Psychogenic hand spasms, often linked to depression, present in distinct types. Diagnosis requires excluding other causes, and surgery is not recommended, with spontaneous recovery being rare.

Area of Science:

  • Neurology
  • Psychiatry
  • Hand Surgery

Background:

  • Psychogenic hand spasms are rare conditions.
  • They can manifest with varied clinical presentations.

Purpose of the Study:

  • To report on a series of patients with psychogenic hand spasms.
  • To characterize different types of psychogenic hand spasms.
  • To discuss diagnostic and treatment approaches.

Main Methods:

  • Retrospective case series of twelve patients over 8 years.
  • Clinical presentation, psychiatric diagnosis (DSM-III-R), and diagnostic workup were reviewed.
  • Electromyographic studies were used to exclude other etiologies.

Main Results:

Related Experiment Videos

  • Two types of psychogenic hand spasms were identified: Type I (elderly, medial finger flexion) and Type II (various attitudes post-trauma).
  • Common psychiatric diagnoses included major recurrent depression and personality disorders.
  • Surgical treatment was ineffective; spontaneous recovery was uncommon.

    • Conclusions:

    • Psychogenic hand spasm is a diagnosis of exclusion requiring a multidisciplinary team.
    • Surgical intervention is contraindicated.
    • Psychiatric comorbidities significantly influence the condition.
