Comparing the Modified Ashworth scale and Tardieu scale with h/m ratio for assessing biceps spasticity in post stroke individuals – A cross-sectional study

Background: Among the most reliable tools for assessing spasticity in stroke patients are the Modified Ashworth Scale (MAS), the Tardieu Scale, and the H/M ratio. Method: A cross-sectional study was conducted on 30 post-stroke individuals aged over 30 years. Spasticity of the biceps muscle was assessed using MAS, Tardieu Scale and H/M ratio. Results: Pearson’s correlation coefficient was used to analyse the relationships among the three assessment techniques. The results demonstrated a strong positive correlation between MAS and the Tardieu Scale (r = 0.756) and between the Tardieu Scale and the H/M ratio (r = 0.665). A moderate correlation was observed between the H/M ratio and MAS (r = 0.400). Conclusion: The study concludes that both MAS and the Tardieu Scale show a positive correlation with the H/M ratio. However, the Tardieu Scale demonstrates a stronger correlation. Keywords: Hypertonia, Cerebro vascular Accidents, Assessment, H reflex, M wave
