Changes in hand morphology throughout human evolution have facilitated the use of forceful pad-to-pad precision grips, contributing to development fine motor movement and dexterous manipulation typical modern humans. Today, variation function may be affected by demographic and/or lifestyle factors, but these remain largely unexplored. We measured pinch grip strength dexterity a heterogeneous cr...

BACKGROUND Impaired dexterity of the weaker upper extremity is common post stroke and it is recommended that these individuals practice many repetitions of movement to regain function. However, stroke rehabilitation methods do not achieve the required intensity to be effective. Touchscreen tablet technology may be used as a motivating tool for self-training impaired dexterity of the weaker uppe...

BACKGROUND Intermittent theta burst stimulation (iTBS) is a repetitive transcranial magnetic stimulation (rTMS) protocol that influences cortical excitability and motor function recovery. OBJECTIVES This study aimed to investigate the effects of iTBS on manual dexterity and hand motor imagery in multiple sclerosis (MS) patients. METHODS Thirty-six MS patients were non-randomly assigned into...

The concept of dexterity and its dimensions have been difficult to define through the years, and various research communities have different definitions of dexterity. In this paper, we present a novel approach to understand people’s perception of dexterity and its different dimensions in daily tasks. The approach entails a video-based survey where people score different tasks along pre-specifie...

BACKGROUND Mood disorders are associated with various neurocognitive deficits. However, few studies have reported the impairment of motor dexterity in unipolar depression and bipolar disorder. In the present study, manual dexterity was compared between unipolar major depression, bipolar disorder, and healthy controls. METHODS Manual dexterity was assessed by the Purdue pegboard test in 98 pat...

Background: Dysgraphia as a problem with handwriting, affects student's performance in school activities and participation. The purpose of the study was to compare dexterity and two-point discrimination of the hand between learning disabled students with dysgraphia and healthy students. Methods: Forty-three students with developmental dysgraphia and 55 normal students in grade two to four from ...

[Purpose] The aim of this study was to investigate the effects of repeated vibratory stimulation to muscles related to hand functions on dexterity, strength, and sensory function in patients with chronic stroke. [Subjects and Methods] A total of 10 stroke patients with hemiplegia participated in this study. They were divided into two groups: a) Experimental and b) Control, with five randomly se...

The purpose of this study was to investigate manual performance and thermal responses during low work intensity in persons wearing standard protective clothing in the petroleum industry when they were exposed to a range of temperatures (5, –5, –15 and –25°C) that are relevant to environmental conditions for petroleum industry personnel in northern regions. Twelve men participated in the study. ...
