S3_L2: ROM Assessment Flashcards
It is the amount of movement (linear or angular) on each joint, and the extent of movement of a joint which is measured in the
degrees of a circle.
Range of Motion
Motion available in a joint in relation to the cardinal planes of the body
Freedom of Motion
The movement of shaft of bones resulting in motion
Osteokinematics
The motions of the bone surfaces within the joint
Arthrokinematics
The arc of motion produced by an individual’s muscle contraction assisted by an external force. The motion was initiated by the patient but due to limitations, the PT, pt’s opposite limb, or a machine finishes the movement.
Active Assistive ROM
The amount of motion attained by the examiner without assistance from the subject. This provides information on integrity of articular surfaces and extensibility of joint capsule, associated ligaments and muscles.
Passive ROM
The amount of motion attained by the subject in
unassisted voluntary joint motion. This is produced by active contraction of muscles crossing a joint and provides information on strength, coordination, functional ability, and willingness to move.
Active ROM
Small amount of available motions that occur within the joint that are not under voluntary
control which aids in protecting joint structures. This is determined by the joint capsule’s laxity and may be demonstrated passively but cannot be performed actively when doing mobilization of the joint.
Joint play
Characteristic feel of a joint felt by the examiner during assessment (passive movements). It is the resistance to further movement at the end of PROM and is determined by the structure of joint being tested.
Endfeel
Enumerate the 5 factors affecting ROM
- Age
- Gender
- Joint structures
- Occupation / lifestyle
- Dominance (Hand)
The ability of one or more joints to move beyond normal limits given the individual’s age and gender. This is due to laxity of soft tissues, abnormalities of joint surfaces or hereditary disorders.
Hypermobility
A decrease in ROM substantially less than normal. May be due to joint abnormalities, shortening of joint capsules or muscles, immobilization, neurologic conditions, or
prolonged immobilizations.
Hypomobility
Joint shape where one surface is convex and the other is concave
Ovoid joints
Joint shape where one surface is concave
in one direction and convex in one direction with
the opposing surface convex and concave
respectively.
Sellar (Saddle) joints
Movements patients can actively perform voluntarily that occur simultaneously together with accessory movements. This can result to either concentric or eccentric muscle contraction that moves a bone/joint.
Physiologic movements
Movements within the joint & surrounding tissues that are necessary for normal ROM and the manner in which one articulating joint surface moves relative to another. These cannot be voluntarily performed.
Accessory movements
Motions that accompany active motions but are
not under voluntary control
Component motions
Determine the corresponding descriptions of these accessory motions
- Often used in combination with joint mobilization to increase the stretch on the joint capsule
- The point does not touch the same point in the
ground twice - Decrease in space between two joint surfaces
- Same point on the moving surface creates an arc of a circle
- Surfaces are congruent; always in contact in the ground in different points
A. Roll
B.
Slide / Glide
C. Spin
D. Compression
E. Distraction
- E
- A
- D
- C
- B
TRUE OR FALSE: Spin does not occur by itself during a normal joint motion
True
Accessory motion known to add stability to a joint and known as a reaction of a joint during a muscle contraction.
Compression
Additional: Normal intermittent compressive loads could help move synovial fluids
What does gonia mean?
Angle
Aka finger goniometer
Joint specific goniometer
A 360 degree scale incorporated in a fluid filled
circular tube with air bubble that is strapped to limb segment being measured.
Fluid, Bubble or Hydrogoniometer
Most accurate non-goniometric instrument to measure ROM
Radiography (X-ray plates)
