Multiple Sleep Latency Test (MSLT)
A MSLT is always performed the day after an overnight sleep study. The purpose of this study is to assess the sleepiness of your child after an overnight study in which the quality of sleep has been monitored. Your child will be awakened by 6:30 a.m. so that the first nap can begin between 8:30 a.m. and 9 a.m.
The electrodes that were placed on your child for the overnight study will remain but some adjustment or reapplication may be necessary in the morning. The MSLT study is run at different intervals during the day, approximately every two hours from the first "nap." You and your child should plan on being in the Sleep Center until approximately 5 p.m.
Your child should wear loose, comfortable clothing that allows the pant leg to be raised. Between nap times, you should have activities available, such as homework, reading materials or music to keep your child from getting bored. Your child will not be allowed to sleep between naps.
Two meal vouchers, each valued at $5, will be provided for your child during his or her stay in the Sleep Center. These vouchers are only redeemable in the Hospital cafeteria.
