Protocol for Positioning and Helmet Removal-Removal of Helmet and Shoulder Pads

Manual stabilization of the cervical spine is maintained by placing one hand on each side of the athlete’s helmet. The chin strap is cut, and all accessible internal padding is removed.

Why rubbing it better makes pain go away

Rubbing a sore knee or arm after a bump really does help make the pain go away, say scientists.

Researchers have discovered that gentle stroking activates “pleasure” nerves beneath the skin, which then reduce the sensation of pain from other nerves.

They found that people who were exposed to painful temperatures on the surface of […]

Passive supination

Procedure.

Perform an abduction movement in the shoulder: the thumb pulls the inner side of the foot upwards while the fingers push the outer side downwards.

Common mistakes.

The ankle and subtalar joints are not stabilized.

Normal functional anatomy:

• Rallge: 45-90° • End-feel: soft ligamentous • Limiting structures: medial and lateral midtarsal ligaments.

Passive plantar flexion

Procedure:

Press the fingers downwards by a pronation of the wrist.

Common mistakes.

The ankle and subtalar joints are not stabilized.

Normal functional anatomy:

• Rallge: 10-150 • Elld-feel: hard ligamentous • Lilllilillg sln/etL/res: dorsal midtarsal ligaments.

Lateral shearing

Significance

This test is used to detect internal derangement at the outer side of the knee.

Positioning.

The subject lies in the supine position,with the knee flexed to a right angle and the heel resting on the couch. The examiner sits opposite the subject at the foot-end of the couch. The heel of the […]

SPECIFIC TESTS-Medial shearing

Significance

This test is used to detect internal derangement at the inner side of the knee. Pain on jerk is suggestive for a minor lesion at the tibial insertion of the anterior cruciate ligament.

Positioning.

The subject lies in the supine position with the knee flexed to a right angle, and the heel resting […]

Variation: anterior drawer in 20· of flexion (Lachman test)

Positioning.

The subject lies in the supine position with the legs extended. The examiner stands level with the knee. One hand grasps the proximal tibia from the medial side, the fingers in the popliteal fossa and the thumb at the tibial tuberosity. The other hand holds the distal femur from the lateral side, the thumb […]
