Smart switching in feedforward control of grip force during manipulation of elastic objects

2017

AbstractSwitching systems are common in artificial control systems. Here, we suggest that the brain adopts a switched feedforward control of grip forces during manipulation of objects. We measured how participants modulated grip force when interacting with soft and rigid virtual springs when stiffness varied nearly continuously between trials. We identified a sudden phase transition between two forms of feedforward control that differed in the timing of the synchronization between the anticipated load force and the applied grip force. The switch occurred several trials after a threshold stiffness level. These results suggest that in the control of grip force, the brain acts as a switching c…

A Randomized Trial Assessing the Muscle Strength and Range of Motion in Elderly Patients following Distal Radius Fractures Treated with 4- and 6-Week…

2021

Background: There is no consensus among orthopedic surgeons as to the required period of cast immobilization in distal radius fractures in elderly patients. The purpose of this study was to assess muscle strength and range of motion symmetry in elderly patients after distal radius fractures with different periods of cast immobilization. Methods: This study evaluated 50 patients (33 women and 17 men), aged over 65 years, after cast immobilization treatment for distal radius fracture. The mean age at the beginning of treatment was 71 years. The mean duration of follow-up was 1 year and 3 months. The first subgroup (n = 24) comprised the patients whose fractures had been immobilized in a cast …

El Gran Catharro de 1580 ¿gripe o pertussis?

2005

The gran Catharro (1580) is considered the first influenza epidemic. The analysis of various testimonies of the time may offer some doubts about whether or not it was so; and data strongly support that it was a pertussis epidemic.

G6PD Overexpression Protects Mice Against Associated Oxidative Stress and Delays the Occurrence of Frailty

2016

To assess the impact of lifelong overexpression of G6PD on reactive oxygen species (ROS)-derived damage and the prevention of frailty, we measured the levels of macromolecular oxidative damage in young and old mice and the we tested the neuromuscular fitness and the grip strength in old mice. Old G6PD-Tg male and female mice showed diminished accumulation of DNA oxidation (measured as 8-hydroxyguanosine or 8-OHdG) in liver and brain. Old females also showed reduced lipid oxidation (measured as malondialdehyde or MDA) in the liver. Old G6PD-Tg males, but not females, presented a small but significant increase in brain protein carbonylation. In accordance with these findings, liver from 2-yea…

Rapid Weight Loss Alters Handgrip Strength In Greco-Roman Wrestlers

Effects of rapid weight loss (RWL) on handgrip strength (HGS) in combat sports athletes are still quite indefinite. The aim of this study was to delineate the effect of RWL on HGS in Greco-Roman wrestlers. Handgrip strength was measured during three time points. Baseline measurement was carried out before the weight reduction. Second measurement was done after sport specific training combined together with RWL. Finally, third measurement was carried out after sport specific training alone. Results showed that HGS was significantly greater after a training combined with RWL procedure compared to only specific training for one hand. Findings of this study could potentially improve the trainin…

La epidemia de gripe de 1918 y los profesionales de Enfermería. Análisis a través de la prensa española

2016

La epidemia de gripe de 1918 es considerada una de las más letales de la historia de la humanidad, ocasionando una alta morbilidad y mortalidad que quedó reflejada en la prensa española. Por ello, consideramos necesario abordar los acontecimientos relativos a la epidemia desde la perspectiva periodística, centrándonos especialmente en la relación de la enfermedad con los profesionales de Enfermería. Para llevar a cabo dicha investigación, se seleccionaron diez cabeceras españolas (ABC, El Globo, El Heraldo de Madrid, El Imparcial, El País, El Sol, La Acción, La Correspondencia de España, La Época y La Vanguardia) desde el 1 de enero de 1918 hasta el 31 de diciembre de 1920, extractándose to…

RELAZIONE TRA HANDGRIP E FAMILIARITÀ AL DIABETE DI TIPO 2: UNO STUDIO PILOTA/ RELATIONSHIP BETWEEN TYPE 2 DIABETES AND HANDGRIP: RESULTS OF A PILOT S…

2012

Obiettivo: È stata analizzata la possibile relazione, su un campione della popolazione siciliana, tra il grado di familiarità al diabete di tipo 2, i parametri antropometrici ed alcuni test di forza specifica. Materiali e metodi: In modalità random sono stati selezionati 88 uomini e 27 donne, distinti in FH- (assenza di familiarità per il diabete di tipo 2), FH+ (con un componente in linea indiretta con la malattia) ed FH++ (con un genitore affetto dalla malattia). Sono stati rilevati i parametri antropometrici, i parametri cardiovascolari ed è stato rilevato l’handgrip ad entrambe le mani. Le differenze tra i gruppi sono state analizzate con il test ANOVA ed attraverso correlazioni paramet…

Improvement of the expression of upper limb muscle strength and balance in a group of patients with multiple sclerosis, through a proprioceptive reha…

2022

In multiple sclerosis (MS) patients, symptoms such as: fatigue, lack of physical energy, spasticity, difficulty in performing movements, and motor coordination disorders, and with tremors, dizziness and postural instability are among the most common complications. Cattaneo et al. (2007) studied the effects of stability training on MS patients and described it as an effective intervention in reducing falls risk, improving stability, and strength. Therefore, the present study aimed to confirm early observations by the application of a proprioceptive rehabilitation program targeting balance and strength on MS patients. 13 subjects with MS, 5 male and 8 female, volunteered in the study. A MAP h…

Patisiran Enhances Muscle Mass after Nine Months of Treatment in ATTRv Amyloidosis: A Study with Bioelectrical Impedance Analysis and Handgrip Streng…

2022

Background and aims. Hereditary transthyretin amyloidosis with polyneuropathy (ATTRv) is caused by mutations in the TTR gene, leading to misfolded monomers that aggregate generating amyloid fibrils. The clinical phenotype is heterogeneous, characterized by a multisystemic disease affecting the sensorimotor, autonomic functions along with other organs. Patisiran is a small interfering RNA acting as a TTR silencer approved for the treatment of ATTRv. Punctual and detailed instrumental biomarkers are on demand for ATTRv to measure the severity of the disease and monitor progression and response to treatment. Methods. Fifteen patients affected by ATTRv amyloidosis (66.4 ± 7.8 years, six males) …
