Key result
Low-frequency HRV and CPT-3 performance are linked to quality of life in traumatic brain injury.
Why the study?
Do physiological and neuropsychological functions impact quality of life in traumatic brain injury patients?
Observational
Do physiological and neuropsychological functions impact quality of life in traumatic brain injury patients?
Physiological and neuropsychological impairments, specifically CPT-3 performance and low-frequency HRV, significantly predict and mediate reduced quality of life in TBI patients.
CPT-3 and low-frequency HRV may mediate quality-of-life reductions in TBI; leaves open causal effects and intervention targets.
-test, Chi-square, repeated measure ANOVA, Pearson correlation, and mediation analysis. TBI group showed lower scores in memory, attention, executive function, and psychosocial measures. HRV results revealed lower baseline LF and task-related interaction effects in LF, LF/HF, and RMSSD. Mediation analysis further showed that CPT-3 performance and LF mediated the group's impact on self-reported quality of life. TBI patients exhibit physiological, neuropsychological, and psychosocial impairments, which are closely related to their QoL. In particular, the preservation response in the CPT-3 and LF showed significant predictive effects on QoL.

Chang et al. (2025) conducted an observational in Traumatic brain injury. Traumatic brain injury vs. Control group was evaluated on Quality of life. Traumatic brain injury patients exhibit physiological and neuropsychological impairments, with CPT-3 performance and low-frequency heart rate variability significantly mediating their quality of life.
