Response to: “Sarcopenia and Back Muscle Degeneration as Risk Factors for Back Pain: A Comparative Study”

摘要

Question: The Asian Spine Journal recently published an article in volume 14(3), 2020 by Kim et al. [1] “Sarcopenia and back muscle degeneration as risk factors for back pain: a comparative study.” The authors have read the article with great interest. The introduction is well written. Also, the author had well explained about degree of back pain association with back muscle degeneration than with sarcopenia. They developed back muscle degeneration risk index, indicating it to be a useful parameter for evaluation of back pain and muscle degeneration. We gathered valuable information and congratulate the authors for this. However, there are some issues, which needs clarification.
