An interventional study of Classical Back Massage and Passive Rest in Cognitive Performance in Healthy Adults, sponsored by DSW Ideis University. Not yet recruiting at 1 site in Poland. Open to participants aged 18 Years to 27 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-26.
Sponsored by DSW Ideis University · Not applicable, Interventional, and Basic science
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.
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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Other: Classical Back Massage · Behavioral: Passive Rest · Other: No Additional Break
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)
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.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Mean Heart Rate During TLoadDback
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.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Mean Skin Conductance During TLoadDback
Mean skin conductance in microsiemens during the task. Analyses will account for the precondition resting baseline from the same visit.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Perceived Workload (NASA-TLX)
Unweighted mean of six NASA-TLX ratings, each scored from 0 to 100 and oriented so that higher values indicate greater workload or poorer perceived performance.
Time frame: Immediately after the task at each of three visits approximately two weeks apart (about four weeks in total).
Median Response Time on TLoadDback
Median response time, in milliseconds, for correct responses that require a key press during the task.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Letter Accuracy on TLoadDback
Percentage of correct letter trials, including correct detections of repeated letters and correct withholding of responses to nonrepeated letters. Higher values indicate better performance.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Digit Accuracy on TLoadDback
Percentage of correctly classified digit-parity trials. Scores range from 0 to 100%, with higher values indicating better performance.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Incorrect Responses on TLoadDback
Number of incorrect responses during the task. Higher counts indicate more errors.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Omitted Required Responses on TLoadDback
Number of trials with no response when a response is required. Correct withholding of a response to a nonrepeated letter is not counted as an omission.
Time frame: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Plan to share: No — No individual participant data sharing plan has been established. Study results will be reported in aggregate.
