Question

An OTR included exercises as an adjunctive modality in the treatment plan after the client expressed that he wanted to include exercises to improve his endurance and strength. The client has no limits to range of motion and has a muscle strength of at least fair plus. Which of the following exercise programs is the MOST appropriate for the client?

1) Isotonic Active exercise
2) Isometric exercise with resistance
3) Isotonic resistive exercise
4) Active Assisted exercise

Answer 1

Isotonic resistive exercise is the most suitable choice for a client with at least fair plus muscle strength and no range of motion limits, aiming to improve endurance and strength.

Step-by-step explanation:

Given that the client has no limits to range of motion and a muscle strength of at least fair plus, the most appropriate exercise program to improve endurance and strength would be Isotonic resistive exercise. This type of exercise combines movement (isotonic) with resistance, enhancing both muscular strength and endurance, as it recruits a higher ratio of FG fibers and results in hypertrophy of the muscle fibers. Isometric exercise with resistance would not involve movement, active assisted exercise is more suitable for those with less strength than fair plus, and isotonic active exercise wouldn't provide the resistance needed to increase muscle strength at the client's current level.

Aerobic exercises like cycling and brisk walking are mainly aimed at increasing cardiovascular endurance and less at increasing muscle mass and strength. Resistance exercises including weight training in particular promote muscle hypertrophy and increase muscle strength by engaging more fast-twitch muscle fibers.
