Split hand index and ulnar to median ratio in Hirayama disease and amyotrophic lateral sclerosis [PDF]
Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration, 2017 We report the relative usefulness of split hand index (SHI) and ulnar to median (UM) ratio in Hirayama disease (HD) and amyotrophic lateral sclerosis (ALS).The patients with HD, ALS and matched controls were subjected to evaluation of UM ratio and SHI.

The senile hand: Age effects on intrinsic hand muscle
Muscle & Nerve, 2022 AbstractIntroduction/AimsAge can affect hand muscles non‐uniformly. We investigated the influence of age on the compound muscle action potential (CMAP) amplitude of the hand muscles and the derived split‐hand index (SHI).MethodsWe studied 244 subjects investigated for suspected myasthenia gravis but without neuromuscular disorders.

To determine the practical diagnostic utility of split-hand index (SI) values calculated from F-wave persistence (SIFP) and the F/M amplitude ratio (SIF/M) for differentiating patients with amyotrophic lateral sclerosis (ALS) from other conditions. Methods: This prospective study recruited consecutive patients from Peking Union Medical College Hospital,

Preferential wasting of the thenar muscles, the split-hand sign, may be used for early diagnosis of amyotrophic lateral sclerosis (ALS).Electronic databases were searched for studies assessing the split-hand index (SHI) and the compound muscle action potential (CMAP) amplitudes of abductor pollicis brevis (APB), first dorsal interosseous (FDI), and ...

Split-hand index for the diagnosis of amyotrophic lateral sclerosis
Clinical Neurophysiology, 2013Preferential wasting of the thenar group of muscles, the split hand sign, appears to be a specific feature of ALS. The present study developed a novel split-hand index (SI) and assessed its diagnostic utility in ALS.One hundred and seventy consecutive patients with neuromuscular symptoms (44 ALS, 126 patients with other neuromuscular disorders) were ...

The split-hand index (SI), a reliable diagnostic marker of amyotrophic lateral sclerosis (ALS), was prospectively assessed for differences across ALS subtypes and between the onset side of clinical symptoms or the dominant and contralateral sides. In addition, the prognostic utility of the SI was longitudinally assessed.Two hundred and forty-five ALS ...

In the arms of patients with Amyotrophic lateral sclerosis (ALS) two peculiar patterns of dissociated muscular atrophy have been described: the split-hand sign (with predominant atrophy of the lateral aspect of the hand, compared to hypothenar eminence) and the split-hand-plus sign (SHPS), a predominant abductor pollicis brevis (ABP) atrophy with ...
