In this study, we aim to investigate the impact of professional touch techniques on treatment expectations and adherence in German-speaking adults with current back or neck pain. Participants will engage in a 45-minute interaction, including structured components and physical touch interventions. We will assess treatment expectations, treatment effects, adherence, and participant motivation. Our study will provide insights into the role of touch in healthcare interactions and its influence on treatment outcomes.
Research findings indicate that the interaction between healthcare professionals and patients can significantly influence both treatment expectations and their effectiveness. A compassionate, caring, and attentive doctor-patient interaction plays a crucial role in patient satisfaction and promotes accelerated recovery. Moreover, patient expectations are not solely shaped by interactions with healthcare providers but are also conceptualized through conditioning processes as one of the key mechanisms of the placebo effect. The effective performance of medical staff can further intensify patient expectations, contributing to an increased placebo response. While the effects of verbal communication on the placebo effect have been extensively studied, there is less research on the impact of nonverbal factors such as touch. Touch is a fundamental aspect of social interaction that can positively affect well-being and health. Touch is regarded as a mechanism for the positive health effects of social relationships and plays a significant role in bonding, communication, and reward. Physical touch can provide patients with a sense of presence and grounding, helping them feel seen, reassured, relaxed, and validated. In medical treatment, touch can enhance a sense of being taken seriously and cared for, thereby alleviating suffering and improving well-being. However, the full range of communicative potential in professional touch remains largely untapped, while a well-founded interdisciplinary synthesis is still lacking. For the planned study, we aim to recruit German-speaking adult participants who report current back or neck pain. Recruitment will be carried out through targeted outreach via various channels such as mailing lists, internet forums, and flyers. In an online experiment, we will initially assess baseline treatment expectations and current pain intensity. Subsequently, participants will be randomized into two experimental conditions. Participants will engage in a 45-minute interaction, comprising a structured opening, a brief interview, a standardized diagnostic examination, a detailed explanation of the pain relief cream, specific exercises, and a final farewell. Within the two experimental groups, physical interaction, specifically the application of professional touch techniques, in the form of procedural touch (serving diagnostic or therapeutic purposes), will be manipulated by aspiring pain specialists to examine its influence on various treatment parameters such as treatment expectations, treatment effects, treatment adherence, and participant motivation. Additionally, perceived empathy as well as warmth and competence of the treating person will be analyzed as relevant factors. Following the interaction, participants will be asked to perform specific exercises daily for one week and apply a placebo cream. Adherence to these medical and behavioral measures is a critical outcome criterion. At the end of the study, a systematic assessment of relevant behavioral parameters will be conducted to quantify potential changes in participants' behavior related to the interventions performed.

| Touch Intervention | Behavioral | The participants will be examined, with various areas in the neck and upper back being palpated. Subsequently, the exercises to be performed at home will be demonstrated by the experimenter. The experimenter will ensure correct execution by touching specific areas in the neck and upper back of the participants. Finally, the participants will be provided with a cream to be applied to the affected regions. Placebo cream: The participants receive an inert placebo cream, which is a standard basic cream infused with lemon oil, produced by a local pharmacy. Participants are informed that they are about to receive an effective analgesic cream. Placebo exercises: Participants are assigned a series of five core exercises, with an optional supplementary exercise available in case any of the core exercises proves ineffective for the participants. Participants are led to believe that these exercises are expected to have therapeutic effects. |

| Warmth and competence ratings of the practioner | Participant perceptions of warmth and competence of the practitioner are measured via the Warmth and Credibility Screener - German translation: 12 items assessing perceived warmth (6 items) and competence (6 items) on a 5-point Likert scale ranging from 1 (not at all) to 5 (completely) with high scores indicating greater ratings of warmth and competence (Seewald & Rief, submitted for publication; English original by Fiske et al., 2002.) | After the intervention (45 minutes after baseline) |
| Treatment adherence (Exercise Adherence Rating Scale (EARS)) | The Exercise Adherence Rating Scale (EARS) is a self-administrated questionnaire designed to measure adherence to prescribed home-based exercises. The EARS consists of six items that measure adherence and 10 items related to reasons for nonadherence. The items were scored using a 5-point Likert scale ranging from 0 = completely agree to 4 = completely disagree with a possible summed score range from 0 to 64. Positively phrased items were reversed scored so that a higher overall adherence score indicated better adherence to exercise. | Post-treatment (1-week after baseline) |
| Adherence (Behavioral Measure) | Self-report on the number of days participants have fully completed the prescribed exercises and properly applied the cream. | Post-treatment (1-week after baseline) |
| After the intervention (45 minutes after baseline) |
| Attitude towards social touch (Social Touch Questionnaire (STQ)) | The STQ assessed the individual attitude towards touch. It comprises 20 items that are to be answered on a 5-point Likert-scale from 0 (not at all) to 4 (extremely). | Baseline |
| Anxiety (State-Trait Anxiety Inventory (STAI)) | The Spielberger State-Trait Anxiety Inventory (STAI) is a 40-item self-administered questionnaire designed to assess both immediate state anxiety (reflecting current feelings at the moment) and long-term trait anxiety (reflecting general anxiety tendencies) with 20 items each. Participants rate their responses on a 4-point Likert scale, ranging from 1 (indicating "not at all" for state anxiety or "almost never" for trait anxiety) to 4 (indicating "very much so" for state anxiety or "almost always" for trait anxiety. According to the developer (Spielberger, 1983), scores of 20-39, 40-59, and 60-80 indicate low, moderate, and high anxiety, respectively. | Baseline |
| Problems and Obstacles During the Intervention | Problems with the execution of daily exercises were recorded in the online survey using an open response format. | Post-treatment (1-week after baseline) |
| Experiences with Physiotherapy | The experience with physiotherapy is recorded on a 10-point scale from 0=never to 10=very frequent. High values represent a lot of experience with physiotherapy. | Post-treatment (1-week after baseline) |
| Parallel Treatments | Treatments that were received during the participation period are selected in the survey (e.g., primary care treatment, orthopedic treatment). If a treatment is not listed, there is an option to specify it in an open field. | Post-treatment (1-week after baseline) |
