Influence of Oral Messages on the Activity of Wrist and Finger Flexor Muscles

NCT05206383 | Completed

Brief Summary

The aim of the study will be to evaluate the effect of oral messages on wrist and finger flexor muscle activity during the application of sham therapy in the form of paper plaster. For years, research has been conducted on the effects of dynamic plaster and rigid plaster on muscle function. In many cases, reports from different authors are contradictory. Therefore, the planned study will use placebo paper plaster with no proven therapeutic effect.

Outcome Measures

Primary Outcomes (1)

• Dynamometer tests

  Assessment of wrist and finger flexor muscle strength. Patient in sitting position with the elbow joint on the examined side bent and the forearm resting on the table. The patient squeezes the dynamometer for a period of 3-5 seconds.

  Change in measured parameters 10 minutes after application of the plaster and delivery of the oral message relative to baseline measurement.

Secondary Outcomes (1)

• Testing with Naroxon Ultimum EMG

  Change in measured parameters 10 minutes after application of the plaster and delivery of the oral message relative to baseline measurement.

Study Arms (3)

Positive message

EXPERIMENTAL

Group A - 30 subjects who will be told that positive message.

Behavioral: Positive message - placebo

Negative message

EXPERIMENTAL

Group B - 30 subjects who will be told negative message.

Behavioral: Negative message - nocebo

Neutral message

EXPERIMENTAL

Group C - 30 people who will be told neutral message.

Behavioral: Neutral message

Interventions

Positive message - placebo BEHAVIORAL

Subjects who will be told that "the applied plastering method significantly increases muscle strength" (positive message - placebo).

Positive message

Negative message - nocebo BEHAVIORAL

Subjects who will be told that "the applied plastering method has no effect on muscle strength" (negative message - nocebo).

Negative message

Neutral message BEHAVIORAL

Subjects who will be told that "the applied plastering method is currently under investigation and the investigators do not know its effects" (neutral message).

Neutral message
