Study on correlation between SWE hardness measurement of calf muscle and MNSI score in patients with diabetes mellitus

Objective To analyze the correlation between shear wave elastography (SWE) hardness measurements of calf muscle in diabetic mellitus patients and Michigan neuropathy screening instrument (MNSI) score. Methods A total of 102 patients with diabetes mellitus who were hospitalized in Lianyungang Hospital of Traditional Chinese Medicine from August 2020 to February 2022 were selected as study object. According to MNSI score, diabetes mellitus patients were divided into group A (0 points ≤MNSI score ≤1 point, 20 cases), group B (1 point < MNSI score≤2 points, 32 cases), group C (2 points < MNSI score≤3 points, 26 cases) and group D (3 points < MNSI score≤4 points, 24 cases). Thirty normal volunteers were selected as control group. The values of Young modulus of calf gastrocnemius, tibialis anterior and peroneus were measured by SWE and compared under different tension states. Spearman correlation test was used to examine the relationship between MNSI score and Young modulus of calf muscle. Results With the increase of MNSI score, the Young modulus of each calf muscle shear wave decreased in all groups, and the differences between groups were statistically significant (P<0.05). Young modulus of maximum plantar flexion of gastrocnemius, maximum dorsiflexion of gastrocnemius, maximum plantar flexion of tibialis anterior and peroneus foot varus in diabetic patients were negatively correlated with MNSI score (P<0.05), and the correlation coefficients were –0.74, –0.73, –0.72 and –0.75, respectively. Conclusion With the aggravation of peripheral neuropathy in diabetes mellitus patients and the decrease of shear wave hardness of calf muscle, SWE can comprehensively evaluate diabetic peripheral neuropathy with MNSI score.
