“…In addition, both the Y20 and O70 were significantly faster than their own Time on Day 1 while the O80 group demonstrated no significant changes in time to complete the task across 5 days of practice. Our findings support the many studies that have shown that with practice both young and older adults improve in fine movement skills (e.g., Bock and Schneider, 2002 ; Kennedy and Raz, 2005 ; Rodrigue et al, 2005 ; Seidler, 2007 ; Voelcker-Rehage, 2008 ) and also in isometric force control tasks ( Lazarus and Haynes, 1997 ; Voelcker-Rehage and Alberts, 2005 ; Poston et al, 2008 ; Camus et al, 2009 ; Sosnoff and Voudrie, 2009 ; Francis et al, 2012 ).…”

“…These segments were a factor that was included in the analysis, but they were not visible and were thus unknown to the participants. Our previous research has consistently shown that more errors are made and more time taken to approach the target or to reverse force direction ( Spirduso et al, 2005b ; Griffin et al, 2009 ; Eakin et al, 2012 ; Francis et al, 2012 ; Herring-Marler et al, 2014 ).…”

“…Thus, inter-manual asymmetry was more sensitive to changes in difficulty than the age factor was. Segment 3 is difficult because it requires the anticipation of a reversal of force direction ( Spirduso et al, 2005b ; Griffin et al, 2009 ; Eakin et al, 2012 ; Francis et al, 2012 ; Herring-Marler et al, 2014 ) approaching a target (Reverse Circle), requirements that are known to slow down the approach and induce errors ( Salthouse, 1985 ). Segments 4 through 6 require the controlled release of force, known to be more difficult than controlled application of force which occurs in Segment 2 and Segment 3 ( Spirduso and Choi, 1993 ).…”

“… Poston et al (2008) , also found that the left hand of older adults exhibited greater errors than those of young on the first day of practice, but these differences were eliminated by two additional days of practice, whether the practice was with the right or the left hand. Conversely, several other investigators, providing multiple trials over more than 1 day showed that older adults improved dynamic isometric force control tracing and tracking when they performed and practiced with one hand, but not as much as young adults improved ( Spirduso and Choi, 1993 ; Lazarus and Haynes, 1997 ; Voelcker-Rehage and Alberts, 2005 ; Francis et al, 2012 ). Lazarus and Haynes (1997) found no age differences in the transfer of information from one hand to the other in a transfer of training paradigm requiring participants to track isometrically a randomly generated template.…”

Manual dexterity declines with increasing age, however, the way in which inter-manual asymmetry responds to aging is unclear. Our purpose was to determine the effect of age and practice on inter-manual performance asymmetry in an isometric force pinch line tracing task that varied in difficulty within segments. Thirty right-handed participants, five males and five females in each of three age groups, young (Y20), young–old (O70), and old–old (O80), practiced an isometric force pinch task for 10 trials with each hand on each of five consecutive days. Inter-manual performance asymmetry of the right and left hands was analyzed with a repeated measures analysis of variance (ANOVA) of asymmetry with age groups, practice, task difficulty, and hand as factors. The within-individual magnitude of asymmetry was also analyzed with a repeated measures ANOVA of manual asymmetry calculated as an asymmetry index (AI). Post hoc pair-wise comparisons were performed when significance was found. We observed no inter-manual performance asymmetry on this isometric tracing task among any of the age groups, either in the hand performance differences or in the magnitude of the AI. Age and practice interacted in terms of manual performance: the Y20 and O70 group improved accuracy and task time across the 5 days of practice but the O80 group did not. However, practice did not differentially affect the AI for accuracy or task time for any group. Accuracy of performance of the two hands was differentially affected by practice. All age groups exhibited poorer performance and larger AIs on the most difficult segments of the task (3 and 6) and this did not change with practice.

Cerebro-vascular disorders are among the top 10 causes of death in children, with rates highest in the first year of life. Childhood stroke is the weakness of one side of the body due to stroke during 3 months to 12 years of age. Learning or re-learning tasks are significant elements of the rehabilitation process for a child with a neurological or orthopedic impairment. Although many studies have been conducted to see the effects of ipsilateral hand training on the contralateral hand using inter-manual transfer in normal population but there is a dearth of studies to see the effect on inter-manual training of hand on skill transfer in childhood stroke patients. Hence, present research was carried out to study the effect of inter-manual transfer training of hand on skill transfer in childhood stroke in terms of motor learning.

Age-related changes in force generation have been implicated in declines in older adult manual dexterity. While force generation is a critical aspect of the successful manipulation of objects, the controlled release of force represents the final component of dexterous activities. The impact of advancing age on the release of grip force has received relatively little investigation despite its importance in dexterity. The primary aim of this project was to determine the effects of age on the control of force release during a precision grip tracking task. Young adults (N = 10, 18–28 years) and older adults (N = 10, 57–77 years) completed a ramp-hold-release (0–35% of maximum grip force) force tracking task with their dominant hand. Compared to young adults, older adults were disproportionately less accurate (i.e., less time within target range) and had more error (i.e., greater relative root mean squared error) in the release of force, compared to generation of grip force. There was a significant difference between groups in two-point discrimination of the thumb, which was moderately correlated to force control across all phases of the task. The decline in force release performance associated with advanced age may be a result of sensory deficits and changes in central nervous system circuitry.
