MPT Rehabilitation and Therapeutic Exercise 2

Question 1

Aquatic therapy is advantageous for rehabilitation primarily because water provides:

Accepted Answer

Buoyancy to reduce weight-bearing and resistance for movement

Answer

Water buoyancy reduces effective body weight (up to 90% at neck depth), allowing earlier exercise with reduced joint loading while providing resistance in all directions.

Question 2

Which physiological adaptation primarily explains strength gains in the first 4–6 weeks of resistance training in a deconditioned patient?

Accepted Answer

Neural adaptations (motor unit recruitment and synchronization)

Answer

Early strength gains are predominantly neural: improved motor unit recruitment, rate coding, and synchronization before significant muscle hypertrophy occurs.

Question 3

Open kinetic chain (OKC) exercises differ from closed kinetic chain (CKC) exercises in that OKC exercises:

Accepted Answer

Allow the distal segment to move freely in space

Answer

In OKC exercises the distal segment (hand or foot) moves freely, allowing isolated muscle activation; in CKC the distal segment is fixed, promoting co-contraction.

Question 4

Deload weeks are programmed into therapeutic exercise plans to:

Accepted Answer

Allow tissue recovery and prevent overtraining and overuse injury

Answer

Planned deload periods reduce volume or intensity to allow accumulated fatigue to dissipate, enabling tissue repair and supercompensation.

Question 5

Which muscle action is involved when a patient slowly lowers a heavy object from a shelf?

Accepted Answer

Eccentric elbow flexion (biceps lengthening under load)

Answer

Lowering a heavy object slowly requires the biceps to control the descent eccentrically — generating force while lengthening to brake against gravity.
