Effects of wrist oscillations on contralateral neurological postural tremor using a new myohaptic device ('wristalyzer')

2007

Upper limb postural tremor consists of distinct oscillations, mainly mechanical-reflex and central-neurogenic. These oscillations are superimposed upon a background of irregular fluctuations in muscle force. Muscle spindles play key-roles in the information flow to supra-spinal and spinal generators. Oscillations were delivered using a new generation portable myohaptic device, called 'wristalyzer', which takes into account the ergonomy of upper limbs allowing a fine adjustment to each configuration of upper limb segments. The nominal torque of the device is 4 Nm, with a maximal rotation velocity of 300 degrees/s and a range of motion of +45 to -45 degrees. Reliability was assessed in basal …

Effect of training level and blood flow restriction on thermal parameters: Preliminary study

2016

Abstract Training with blood flow restriction could lead to an effect on skin temperature. Additionally, this effect could be higher in people with lower physical fitness level due to their lower capacity of heat loss. The aim of this preliminary study was therefore to evaluate the effects of training experience on the acute and chronic thermal skin responses after performing exercise with and without blood flow restriction. The study included ten men, of these, five were trained. All subjects performed tests and re-tests for maximum strength (1 repetition maximum) through unilateral leg extensions (right thigh at 45 ± 6.7 kg and left thigh at 45.5 ± 8.1 kg, p > 0.05). The protocol consiste…

Biomechanical evaluation of a new treatment method for distal tibia fractures

2015

Distal tibial fractures are often the result of high-energy impacts combined with excessive soft tissue injury. Treatment options include either open reduction and internal fixation usually as a mi...

Impact accelerations during a prolonged run using a microwavable self-customised foot orthosis

2021

The use of custom-made foot orthoses has been associated with numerous benefits, such as decreased impact accelerations. However, it is not known whether this effect could be due to better customisation. The present study analysed the effects of the first generation of  a microwavable prefabricated self-customised foot orthosis vs. a prefabricated standard one on impact accelerations throughout a prolonged run. Thirty runners performed two tests of 30-min running on a treadmill, each one with an orthosis condition. Impact acceleration variables of tibia and head were recorded every 5 min. Microwavable self-customised foot orthosis increased the following variables in the first instants comp…

The effects of a calisthenics training intervention on posture, strength and body composition

2017

BACKGROUND: Calisthenics was a term used to define a generic set of body weight exercises. Such term is now used to define a world wide spread discipline based on body weight and gymnastics exercises.OBJECTIVE: The aim of this study was to administer a calisthenics training protocol and evaluate its effects on posture, strength and body composition in untrained individuals.METHODS: Twenty-eight male participants (24.2 +/- 4.2 years; 67.0 +/- 8.3 Kg; 173.3 +/- 5.2 cm) were divided into two groups, a Calisthenics based intervention group (SG) and a control group (CG). The SG exercised for 8 weeks. Each participant underwent a body composition analysis, a postural assessment, a handgrip test, …

Modelling cardiac mechanics of left ventricular noncompaction

2020

Left ventricular noncompaction (LVNC) can be defined as a cardiomyopathy characterised by a pattern of prominent trabecular structure and deep intertrabecular recesses, that is thought to be caused by an arrest of normal endomyocardial morphogenesis. Using patient-specific computational modelling, we assessed the cardiac mechanics of five patients with LVNC and compared myocardial stress and pump performance to those of healthy controls. Findings shown that patients with LVNC have impaired left ventricular (LV) function, making it possible that the lack of fibre shortening of noncompacted layer can determine poor heart function. Pronounced end-systolic wall stress on left ventricular wall o…

Die Aktivität der Rückenstreckmuskulatur beim aufrechten Stehen und beim Sitzen mit standidentischer Rumpfhaltung - eine elektromyographische Studie

2001

Problem: There is a controversial discussion about the loading of the spine by the force of the extending muscles of the back in upright sitting with the back curved as in upright standing. Experimental studies investigating this issue are still lacking. Methods: In the study presented in this paper we measured in 30 subjects the activity of the extending back muscles both in a natural upright standing posture and in sitting with identical posture of the back as recommended in some back training programs. To this end we recorded the electromyographical surface activity of the back muscles at four levels of the spine in both postures. The EMG activities were intraindividually normalized with…

Real-world Adherence and Persistence with Bisphosphonate Therapy in Postmenopausal Women: A Systematic Review

2018

Abstract Purpose Bisphosphonate therapy is a well-established and effective treatment for postmenopausal osteoporosis and the prevention of osteoporotic fracture. However, poor adherence to and poor persistence with bisphosphonate therapy may reduce its benefits. Previous studies have documented the poor rates of adherence and persistence among postmenopausal women with osteoporosis. The objective of this systematic literature review was to evaluate adherence, persistence, and the impact of adherence and persistence on fracture risk in postmenopausal women with diagnosed osteoporosis. Methods Articles eligible for review included observational studies of the real-world use of bisphosphonate…
