“…The finding of anxiety in musicians with focal dystonia harmonizes with other reports of anxiety in patients with various forms of focal dystonia,7, 8, 13, 14 although findings in the literature are not unambiguous 9, 14. It has been suggested that reduced cortical inhibition may play a role in focal dystonia as well as in anxiety.…”

“…Previous studies have focused on psychological conditions in patients with other forms of dystonia. Depressive, anancastic, sensitive, and hysterical traits were observed in patients with writer's cramp,6 there have been contradicting reports about anxiety in patients with writer's cramp: anxiety was occasionally observed in patients with writer's cramp by Gibson7 and Cottraux and colleagues,8 whereas no higher levels of anxiety were seen in such patients compared to normal controls by Harrington and coworkers 9. Obsessive compulsive disorder has been reported in association with idiopathic focal dystonia10 as well as with myoclonus dystonia 11.…”

Anxiety in musicians with focal dystonia and those with chronic pain

Psychological conditions were studied in 20 musicians with focal dystonia and compared with 20 musicians with chronic pain and 30 healthy musicians using the Freiburg Personality Inventory and the Questionnaire for Competence and Control Orientations. Additional questionnaires focused on perfectionism and anxiety particularly with regard to the dynamics of these psychological features. Musicians with focal dystonia and those with chronic pain more often displayed anxiety than controls. In both patient groups, anxiety was present before onset of the playing-related disorder. Dystonic musicians additionally showed higher levels of perfectionism than controls, which was not observed in musicians with chronic pain.

“…That is non consistent to our study. In this present study maximum writer's cramp was associated with great deal of writing person like teacher, student, clerk which is consistent with Harrington's study 6 . In this present study there was no significant perfusion difference of basal ganglia between writer's cramp and non-writer's cramp group in the left side (P=0.851) during writing and also in the right side (P=0.671).…”

Background: Writer’s cramp is probably related to abnormal functioning of basal ganglia. But the actual mechanism is not known.Objective: The purpose of the present study was to evaluate the functional association of writer’s cramp with basal ganglia through SPECT study.Methodology: This prospective case control study was carried out in the Department of Neurology, Bangabandhu Sheikh Mujib Medical University, Dhaka and institute of nuclear medicine (INM), Dhaka from July 2001 to June 2003 to understand the basic pathophysiology of writer’s cramp by SPECT study and to compare the perfusion difference of basal ganglia between writer’s cramp and non-writer’s cramp group. A total of 20 respondents consisting of 10 in each group of writer’s cramp and non-writer’s cramp group as cases and controls respectively were enlisted by simple random method. Both the group of respondents underwent Tc99m HMPAO SPECT study during rest and writing period.Result: Out of 10 cases male patients were nine (90%) and female patient was one (10%) with male female ratio 9:1. Majority of patients presented third to fifth decades of which maximum (30%) were from 30-34 age group. Total six (60%) patients had simple writer’s cramp next three (30%) progressive writer’s cramp and one with dystonic variety. Maximum writer’s cramp patients were associated with great deal of writing (teacher, student, clerk, banker) and or performed repetitive hand movement (computer operator) from the point of occupational distribution. The perfusion difference of basal ganglia of both writer’s cramp and non-writer’s cramp group was seen by Tc99m HMPAO SPECT study during rest and writing period. First visual analysis of the scans by an expert nuclear medicine specialist showed no difference and then quantification of perfusion difference of basal ganglia by using SIEMENS macro programming environment (MPE) software showed no significant perfusion difference of basal ganglia between case and control group both during rest and writing period. In addition it was found highly significant perfusion difference (P=0.000321) separately in controls between left side and right side comparison during rest and significant difference (P=0.03) in writing and also significant in right side (P=0.022) during comparison of rest and writing period. The study also showed a significant perfusion difference (P=0.01) in cases between left and right comparison during writing and also significant perfusion difference (P=0.018) was found in rest and writing comparison of left side in writer’s cramp patients.Conclusion: There is no abnormality in basal ganglia perfusion pattern among the writer’s cramp patient.Journal of National Institute of Neurosciences Bangladesh, 2018;4(2): 92-96

“…It is also unlikely that focal hand dystonia is due to an anxiety or neurotic disorder (9). We found no relationship between the medical history, personality scale scores, or patient test behavior and any of the characteristics of focal hand dystonia or motor performance as measured by finger dexterity or reaction times.…”

Is focal hand dystonia associated with psychopathology?

The purpose of this study was to determine if patients with focal hand dystonia have any significant psychopathology. We studied 20 patients with hand cramps who were participating in a therapeutic trial of botulinum toxin injections. Patients were interviewed and administered the Minnesota Multiphasic Personality Inventory (MMPI). Beck Depression Inventory, Spielberger State-Trait Anxiety Scale, a finger tapping test, and a choice serial reaction time test. Behavioral ratings were also obtained. Group statistics indicated that all personality scale scores and performances on motor tasks were within normal limits. Four out of 20 patients demonstrated mild depression. Trait anxiety scores were higher than state anxiety scores, suggesting that receiving medical treatment had a beneficial effect on mood. The number of depressive symptoms endorsed on the MMPI was correlated with reaction time speed but not finger dexterity. None of the 20 patients reported a remarkable psychiatric history. These results indicate that hand cramps are not associated with serious psychopathology.
