Protocol for Positioning and Helmet Removal-The Prone Athlete

If an athlete is found in the prone position after an injury, cervical spine injury should be assumed. The team physician and the training staff should complete their initial evaluation (i.e., primary survey) without moving the athlete. The team physician and athletic trainer position themselves by the patient. The trainer stabilizes the cervical spine […]

Ankle and foot-POSTERIOR

Calcaneus, medial and lateral malleolus are visible landmarks. The upper surface of the tuber calcanei can easily be palpated and forms the basis of the triangle whose legs are formed by the anterior border of the Achilles tendon and the posterior aspect of the tibia.The posterior border of the talus, nipped between tibia and caleaneu, […]

External recurvatum test

Positioning.

The subject lies supine with both legs relaxed and extended. The examiner grasps the big toes.

Procedure.

Both legs are lifted simultaneously. The amount of external rotation of the tibial plateau and the degree of recurvatum are observed. In a positive test, unilateral excess of external rotation and recurvatum is seen.

Resisted lateral rotation

Positioning.

The subject sits with the lower legs pendent. The examiner squats in front of the knee. The ipsilateral hand is placed against the lateral aspect of the forefoot and maintains dorsiflexion. The contralateral hand encircles the heel from the medial side.

Procedure.

The patient is asked to turn the foot outwards while the examiner […]

Resisted medial rotation

Positioning.

The subject sits with the lower legs pendent. The examiner squats in front of the knee. The ipsilateral hand encircles the heel from the lateral side. The contralateral hand is placed against the medial aspect of the forefoot and holds the foot in dorsiflexion .

Procedure.

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 […]

Passive extension

Positioning..

The subject lies in the supine position with the legs extended. The examiner stands level with the subject’s knee. One hand grasps the lower leg at the heel, while the other carries the knee from the lateral side with the thumb on the tibial tuberosity.

Procedure. Move the leg upwards. Perform a quick and […]

PASSIVE TESTS-Passive flexion

Positioning.

The subject lies in the supine position with extended legs. The examiner stands level with the subject’s knee. One hand grasps the distal part of the leg, just proximal to the malleoli; the other hand grasps the knee at the medial femoral condyle.

Procedure.

Move the extended leg upwards until the knee can […]

Resisted medial rotation

POSitioning.

The subject lies in the prone position with the hips slightly abducted and the knees flexed to 90°. The examiner sits at the foot·end of the couch, just distal to the knees, and places both hands against the outer malleoli.

Procedure.

Ask the subject to push the legs in an outward direction, and […]
