Summary
The BiteStrip device effectively screens for masseter electromyographic events indicating sleep bruxism (SB), showing strong correlations with traditional methods. This electronic device is a viable tool for SB identification.
Area of Science:
- Neurology
- Sleep Medicine
- Biomedical Engineering
Background:
- Sleep bruxism (SB) is a common sleep-related movement disorder.
- Accurate screening for SB is crucial for timely diagnosis and treatment.
- Traditional polysomnography with masseter electromyography (MEMG) is effective but resource-intensive.
Purpose of the Study:
- To validate a novel, portable electronic device, the BiteStrip, for screening sleep bruxism.
- To compare the diagnostic performance of BiteStrip against standard MEMG during polysomnography.
Main Methods:
- Overnight polysomnography was conducted on 18 participants (6 SB patients, 4 OSA patients, 8 controls).
- Simultaneous MEMG and BiteStrip recordings were obtained.
- Data analysis included accuracy measures, correlation analyses (Spearman's rho), and Bland-Altman plots.
Main Results:
- BiteStrip demonstrated acceptable average sensitivity (0.72) and positive predictive value (0.75).
- Strong correlations were found between BiteStrip and MEMG scores (r = 0.79-0.81).
- Bland-Altman analysis indicated good agreement between the two measurement methods.
Conclusions:
- The BiteStrip device shows a strong relationship with MEMG in identifying masseter electromyographic events related to sleep bruxism.
- The BiteStrip is a viable and potentially more accessible screening tool for sleep bruxism.
