Objective

2

Based on psychomotor vigilance task (PVT) and heart rate var

iability (HRV)

to explore the effect of

Anshen Yizhi

(calm the spirit and enhance mental faculties) acupuncture on attention and autonomic nervous function after acute sleep deprivation (ASD).

Methods

2

Thirty healthy participants with regular sleep patterns were included in the study.

Anshen Yizhi

acupuncture was applied to the participants before and after ASD. Acupuncture was given at bilateral Shenmen (HT7) and Taixi (KI3)

after obtaining

qi

perform reinforcing-technique twirling was performed for 1 min

then retain the needles for 10 min. The HRV indexes of standard deviation of NN intervals (SDNN)

the root mean square of the difference between two adjacent R-R intervals (RMSSD)

the proportion of adjacent heartbeat interval difference exceeding 50 ms (pNN50%)

the frequency domain indexes of high frequency (HF)

low frequency (LF) and low frequency high frequency ratio (LF/HF)

PVT test reaction time (RT) and coefficient of variation (CV) were compared before and after acupuncture.

Results

2

Compared before acupuncture in participants before ASD

LF and HF increased after acupuncture in participants before ASD (

P

<

0.01); HR

RMSSD

HF and LF decreased (

P

<

0.01

P

<

0.05)

RT and CV increased (

P

<

0.01) before acupuncture in participants after ASD. Compared with before acupuncture in participants after ASD

SDNN

RMSSD

pNN50%

HF and LF increased (

P

<

0.01) and RT decreased (

P

<

0.05) after acupuncture in participants after ASD.

Conclusion

2

Anshen Yizhi

acupuncture can improve attention impairment after ASD

possibly related to the regulation of autonomic nervous function.
