Evaluating the Effects of Botulinum Toxin Injection and Physiotherapy on Post-Stroke Patients During One Year Observation - a Pilot Study

Abstract

Introduction: Stroke is a serious health problem in the modern population. Spasticity is one of the consequences of stroke and affects about 30% of people. Increased muscle tone affects postural control disorders. Due to the specificity of spasticity, therapy in post-stroke patients is a challenge for neurological physiotherapy. Therefore, it requires the development of appropriate management standards .Study aim: The aim of the study was to evaluate the effectiveness of 3 combination therapy cycles based on botulinum toxin injection and physiotherapy for muscle tone, muscle strength and postural stability in post-stroke patients qualified for the spasticity treatment programme of the lower and upper limbs.Material and methods: The pilot study involved 12 patients (6 from the lower limb and 6 from the upper limb programme). The 1-year combination therapy programmes included 3 botulinum toxin injections and 3 weeks of physiotherapy after each injection. Clinical evaluation was conducted before and after the 1-year observation cycle. The results were evaluated using: MAS (Modified Ashworth Scale), MRC (Medical Research Council Scale) and posture stability test on a balance platform (BiodexSD).Results: A decrease was observed in muscle tone of the lower and upper limbs, as well as an increase in muscular strength of the upper limb. However, there were no noted statistical significance of the studied parameters.Conclusions: Physiotherapy in combination with the botulinum toxin is an important element of improvement in post-stroke patients. However, further research is needed to explicitly confirm its effectiveness.
