Abstract:
BACKGROUND: Ultrasound-guided botulinum toxin type A injection is an effective treatment for spasticity. Euro-musculus spasticity approach is a new method for administering injections to the correct point of the correct muscle. The clinical outcomes of this practical approach are not vet available in the literature.
AIM: The purpose of this study was to evaluate the effects on spasticity and the functional outcomes of ultrasound guided botulinum toxin type A injections via the Euro-musculus spasticity approach to treat upper limb spasticity in post-stroke patients.
DESIGN: Observational study.
SETTING: Inpatient post-stroke patients.
POPULATION: Twenty-five post-stroke patients with post-stroke upper limb spasticity were recruited.
METHODS: The ultrasound-guided botulinum toxin type A injections were administered into the spastic target muscles using the Euro-musculus spasticity approach, and all of the patients were enrolled in rehabilitation programs after the injections. This research included the innervation zone and injection site figures and ultrasound images of each muscle in the upper limb. The degree of spasticity was assessed via the Modified Ashworth Scale and the upper limb motor function via the Fugl Meyer Upper Extremity Scale at the baseline and 4 and 12 weeks after the botulinum toxin type A injection.
RESULTS: Significant decreases in the Modified Ashworth Scale scores of the upper limb flexor muscle tone measured 4 and 12 weeks after the botulinum toxin type A injection were found when compared to the baseline scores (P<0.025). When compared with the baseline Fugl Meyer Upper Extremity subgroup scores, the sitting position, wrist and total scores at 4 and 12 weeks were significantly improved (P<0.025). However, only the Fugl Meyer Upper Extremity hand scores were significantly improved 12 weeks after the injection (P<0.025).
CONCLUSIONS: Ultrasound-guided botulinum toxin type A injection via the Euro-musculus spasticity approach is a practical and effective method for administering injections to the correct point of the correct muscle. Ultrasound-guided botulinum toxin type A injections combined with rehabilitation programs decrease spasticity and improve the upper extremity motor functions in stroke patients.
CLINICAL REHABILITATION IMPACT: This new approach for ultrasound-guided botulinum toxin type A injection is very practical and effective method for upper extremity spasticity.
