| Other comments |
Questionnaire determined that cataplexy was best differentiated from other types of muscle weakness when triggered by only three typical situations: "when hearing and telling a joke," "while laughing," or "when angry." Face or neck, rather than limbs, were also more specifically involved in clear-cut cataplexy. |
| Patient populations in who questionnaire has been validated | Patients referred to a Sleep Disorder Clinic |
