Back Massage Before a Cognitive Task in Healthy Young Adults
Classical Massage as Preparation for a Cognitive Task: A Randomized Three-Condition Crossover Study
This study will compare a 15-minute back massage, 15 minutes of quiet rest, and no additional break before a mental task in healthy adults aged 18 to 27 years. Each participant will complete all three conditions in a random order at separate visits. The study will measure task accuracy, heart rate, skin conductance, and perceived workload to assess whether massage offers a benefit beyond rest.
研究概览
详细说明
This randomized crossover study includes three visits approximately two weeks apart. Task practice and individual calibration take place before a seated resting measurement. Participants then receive massage, rest lying face down, or proceed directly to the task. The TLoadDback task lasts 16 minutes at a fixed, individually calibrated pace. Physiological signals are recorded during rest and task performance. Participants complete the NASA-TLX questionnaire after the task.

干预/治疗 |
|---|---|
|
实验性的：Sequence ABC
Back massage, passive rest, then no additional break; one condition per visit before TLoadDback. |
A 15-minute classical back massage while lying face down, delivered by trained personnel before TLoadDback. A 15-minute quiet rest lying face down on the massage table without massage before TLoadDback. TLoadDback begins immediately after the seated resting baseline, without an additional 15-minute preparation period. |

Weighted Accuracy on TLoadDback (WAcc)
大体时间：During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
|
Weighted accuracy across the full task: 0.65 x letter accuracy + 0.35 x digit accuracy. Letter accuracy includes correct detections and correct withholding of responses; digit accuracy is correct parity classification. Scores range from 0 to 100%, with higher scores indicating better performance. |

Mean Heart Rate During TLoadDback
大体时间：During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
|
Mean heart rate in beats per minute during the task, derived from photoplethysmography. Analyses will account for the precondition resting baseline from the same visit. |
