Back Massage Before a Cognitive Task in Healthy Young Adults

9 de novembro de 2026 atualizado por: 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.

Descrição detalhada

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.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Weighted Accuracy on TLoadDback (WAcc)
Prazo: 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
Prazo: 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
Prazo: 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.

During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Perceived Workload (NASA-TLX)
Prazo: Immediately after the task at each of three visits approximately two weeks apart (about four weeks in total).

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.

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

Median response time, in milliseconds, for correct responses that require a key press during the task.

During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

Outras medidas de resultado

Medida de resultado
Descrição da medida
Prazo
Letter Accuracy on TLoadDback
Prazo: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

Percentage of correct letter trials, including correct detections of repeated letters and correct withholding of responses to nonrepeated letters. Higher values indicate better performance.

During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Digit Accuracy on TLoadDback
Prazo: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

Percentage of correctly classified digit-parity trials. Scores range from 0 to 100%, with higher values indicating better performance.

During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).
Incorrect Responses on TLoadDback
Prazo: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

Number of incorrect responses during the task. Higher counts indicate more errors.

During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

Prazo: During the 16-minute task at each of three visits approximately two weeks apart (about four weeks in total).

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.
