fine adaptive precision grip control without maximum Pinch Strength changes after upper limb neurodynamic mobilization
Scientific Reports, 2021Co-Authors: Frédéric Dierick, Jean-michel Brismée, Olivier White, Anne-france Bouché, Céline Périchon, Nastasia Filoni, Vincent Barvaux, Fabien BuisseretAbstract:Before and immediately after passive upper limb neurodynamic mobilizations targeting the median nerve, grip ([Formula: see text]) and load ([Formula: see text]) forces applied by the thumb, index and major fingers (three-jaw chuck Pinch) were collected using a manipulandum during three different grip precision tasks: grip-lift-hold-replace (GLHR), vertical oscillations (OSC), and vertical oscillations with up and down collisions (OSC/COLL/u, OSC/COLL/d). Several parameters were collected or computed from [Formula: see text] and [Formula: see text]. Maximum Pinch Strength and fingertips pressure sensation threshold were also examined. After the mobilizations, [Formula: see text] max changes from 3.2 ± 0.4 to 3.4 ± 0.4 N (p = 0.014), d[Formula: see text] from 89.0 ± 66.6 to 102.2 ± 59.6 [Formula: see text] (p = 0.009), and d[Formula: see text] from 43.6 ± 17.0 to 56.0 ± 17.9 [Formula: see text] ([Formula: see text]0.001) during GLHR. [Formula: see text] SD changes from 0.9 ± 0.3 to 1.0 ± 0.2 N (p = 0.004) during OSC. [Formula: see text] peak changes from 17.4 ± 8.3 to 15.1 ± 7.5 N ([Formula: see text]0.001), [Formula: see text] from 12.4 ± 6.7 to 11.3 ± 6.8 N (p = 0.033), and [Formula: see text] from 2.9 ± 0.4 to 3.00 ± 0.4 N (p = 0.018) during OSC/COLL/u. [Formula: see text] peak changes from 13.5 ± 7.4 to 12.3 ± 7.7 N (p = 0.030) and [Formula: see text] from 14.5 ± 6.0 to 13.6 ± 5.5 N (p = 0.018) during OSC/COLL/d. Sensation thresholds at index and thumb were reduced (p = 0.001, p = 0.008). Precision grip adaptations observed after the mobilizations could be partly explained by changes in cutaneous median-nerve pressure afferents from the thumb and index fingertips.

Fine adaptive control of precision grip without maximum Pinch Strength changes after median nerve mobilization
2020Co-Authors: Frédéric Dierick, Jean-michel Brismée, Olivier White, Anne-france Bouché, Céline Périchon, Nastasia Filoni, Vincent Barvaux, Fabien BuisseretAbstract:ABSTRACT Fine dexterity critically depends on information conveyed by the median nerve. While the effects of its compression and vibration are well characterized, little is known about longitudinal tension and excursion. Using a force-sensitive manipulandum, a numeric dynamometer and Semmes-Weinstein monofilaments, we examined the adaptations of precision grip control, maximum Pinch Strength and fingertips pressure sensation threshold before and immediately after the application of longitudinal tension and excursion mobilizations applied on the median nerve. Grip (GF) and load (LF) forces applied by the thumb, index and major fingers were collected in 40 healthy young participants during three different grip precision tasks along the direction of gravity. For grip-lift-drop task, maximum GF and LF and their first time derivatives were computed. For up-down oscillations, means of GF and LF and their variability were computed. For oscillations with up and down collisions, peaks of GF and LF, time delay between GF peak and contact, and values of GF and LF at contact were collected. Our findings show that median nerve mobilizations induce significant fine adaptations of precision grip control in the three different tasks but mainly during grip-lift-drop and oscillations with collisions. Fingertips pressure sensation thresholds at index and thumb were significantly reduced after the mobilizations. No significant changes were observed for maximum Pinch Strength. We conclude that precision grip adaptations observed after median mobilizations could be partly explained by changes in cutaneous median-nerve mechanoreceptive afferents from the thumb and index fingertips.

body composition and weakness of hand grip Strength and Pinch Strength in patients with chronic kidney disease from different ethnic backgrounds
Journal of Human Nutrition and Dietetics, 2021Co-Authors: Keruo Jiang, Adrian Slee, Andrew DavenportAbstract:BACKGROUND Chronic kidney disease (CKD) patients commonly report muscle weakness and fatigue. Losing muscle mass increases mortality. Accordingly, we aimed to determine the main factors associated with loss of muscle mass and muscle weakness. METHODS Anthropometric measurements were made in CKD patients attending a specialised clinic, along with hand grip Strength (HGS), Pinch Strength (PS) and body composition (muscle mass and fat mass), using segmental bioimpedance assessment. RESULTS We reviewed the results of 161 CKD patients; 105 male (65.2%), mean (SD) age 70.3 (15) years, body mass index (BMI) 28.8 (6.7) kg m-2 . In multivariable models, both HGS and PS were independently negatively associated with age [standardised β (St β) = 0.35; 95% confidence limits (CL) = -0.32 to -0.14; St β = 0.38; 95% CL = -0.65 to -0.02; P < 0.001, respectively] and positively with appendicular muscle in the arm tested [St β = 0.34; 95% CL = 2.5-6.3; St β = 0.24; 95% CL = 0.17-0.98; P < 0.001 and P = 0.006, respectively]. In addition, HGS was associated with male gender (St β = 0.19; 95% CL = 0.7-7.5; P = 0.019] and negatively with percentage body fat (St β = 0.22; 95% CL = -0.36 to -0.07; P = 0.003]. There were 47 (29.2%) Asian patients who had lower total skeletal muscle mass/height ratio and appendicular muscle mass/BMI ratio compared to other ethnicities [9.6 (1.8) versus 10.5 (1.6) kg m-2 , P < 0.01; 0.73 (0.23) versus 0.83 (0.33) m2 ; P < 0.01). CONCLUSIONS In CKD patients, we found that muscle weakness measured by HGS and PS was associated with increasing age and loss of appendicular muscle mass. HGS was also weaker with increasing fat mass and female gender, whereas PS was weaker in patients of Asian ethnicity.

