In this experimental study, ultrasound-guided incobotulinumtoxinA 10⁻30 U/muscle was injected into extensor carpi ulnaris, extensor digiti minimi, extensor digitorum longus and extensor carpi radialis brevis muscles. Pain (visual analogue scale [VAS], 0 to 10 [no pain to severe pain]) and upper-limb functionality (QuickDASH scale, 0 to 100 [best to worst]), assessed at baseline, 1, 3 and 6 months post-treatment, were analysed using repeated-measures analysis of variance (ANOVA) and Tukey post-hoc tests. Secondary analyses stratifying patient population by sex and baseline VAS were performed. Adverse events were reported. Twenty-four patients (mean [standard deviation] age 46.8 years) were included. Compared with baseline, mean VAS and QuickDASH scores improved at all follow-ups (penAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/botulinum toxin AincobotulinumtoxinAlateral epicondylitispainrehabilitationtennis elbowAdultBotulinum Toxins, Type AFemaleHumansMaleMiddle AgedMuscle WeaknessMuscle, SkeletalNeuromuscular AgentsPainTennis ElbowTreatment OutcomeUltrasonographyresearch article30650587open access10.3390/toxins110100462072-6651PMC6356468https://www.mdpi.com/2072-6651/11/1/46/pdf?version=1548122009https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6356468/pdf
