Measurement of hertzian waves capture at body surface in patients with traumatic paraplegia.

Using an original method--the Biohertzmetry--the level of hertzian waves capture at body surface was measured in 20 patients with traumatic paraplegia. A statistically significant decrease of the hertzian waves capture level in the toes in comparison with the proximal area has been noted in 12 patients with complete spinal cord lesion. In patients presenting an open or cicatricial decubitus ulcer, at scar level, in the surrounding skin area with modified colour--and even in a contiguous few millimeters large skin strip normally coloured,--a marked decrease of the level of hertzian waves capture in comparison with the healthy skin ares situated off the decubitus ulcers has been pointed out.

Exogenous precipitating factors in stroke.

We studied in 300 stroke patients (100 carotid ischemic, 100 vertebrobasilar ischemic, and 100 hemorrhagic) the precipitating factors (PF) of stroke. Precipitating factors were observed in 63.7% of cases.

[Number agraphia].

One hundred and seventy-five aphasic patients (50 total, 50 mixed, 50 motor-amnesic and 25 sensory-amnesic aphasics) were tested for the writing to dictation of numbers with more than one digit. Twelve types of error were found. The percentages for the different types of error were determined for all subtypes of aphasic patients and for the total group of patients.

Quantitative studies on speech characteristics of aphasics. A statistical approach to vocabulary.

The paper presents a linguistic-statistical study of the vocabulary and word-frequency as well as of the variety and frequency distribution of the parts of speech. Ten aphasics were studied in comparison with 10 normal controls. A corpus of 2,500 words was collected in each subject by means of a standard-interview.
