Semi-quantitative EMG methods are in common use in clinical electromyography laboratories but have a number of drawbacks and limitations, including examiner bias in MUP analysis and challenges distinguishing between MUP categories of normal and neurogenic and normal and myopathic waveforms. An array of formal MUP quantitation methods has been developed in recent decades, which seek to address many of the shortcomings of semiquantitative EMG. The advantages of quantitative EMG (QEMG) include: (1) making measurements of MUP recordings consisting of numerical values derived from precise measurements, (2) generating normative data and allowing comparisons with data from patients with suspected neuromuscular diseases, (3) allowing for reproducible results that can be compared at different times by different examiners and in different labs, and (4) allowing accurate assessment of improvement or deterioration in disease severity over time.

Neurogenic Lesions

Aims. In this study we analyzed the degree of genetic homozygosity among spina bifida patients with different degrees of neurogenic lesion (N = 82), as well as their clinical and neurological characteristics, compared to healthy control individuals (N = 100). Methods. According to clinical and electromyographic findings, we separately assessed the type of neurogenic lesion (paresis or paralysis). Regarding the degree of neurogenic lesion, patients were classified into three groups: mild, moderate and severe. We analyzed six muscles. For assessing the degree of individual genetic homozygosity, we tested the presence and distribution of 15 homozygous recessive characteristics (HRC). Results. The predominant type of neurogenic lesion was paresis. Every third evaluated muscle was affected in the group with mild neurogenic lesion, while more than half were affected in the group with severe neurogenic lesion. The average values of HRCs among different groups of patients and the control showed the population-genetic differences that exist among them (control x ¯ HRC/15 = 3.0 ± 0.2; mild x ¯ HRC/15 = 3.6 ± 0.2; moderate x ¯ HRC/15 = 4.8 ± 0.3; severe neurogenic lesion x ¯ HRC/15 = 5.0 ± 0.3). Conclusions. Spina bifida patients have a significant increase of recessive homozygosity and a decreased variability compared to the control group. As neurogenic lesions are more severe, more affected muscles are present, as well as the increase of individual recessive homozygosity.
