Objective: To investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic Parkinson’s disease (PD). Materials and methods: In this cross-sectional study, 55 patients with idiopathic PD by mean age of 59.85 ± 11.89 years, and mean Hoehn and Yahr stage ...

UNLABELLED BACKGROUND AND PURPOSE; Previous work indicated that patients within 1 month of parietal or posterior frontal damage are often abnormally slow or clumsy when using the ipsilateral hand for dexterity tasks. This article reports a 6-month follow-up study to assess recovery and the impact on functional outcome. METHODS Twenty-four patients (80%) were available for follow-up. They used...

We have developed a method to quantify the dynamic interaction between fingertip force magnitude (strength) and directional control (dexterity) during pinch with a novel strength-dexterity (S-D) test based on the principle of buckling of compression springs. The test consists of asking participants to use key and opposition pinch to attempt to fully compress springs, in random order, with a wid...

[Purpose] The purpose of this study was to investigate how a time limit affects day-to-day tasks such as attention, hand dexterity, and sit to standing and sitting activity. The grounds for using a time limit as a method of learning tasks related to daily living are examined based on the results of this investigation. [Subjects and Methods] The subjects consisted of 51 healthy college students ...

BACKGROUND Multiple Sclerosis (MS) is the most common disabling neurological disease. Hand dysfunction is one of the main complaints of patients with MS. The present study aimed to compare hand dexterity of MS patients with low Expanded Disability Status Scale (EDSS) scores and healthy adults. It also sought to identify the predictors of disability status of patients with MS based on their manu...

BACKGROUND The ability to dynamically control fingertip force vector magnitude and direction is critical for dexterous manipulation. We quantified the dynamic control of fingertip forces to examine how dexterous manipulation declines with age. METHODS The strength-dexterity (SD) test measures fingertip forces during compression of a slender spring prone to instability and buckling. The greate...

AIM To investigate tactile perception and manual dexterity, with or without visual feedback, in males with Duchenne muscular dystrophy (DMD). METHOD Forty males with DMD (mean age 9 y 8 mo, SD 2 y 3 mo; range 5-14 y), recruited from the teaching hospital of the School of Medicine of the University of São Paulo, with disease severity graded as '1' to '6' on the Vignos Scale and '1' on Brooke's...

[Purpose] The purpose of this study was to evaluate the relationship between daily activities and manual dexterity in persons with Parkinson disease. [Subjects and Methods] The study participants were 25 patients with idiopathic Parkinson disease. This study used two clinical tools, the box-and-block test and Schwab and England Activities of Daily Living scale, to investigate the relationship b...

Objectives: The present study aimed to investigate the possible effects of laterality and handedness on higher-order sensory functions and manual dexterity of the elderly. Methods: In this non-experimental cross-sectional study, 58 elderly people aged 60-75 years (35 right-handed) were recruited through a convenience sampling method. Laterality of the selected subjects was examined using the E...
