简要总结
Background: Alzheimer's disease (AD) is characterized by cognitive impairment and behavioral impairment, and increasing attention is paid in the gait of AD patients. The aim of this randomized controlled trial (RCT) is to explore the effect of acupuncture on the cognitive function, gait performance, and hemodynamic changes in the prefrontal cortices.
Methods: In this RCT, a total of 108 AD patients will be randomly assigned into acupuncture group or control group for 8 weeks. The primary outcome will be Three-dimensional gait analysis and cerebral hemodynamics using functional near-infrared spectroscopy (fNIRS). Secondary outcomes include Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Barthel Index (BI).
Discussion: This trial is expected to explore the effect of acupuncture on cognitive function, gait performance, and hemodynamic changes in the prefrontal cortices for AD patients.
详细描述
This study aims to assess the clinical effect of acupuncture on gait performance in AD patients and to examine the acupuncture effect on cerebral cortices by identifying hemodynamic changes that occur in the prefrontal cortices using the fNIRS technique.

研究组 & 干预措施
Control group
Cognitive rehabilitation therapy: The cognitive training system (JZ-RZ-1020, Extreme Medical Technology, Hangzhou, China) will be used to help develop personalized rehabilitation plans for one-on-one training based on the cognitive function of each patient. The trainings include memory, hand eye reinforcement, attention, reaction. Patients are treated for 30 minutes each time and 5 times a week for 8 weeks.
干预措施: Acupuncture (Procedure)
Acupuncture group
Acupoints: Baihui (GV20), Sishencong (EX-HN1), Fengchi (GB20), Taixi (KI3), Zusanli (ST36), Sanyinjiao (SP6), Neiguan (PC6), and Shenmen (HT7).

结局指标
主要结局
Three-dimensional gait analysis
时间窗: Assessments will be performed before the treatments, at 4 weeks after treatments, and at 8 weeks after treatments.
Vicon's Nexus system detects gait parameters and kinematic parameters, including step length, stride, pace, step width, step frequency, single/double stand phase, turning (time and number of steps required for turning), swing phase.
Cerebral hemodynamics
时间窗: Assessments will be performed before the treatments, at 4 weeks after treatments, and at 8 weeks after treatments.
A total of 22 channels are configured using 8 emitters and 8 detectors, with each light source emitting three wavelengths (780 nm, 805 nm, and 830 nm) of light, and the original intensity signal is recorded at a sampling frequency of 13.33Hz. Patients need to try to keep the head fixed during the walking.
次要结局
- Montreal Cognitive Assessment(Assessments will be performed before the treatments, at 4 weeks after treatments, and at 8 weeks after treatments.)
- Mini-Mental State Examination(Assessments will be performed before the treatments, at 4 weeks after treatments, and at 8 weeks after treatments.)
