Dynamometry Flashcards
Active muscle insufficiency
When a two joint muscle contracts across both joints at the same time
Passive muscle insufficiency
When a two joint muscle is lengthened over both joints at same time
Handheld dynamometer
Assess grip strength
How many lbs greater is dominant hand grip strength vs non
5-10 lbs
What is grip strength recording in
pounds or kilograms
Isometric dynamometry
Measures static strength of muscle group with no movement
When is isometric dynamometry contraindicated?
fractures
HTN
Isokinetic dynamometry
Strength of muscle group at a constant predetermined speed
Will alter resistance to accomadate for change in length tension relationship
Make test
Patient applies force against dynometer
Break test
pt has to hold contraction against a pressure that is applied in opposite direction as contraction
