Evaluation of the Effectiveness of Treatment with Botulinum Toxin on Sleep Quality in Stroke-Related Spasticity
MetadataShow full item record
Background and purpose: Botulinum toxin (BoNT) is a commonly used agent in the treatment of stroke-related spasticity. Sleep disorders can often be seen as a comorbidity or complication in stroke patients. Based on the data that spasticity is associated with sleep disorders, in this study, we aimed to evaluate whether sleep quality has changed in patients with stroke treated with BoNT. Methods: Thirty five (17 female / 18 male) stroke patients with gastrocnemius and / or soleus spasticity were included in this observational cross-sectional study. In clinical evaluation before and three months after BoNT injection; for spasticity evaluation modified Ashworth scale (MAS), pain assessment visual analog scale (VAS), functional evaluation; passive joint range of motion (ROM) measurement, functional independence measurement (FIM), lower limb Brunstrom staging, life quality assessment short form-36 (SF-36) quality of life scale, and sleep quality assessment Pittsburgh sleep quality index (PSQI) scales were used. Results: After the BoNT injection, there was a statistically significant decrease in MAS and VAS scores, a significant increase in passive ROM measurements, FIM, lower limb Brunstrom staging, and SF-36 physical function sub parameter. There was also a significant decrease in PSQI scores. Before and after treatment, there was no correlation found between PSQI values with pain and spasticity. However, there was a weak negative correlation between post-treatment PSQI values, passive ROM, SF-36 physical function and SF36 physical role sub parameters (respectively: r:-0.335 p: 0.049, r:-0.364, 0.032, r:-0.404, p: 0.016). Conlusion: The results of our study suggest that BoNT, which is frequently used in the treatment of spasticity in stroke patients, has positive effects on (c) 2020 Elsevier Inc. All rights reserved.
