NCT07499687

Brief Summary

This study will be conducted to evaluate the effect of the Traction, Pressure, and Rapid Muscle Release (TPR) technique, an innovative method used during intramuscular vitamin B12 (cyanocobalamin) injections, on patients' pain and satisfaction levels compared with the conventional injection method.

Outcome Measures

Primary Outcomes (3)

  • Patient Information Form

    The data collection form, developed by the researchers in line with the current literature, consists of questions regarding the patients' sociodemographic characteristics and anthropometric measurements. The form includes questions about patients' age, gender, marital status, educational level, employment status, history of chronic disease, regular medication use, and previous intramuscular (IM) injection experience, as well as three questions related to anthropometric measurements including height, weight, and body mass index (BMI).

    Immediately before the administration of the cyanocobalamin (vitamin B12) injection.

  • Visual Analogue Scale (VAS)-Pain

    First defined in 1921 and used to assess patients' subjective pain levels, the VAS is a form consisting of a horizontal line 10 cm long. The leftmost part of this measurement tool indicates "no pain," while the rightmost part indicates "unbearable pain." A high score on the scale indicates severe pain, while a low score indicates mild pain. The scale is scored as follows: 0 = no pain, 1-3 = mild pain, 4-6 = moderate pain, and 7-10 = severe pain.

    Immediately after the administration of the cyanocobalamin (vitamin B12) injection.

  • Visual Comparison Scale for Satisfaction

    In this scale, satisfaction levels are determined by scoring between 0 and 10. A score of "0" represents the lowest level of satisfaction, while a score of "10" represents the highest level of satisfaction. Patients are asked to indicate the level of their pain on a scale from 0 to 10, with the numerical value representing the patient's satisfaction level.

    Immediately after the administration of the cyanocobalamin (vitamin B12) injection.

Study Arms (2)

Intervention Group

EXPERIMENTAL

Patients who present to the hospital and are prescribed cyanocobalamin (vitamin B12) injections by a physician will be included in the study. In this group, injections will be administered using the Traction, Pressure, and Rapid Muscle Release (TPR) technique as part of routine clinical care and not for research purposes.

Other: TPR Injection Technique

Control group

NO INTERVENTION

Patients who present to the hospital and are prescribed cyanocobalamin (vitamin B12) injections by a physician will be included in the study. In this group, injections will be administered using the standard injection technique as part of routine clinical care and not for research purposes.

Interventions

To examine the effect of the Traction, Pressure, and Rapid Muscle Release (TPR) injection technique, a non-pharmacological method, on patients' pain and satisfaction levels during cyanocobalamin (vitamin B12) intramuscular injection.

Participants: Patients included in the study will be blinded to the injection technique used. Outcomes Assessor: All injections administered to patients in the experimental and control groups will be performed by a nurse who is a member of the research team. However, an independent nurse who is not involved in the research will be responsible for assessing the outcome measures obtained from the patients immediately after the procedure. This nurse will also be blinded to the study groups.
