| Infant colic is characterized by excessive and inconsolable crying, hypertonicity, and wakefulness, mainly in the evening. |
| In conditions of volume depletion or hypertonicity, secretion of antidiuretic hormone is stimulated, water is reabsorbed, and a concentrated urine is excreted. |
| Perineal biofeedback may be particularly effective when there is presumed hypertonicity of the pelvic floor muscles. |
| The hypertonicity of the radiopaque agent draws fluid into the bowel to facilitate passage and expulsion of the tenacious meconium. |
| This vicious cycle forces the fissure open and prevents healing, which in turn exacerbates the sphincter hypertonicity. |
| The hypothesis of the study was that acupuncture would reduce muscle hypertonicity in children with cerebral palsy. |
