Study Notes

Rotational Range of Motion

Primary range of motion that allows the hand to rotate from palm facing up to palm facing down is forearm rotation.

Shoulder Examination

Not one of the key points of interest when examining the shoulder is the wrist joint.
Normal range of motion for shoulder abduction is 0-180 degrees.
Not a recommended technique for examining the major joints is bouncing the joint.

Shoulder Range of Motion

Normal range of motion for shoulder internal rotation is 0-70 degrees.

Shoulder Bones

Not considered an important bone of the shoulder is the fibula.

Thumb Abduction

Most sensitive test for assessing weak abduction of the thumb is the Froment's sign test.

Phalen's Sign Test

Recommended duration for the Phalen's sign test is 1 minute.

Spine

There are 5 types of vertebrae found in the spine: cervical, thoracic, lumbar, sacrum, and coccyx.
Recommended range of motion for spinal flexion is 40-60 degrees.
Recommended range of motion for spinal lateral bending is 20-40 degrees.

Musculoskeletal Complaint

Most important characteristic to identify when evaluating a musculoskeletal complaint is pain.
In a patient under 60 years old with a musculoskeletal complaint, trauma should be considered first.
If a patient presents with an acute musculoskeletal complaint with inflammation, trauma should be considered.
In a patient over 60 years old with a musculoskeletal complaint, degenerative changes should be prioritized in the differential diagnosis.
Term 'varus' in the context of musculoskeletal disorders refers to inward angulation of a bone.
If a patient presents with a chronic musculoskeletal complaint without inflammation, degenerative changes should be considered.

Ankle and Foot Examination

Not part of the inspection and palpation examination for the ankle and foot is testing the strength of the muscles.
Tibiotalar joint is not assessed during the range of motion examination for the ankle and foot.
Tibialis anterior muscle is primarily responsible for ankle dorsiflexion (pointing the foot toward the ceiling).
Inversion and eversion motions are not specific to the ankle joint, but rather occur at the subtalar joint.
Flexor digitorum longus muscle group is primarily responsible for toe flexion (curling the toes).
Inversion and eversion motions are assessed by stabilizing the ankle, grasping the heel, and inverting/everting the foot.

Knee

Quadriceps muscle group is primarily responsible for knee extension.
McMurray's maneuver is used to test the integrity of the medial meniscus.
Pivot shift test is used to assess the integrity of the anterior cruciate ligament (ACL).
Deltoid ligament is considered the most stable in the ankle and foot region.
Popliteus muscle group is primarily responsible for internal rotation of the knee.
Posterior drawer test is used to assess the integrity of the posterior cruciate ligament (PCL).
