ROM, Muscle Length Flashcards
ROM is motion available…
at any single joint
ROM is influence by…
bony structure surrounding ligaments joint capsule muscle SINS
Muscle length
ability of the muscles surrounding the joint to lengthen, allowing one joint or series of joints to move through the available ROM
Muscle length is referred to…
end range measurement of a muscle across the joint
How will muscle length affect ROM measurements?
muscles that pass over ONE joint only, ROM and length will be the same
muscles that pass over TWO joints, ROM of muscle length will be
Measuring muscle length (2 joint)
muscle needs to be elongated across all involved joints
Measuring joint ROM (2 joint)
uninvolved should be placed in shortened position
Kinematics
human movement without regard to the cause of the motion
Osteokinematics
Bone, quality and degree of motion observed of the whole bone
Result of Arthrokinematic motions
Sagittal, frontal, transverse movements around axis
Arthrokinematics
Joint, actual movement of the joint surfaces
Roll: rotary motion between joint surfaces
Slide: translation between the joint surfaces
ROM Procedure
1) explain procedure to patient
2) position patient in test position (ROM & muscle length is different)
3) stabilize the proximal joint segment
4) instruct the patient on the motion to be performed
5) palpate bony landmarks and take initial measurement
6) move patient through ROM
7) re-palpate bony landmarks and take end measurement
8) return to initial test position
9) record
AROM vs PROM
A: patient moves through
P: examinar moves patient
AROM advantages
allows the examiner to determine how much the patient is willing to move the joint being measured
observation of a functional task provides the examiner with info on multiple joints
PROM advantages
allows the examiner to determine the total ROM that patient possesses
provides the examiner with information to determine any limitations to full ROM, end feel
AROM vs. PROM
PROM usually more than AROM
same when there’s ligaments/capsules involved
AROM more than PROM when the patient guards
