Influence of Oral Messages on the Activity of Wrist and Finger Flexor Muscles
Influence of Oral Messages on the Activity of Wrist and Finger Flexor Muscles - in the Context of Application of Sham Therapy
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.

Descrizione dettagliata
People's words can have a huge impact on how we interpret our surroundings, what we expect and experience, and how we behave. The placebo (and nocebo) effects are a clear example here. The way health professionals discuss, describe and inform patients about the characteristic effects of a given disease, its prevention, diagnosis and treatment influences patients' feelings and expectations, which in turn affects their psychobiological responses, subjective feelings and treatment outcomes.
The right choice of words by clinicians influences patients' response to medical treatments and procedures, both active and sham. The way in which information about the effects of treatment is communicated to patients can reinforce the outcomes of a particular treatment (placebo) or reverse clinically-proven effects of an active treatment, or even increase its adverse effects. The right messages can reduce the nocebo effect. And vice versa, the wrong choice of information provided may increase the patient's anxiety and disease symptoms.
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.
Main hypothesis:
The use of a positive message will have an effect on increasing the activation and strength of the flexor muscles of the wrist joint and fingers.
Research questions:
- Does a positive message have an effect on increasing the activation and strength of the flexor muscles of the wrist joint and fingers?
- Does a negative message have an effect on increasing the activation and strength of the flexor muscles of the wrist joint and fingers? Does a neutral message have an effect on increasing the activation and strength of the flexor muscles of the wrist joint and fingers?
The study will be a prospective, flow-up study using a differential variable in the form of the type of message used (positive - placebo, negative - nocebo, neutral). The respondents will be randomly allocated to study groups using sealed allocation sheets.
Before taking part in the study, each subject will be familiarised with the course of the study and must give written informed consent to participate in the study and to be randomly assigned to a specific study group.
The subjects will be assessed twice - before applying a paper plaster and 10 minutes after applying the plaster and delivering a voice message.

Intervento / Trattamento |
|---|---|
|
Sperimentale: Positive message
Group A - 30 subjects who will be told that positive message.
|
Subjects who will be told that "the applied plastering method significantly increases muscle strength" (positive message - placebo).
|
|
Sperimentale: Negative message
Group B - 30 subjects who will be told negative message.
|
Subjects who will be told that "the applied plastering method has no effect on muscle strength" (negative message - nocebo).
|
|
Sperimentale: Neutral message
Group C - 30 people who will be told neutral message.
|
Subjects who will be told that "the applied plastering method is currently under investigation and the investigators do not know its effects" (neutral message).

Assessment of wrist and finger flexor muscle activity. Patient in sitting position with the elbow joint on the examined side bent and the forearm resting on the table. The subject's arm is adducted, the wrist joint in an intermediate position. The electrodes are glued in the belly area of the flexor muscles of the wrist and fingers - about 2 cm from the medial epicondyle of the humerus in a distal direction at a distance of 1 cm from each other. 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.
