Clinical Scorecard: Evaluating the Predictive Value of Motor Evoked Potentials from Transcranial Magnetic Stimulation on Upper Limb Recovery: A Systematic Review

At a Glance

Key Highlights

• TMS-MEP predicts UL motor recovery with varying accuracy for muscle strength, synergies, and capacity.
• Sensitivity for muscle strength is 0.76; specificity is 0.96.
• UL-capacity shows the highest sensitivity at 0.84 and specificity at 0.91.
• Timing of TMS-MEP assessments does not significantly affect prognostic accuracy.
• Low risk of bias observed in included studies.

Guideline-Based Recommendations

Diagnosis

• Utilize TMS-MEP to assess prognostic outcomes for UL recovery.

Management

• Incorporate multimodal approaches combining clinical assessments with neurophysiological markers.

Monitoring & Follow-up

• Regularly evaluate UL function using TMS-MEP and clinical measures post-stroke.

Risks

• Limited accuracy in identifying individuals who will not regain UL function early post-stroke.

Patient & Prescribing Data

Individuals recovering from stroke with upper limb motor deficits.

TMS-MEP can guide rehabilitation strategies by predicting recovery potential.

Clinical Best Practices

• Assess TMS-MEP alongside clinical measures like the SAFE score.
• Conduct TMS-MEP assessments beyond the initial 3 months post-stroke for better prognostic accuracy.
• Ensure methodological rigor in TMS-MEP studies to enhance predictive validity.
