That can cause muscle spasms as well as neck pressure.
Rear tests use a dummy that measures neck pressure; the test simulates a collision where a stationary vehicle is struck from behind at 20 mph.
The side effects of rizatriptan can include fatigue, somnolence, head and neck pressure, nonspecific dizziness, and nausea, and thus might have been expected to increase subjective units of discomfort despite its benefit for reduction of motion sickness.
Furthermore, absent rectoanal inhibitory reflex and high rectal neck pressure are encountered in anorectal aganglionosis [ 14].
The rectal neck pressure decreased to a mean of 74.6 ± 7.3 cm H2O (range 66 86) which matched with the normal pressures in our laboratory.
Edema of face and neck, pressure induced necrosis, hypotension or arrhythmia never reached such an extent that we had to end kinetic therapy.
The 6 constipated patients showed significantly high rectal neck pressure (p < 0.05), absent rectoanal inhibitory reflex and aganglionosis in the anorectal biopsy.
The mean rectal neck pressure in the 6 constipated patients was significantly higher than in the control subjects (p < 0.05, tables 2, 3), whereas the rectal pressure showed no significant difference (p > 0.05).
Considering the absence of the rectoanal inhibitory reflex and the presence of aganglionosis and high rectal neck pressure, we decided to perform anorectal myectomy for the 6 constipated patients, who gave an informed consent.
Patients reported significant improvements across all outcomes and impacts, with reductions in symptoms of 51.7% (heart racing), 33.9% (fatigue) 31.8% (heart flutters), 43.5% (dizziness), 38.6% (breathlessness), 44.2% (chest pressure), 33.1% (trouble concentrating), 15.9% (headache), 28.3% (neck pressure), and 23.4% (fainting) (P < 0.001).
