FRC Assessment & Mobility Training Techniques

Question 1

In FRC terminology, how is 'mobility' best distinguished from 'flexibility'?

Accepted Answer

Mobility is the range a joint can actively control; flexibility is the range it can reach passively

Answer

FRC defines mobility as actively controllable range, whereas flexibility is the passive range available.

Question 2

A client shows 45 degrees of passive hip internal rotation but only 20 degrees actively. What does FRC call this difference?

Accepted Answer

The passive-active gap

Answer

The difference between passive and active range is the gap FRC training aims to close.

Question 3

What is the primary purpose of performing CARs at the start of a training session?

Accepted Answer

To assess and maintain joint health by moving through the largest controllable rotational range

Answer

CARs serve as both a daily joint-health practice and an ongoing self-assessment of usable range.

Question 4

During a hip CAR, the client's pelvis tilts and the lumbar spine flexes as the knee circles. What should the coach cue?

Accepted Answer

Increase full-body tension (irradiation) and reduce range to keep motion isolated at the hip

Answer

CARs require isolation, so compensation is controlled with irradiation and a smaller, owned range.

Question 5

In the Functional Range Assessment (FRA), why are passive and active ranges both measured?

Accepted Answer

To determine whether a limitation is a tissue/joint restriction or a lack of active control

Answer

Comparing passive and active ranges helps separate structural limits from control deficits.
