Effects of Tai Chi and cognitive behavioral therapy for insomnia on improving sleep in older adults: Study protocol for a non-inferiority trial

This will be the first non-inferiority randomized controlled trial to compare the efficacy and long-term outcomes of Tai Chi versus CBT-I for treating insomnia in older adults. This study will be of clinical importance as it supports the use of Tai Chi as an alternative non-pharmacological approach for insomnia treatment and sustainable management.
