Grip Strength as a Screening Index for Severe Degenerative Cervical Myelopathy in Primary Care: Development of Cutoff Values Using Receiver Operating Curve Analysis.

Grip strength had moderate-to-high diagnostic accuracy for DCM between participants in the control and DCM groups. We developed easily applicable cutoff values for primary care DCM screening with ≥90% sensitivity. In patients with sarcopenia, DCM should be differentially diagnosed in primary care.
