Plain English Summary
Background and study aims
Haemophilia is an inherited condition that affects the blood's ability to clot, which can lead to bleeding into the joints and inflammation. The aim of this study is to assess the effectiveness, safety and tolerability of high-intensity laser therapy (HILT) for the treatment of joint inflammation in haemophiliac patients.
Who can participate?
Patients aged 18 and over with haemophilia A
What does the study involve?
All participants receive nine applications of HILT (three applications per week over 3 weeks). Pain is assessed before, during and after treatment.
What are the possible benefits and risks of participating?
It is not known for certain whether the participant will benefit, but as HILT is already used successfully in other diseases, it could help. The risks of HILT are the following reactions related to the application area: warm with possibly burning sensation, local sensitivity alteration, tingling, numbness, rush and oedema (build-up of fluid).
Where is the study run from?
IRCCS Ospedale Maggiore di Milano (Italy)
When is the study starting and how long is it expected to run for?
May 2011 to December 2011
Who is funding the study?
Who is the main contact?
Dr Michele Schino
To evaluate the efficacy, safety and tolerability of Hilterapia® (High Intensity Laser Therapy) in the chronic articular inflammatory processes in haemophilic adult patients: an interventional pilot multicentre study
Previous experimental studies (Fortune, 2002) indicate how the laser can be antagonistic to degenerative phenomenon, experimentally induced, to stimulate neo-chondrogenisis with formation of simil-jalina cartilage and to induce synovial hyperplasia; these effects appear to be particularly related to variations in light intensity (power intensity: W/cm2) rather than when supplied in doses (Joule J/cm2).

Therapy with the equipment ASA-SH1 involves 9 applications (3 applications per week x 3 weeks) of Hilterapia® with the following operating parameters:
1. Fluence: 360 to 760 mJ/cm2
2. Frequency: 10 - 35 Hz
3. Total energy: 500 to 1,500 J
4. Time of application: 6 - 11 minutes
Subjects will be requested to attend 10 clinical visits in total: T1 (screening/first treatment), T2-T9 (HILT application visits) and T10 (final visit).
Primary outcome measure
1. Pain will be measured using the Visual Analogue Scale (VAS) score (0 = no pain, 10 = unbearable pain) at baseline (T1), T4, T7 and T10 visits
2. Nieschls Score and the articular state will be measured using Hemophilia Joint Health Score 2.0
Secondary outcome measures
No secondary outcome measures
