Publikováno v: Muscle & Nerve. 32:35-42
To quantitate improvement in hand-grip myotonia and muscle strength (i.e., the “warm-up” phenomenon) in myotonic dystrophy type 1 (DM1), six successive, standardized maximum voluntary isometric contractions (MVICs) were recorded on 2 separate day

Accuracy of motor responses in subjects with and without control of antagonist muscle
Autor: A. W. Wiegner, M. M. Wierzbicka
Publikováno v: Journal of Neurophysiology. 75:2533-2541
1. The aim of this study was to investigate the role of the antagonist muscle in determining the accuracy of fast, single-joint motor responses to a target. We recently found that C5/C6 tetraplegic subjects, who lacked voluntary control of their tric

Discharge properties of single motor units in patients with spinal cord injuries
Autor: M. Margaret Wierzbicka, Llewelyn Davies, Allen W. Wiegner, Robert R. Young
Publikováno v: Muscle & Nerve. 16:661-671
To study neurophysiological correlates of spastic paresis, we analyzed the discharge pattern of single motor units (SMUs) during sustained voluntary contraction from muscles weakened by spinal cord injury (SCI) and from muscle of near normal strength

Evoked myotonia can be 'dialed-up' by increasing stimulus train length in myotonic dystrophy type 1
Autor: Eric L. Logigian, Chad Heatwole, Richard T. Moxley, Paul Twydell, Nuran Dilek, Allen W. Wiegner, Chris Quinn, William B. Martens, Charles A. Thornton
Publikováno v: Muscle & Nerve.
It is unknown how evoked myotonia varies with stimulus frequency or train length, or how it compares to voluntary myotonia in myotonic dystrophy type 1 (DM1). First dorsal interosseous (FDI) tetanic contractions evoked by trains of 10-20 ulnar nerve

Abnormal most-rapid isometric contractions in patients with Parkinson's disease
Autor: Robert R. Young, M. Margaret Wierzbicka, Allen W. Wiegner, Eric L. Logigian
Publikováno v: Journal of Neurology, Neurosurgery & Psychiatry. 54:210-216
Fast isometric elbow flexor muscle contractions of specified amplitude in six normal subjects were compared with those of 11 patients with Parkinson's disease. Despite treatment, all patients exhibited deficits in this motor task. Three patients were

Computerized hand grip myometry reliably measures myotonia and muscle strength in myotonic dystrophy (DM1)
Autor: Richard T. Moxley, Eric L. Logigian, William B. Martens, Chris L. Annis, Shree Pandya, Cheryl A. Barbieri, Nuran Dilek, Allen W. Wiegner, Charles A. Thornton
Publikováno v: Musclenerve. 36(3)
The aim of this study was to develop a reliable, sensitive, quantitative measure of grip myotonia and strength and to determine whether CTG repeat length is correlated with grip myotonia and with muscle strength in myotonic dystrophy type 1 (DM1). Th

Publikováno v: Cardiovascular research. 32(6)
Objective: To examine the basis for local wall motion abnormalities commonly seen in patients with ischemic heart disease, computer-controlled isolated muscle studies were carried out. Methods: Force patterns of physiologically sequenced contractions
