Objective[edit | edit source]
The Harris Hip Scale (HHS) was developed for the assessment of the results of hip surgery, and is intended to evaluate various hip disabilities and methods of treatment in an adult population. The original version was published 1969. The HHS is an outcome measure administered by a qualified health care professional, such as a physician or a physical therapist.
Intended Population[edit | edit source]
Method of Use[edit | edit source]
No training is required to administer the HHS and it requires very little time or equipment (goniometer, plinth) to complete. There are ten items covering four domains. The domains are pain, function, absence of deformity, and range of motion.
The pain domain measures pain severity and its effect on activities and need for pain medication. The function domain is divided into daily activities and gait. The deformity domains observes hip flexion, adduction, internal rotation, and extremity length discrepancy while the range of motion domain asses hip ROM.
The HHS is divided into three sections. The first section are questions about pain and its impact which are answered by the patient or client. The second and third sections require the physiotherapist to assess the patient or client's hip joint and function.
The HHS is a measure of dysfunction so the higher the score, the better the outcome for the individual. Results can be recorded and calculated online. The maximum score possible is 100. Results can be interpreted with the following: <70 = poor result; 70–80 = fair, 80–90 = good, and 90–100 = excellent.
Evidence[edit | edit source]
Reliability[edit | edit source]
Test-retest reliability is "excellent" for both physicians (r = 0.94) and physiotherapists (r = 0.95) with an interval of three to for weeks.
Validity[edit | edit source]
In terms of content validity, The HHS has demonstrated no major differences when tested against the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Short Form 36 (SF-36).
When assessing for construct validity, the pain and function domains in HHS have been shown to correlate with similar domains in the WOMAC, Nottingham Health Profile, and the SF‐36, particularly the physical (but not mental) domains of the SF-36.
Responsiveness[edit | edit source]
Wamper et al report unacceptable ceiling effects in 31 of 59 studies. Pooled data across the studies included (n = 6,667 patients) suggested ceiling effects of 20% (95% confidence interval 18–22).
In a study of 335 THRs, Shi et al found the HHS was responsive to pain and function at six months post-operatively but week at the two year follow up.
