulder: Internal / External Rotation in 90º Abduction

Axis of Rotation: The axis of rotation is the longitudinal axis of the humerus. Parts Needed: Wrist/Shoulder Adapter Elbow Stabilizer Pad Torso Belt Footrest

Shoulder: Internal / External Rotation, Mod Standing

Axis of Rotation: The axis of rotation is the longitudinal axis of the humerus. Parts Needed: Wrist/Shoulder Adapter Elbow Stabilizer Pad

Shoulder: Internal / External Rotation, Mod Seated

Axis of Rotation: The axis of rotation is the longitudinal axis of the humerus. Parts Needed: Wrist/Shoulder Adapter Elbow Stabilizer Pad Lumbar Cushion

Shoulder: Internal / External Rotation in 90º 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

PNF D1: Flexion - Adduction / Extension - Abduction

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. Parts Needed: Elbow/Shoulder Adapter Footrest

PNF D2: Flexion - Abduction / Extension - 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. The motion for the pattern begins in full Extension-Adduction and moves to full Flexion-Abduction. In order to attain full Extension-Adduction, the limb should be pronated and internally rotated. Parts Needed: Elbow/Shoulder Adapter Footrest Torso Belt

Forearm: Pronation / Supination

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. Parts Needed: Thigh/Forearm Stabilizer Tube Forearm Stabilizer V-Pad Wrist/Shoulder Adapter Lumbar Cushion Counterbalance Weight

Wrist: Extension / Flexion

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). Parts Needed: Thigh/Forearm Stabilizer Tube Forearm Stabilizer V-pad Wrist/Shoulder Adapter Lumbar Cushion

Wrist: Radial / Ulnar Deviation

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. Parts Needed: Thigh/Forearm Stabilizer Tube Forearm Stabilizer V-pad Wrist/Shoulder Adapter Lumbar Cushion

Elbow: Extension / Flexion

Axis of Rotation: The axis of rotation is immediately distal to the lateral epicondyle and moves only slightly anteriorly as flexion increases. Parts Needed: Elbow/Shoulder Adapter Footrest Lumbar Cushion

Hip: Abduction / Adduction

Axis of Rotation: The axis of rotation is superior and medial to the greater trochanter. Parts Needed: Knee/Hip Adapter Knee/Hip Pad

Hip: Flexion / Extension

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

Hip: Internal / External Rotation

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. Parts Needed: Ankle Adapter Footplate Footrest

Trunk: Flexion / Extension

Axis of Rotation: The axis of rotation is located at the L5-S1 level. To align the axis: Vertically - adjust the footplates until the axis alignment pointer on the unit is approximately 1” distal to the iliac crest. Horizontally - have the patient lean against the rear pad. Adjust fore/aft position until the axis alignment pointer intersects the mid-axillary line and L5-S1. Parts Needed: TEF Modular Component
