Each of the Following Principles Is Important When Designing a Therapeutic

Each of the following principles is important when designing a therapeutic exercise program to correct hip muscle length/strength imbalances except:

A) When stretching the hip musculature,the spine and pelvis must be stabilized against the force.
B) Contraction of the muscle opposite the range-limiting muscle (i.e. ,contracting the antagonist of the tight muscle) to assist with the stretching maneuver has the benefit of training the antagonist muscle to function in any newly gained range.
C) Because of the functional demands placed on the lower extremities,it is more important to have full hip range of motion than to have "normal" strength of hip musculature.
D) Strengthening exercises should include closed-chain exercises to prepare for functional activities in weight-bearing postures.
