Protocol - Hemophilia Joint Health Score
The Hemophilia Joint Health Score (HJHS) 2.1 is a physiotherapist-administered assessment that measures the impact of bleeding on the elbows, knees, and ankles. The HJHS requires approximately 45-60 minutes to complete.
Although the Hemophilia Joint Health Score (HJHS) 2.1 has not yet been validated for adults, the guidance from the PhenX Hemophilia Inhibitor Research Working Group is that it is also appropriate for use in adult populations.
Summary of the Hemophilia Joint Health Score (HJHS) 2.1
The Hemophilia Joint Health Score (HJHS) 2.1 is a physiotherapist-administered assessment that takes approximately 45-60 minutes to complete. The HJHS measures the impact of recurrent bleeding on the elbows, knees, and ankles across 11 symptoms: swelling, duration of swelling, muscle atrophy, axial alignment, crepitus on motion, flexion loss, instability, joint pain, strength, and gait. Each of the 11 symptoms is rated on a Likert-style scale ranging from 0-1 to 0-4, with higher numbers indicating greater severity of symptoms. Scores from the individual items are added together to give a joint score, gait score, and a total score, with higher scores indicating greater joint damage.

Personnel and Training Required
The Hemophilia Joint Health Score (HJHS) 2.1 should be administered by experienced physiotherapists who have reviewed the training manual and instructional DVD. Training manual and DVD are available from the International Prophylaxis Study Group website (http://www.ipsg.ca/) by request.
Investigators will need the following:
- room with a sufficient source of lighting,
- goniometer (10 gradations are recommended),
- floor with a smooth firm surface,
- space to assess gait (walking, running), and
- set of stairs (nearby).
|Specialized requirements for biospecimen collection||No|
|Average time of greater than 15 minutes in an unaffected individual||Yes|
Mode of Administration
Infant, Toddler, Child, Adolescent, Adult, Senior, Pregnancy
Hemophilia patients on prophylaxis treatment ages 4 and older.
The Hemophilia Joint Health Score (HJHS) 2.1 is a valid, reliable, and widely used instrument that is sensitive to early joint changes in hemophilia patients on prophylaxis.

Joint Damage Assessment in Hemophilia Patients
May 7, 2019
A measure to assess joint damage resulting from bleeding in hemophilia patients.
This measure can be used to detect the early signs of joint damage and monitor the results of orthopedic and physiotherapy interventions in hemophilia patients treated with prophylaxis. Additionally, it can be used to track joint change over time and assess the efficacy of treatment regimens.
