Detrusor muscle and sphincteric response to anorectal stimulation in spinal cord injury.

Twelve patients with spinal cord injuries were studied to determine whether the anal sphincter could be used as an index of urethral sphincter activity and to determine the bladder and striated sphincter response to anal and rectal stimulation. Electromyogram (emg) needle electrodes were placed in the external urethral sphincter, external anal sphincter and levator ani. The output of a cystometer was simultaneously recorded on the printout so that the relationship of the striated muscle response to distension of the bladder could be observed.

Isoenzyme distribution of creatine kinase and lactate dehydrogenase in serum and skeletal muscle in Duchenne muscular dystrophy, collagen disease, and other muscular disorders.

We determined the total activity and isoenzyme distribution of lactate dehydrogenase and creatine kinase in serum and biopsy specimens from skeletal muscle of nine normal individuals and nine patients with Duchenne muscular dystrophy (I), five with collagen disease (II), and four with non-progressive unclassified myopathy (III). Mean total serum creatine kinase in patients with Duchenne muscular dystrophy (867 U/liter, SD = 197) was 31-fold that in the control group (28 U/liter, SD = 14). There was also a small (3.

Electromyogram-gas cystometrogram: its use in the management of neurogenic bladder of spinal cord injury.

The electromyogram (emg)-gas cystometrogram was used to study spinal-cord-injured patients with indwelling catheters before trial of voiding (TOV) to remove an indwelling catheter. Twenty-four patients were studied during 27 consecutive admissions. A coaxial needle electrode was placed in the external urethral sphincter.

Lactate dehydrogenase isoenzyme levels in collagen disease.

Serum lactate dehydrogenase (LDH) isoenzymes were determined in 27 patients with collagen disease and 88 normal subjects. The mean value for LDH-3 isoenzyme was 20.4 +/- 3% in normal controls, 31.

Cervical orthoses effect on cervical spine motion: roentgenographic and goniometric method of study.

Movement of the cervical spine in the sagittal plane was studied in ten normal subjects from 20 to 30 years of age without and with four different cervical orthoses: (1) polyethylene Camp plastic collar with chin and occiput piece, (2) plastizote Philadelphia collar, (3) four-poster and (4) SOMI (sternal occipital mandibular immobilization). The effect of the orthoses on restricting sagittal motion was measured simultaneously using roentgenographic and bubble goniometric methods. The subject was immobilized in a straight back chair to eliminate trunk motion, and lateral cervical spine films were taken of each subject in neutral, flexion and extension without and with each orthotic device.
