OBJECTIVE Five styles of commercial static wrist extensor orthoses were compared to determine whether any style, or styles, afforded better power grip strength or finger dexterity. Because wrist extensor orthoses are intended for use during functional tasks, their influence on hand function is of great importance. METHOD Twenty-three right-hand-dominant women without upper extremity dysfuncti...

To control reaching, the nervous system must generate large changes in muscle activation to drive limb toward target, and also make smaller adjustments for precise accurate behavior. Motor cortex controls arm through projections diverse targets across central system, but it has been challenging identify roles of cortical specific targets. Here, we selectively disrupt cortico-cerebellar communic...

BACKGROUND AND PURPOSE Previous research has reported impaired hand function on the "unaffected" side after stroke, but its incidence, origins, and impact on rehabilitation remain unclear. This study investigated whether impairment of ipsilateral dexterity is common early after middle cerebral artery stroke and explored the relationship to cognitive deficit. METHODS Thirty patients within 1 m...

The Nine Hole Peg Test is commonly used by occupational therapists as a simple, quick assessment for finger dexterity. The purpose of this study was to evaluate the interrater and test-retest reliability of the commercially available Smith & Nephew Rehabilitation Division version of the Nine Hole Peg Test, and to establish new adult norms for the Nine Hole Peg Test for finger dexterity utilizin...

INTRODUCTION Conventional manual laparoscopic instruments for minimally invasive surgery have limited dexterity within the patient, making procedures challenging. Surgical robotic systems offer enhanced articulation, but at substantial financial costs. This has motivated the development of high-dexterity, low-cost laparoscopic instruments. AREAS COVERED This article reviews both commercial an...

Specific relations between executive functions (working memory capacity, planning and problem-solving, inhibitory control) and motor skill performance (anticipatory motor planning, manual dexterity) were examined in 5- to 6-year-old children (N = 40). Results showed that the two motor skill components were not correlated. Additionally, it was found that response planning performance was a signi...

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 Double-gloving in the performance of surgical procedures has been demonstrated to reduce the frequency of blood contact with the hands of members of the surgical team. Concerns persist that double-gloving can compromise the dexterity and tactile sensitivity of the surgeon. STUDY DESIGN Fifty-three surgeons and surgeons-in-training volunteered at the Clinical Congress of the America...
