The use of accelerometers is discussed to evaluate standing vertical jump. Two accelerometers, mounted on each ankle and connected to a wearable system, were used for signal acquisition, and a piezoelectric platform was used to verify the results. Fifty-one subjects were enrolled, subdivided into a group of healthy subjects and 2 groups who had different(More)
A device capable of automatically detecting a fall with loss of consciousness (FloC), and activate an alarm by means of an accelerometer sensor is presented. Four hundred trials were performed by 20 participants (10 young and 10 elderly adults). The algorithm relies on the recognition of the effects of three events characterizing a FLoC: impact of the body(More)
The purpose of the study was (a) to assess the accuracy of the regression equations available in the literature to estimate the actual peak power (PPac) of the countermovement jump (CMJ) executed by young male soccer players, (b) to develop new regression equations from this population, and (c) to verify whether regression equations obtained from age-based(More)
Falls and loss of consciousness (FLoC) is the leading cause of serious health problems, above all in the elderly population, since the subjects involved are not able to ask for help and may lie in critical conditions for a long time, thus deteriorating into severe conditions which can even lead to death. Therefore, developing a device capable of(More)
In order to verify whether orthostatic posturography (OP) can support clinical assessment of total hip (THA) and knee arthroplasty (TKA), 81 subjects with THA and 100 with TKA were recruited and compared with 59 healthy volunteers. All patients were tested one or two days prior to surgery; 42 subjects (20 THA and 22 TKA) were tested again after six months,(More)
For preventing the onset of disorders of the upper extremity, in upholstered furniture workers, it was decided to monitor their handgrip applying a method previously developed to 262 volunteers recruited among upholstered furniture workers. At the test time, only 23 subjects had clinical symptoms referable to upper limb work-related musculoskeletal(More)
An investigation was started aimed at a better understanding of the complex phenomena leading to chemical degradation and morphological deterioration of UHMW polyethylene cups in total hip prostheses. Analysis was performed on retrieved implants which needed revision due to inflammation and pain problems. Preliminary results obtained by parallel XPS and(More)
BACKGROUND A number of different surgical procedures have been developed to treat Achilles tendon injuries including open and mini-invasive type. The aim of the present work was to compare the functional outcome of two different techniques, applying a clinical and instrumented protocol. MATERIALS AND METHODS Fifty-one subjects were enrolled in the study.(More)
