What this trial studies

This study evaluates the effectiveness of Heart Rate Variability (HRV) biofeedback training in patients diagnosed with psychogenic cervical dystonia, who are not candidates for surgery. Over a six-month period, participants will undergo 12 sessions of HRV biofeedback aimed at enhancing their self-regulatory skills and reducing symptoms such as abnormal head posture and pain. The intervention is designed to address the psychological aspects of their condition, potentially improving anxiety, depression, and overall quality of life.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 75 who exhibit symptoms of psychogenic cervical dystonia and have been diagnosed with a somatoform disorder.

Not a fit: Patients with organic causes for their cervical dystonia or those who do not meet the criteria for psychogenic disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a non-invasive and non-pharmacological treatment option for patients suffering from psychogenic disorders.

How similar studies have performed: While HRV biofeedback is a relatively novel approach in this specific context, similar interventions have shown promise in managing other psychogenic and functional disorders.

Inclusion criteria:

* Age 18 to 75
* Responding to somatoform disorder characteristics as described in ICD-10 (F45: "The onset of physical symptoms associated with an insistent medical quest, persisting despite repeated negative assessments and statements by physicians that the symptoms have no organic basis. If there is a genuine physical disorder, it does not account for the nature or severity of the symptoms, or the distress or concerns of the subject. The multidisciplinary team will determine whether or not the diagnosis of conversion disorder (disorder with functional neurological symptoms) of the DSMV (300.11) \[ICD-10 equivalent: F44.4 "dissociative disorder with abnormal movements"\] is associated with the diagnosis of conversion disorder (disorder with functional neurological symptoms) of the DSMV (300.11) \[ICD-10 equivalent: F44.4 "dissociative disorder with abnormal movements"\], selected by the multidisciplinary team after a phase 1 assessment.
