“…Although gender differences in dexterity have been documented in childhood and young to middle adulthood, few studies have examined this issue in older adulthood. In contrast, recent findings by Sebastjan, Skrzek, Ignasiak, and Slawinska (2017) showed more decline in older females in tapping and peg inserting tasks. Another important issue is whether there are gender differences in manual dexterity decline in older adults.…”

This study aimed to better characterize age-related differences in dexterity by using an integrative approach where movement times and kinematics were measured for both hands. Forty-five young (age 19-31) and 55 healthy older adults (age 60-88) were evaluated during unimanual and bimanual performance of the Purdue Pegboard Test. Gender effects were also assessed. From video-recorded data, movement times and kinematics were obtained for reaching, grasping, transport, and inserting. Results showed that older adults had longer movement times for grasping and inserting with the right hand, and across all movements with the left hand. Kinematic differences were found in path length, linear, and angular velocity. The patterns of slowing were similar in unimanual and bimanual tasks. Gender effects showed more slowing in older males than older females. Age differences in dexterity not only comprise slowing of movements but also kinematic alterations. The importance of gender in hand function was demonstrated.

“…In the latter studies, more decline has been found in older males, as shown by longer time needed to manipulate pegs in the Purdue Pegboard tasks. In contrast, recent findings by Sebastjan, Skrzek, Ignasiak, and Slawinska (2017) showed more decline in older females in tapping and peg inserting tasks.…”

“…Centrally, ageing has been related to impaired efficiency of feedback processing of sensory information to guide limb target control (Ribeiro and Olivera, 2007 ; Goble and Anguera, 2010 ). Age-related physiological and anatomical degenerative effects such as changes in motor unit size, properties, control and morphology as well as altered inputs from the nervous system, can lead to reduced neural control affecting fine motor performance (Erim et al, 1999 ; Hunter et al, 2016 ; Sebastjan et al, 2017 ). With age, motor units reduce in number and become larger in size (Larsson and Ansved, 1995 ; Ling et al, 2009 ; Hunter et al, 2016 ).…”

Perception of limb and body positions is known as proprioception. Sensory feedback, especially from proprioceptive receptors, is essential for motor control. Aging is associated with a decline in position sense at proximal joints, but there is inconclusive evidence of distal joints being equally affected by aging. In addition, there is initial evidence that physical activity attenuates age-related decline in proprioception. Our objectives were, first, to establish wrist proprioceptive acuity in a large group of seniors and compare their perception to young adults, and second, to determine if specific types of training or regular physical activity are associated with preserved wrist proprioception. We recruited community-dwelling seniors (n = 107, mean age, 70 ± 5 years, range, 65–84 years) without cognitive decline (Mini Mental State Examination-brief version ≥13/16) and young adult students (n = 51, mean age, 20 ± 1 years, range, 19–26 years). Participants performed contralateral and ipsilateral wrist position sense matching tasks with a bimanual wrist manipulandum to a 15° flexion reference position. Systematic error or proprioceptive bias was computed as the mean difference between matched and reference position. The respective standard deviation over five trials constituted a measure of random error or proprioceptive precision. Current levels of physical activity and previous sport, musical, or dance training were obtained through a questionnaire. We employed longitudinal mixed effects linear models to calculate the effects of trial number, sex, type of matching task and age on wrist proprioceptive bias and precision. The main results were that relative proprioceptive bias was greater in older when compared to young adults (mean difference: 36% ipsilateral, 88% contralateral, p < 0.01). Proprioceptive precision for contralateral but not for ipsilateral matching was smaller in older than in young adults (mean difference: 38% contralateral, p < 0.01). Longer years of dance training were associated with smaller bias during ipsilateral matching (p < 0.01). Other types of training or physical activity levels did not affect bias or precision. Our findings demonstrate that aging is associated with a decline in proprioceptive bias in distal arm joints, but age does not negatively affect proprioceptive precision. Further, specific types of long-term dance related training may attenuate age-related decline in proprioceptive bias.

“…Studies have shown that dominant hand use is associated with fine motor skills. In addition, studies have shown that there are significant differences between dominant and non-dominant hand regarding asymmetry, the number of hits and the completion time (5). Strength of hand grip and motion perception are associated with muscle strength in the upper extremity.…”

Amaç: El dominansı; sağ dominant, sol dominant veya bilateral el kullanılması şeklinde görülmektedir. Sağ dominant bireylerin çoğunlukta olduğu toplumumuzda dominant ve non dominant tarafta tekrarlı hareketlerin hareket algısı ve motor öğrenmeye etkisinin incelenmesi ve yorumlanabilmesi amacıyla bu çalışma planlanmıştır. Yöntemler: Çalışmaya yaş ortalaması 23±1,99 yıl olan, 80'i kadın (%54,79), 66'i erkek (%45,21) olmak üzere 146 gönüllü sağ eli dominant olan üniversite öğrencisi katıldı. El tercihi Edinburg El Tercih Anketi ile değerlendirildi. Bireyler kalça, diz ve dirsekler 90⁰ fleksiyonda olacak şekilde masa kenarında pozisyonlandı. Ölçümler özel platform üzerinde yapıldı. Bireylerden, gözler kapalı iken, uzaklık ölçerden 25 cm mesafedeki merkez noktaya bardağı yerleştirmesi istendi. Ölçümler 3 kez dominant ve non dominant tarafta tekrarlandı. Merkez noktaya uzaklık ve sapma miktarı lazerli uzaklık ölçer ile cm cinsinden kaydedildi. İstatistiksel analizler sırasında SPSS 21.0 kullanıldı. Bulgular: Edinburg El tercih anketine göre bireylerin 42'ı (%28,76) kuvvetli sağ dominant, 90'ı (%65,06) zayıf sağ dominant, 9'u (%6,18) zayıf sol dominanttı. Bardak yerleştirme aktivitesi sırasında merkez noktadan uzaklıkların üç ölçüm için ortalaması dominant tarafta 2,56±1,91 cm, non dominant taraf için ise 2,57±1,87 cm'di. Dominant ve non-dominant el açısından merkez noktadan uzaklık ölçümleri açısından anlamlı fark bulunmadı (p>0,05). Ancak dominant tarafta ardı ardına yapılan üç ölçümün merkezden sapmaObjective: Hand dominancy can be observed as right-dominancy, leftdominancy or the usage of bilateral hands. In Turkish population, the majority of individuals have right-hand dominance. This study was planned in order to examine and interpret the motion perception and motor learning of the upper extremity dominant and non-dominant side. Methods:The study was carried out with 146 volunteer university students with right-hand dominancy. The mean age of the participants was 23.0 ± 1.99, 80 of them were female (54.79%), and 66 of them were male (45.21%). Hand preference was evaluated by the Edinburgh Hand Preference Questionnaire. The participants were positioned at the table edge with the hip, knee, and elbows at 90 degrees flexion. Measurements were made on a special platform. The participants were asked to place the glass at the center point, which is distance from 25 cm the rangefinder, while the eyes were closed. The measurements were repeated 3 times on both the dominant and non-dominant sides. The distance and deviation rate from the center point were recorded in cm with the laser rangefinder. SPSS 21.0 program was used in the analysis. Results: According to the Edinburg Hand Preference Questionnaire, 42 of the individuals (28.76%) were strong right dominant, 95 (65.06%) were weak right dominant, and 9 (6.18%) were weak left dominant. The mean of distance from the central point for the three measurements during the activity of glass placing were 2.56 ± 1.91
