    Study Notes

    Joint Stability

    • Assessment includes evaluating the available range of motion (ROM) in joints.
    • Joint stability is inversely related to joint mobility, meaning increased stability results in decreased mobility, and vice versa.

    Joint Mobility

    • Range of Motion (ROM) refers to the degree of movement possible at a joint.
    • Limitations of Motion (LOM) can arise from injury, disease, trauma, or disuse.
    • Personal factors like age, obesity, developmental conditions, and injuries affect ROM.

    Evaluation of ROM

    • Goniometry is the standard measurement technique for assessing ROM objectively.
    • Both Active Range of Motion (AROM) and Passive Range of Motion (PROM) need to be assessed:
      • AROM: Client initiates movement, demonstrating control.
      • PROM: Therapist assists in moving the joint, assessing joint stability.

    Joint-End Feel

    • Describes the sensation experienced when a joint reaches its maximum PROM, indicating resistance to further movement.
    • Types of end-feel include soft, firm, and hard, each representing different joint conditions.

    Principles of Joint Measurement

    • Knowledge of average normal ROM and joint anatomy is crucial for accurate assessment.
    • Stability and proper positioning of the patient and therapist ensure effective measurement.
    • AROM measurements are obtained while avoiding compensatory movements from adjacent joints.

    Goniometry Assessment Procedure

    • Requires assessment of both sides of the body to establish a baseline for comparison.
    • Document movements in degrees and specify any signs of pain, swelling, or spasticity.
    • ROM results are categorized as:
      • WNL (Within Normal Limits): ROM within established norms.
      • WFL (Within Functional Limits): ROM may not be normal but allows for performance of daily activities.

    Functional Assessments

    • Informal assessments may be conducted before proceeding to formal measurements.
    • Observations can identify the need for more detailed analysis if limitations are present.

    Documentation

    • Goniometry results should be recorded with clear notation of joint positions and angles.
    • Detailed documentation aids in understanding and tracking progress over time.
