COT Visual Assessment 3

Question 1

During a visual assessment of a patient's gait, you notice the patient leans their trunk laterally toward the stance limb during the loading response phase. This compensatory pattern most likely indicates weakness in which muscle group?

Accepted Answer

Hip abductors on the stance side

Answer

Lateral trunk lean toward the stance limb (Trendelenburg gait) is a compensatory strategy used when the hip abductors (primarily gluteus medius) are weak. By shifting the center of mass over the stance limb, the patient reduces the demand on the abductors to keep the pelvis level during single-limb support.

Question 2

When performing a visual postural assessment in the sagittal plane, a therapist observes increased thoracic kyphosis combined with forward head posture. Which of the following cervical spine adaptations is MOST commonly associated with this finding?

Accepted Answer

Upper cervical extension with lower cervical flexion

Answer

With forward head posture arising from thoracic kyphosis, the lower cervical spine tends to flex (following the thoracic curve), while the upper cervical spine extends to maintain a horizontal gaze. This 'craniovertebral extension' pattern is the classic adaptation seen with this postural deviation.

Question 3

A COT candidate is observing a patient performing a unilateral overhead reach task. They note the patient demonstrates early scapular elevation and reduced posterior tilting on the reaching side. This scapular movement pattern most directly suggests dysfunction in which muscle?

Accepted Answer

Lower trapezius

Answer

The lower trapezius is primarily responsible for scapular depression and posterior tilting during overhead elevation. Deficiency in this muscle leads to compensatory early and excessive scapular elevation and insufficient posterior tilt, reducing subacromial space and compromising optimal glenohumeral mechanics.

Question 4

During visual assessment of a patient's standing posture, the therapist notes that the patient's right iliac crest is higher than the left. In the frontal plane, which of the following lateral deviations of the lumbar spine would MOST likely accompany this finding?

Accepted Answer

Lumbar lateral flexion concave toward the right

Answer

When the right iliac crest is elevated (right pelvic hike or left pelvic drop), the lumbar spine typically develops a lateral curve that is concave toward the right (a right lateral convexity) to keep the trunk centered over the base of support. The concavity faces the elevated side.

Question 5

A therapist performing a visual assessment of stair descent observes a patient who demonstrates excessive knee valgus on the right during the loading phase on each step. Which combination of findings would BEST support a proximal cause for this movement fault?

Accepted Answer

Hip internal rotation with ipsilateral pelvic drop and weak hip abductors

Answer

Proximal contributors to knee valgus during weight-bearing tasks include hip internal rotation and contralateral (or ipsilateral) pelvic drop, both of which indicate hip abductor and external rotator weakness. These proximal deficits cause the femur to adduct and internally rotate, collapsing the knee medially regardless of foot position.
