SBC Client Assessment and Screening 2

Question 1

What does the term 'kinetic chain' mean in the context of a stability ball assessment?

Accepted Answer

The interdependence of all joints and muscles from feet to head affecting movement quality

Answer

The kinetic chain describes the interconnected system of joints, muscles, and connective tissue from the foot to the head, where dysfunction at one segment affects others during stability ball movement.

Question 2

Which muscle is commonly identified as 'overactive' in clients with lower crossed syndrome affecting stability ball posture?

Accepted Answer

Hip flexors (iliopsoas)

Answer

In lower crossed syndrome, the hip flexors (iliopsoas and rectus femoris) are typically overactive and shortened, contributing to anterior pelvic tilt and poor stability ball posture.

Question 3

A client demonstrates 'knee valgus' during stability ball wall squats. This compensation most likely indicates weakness in which muscle?

Accepted Answer

Gluteus medius

Answer

Knee valgus (knees caving inward) during squat movements typically reflects weakness in the gluteus medius, which normally prevents inward collapse of the femur.

Question 4

Before using the stability ball with a client who has osteoporosis, the trainer must be most cautious about:

Accepted Answer

Exercises involving spinal flexion under load and fall risk

Answer

Clients with osteoporosis are at elevated fracture risk; spinal flexion under load stresses vertebral bodies and fall risk from an unstable ball can lead to serious injury.

Question 5

Which movement screen finding suggests the client needs hip mobility work before stability ball glute bridges?

Accepted Answer

Inability to achieve full hip extension lying flat

Answer

Inability to achieve full hip extension indicates hip flexor tightness that will limit the range and effectiveness of stability ball glute bridges and cause lumbar compensation.
