Chapter 9 ADL PROM Flashcards
Range of Motion (ROM)
the amount of movement available between any two bony levers and is commonly used as a measure of flexibility.
ROM vs Stretching
Stretching is a specific technique designed to increase a muscle’s available ROM.
ROM monitors and maintains the capacity for motion that already exists.
Changes in joint structure
may negatively affect the amount of available ROM
Osteokinematics
The movement of one bone in relation to another. The bone moving around a joint axis.
Arthrokinematics
describes the internal joint motion that makes the osteokinematic motion possible.
ROM exercises must be performed with attention to
both osteokinematics and arthrokinematics.
Planes of motion
ROM exercises are done in straight or diagonal planes of motion around a triplanar axis.
Straight Planes of joint motion
Sagittal plane - side to side
Coronal plane - front to back
Transverse plane - up to down.
Sagittal plane
Movements best observed from the sagittal plane
Flexion and extension: cervical, trunk, shoulder, elbow, wrist, fingers, hip, knee, toes
Thumb metacarpophalangeal (MCP) abduction and adduction
CMC abduction and adduction.
Frontal Coronal plane
Movements best observed from frontal plane
Abduction and adduction: shoulder, hip, fingers
Thumb carpometacarpal and MCP flexion and extension.
CMC flexion and extension
Transverse plane
Movements that rotate around a vertical axis.
Internal and external rotation: shoulder, hip, knee
Right and left rotation: cervical, trunk
Forearm supination and pronation
triplanar axis
joints such as ankle that cuts through all three planes
Diagonal planes or Vectored planes
Each diagonal motion combines the three straight planes into one movement that, in its full excursion, crosses the midline of the body. - some shoulder and hip movements (ball and socket)
proprioceptive neuromuscular facilitation (PNF) techniques
Types of stretching:
Hold-relax
Contract-relax
Hold-Relax-contract
Types of diagonal plane movement.
D1 Flexion: This pattern involves moving a limb from an extended position across the body to a flexed position. Imagine reaching up and across your body to grab something from a high shelf.
D1 Extension: The reverse of D1 Flexion, moving from a flexed position across the body to an extended position.
D2 Flexion: This pattern involves moving a limb from an extended position out to the side and up. Think of drawing a sword from a sheath on your opposite hip.
D2 Extension: The reverse of D2 Flexion, moving from a flexed position out to the side and down.
PNF pattern D1 UE
PNF pattern D2 UE
LE PNF patterns D1 and D2
Active Range of Motion (AROM)
When the force that moves a joint is generated internally.
Passive Range of Motion (PROM)
When the force moving the joint is generated externally.
(person, machine, gravity.)
Active Assisted Range of Motion (AAROM)
When portions of the movement are supplied acively and others are assisted external forces
Continuous Passive motion machine CPM
Used to be more common, but evidence suggests that while there may be benefits post-op there are no long-term benefits following total knee arthroplasty.
PROM benifits
Localized decrease in edema through changes in intra-articular joint pressure
Prevention of joint stiffness through decreased adhesion formation
Decreased articular cartilage erosion** why?
Decreased articular cartilage erosion from PROM why:
- Nutrient Distribution: Cartilage is avascular, meaning it doesn’t have its own blood supply. It relies on the movement of synovial fluid within the joint to receive nutrients and remove waste products. PROM exercises help circulate this fluid, ensuring that the cartilage gets the nutrients it needs to stay healthy12.
- Reduced Inflammation: Regular movement through PROM can help reduce inflammation in the joint. Inflammation is a key factor in cartilage erosion, as it can lead to the release of enzymes that break down cartilage3. By keeping the joint moving, PROM exercises can help minimize this inflammatory response.
- Maintaining Joint Mobility: PROM helps maintain the joint’s range of motion, preventing stiffness and ensuring that the cartilage surfaces move smoothly against each other. This can reduce the wear and tear on the cartilage, slowing down the erosion process1.
AROM additional benifits
- Come from muscle loading around the joint.
- Pressure loading on tendons
- Helps callogen in tendons.
- loading on tendons puts load on the bones.
- Load on the bones keeps them healthy.
- Loading on cartilage and synovium provides nureshment for joint structures.
- Promotes local circulation.
- Lymphatic and venous return.
- proprioception and kinesthesia
Lack of regular movement
Negative affects on joints and ultimatly decreased ROM through contractures.
PROM Indications
- As an assessment technique
- When the patient’s own muscle force is not sufficient to produce safe, effective motion at the joint.
- When active contraction of the muscles would be harmful to the patient
- As a means of educating the patient.
PROM contraindications
- If the patient declines consent
- During stages of tissue healing in which motion could inhibit, retard, or stop repair.
- When patients experience muscle guarding that is too strong for them to voluntarily overcome
- when strong muscle guarding is accompanied by increased pain.
