Dermatomes
This dermatome is associated with sensation over the thumb.
What is C6
This test is commonly used to assess the ACL and is performed with the knee flexed approximately 20–30° while applying anterior translation to the tibia.
What is Lachman's
This muscle and nerve root is the primary muscle responsible for shoulder abduction
What is the middle Deltoid and Axillary nerve (C5-6)
This nerve innervates the quadriceps femoris, making it the primary nerve responsible for knee extension.
What is the Femoral Nerve
According to commonly used AAOS reference values, Fulcrum placement at ASIS is for what measurement:
What is hip abduction
A patient reports numbness over the middle finger. Which cervical dermatome should the PTA suspect?
What is C7
A patient has knee pain after a twisting injury. This test reproduces symptoms by combining knee flexion, tibial rotation, and valgus/varus stress.
What is McMurray=Meniscus
This rotator cuff muscle and nerve root is primarily responsible for external rotation of the shoulder
What is infraspinatus; suprascapular nerve with Teres minror; axillary nerve
This nerve innervates the gluteus medius and gluteus minimus, which are important for hip abduction and pelvic stability during single-leg stance.
What is the Superior Gluteal Nerve
According to commonly used AAOS reference values, normal knee flexion is approximately:
What is 1325 Degrees
Sensation over the medial forearm and little finger is primarily associated with which nerve root?
What is C8
This test is performed by placing the patient in supine with the hip and knee flexed, then moving the hip through abduction and external rotation. Pain or inability to lower the leg may indicate a hip flexor or hip joint problem.
What is the Thomas Test
Which rotator cuff muscle and nerve root is primarily responsible for internal rotation of the shoulder?
What is the subscapular muscle and subscapular nerve
This nerve innervates the tibialis anterior, which is responsible for ankle dorsiflexion and inversion.
What is the Deep Peroneal(Fibular) nerve
A patient demonstrates 10° of knee extension when measured from the neutral position. How would this ROM limitation typically be documented?
10 Degress flexion contracture
A patient reports decreased sensation around the umbilicus. Which dermatome is most likely involved?
What is T10
A soccer player sustains a valgus force to the knee. To assess the integrity of the medial collateral ligament, the therapist applies a valgus force at approximately 30° of knee flexion.
What is Valgus Stress Test(MCL)
A patient has difficulty performing scapular elevation and upward rotation. Which muscle and nerve are compromised?
What is the Upper trapezius and accessory nerve (CNXI)
This nerve innervates the hamstrings and is the major nerve associated with hip extension and knee flexion.
According to commonly used AAOS reference values, normal Dorsiflexion is approximately:
What is 20 degrees
A patient has decreased sensation over the medial aspect of the lower leg and medial malleolus. Which dermatome is MOST likely affected?
What is L4
During Ober's Test, the therapist extends and abducts the hip, flexes the knee, and then allows the hip to move into adduction. The test is considered positive when the thigh fails to drop toward the table.
What is the TFL tightness
This muscle and nerve is responsible for scapular retraction
Rhomboids and dorsal scapular nerve
A patient has difficulty performing ankle eversion after an injury. Which nerve and muscles are MOST likely affected?
What is the Common Peroneal (Fibular ) Nerve; AKA superficial fibular nerve
According to commonly used AAOS reference values, Fulcrum placement at the lateral epicondyle of the femur is for what measurement:
What is knee flexion
