Results : The test-retest reliability of MNSI patient form was good (ICC = 0.830). For the examination part, the intratester was excellent (ICC = 0.905 to 0.931) and intertesters reliability was good (ICC = 0.780 to 0 . 869).
Conclusion : MNSI is a good screening tool for peripheral neuropathy. The Thai version has good reliability and is recommended to use in outpatient and community settings.
