Tóm tắt

 STUDY DESIGN: Diagnostic Study. OBJECTIVES: Early prognosis for recovery in traumatic cervical spinal cord injury resulting in tetraplegia may further guide rehabilitation and surgical interventions. This study assesses the feasibility and potential of using stimulated manual motor testing (SMMT) and needle electromyography (EMG) to predict gains in strength during acute inpatient rehabilitation. SETTING: Single academic inpatient rehabilitation facility (IRF). METHODS: Muscles with weak strength (manual motor test (MMT) <
 3) were assessed for lower motor neuron (LMN) integrity by SMMT using surface electrodes. Muscles without clinical strength (MMT=0) using SMMT and EMG. Correlations and prognostic models assessed the association and prediction of these measures with improvement in MMT values over 4 weeks. RESULTS: The missing data rate for SMMT and motor unit action potential (MUAP) testing was 9.5% and 24%, respectively. Wilcoxon Rank Sum tests of 4-week MMT changes with MUAP presence (P = 3.89×10 CONCLUSIONS: With pragmatic compromises in test administration to reduce attrition, measuring the presence of voluntary MUAP and improvement in SMMT during acute rehabilitation retains value in predicting motor improvement in 4 weeks.
