Quantitative Assessment of Stereotactic and Functional Neurosurgery

“…These results confirmed the findings of Sherring ton [19] and Lowenthal and Horsley [ 11], Despite some negative results [23], these findings have been confirmed in many studies of evoked potentials [10,18,21,25], developmental reflexes [17] or movement [13,14,21,25]. Neurophysiological studies in patients undergoing cerebel lar stimulation included the assessment of H reflexes [8,12,15,21], V| responses, V2 responses, blink reflexes, cortical and subcortical somato sensory evoked potentials, auditory evoked potentials, videomonitor ing and EEG recordings [20]. This paper will concentrate on the value of cortical and subcortical somatosensory evoked potentials and auto matic gait analysis in the assessment of the effects of stereotactic and functional neurosurgical techniques in man.…”

Ballistic elbow flexion movements in patients with amyotrophic lateral sclerosis.

“…Prolongation of the first agonist burst was seen in a rapid shoulder abduction movement in a patient with a traumatic cerebral injury (Angel, 1975). In rapid alternating movement tasks patients with spasticity of varying aetiology moved more slowly than normal, and the EMG burst durations when measured were prolonged (Neilson, 1972;Sahrman and Norton, 1977;McLellan et al, 1978).…”

Stereotactic Surgery of Abnormal Movements: Clinical Results in 33 Cerebral Palsy Patients

“…Spasticity, on the other hand, calls for other functional neurosurgery procedures, such as medullary or cerebellar stimulation [14,16,17,19,20]. The most spe cific indication proved to be unilateral motor impairment, in which an improvement in function was also obtained.…”
