Study Notes

Pt Positioning

Distal segment of the joint is placed in a desired position, considering gravity eliminated or resisted positions
Proximal segment must be stabilized through pt positioning, testing surface, or manual hold by the examiner

Stabilization

Muscle origin must be firmly fixed to prevent motion restriction
Begin with joint at the beginning of ROM
Optimize examiner's body mechanics
Ensure the patient can assume the position

Assessing Passive Range of Motion (PROM)

Assess the available anatomical joint ROM to rule out any inert barriers to movement that may impact MMT
Palpate and assess AROM (active range of motion)

Applying Resistance in MMT

Only apply resistance for MMT grades greater than 3
Use the break test, gradually increasing resistance from minimal to maximal
Hold resistance for 4-5 seconds
Apply resistance perpendicularly to the distal end of the distal segment being tested
Do not apply resistance further distally than the bone where the muscle inserts
Refer to Clarkson text for standard procedure
Apply resistance at the end of gravity-resisted ROM
