2026年11月9日 更新者：Cindy Kin、Stanford University

Prehab-COG: Does Preoperative Exercise Improve Postoperative Cognitive Outcomes? A Pilot Study.

The purpose of this protocol is to evaluate the feasibility and acceptability of a preoperative exercise intervention (Prehabilitation) program, along with intraoperative Electroencephalography (EEG) recordings, and pre and post operative cognitive testing in older patients undergoing a major surgery.

  3. Plan to be admitted to the hospital after surgery for a minimum of one night.
  4. ASA physical status classification I to III.
  5. English or Spanish fluency (Cognitive testing only validated to be used with English or Spanish speakers).

Exclusion Criteria:

  2. Failure to satisfy adequate hearing test with/without hearing aids.
  3. Visual impairment.
  4. Unplanned ICU admission after surgery.
  5. Patients who are undergoing another intervention study that consists of a cognitive or exercise intervention.
  6. Inability to provide consistent EEG data of sufficient quality, determined at enrollment.
  7. Subjects with medical conditions including but not limited to: Angina pectoris, Congestive Heart Failure (CHF) that make it dangerous for unsupervised physical activity, cognitive and psychiatric conditions that may affect ability to consent.

武器和干预

参与者组/臂
干预/治疗
实验性的：Moderate Exercise Arm

The participants will undergo the virtual exercise intervention 2xweek for 3-4 weeks prior to surgery, and take cognitive testing with non-invasive EEG recordings at 5-point time (the baseline prior to start of the exercise program, at 2-4 days prior to surgery, during the surgery, post-op, and 30-day post surgery). Participants will also be interviewed after the intervention and after surgery to obtain their feedback on their experience with the study procedures.
行为的：Tailored exercise program

Eligible participants will receive their exercise program, relevant informational material and training. The exercise program will be tailored to the physical fitness of the participants. The 2xweek virtual sessions take 30 minutes each and include guided exercises at mild-moderate intensity.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Evaluate the feasibility of a preoperative home-based exercise intervention program, with intraoperative EEG recording, and pre and post operative cognitive testing, among older patients undergoing major surgery.
大体时间：Maximum 3 months from participant enrollment to end/completion of all study-related tasks.

Feasibility will be measured by:

  1. Proportion of Eligible Patients Approached Who Enrolled (Number of eligible patients who enrolled divided by the number of eligible patients approached)
  2. Proportion of Enrolled Participants Completing All Planned Study Data-Collection Assessments (Number and the percentage of the completion for each of the planned data collection points)
Maximum 3 months from participant enrollment to end/completion of all study-related tasks.
Evaluate the acceptability of a preoperative home-based exercise intervention program, with intraoperative EEG recording, and pre and post operative cognitive testing, among older patients undergoing major surgery.
大体时间：Maximum 3 months from participant enrollment to end/completion of all study-related tasks.

Acceptability will be measured by:

1) Aggregated (mean) Score of Surveyed Participants' Rating Across Each Study-Task (Average score of participants' ratings across study tasks, including exercise program, EEG recording and cognitive testing).
Maximum 3 months from participant enrollment to end/completion of all study-related tasks.
