Letter to the Editor- "Correlation Between Core Muscle Endurance and Dynamic Balance in Silambam Practitioners"

Dear Editor, We read with great interest the recently published article by Muthu and Nisarudeen titled “Correlation Between Core Muscle Endurance and Dynamic Balance in Silambam Practitioners” [1]. The authors should be applauded for addressing an important and relevant topic in sports physiotherapy, particularly within traditional martial arts. However, we would like to highlight several methodological and statistical aspects that require clarification to improve the validity and clinical applicability of the findings. A cross-sectional correlational study design was used to examine the relationship between core muscle endurance and dynamic balance. While this design is appropriate for identifying associations, it does not allow causal interpretation, and conclusions suggesting improvement in balance or reduction in injury risk should be interpreted cautiously [2].
