Harris Hip score - SF36
The aim of this study was to investigate the effect of botulinum toxin type A injection into the adductor muscles in reducing pain and improving joint
mobility and quality of life in patients affected by hip osteoarthritis. METHODS:
A total of 39 outpatients, mean age 68 years
(age range 41-82 years), were
evaluated using the Harris Hip Score to test hip function, a visual analogue
scale to measure pain intensity and the Short Form 36 (SF-36) questionnaire to
assess patient well-being and quality of life at baseline, 2, 4
and 12 weeks
after treatment with botulinum toxin type A. A total of 400 U of botulinum toxin
type A (Dysport) was injected into the adductor longus muscle and the adductor
magnus muscle. RESULTS:
The Harris Hip Score increased significantly after 2, 4
and 12 weeks (df 3, chi2 = 45.1; p < 0.0001). A significant decrease in pain
intensity was detected at all the follow-up visits, after 2, 4 and 12 weeks (df
3; chi2 = 27.8; p < 0.001). The SF-36 score was significantly higher 4 and 12
weeks after treatment.
At each evaluation visit a significant correlation was
detected between decreased pain and improved hip mobility. CONCLUSION: Botulinum
toxin type A induced a reduction in pain, indicating that this might be an
innovative, less invasive treatment in patients affected by severe hip
osteoarthritis, with remarkable effects on the clinical management of this disease.
