A patient has "complete joint range of motion against gravity with moderate resistance." How would you grade this muscle strength and based on what point scale?
a. strength = 2, on a 5-point scale c. strength = 4, on a 5-point scale
b. strength = 3, on a 5-point scale d. strength = 5, on a 5-point scale
D
A patient with complete joint range of motion against gravity with moderate resistance has a muscle strength of 4 based on a 5-point scale. A muscle strength of 2 on a 5-point scale means that complete range of joint motion is possible only with the joint supported to eliminate the force of gravity and without any manual resistance. A muscle strength of 3 on a 5-point scale means complete range of joint motion is possible only without manual resistance. A muscle strength of 5 on a 5-point scale means complete range of joint motion against both gravity and full manual resistance.
