Range of motion Flashcards
What is joint ROM?
the amount of movement that is possible at a joint. The arc of motion on a specific plane.
What is PROM?
Passive range of motion - movement applied to a joint from an outside force
What is AROM?
Active range of motion - movement of a joint provided entirely by the muscles acting on a joint to perform an exercise.
True or false: AROM is greater than PROM in a normal individual?
False, PROM is greater than AROM
How is ROM tested?
- Functional motion test
- screening tests
- measuring joint ROM with goniometer
Name 3 ROM contraindications
- Joint dislocations
- Unhealed fracture
- Immediately after surgery
- Presence of myositis ossificans (bone tissue develops in muscle after injury
- When ectopic ossification is a possibility (new bone forming in tissues that do not usually ossify).
Name 3 ROM precautions
- Joint inflammation or infection
- Taking medication for pain or muscle relaxants
- Osteoporosis, hypermobility or subluxation of a joint
- Haemophilia
- Haematoma
- Just sustained an injury to soft tissue
- Newly united fracture
- Undergone prolonged immobilisation
- Bony ankylosis suspected (stiffness of a joint due to abnormal adhesion and rigidity of bones of the joint due to injury or disease.
- Carcinoma (cancer) of the bone or any fragile bone condition
What is normal end feel?
Normal – full ROM achieved, motion limited by normal anatomical structures
Why is ROM measurement useful?
- identifies limitations that interfere with function or may produce deformity.
- identifies additional motion needed to increase functional capacity or reduce deformity.
- identifies the need for assistive devices or splints and progression of treatment.
What is hard end-feel?
Bone hits bone
What is firm end feel?
A stretching or spring feel
What is soft end feel?
When soft tissue hits soft tissue
Name 3 causes of limitation of ROM during occupations
- Shortening if soft tissue (muscle, tendon, ligaments, skin)
- Inflammation, oedema, haemotoma
- Localised destruction of bone - arthritis
- Amputation
- Congenital abnormalities
- Acute and chronic pain
- Maladaptive environmental conditions
What 5 features do you look for when assessing ROM?
- Compensatory movement
- Posture
- Muscle contours
- Skin – colour or condition
- Compare with contralateral (non-injured side) parts
What are the 4 uses of palpation?
- Assess bony/soft tissue contours, skin temperature and texture
2, Locate bony landmarks to align goniometer - Determine presence or absence of muscle contraction
- Identify soft/bony tissue irregularities
