trihexyphenidyl and Dystonia

trihexyphenidyl has been researched along with Dystonia in 71 studies

Trihexyphenidyl: One of the centrally acting MUSCARINIC ANTAGONISTS used for treatment of PARKINSONIAN DISORDERS and drug-induced extrapyramidal movement disorders and as an antispasmodic.

Dystonia: An attitude or posture due to the co-contraction of agonists and antagonist muscles in one region of the body. It most often affects the large axial muscles of the trunk and limb girdles. Conditions which feature persistent or recurrent episodes of dystonia as a primary manifestation of disease are referred to as DYSTONIC DISORDERS. (Adams et al., Principles of Neurology, 6th ed, p77)

Trial Outcomes

Craniocervical Dystonia Questionnaire

The Craniocervical Dystonia Questionnaire (CDQ-24) is a patient-rated health related quality of life (HR-QoL) measure for craniocervical dystonia. It is composed of 24 items, forming 5 subscales: stigma, emotional well-being, pain, activities of daily living, and social/ family life. Items are rated on a 5-point scale. Each item consists of five statements representing increasing severity of impairment, scored from 0 to 4. Subjects will be instructed to indicate how they have felt during the past two weeks because of dystonia by selecting one of the five statements for each item. The total score reported here can range from 0-96, with a higher score indicating a greater impact of dystonia on quality of life. (NCT02542839)

Dystonia Severity as Assessed by the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS)

A clinical assessment of dystonia severity will be conducted at each study visit using the TWSTRS. The TWSTRS is a widely accepted composite rating scale for PCD with subscales for clinical severity, functional disability, and associated pain. The total score reported here can range 0-85, where a higher scores represent greater dystonia severity. (NCT02542839)

TMS Measure Referred to as Cerebellar Inhibition (CBI)

A measure of the cerebellar-brain inhibition(CBI) will be conducted using a TMS device determining the ability of the coil to activate the cerebellum. CBI is calculated by taking the mean of amplitudes of motor-evoked potentials (mV) in response to conditioned stimulation and dividing it by the mean of amplitudes of motor-evoked potentials (mV) in response to unconditioned stimulation (i.e., the control condition). Thus it is a measure of the degree of inhibition due to a conditioning stimulus, where <1 indicates inhibition, =1 indicates no inhibition, and >1 indicates not inhibition but excitation. As a ratio of amplitudes, it does not have units. (NCT02542839)
