Questions and Answers

What does the AROM assessment provide information about?

  • only coordination and motivation
  • only articular surfaces
  • only muscles, nerves, and tendons
  • articular surfaces, muscles, nerves, tendons, and coordination (correct)
  • What happens if pain appears during the AROM assessment?

  • It can indicate a problem with contraction, stretching, or pinching (correct)
  • It indicates a problem with coordination
  • It indicates a problem with contractile components only
  • It indicates a problem with non-contractile components only
  • What is the difference between AROM and PROM?

  • AROM relies on force and coordination while PROM does not (correct)
  • PROM only assesses articular surfaces while AROM assesses all components
  • AROM is passive while PROM is active
  • PROM is slightly greater than AROM
  • What is one of the factors that influence the range of motion?

    Study Notes

    Goniometer Alignment and Placement

    • Consists of potentiometer, fixed arm, and mobile arm
    • Bony references must be precisely located for accurate alignment
    • Proximal (fixed) arm: parallel to longitudinal axis of proximal segment
    • Distal (mobile) arm: parallel to longitudinal axis of distal segment
    • Fulcrum placement: on the movement axis of the assessed joint

    Measurement and Recording

    • Results recorded in X/0/Y system:
      • X: Flexion, Abduction, External Rotation, Supination
      • 0: Neutral position (reference)
      • Y: Extension, Adduction, Internal Rotation, Pronation
    • Effective angle: possible range of motion (angle) in each measurement
    • Functional angle: minimum range of motion (angle) required for joint functioning

    Other Measurement Devices

    • Measuring Tape and Ruler: measures distances and perimeters, requires bony or cutaneous references
    • Contours outlining: for measuring small joints

    Joint Mobility Assessment (JMA)

    • AROM (Active Range of Movement): provides information about articular surfaces, muscles, nerves, tendons, and coordination
    • PROM (Passive Range of Movement): slightly greater than AROM, provides information about articular surfaces
    • ROM influencing factors: age, position, gender, experience, BMI, day time, physical activity habits, warm up, professional occupation, leisure activities

    Goniometry

    • Measurement of a corporal segment related to another through a particular joint using graded devices
    • Examiner must know: subject position, required stabilisation, physiological final sensation
    • Procedure: bony prominences location, appropriate alignment/posture stabilisation, device proper alignment, segment displacement and end stop, device interpretation, right data registration

    Inclinometer

    • Gravity-dependent device comprising angle conveyor, pendulum needle (frontal + sagittal planes), and magnetic compass (horizontal plane)
    • Placed upon the distal segment
    • Not recommended for small joints, deformities, and swollen areas
    • Precautions to take using a compass: ask for pacemaker

    Electronic Goniometer

    • Used in research, appropriate for dynamic measurements
    • Requires accurate calibrations and subject positioning
