The Claim

In degenerative cervical myelopathy (DCM), smartphone-assessed motor performance correlates with standard clinical grading and with postoperative improvement.

Verified by Lenz ·

The Short Version

Available evidence supports the claim in broad terms. Peer-reviewed studies in DCM show smartphone-derived motor or mobility measures correlate with established clinical measures such as mJOA, VAS, and ODI, and some studies show these measures improve after surgery in parallel with clinical recovery. However, several findings are preliminary, some correlations are modest or inconsistent across scales, and early feasibility evidence was very small.

Caveats

  • The evidence does not show equally strong or consistent correlations across every clinical scale or every smartphone metric.
  • Some supporting studies are preliminary or small, including an early single-patient feasibility report, so generalizability is limited.
  • Correlation indicates association and tracking potential, not that smartphone measures can replace standard clinical assessment or prove causation.
