Repetitive finger movement and circle drawing in persons with Parkinson's disease.

ABSTRACT: Little is known regarding how repetitive finger movement performance impacts other fine motor control tasks, such as circle drawing, in persons with Parkinson's disease (PD). Previous research has shown that impairments in repetitive finger movements emerge at rates near to and above 2 Hz in most persons with PD. Thus, the purpose of this study was to compare circle drawing performance in persons with PD that demonstrate impairment in repetitive finger movement and those that do not. Twenty-two participants with PD and twelve healthy older adults completed the study. Only participants with PD completed the repetitive finger movement task. From the kinematic data for the repetitive finger movement task, participants were grouped into Hasteners and Non-Hasteners. Participants with PD and the healthy older adults completed a series of circle drawing tasks at two different target sizes (1 cm and 2 cm) and three pacing conditions (Self-paced, 1.25 Hz, and 2.5 Hz). Kinematic and electromyography data were recorded and compared between groups. Results revealed that, in general, persons with PD demonstrate impairments in circle drawing and associated electromyography activity compared to healthy older adults. Moreover, persons with PD that hasten during repetitive finger movements demonstrate significantly increased movement rate during circle drawing, while those persons with PD that do not hasten demonstrate a significant increase in width variability. This suggests that differing motor control mechanisms may play a role in the performance of fine motor tasks in persons with PD. Continued research is needed to better understand differences in circle drawing performance among persons with PD to inform future development of patient-centered treatments.

Project description:BackgroundMuscle atrophy (MA) and muscle strength decline are important clinical features in chronic liver disease (CLD) patients. An easy to perform MA screening method without need for special equipment would be helpful. We evaluated the usefulness of the previously reported finger-circle test as screening for MA in CLD patients.MethodsWe retrospectively enrolled 358 Japanese CLD outpatients (70.8 ± 10.2 years, male/female = 234/124) who had undergone a computed tomography examination from December 2017 to March 2018, of whom 137 had chronic hepatitis, 169 had liver cirrhosis Child-Pugh A, and 52 had liver cirrhosis Child-Pugh B/C. Bilateral psoas muscle area at the middle of the third lumber vertebra (L3) was evaluated with computed tomography findings, which was performed as a screening of hepatocellular carcinoma, using a previously reported parameter for MA [psoas index (PI): total psoas muscle area (cm2 )/height (m)2 ] [mean PI ± standard deviation (SD) of male patients: 6.50 ± 1.13 cm2 /m2 and those of female patients: 4.30 ± 0.90 cm2 /m2 ]. We then evaluated the correlation between MA and finger-circle test results in these patients.ResultsThe mean PI values for finger-circle test results Bigger, Just-fits, and Smaller were 5.64 ± 1.34, 5.00 ± 1.25, and 4.83 ± 1.46 cm2 /m2 , respectively, in male patients (P < 0.001) and 4.31 ± 1.06, 3.93 ± 0.97, and 3.42 ± 0.94 cm2 /m2 , respectively, in female patients (P = 0.001). We found that a finger-circle test result in male patients other than Bigger (Just-fits and Smaller) predicted a decline in psoas muscle area of L3 to PI 5.25 cm2 /m2 (sensitivity/specificity 0.619/0.667, area under the curve 0.654, 95% confidence interval 0.583-0.724), which was approximately mean minus 1 SD (5.37 cm2 /m2 ). On the other hand, a Smaller test result in female patients predicted a decline in psoas muscle area of L3 to PI 3.33 cm2 /m2 (sensitivity/specificity 0.740/0.583, area under the curve 0.698, 95% confidence interval 0.583-0.813), approximately mean minus 1 SD (3.40 cm2 /m2 ).ConclusionsThe finger-circle test is an easy to perform and effective screening method for predicting earlier stage of MA in CLD patients without the need for special equipment.
