Under-mattress ballistographic technology offers objective, passive measurement of key sleep continuity metrics—sleep onset latency, wake after sleep onset, and sleep efficiency—that are critical for optimizing Cognitive Behavior Therapy for Insomnia (CBT-I). This technology overcomes limitations of polysomnography, actigraphy, and consumer wearables, potentially improving treatment adherence and outcomes.
Background
Insomnia is the most common sleep disorder worldwide, with CBT-I as the first-line treatment. Current assessment relies heavily on subjective sleep diaries, which can be biased and burdensome. Polysomnography is resource-intensive and unsuitable for long-term home monitoring, while actigraphy lacks specificity in detecting wakefulness during rest. Consumer wearables often fail to measure treatment-relevant parameters accurately, limiting their clinical utility in CBT-I.

Key Findings
Under-mattress ballistography provides continuous, contactless monitoring of bed presence and sleep–wake transitions.
It accurately estimates key CBT-I metrics: time in bed (TIB), sleep onset latency (SOL), wake after sleep onset (WASO), and sleep efficiency (SE).
Ballistography overcomes limitations of PSG and actigraphy by directly detecting bed presence and intention to sleep without user input.
Consumer wearables primarily measure total sleep time, which is the least responsive parameter to CBT-I, limiting their feedback value.
Ballistographic metrics align closely with behavioral targets of CBT-I, supporting improved clinical decision-making and patient adherence.
Further validation and pragmatic trials, especially in psychiatric populations, are needed to confirm clinical benefits.
Clinical Implications
Incorporating under-mattress ballistographic technology into CBT-I protocols can provide objective, treatment-relevant sleep metrics that enhance monitoring accuracy and reduce patient burden. This may improve therapeutic feedback, patient engagement, and ultimately treatment outcomes. Clinicians should consider this technology as a complementary tool alongside subjective sleep diaries.
Conclusion
Under-mattress ballistographic technology represents a promising advancement in sleep behavior medicine by delivering objective, clinically relevant sleep continuity metrics that can augment CBT-I delivery. Its integration may address current limitations of existing sleep assessment tools and improve insomnia treatment efficacy.
