Reassessing the Diagnostic Utility of the Split Hand Index in Amyotrophic Lateral Sclerosis Patients—The Divide by Zero Problem [PDF]

Neurology International, 2022
We set out to assess the diagnostic utility of the split hand index (SHI) for amyotrophic lateral sclerosis (ALS) and also to see if and how it can be applied to severely atrophied muscles, a frequent finding in this setting. We enrolled 38 patients from

Split hand syndrome and the split hand index in ALS patients [PDF]

Romanian Journal of Neurology, 2018
Our objective has been a review of the recent data available in reference to the split hand clinical sign in amyotrophic lateral sclerosis (ALS) and its novel electrophysiological counterpart the split hand index (SHI).

Evaluation of F wave and split hand index in patients with amyotrophic lateral sclerosis [PDF]

The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2020
Background Amyotrophic lateral sclerosis (ALS) is characterized by gradual disturbance of both upper and lower motor neurons (LMN). In ALS, muscle wasting favors the abductor pollicis brevis (APB) and first dorsal interosseous (FDI), with relative ...

Exploring the split hand phenomenon with the neurophysiological index

Neurophysiologie Clinique, 2023
In 164 subjects of different age groups, we studied the neurophysiological index (NI) ([CMAP amplitude/Distal motor latency] *[F-wave frequency]; CMAP=compound muscle action potential) for three hand muscles (APB= abductor pollicis brevis; FDI= first dorsal interosseous; ADM= abductor digiti minimi). A split hand index based on CMAP amplitude (SHI_CMAP)

Utility of split hand index with different motor unit number estimation techniques in ALS

Clinical Neurophysiology, 2023
Utility of the split hand index (SI) in amyotrophic lateral sclerosis (ALS) has been reported when using the compound muscle action potential (CMAP) amplitude method (SICMAP amp). A motor unit number index (MUNIX) based SI method (SIMUNIX) was purported to exhibit higher sensitivity.

Hirayama disease: an uncommon cause of motor neuron disease [PDF]

Arquivos de Neuro-Psiquiatria
We herein report the case of a 23-year-old man with a 3-year history of progressive right-hand weakness, leading to functional impairment. A neurological examination revealed signs of lower cervical motor neuron involvement, including the reverse split ...

Split hand muscle echo intensity index as a reliable imaging marker for differential diagnosis of amyotrophic lateral sclerosis

Journal of Neurology, Neurosurgery and Psychiatry, 2018
ObjectiveThe objective of this study was to investigate the usefulness of muscle ultrasound in evaluating dissociated small hand muscle atrophy, termed ‘split hand’, and its feasibility in the diagnosis of amyotrophic lateral sclerosis (ALS).MethodsForty-four patients with ALS, 18 normal subjects and 9 patients with other neuromuscular disorders were ...

The Sensitivity and Specificity of Split-Hand Index Using Muscle Sonography

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2022
ABSTRACT:Background:The split-hand index (SHI) (first dorsal interosseous (FDI) × abductor pollicis brevis (APB)/abductor digiti minimi muscle (ADM)) has been suggested as a useful measure for amyotrophic lateral sclerosis (ALS) diagnosis, using electrophysiological and sonographic indices.
