Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Potential new demographic indicators of cervical dystonia | Analysis of demographic factors will be performed to identify additional environmental factors that are more prevalent in the CD patient population than in healthy controls and unaffected family members. Through exploration of potential new indicators, the investigators hope to progress the long-term goal of improving the rate of cervical dystonia diagnosis. | Up to 6 months after consent is obtained | |
Other | Potential new medical indicators of cervical dystonia | Analysis of medical history and specific elements of the neurological examination will be performed to identify additional symptoms and environmental factors that are more prevalent in the CD patient population than in healthy controls and unaffected family members. Emphasis will be placed on sensory tricks, as previous studies and clinical experience have shown that patients often use sensory tricks such as touching the face, hand, or neck to temporarily relieve muscle contraction. Through exploration of potential new indicators, the investigators hope to progress the long-term goal of improving the rate of cervical dystonia diagnosis. | Up to 6 months after consent is obtained | |
Primary | Prevalence of spatial discrimination threshold in cervical dystonia patients, unaffected family members, and healthy volunteers | For participants in all groups, the investigators will examine the prevalence of spatial discrimination threshold. Prevalence of spatial discrimination threshold will be determined with a task using Johnson-Van-Boven-Phillips (JVP) domes. The spatial discrimination threshold will be recorded as the mean of both hands at the 75% level of accuracy. The research coordinator will report prevalence of spatial discrimination threshold as a descriptive statistic. | Up to 6 months after consent is obtained | |
Primary | Prevalence of temporal discrimination threshold in cervical dystonia patients, unaffected family members, and healthy volunteers | For participants in all groups, the investigators will examine the prevalence of temporal discrimination threshold. Prevalence of temporal discrimination threshold will be determined with a visual-visual discrimination task.The research coordinator will report prevalence of temporal discrimination threshold as a descriptive statistic. | Up to 6 months after consent is obtained | |
Primary | Prevalence of vibration-induced illusion of movement in cervical dystonia patients, unaffected family members, and healthy volunteers | For participants in all groups, the investigators will examine the prevalence of vibration-induced illusion of movement. Prevalence of vibration-induced illusion of movement will be determined by recording the change in displacement of the tracking arm during a vibration-induced illusion of movement task. The research coordinator will report prevalence of vibration-induced illusion of movement as a descriptive statistic. | Up to 6 months after consent is obtained | |
Primary | Prevalence of impaired kinesthesia in cervical dystonia | For participants in all groups, the investigators will examine the prevalence of impaired kinesthesia. Kinesthesia will be determined by a neurologist during the neurological examination. The research coordinator will report prevalence of impaired kinesthesia as a descriptive statistic. | Up to 6 months after consent is obtained | |
Secondary | Probability of concurrence of multiple non-motor features | The concurrence of multiple non-motor symptoms will be assessed using a multinomial logistic regression model to determine if a distinct combination of non-motor symptoms is more prevalent in the cervical dystonia patient group than in the unaffected family members or healthy volunteer groups. | Up to 6 months after consent is obtained |
