The aim of the present study was to observe the changes in hand flexibility of patients with Parkinson's disease (PD) and the effect of dual-task interference. Patients with PD were distributed into two subgroups: the leucine-rich repeat kinase 2 (LRRK2) mutation PD (LRRK2+) and the LRRK2 mutation-free (LRRK2-) PD groups. The healthy controls were distributed into two subgroups: the LRRK2+ cont...

Background: Hand grip strength (HGS) is a reliable indicator of peripheral muscle strength. Although, numerous studies have investigated the strength of hand grip; little attention has been given to coronary artery disease (CAD) patients, exploring the relationship between HGS and myocardial oxygen consumption (MVO2) index. The current study aimed to evaluate the interaction between HGS and MVO...

A study of neuropsychological performance was conducted in 33 HIV+ patients initiating highly active antiretroviral therapy (HAART). Grooved Pegboard (GP) non-dominant hand performance improved in 23/33 (70%) subjects (P=0.002). Among 23 patients with motor slowing (GP non-dominant hand z score < -1.0) at baseline, 18 (78%) improved on the GP non-dominant hand test after initiating HAART (P=0.0...

UNLABELLED Grip strength dynamometers often are used to assess hand function in children. The use of normative grip strength data at followup is difficult because of the influence of growth and neuromuscular maturation. As an alternative, infant welfare centers throughout the world use growth diagrams to observe normative growth. The aim of this study was to develop similar growth diagrams for ...

The concepts of "good" and "bad" are associated with right and left space. Individuals tend to associate good things with the side of their dominant hand, where they experience greater motor fluency, and bad things with their nondominant side. This mapping has been shown to be flexible: Changing the relative fluency of the hands, or even observing a change in someone else's motor fluency, resul...
