Hello Btxbtx,
Sorry for the late response. When treating Plantar Fasciitis, you should avoid stretching the plantar muscle, which night splints generally do. Our recommendation would be for 3-5 BFST treatments daily, trying to focus them before activity or work, and making sure you do one treatment before bedtime and once when you wake up.
A twenty minute treatment will allow for 4+ hours of stimulated blood flow, allowing the healing process to continue into your sleep. After a few treatments you will feel a noticeable difference upon wake up each day.
