Cervical dystonia (CD) is characterized by pain, which is often the main reason for visiting a doctor. Analgesics are often used to control pain, but regular administration of botulinum toxin type A (BTA) may be more effective. The effectiveness of regular long-term use of BTA in CD in relation to pain has been little studied, which served as the basis for this study.
For 3 years, 65 patients (44 men, 21 women, average age 53±15 years) with CD who regularly received BTA therapy were observed. The severity of CD was assessed using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), pain — using TWSTRS and a Numeric Rating Scale (NRS) at baseline, one month after BTA therapy and 3 years later during the period of maximum severity of symptoms (before the next BTA injection).
A decrease in pain according to NRS and TWSTRS was shown not only after 1 month, but also after 3 years (p<0.0001). The reduction in pain was significant for initially moderate and severe pain according to the NRS of pain (p<0.0001). In patients with mild pain intensity, no significant changes were noted (F=1.5, p=0.23). An inverse correlation was noted between the sensory trick and the duration of the disease.
The use of BTA for CD reduces pain not only after a month, but also after 3 years of regular therapy during the period of maximum severity of symptoms.
