Supplementary Material - Objective
To determine the benefits of motor training on the sequence effect (SE), an essential component of bradykinesia in Parkinson’s disease (PD).
Methods
Seven patients with de novo PD participated in this study. The patients performed regular pentagon drawing tests and exercises during four visits. The first two visits occurred before the start of medication, and the last two visits occurred at least six months after the start of medication. We assessed the severity of bradykinesia and SE at each visit and compared the results before and after exercise in both the de novo and treatment conditions.
Results
In the de novo condition, the severity of bradykinesia significantly improved after motor training (p = 0.018), but it did not resolve and only showed a trend of improvement after treatment (p = 0.068). The severity of the SE decreased significantly in the drug-naïve condition (p = 0.028) but not after medication (p = 0.273).
Conclusion
Our study suggests that regular motor training may be beneficial for the SE in PD. -

Abstract

- Objective
The aim of this subgroup analysis was to identify the risk factors associated with the development of various movement disorder phenotypes.
Methods
Eighty-three non-Wilsonian cirrhotic patients with abnormal movements were allocated into the following groups: intention tremor, bradykinesia, Parkinsonism, and abnormal ocular movements. These movement types were considered the primary outcomes as there was a sufficient sample size. Researchers took into consideration the gender, etiologies of cirrhosis, cirrhosis-related complications, hepatic encephalopathy, medical illness, and some neurological deficits as potential factors associated with these movement disorders.
Results
The male gender (p = 0.002) and alcoholic cirrhosis (p = 0.005) were significant factors for the prevalence of intention tremors. In bradykinesia, hepatic encephalopathy was highly statistically significant (p < 0.001), and females more commonly developed bradykinesia (p = 0.04). The Parkinsonism features in this study were confounded by hyperlipidemia (p = 0.04) and motor or sensory deficits (p = 0.02). Jerky pursuits and a horizontal nystagmus were detected. Jerky pursuits were significantly related to hepatic encephalopathy (p = 0.003) and bradykinesia, but there were no factors associated with the prevalence of nystagmus other than an intention tremor.
Conclusions
The association of alcoholic cirrhosis with the development of intention tremor indicates that the persistent cerebellar malfunction in cirrhotic patients is due to alcohol toxicity. The slowness of finger tapping and jerky pursuit eye movements are significantly associated with hepatic encephalopathy. Thus, further studies are needed to evaluate the diagnostic value of these two signs for an early detection of mild hepatic encephalopathy.

Abstract
PDF
Background and Purpose The sequence effect (SE) in Parkinson’s disease (PD) denotes progressive slowness in speed or progressive decrease in amplitude of repetitive movements. It is a well-known feature of bradykinesia and is considered unique in PD. Until now, it was well-documented in advanced PD, but not in drug-naïve PD. The aim of this study is to know whether the SE can also be measured in drug-naïve PD.
Methods We measured the SE with a computer-based, modified Purdue pegboard in 4 drug-naïve PD patients, which matched our previous study with advanced PD patients.
Results We observed progressive slowness during movement, that is, SE. Statistical analysis showed a strong statistical trend toward the SE with the right hand, but no significance with the left hand. There was no statistical significance of SE with either the more or less affected hands.
Conclusions These results indicate that the SE can be identified in drug-naïve PD, as well as in advanced PD, with objective measurements and support the idea that the SE is a feature in PD observed during the early stage of the disease without medication.
