BACKGROUND: Chronic Achilles tendonitis is a painful condition generally caused by overuse and there are often unsatisfactory results with conservative treatment.
OBJECTIVE: The aim of the current study was to evaluate High Intensity Laser Therapy (class 4) in the treatment of chronic Achilles tendonitis. High intensity laser therapy is hypothesized to be effective and non-invasive therapeutic modality for this pathology.
DESIGN: The study was designed as a single blind. randomized control study.
SETTING: The study was conducted in a private rehabilitation facility ? Rehab Clinic Jarov during the time interval June 2012 ? May 2013.
PATIENTS: Fifty-one patients with chronic Achilles tendonitis were randomly assigned to a treatment group or a control group.
INTERVENTION: Both groups received equal therapy protocol consisting of 8 high intensity laser treatments over a period of 4 consecutive weeks. Placebo group received sham therapy with only navigation light emitted during the procedure.
MEASUREMENTS: Outcome measures were the visual analog scale (VAS). providing commonly used rating of pain intensity. and a standardized ADL questionnaire.
RESULTS: The statistical data analysis in both observed parameters suggest significantly higher efficacy in the HIL therapy group compared to placebo group at 4th and 12th week.
CONCLUSIONS: Patients diagnosed with CAT showed greater reduction in pain and improvement in ADL functional abilities after 8 high intensity laser treatment essions than did patients receiving placebo therapy. Based on the data analysis HIL herapy can be recommended as effective conservative clinical modality for chronic Achilles tendinopathy.
