Ultrasound Evaluation of Upper Limb Sublesional Muscle Morphology in Cervical Spinal Cord Injury.

ABSTRACT:

Introduction/aims

Upper limb paralysis is arguably the most limiting consequence of cervical spinal cord injury (cSCI). There is limited knowledge regarding the early structural changes of muscles implicated in grasp/pinch function and upper extremity nerve transfer surgeries. We evaluated: (1) muscle size and echo intensity (EI) in subacute cSCI (2-6 months) and (2) the influence of lower motor neuron (LMN) damage on these ultrasound parameters.

Methods

Cross-sectional B-mode images were captured bilaterally in individuals with cSCI (injury duration: 3.3 ± 1.2 months; C4-C6 injury levels; American Spinal Injuries Association Impairment Scale A-C; 45.7 ± 13.7 years; 3 females, 14 males) for biceps brachii (BB), extensor carpi ulnaris, extensor indicis proprius, flexor pollic
