NCT03443388

Brief Summary

This is a two-part study that aims to determine the reliability and safety of the use of the Hövding inflatable helmet in seizures, as evidenced by the deployment of the helmet during seizures, and qualitative patient reporting.

Outcome Measures

Primary Outcomes (2)

  • Part 1: Number of Successful Deployments

    3 out of 4 successful deployments was set as a criteria to allow advancement to part 2.

    1 day

  • Part 2: Helmet Deployment Questionnaire

    Differences in Helmet Deployment Questionnaire responses will be compared between subjects wearing helmets during a seizure, and subjects not wearing helmets during a seizure.

    6 months

Secondary Outcomes (4)

  • Rivermead Post Concussive Scale

    6 months

  • Seizure Questionnaire

    6 months

  • Injury-related Medical Record Review

    6 months

  • Helmet Deployment Questionnaire (Seizure/Not Seizure)

    6 months

Study Arms (2)

Part 2: Helmet

ACTIVE COMPARATOR

After a screening period, 10 patients with drug resistant epilepsy will first be assigned to wear one Hövding inflatable helmet in their daily lives. Subjects will fill out questionnaires about their seizures, injuries, and the circumstances of inflation when it occurs. After experiencing a seizure resulting in a fall or any helmet deployment, patients will crossover to the "no helmet" group. If no seizure resulting in fall occurs in 3 months, participation will end.

Device: Hövding inflatable helmet

Part 2: No Helmet

NO INTERVENTION

After a screening period, 10 subjects with drug resistant epilepsy will first be assigned to not wear an inflatable helmet. Subjects will fill out questionnaires about their seizures and injuries. After approximately 3 months, patients will crossover to the "helmet" group.

Interventions

The Hövding inflatable helmet is designed for cyclists as a collar with a deployable airbag that inflates when a sensor detects rapid changes in acceleration. The inflated helmet wraps the back and sides of the user's head in inflated nylon fabric which then slowly deflates after deploying.

Model Details: This is an open-label, randomized, 2-way crossover pilot safety study of the Hövding helmet device in patients with drug resistant epilepsy. Reference therapy is no head-protective device. Part 1 will test helmets on 4 normal controls falling from standing. If the helmet deploys in at least 3 out of 4 falls, we will proceed to Part 2. Part 2 will enroll up to 20 patients with Drug Resistant Epilepsy. Patients will be block randomized to first wear the helmet in their daily lives until helmet deployment or for up to 3 months, or to first not wear a helmet for up to 3 months. Patients in each group will complete self-administered questionnaires. We will compare circumstances, injuries, and post concussive scales in seizures resulting in falls occurring while the helmet was worn versus seizures resulting in falls occurring while the helmet was not being worn using daily seizure calendar, medical records review, the Rivermead Post Concussive Scale and other qualitative questionnaires.