differences between anthropometric and bioimpedance measurements of muscle mass in the arm and hand grip and Pinch Strength in patients with chronic kidney disease
Clinical Nutrition, 2021Co-Authors: Keruo Jiang, Sarju Raj Singh Maharjan, Adrian Slee, Andrew DavenportAbstract:Summary Background & aims Chronic kidney disease (CKD) patients are at increased risk of sarcopenic muscle wasting, with increased mortality risk. Simple screening tests are required to detect sarcopenia to allow for interventional therapies. We wished to compare anthropometric and multifrequency bioimpedance (MFBIA) measurements of arm composition and muscle Strength. Methods We measured segmental MFBIA, mid arm upper circumference (MUAC) and triceps skin fold thickness (TSF), hand grip Strength (HGS) and Pinch Strength (PS) in CKD patients attending out-patient review. Results We reviewed 146 patients; 94 male (64.4%), 93 (63.7%) diabetic, mean age 70.5 ± 15 years, weight 77.6 ± 17.1 kg, with a mean HGS of 25.2 ± 10.4, and PS 5.0 ± 1.9 kg. HGS and PS were correlated (r = 0.63, p Conclusions In CKD patients, segmental MFBIA measurements of the arm, but not those derived from anthropometric measurements demonstrate gender differences and correlate with arm muscle Strength, whereas there were no such correlations with anthropometric estimates of upper arm muscle or fat.

effect of self reported distress thermometer score on the maximal handgrip and Pinch Strength measurements in hemodialysis patients
Nutrition in Clinical Practice, 2017Co-Authors: Stephanie Camilleri, Stephanie Chong, Kamonwan Tangvoraphonkchai, Suree Yoowannakul, Andrew DavenportAbstract:Background: Muscle weakness is a risk factor for mortality in hemodialysis (HD) patients. Muscle Strength measurements are routinely used as a screening tool but depend on patient cooperation and motivation. We wished to determine whether measuring maximal voluntary muscle Strength was affected by patient self-reported distress. Methods: We measured Pinch Strength (PS) and handgrip Strength (HGS) in 382 adult HD patients with a corresponding self-reported distress thermometer (DT) scores. Postdialysis body composition measurements were made using multifrequency bioelectrical assessments and patients assessed for frailty. Results: Mean age was 66.4 ± 14.9 years, with 238 males (62%), 48% diabetic, and dialysis vintage 36 (15–75) months. The mean DT score was 4.4 ± 3.3, with a frailty score of 4.6 ± 1.5. On multivariable analysis, DT scores were associated with frailty (β = 0.35, P = .003), prescription of aspirin for cardiac disease (β = 1.0, P = .004), lean body mass (β = 0.04, P = .004), and negatively w...

Prevalence of the palmaris longus muscle and its relationship with grip and Pinch Strength: a study in a Turkish pediatric population
HAND, 2013Co-Authors: A Cetin, M Genc, S Sevil, Yusuf Kenan CobanAbstract:Clinical studies generally reveal a trend of variation in the reported prevalence of the palmaris longus (PL) muscle absence. The aim of this study was to find an answer to the question of whether the congenital absence of tendon would affect hand functions or not. A total of 585 subjects, comprised of 305 males and 280 females, were included in our study. Mean age was 8.9 ± 1.4 standard deviation within a range of 6–11. For both sexes, the groups were divided further into three subgroups including 6–7, 8–9, and 10–11 years of age ranges. The grip Strength of each hand and Pinch Strength of all fingers of each subject were measured separately. The absence of PL tendon in the right hand was 35.4 % in females, 25.9 % in males, and 30.4 % in overall average. The distribution of absence of the palmaris longus muscle between both genders was statistically significant. The p value for the right hand was 0.013. The absence of PL tendon in the left hand was 37.5 % in females, 27.9 % in males, and an overall average of 32.5 %. The p value for the left hand was 0.017. In terms of grip Strength, a comparison between females and males did not reveal a significant difference. The Pinch Strength of the second fingers of both hands did not show any difference in both sexes. Pinch Strength of the third finger of the right hand was different only in girls of subgroup 6–7 ages ( p = 0.024). In girls, the Pinch Strength of the fourth finger of the right hand of subgroups 6–7 and 10–11 ages showed difference ( p = 0.009 and p = 0.026, respectively). In boys, the fourth finger in subgroup of 8–9 ages showed significant difference in both hands ( p = 0.011). The fifth fingers of both hands were found different in males for only subgroup of 8–9 ages ( p = 0.001). Pinch Strength of the fifth finger of the right hand was different in females for only subgroups of 6–7 and 10–11 ages ( p = 0.023 and p = 0.047, respectively). While grip Strength of the hand was not affected in the case of absence of the palmaris longus, in both sexes, Pinch Strength of the fourth and fifth fingers of both hands decreased.
