AI Article Synopsis
- The study aimed to understand how the thickness of hand muscles measured by ultrasound relates to hand strength in patients who had nerve reconstruction.
- Researchers measured muscle thickness using ultrasound and assessed hand strength with specialized tools like a dynamometer and pinchmeter in a group of patients.
- Results showed significant correlations between muscle thickness and hand strength, suggesting ultrasound could be an effective method for monitoring patients with nerve injuries.
Article Abstract
Introduction: The aim of this study was to assess the relationship between ultrasonographic hand muscle thickness measurements and hand muscle strength in patients who underwent median or ulnar nerve reconstruction.
Methods: In this prospective, cross-sectional study, intrinsic hand muscle thicknesses were measured using ultrasound with a 4- to 13-MHz linear-array probe. Measurements of hand strength were performed using a dynamometer and a pinchmeter.
Results: In the median nerve group (n = 11), a moderate correlation (r = 0.694; P = .018) was observed between lateral pinch strength and transverse thenar thickness. In the ulnar nerve group (n = 11), longitudinal thenar thickness below the flexor pollicis longus tendon was moderate to highly correlated with pinch and handgrip strengths (r = 0.726-0.893; P < .05); whole transverse thenar thickness was moderate to highly correlated with pinch strengths (r = 0.724-0.836; P < .05).
Discussion: Sonographic measurements of intrinsic hand muscle thickness may be a useful tool for the assessment and follow-up of patients with median or ulnar nerve injury.
