Summary

What it measures:

Assesses self-reported functional status of those with musculoskeletal hip disorders.¹

• 28-item assessment that is divided into 2 subscales: activities of daily living (HOS-ADL) and sports-related activities (HOS-SRA or HOS-Sports)
  • HOS-ADL subscale: 19 items
  • HOS-Sports subscale: 9 items; higher-level activities
• HOS has been translated and culturally adapted to many languages.

Type of measurement: Patient-reported outcome

International Classification of Functioning, Disability and Health (ICF)

Domains

• Activities
• Participation

Categories

• Recreation and Leisure
• Mobility: Walking and Moving Around
• Changing and Maintaining Body Position
• Carrying, Moving, and Handling Objects
• Self-Care

Target Population:

• Nonarthritic hip joint pain
• Labral tear¹
• Hip arthroscopy^2,3

Taskforce Recommendations

A Grade A recommendation from the Hip Pain and Movement Dysfunction Associated With Nonarthritic Hip Joint Pain is to use a patient-reported outcome measure, such as the HOS, at baseline and at least one other follow-up point to assess activity limitations and participation restrictions.

Clinical insights

• The HOS is relatively quick to administer and takes simple math calculations to properly score the test. Clinically, it does take more time to administer and score than other tests, but it has other advantages.
• In the less active population, just the HOS-ADL portion of the test could be utilized. HOS-ADL has a high ceiling effect.
• HOS-Sports does not have a floor effect or ceiling effect.
• The ability to utilize this test in both low and high-level populations, and the ability to score the HOS-ADL and HOS-Sports subscales independently, makes this test a versatile tool that can be used for a wide variety of patient populations and to provide an accurate representation of their current level of function in the context of their prior level of function.
• It is best to use in a population with nonarthritic hip pain, labral tears, or post hip arthroscopy. This test has not been validated for hip pain related to arthritis or other hip pathologies or surgeries.
