Back Massage Before a Cognitive Task in Healthy Young Adults

9. november 2026 opdateret af: DSW Ideis University

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.

Detaljeret beskrivelse

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.

Foranstaltningsbeskrivelse
Tidsramme
Weighted Accuracy on TLoadDback (WAcc)
Tidsramme: 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.

During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Mean Heart Rate During TLoadDback
Tidsramme: 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.

During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Mean Skin Conductance During TLoadDback
Tidsramme: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

Mean skin conductance in microsiemens during the task. Analyses will account for the precondition resting baseline from the same visit.

Median Response Time on TLoadDback
Tidsramme: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
