Area of Science:

  • Rheumatology
  • Orthopedics
  • Primary Care Screening

Background:

  • Locomotor system examination is often overlooked in clinical practice.
  • The Gait, Arms, Legs, Spine (GALS) screen offers a practical approach to identify functional problems.
  • Existing health status measures are used to validate new screening tools.

Purpose of the Study:

  • To evaluate the GALS screen's ability to reflect functional impairment.
  • To compare GALS findings with established health status measures.
  • To assess the reliability and validity of the GALS screen in diverse musculoskeletal conditions.

Main Methods:

  • Two observers conducted the GALS screen on 83 patients with various musculoskeletal diseases.
  • GALS components were scored on a 0-3 scale.

  • Functional ability was assessed using the Health Activity Questionnaire (HAQ), Barthel index, and Steinbrocker's ARA classification.

    • Main Results:

    • Strong correlations were observed between GALS scores and functional indices (r = 0.62–0.71, p < 0.001) for the overall group.
    • Similar strong correlations were found in rheumatoid arthritis patients (r = 0.65–0.70, p < 0.001).
    • Inter-observer agreement was high, with proportional agreement >70% and kappa statistics (k) ranging from 0.49 to 0.74.

    Conclusions:

    • The GALS screen is a reliable and valid tool for assessing functional ability in patients with musculoskeletal diseases.
    • The GALS screen demonstrates effectiveness when compared to standard, accepted indices.
    • The findings support the use of the GALS screen as a screening test for general practitioners and medical students.
