Among the most common injuries during swimming are shoulder and back injuries due to poor technique. This is a consequence of the amount of force applied to the shoulder joint in order to be capable ...of dragging the whole arm outside the water and an exaggerated undulation motion of the body when submerging of bringing oneself up to start another arm stroke. The purpose of this prototype is to register, analyze and visualize X and Y angles with reference to the gravitational pull in the following body segments: forearm, arm, breast and lower back. With this it is possible to generate a reference with which injuries can be prevented during swimming. This prototype a motion analysis protocol by means of sensors that record in real time and suggest changes to avoid injuries, portable, compact and low-cost design with acceptable results.

Nebulized 3% hypertonic saline solution (HSS 3%) has proven to reduce hospital stay in infants with acute bronchiolitis, as compared with nebulized physiological saline solutions. There are no ...studies assessing the effectiveness of nebulized epinephrine in patients treated with HSS 3%. The aim of this study was to compare the length of stay (LOS) in hospitalized patients treated with HSS 3% with placebo vs. HSS 3% with epinephrine. Secondarily we aimed to assess the effectiveness and safety of both treatments.
We performed a prospective, randomized, double-blind, parallel-group study, including infants hospitalized for moderate acute bronchiolitis. Both groups received standard life support and were randomly treated with nebulized HSS 3% (7 mL) with either placebo 3 mL or epinephrine 3 mL. Nebulizations were initially administered every four hours and this interval was modified according to the patient's response.
Sixty-four infants were included, 32 patients in each group. No statistically significant differences were found between the two groups (P=0.948) in length of stay, disease severity, SatO2, respiratory rate or heart rate. On the third day of hospitalization, severity and respiratory rate in the HSS 3%+E presented a non statistically significant trend to an earlier improvement, (P=0.063 and P=0.096 repectively). No adverse events occurred. Four patients (two from each group) required transfer to the pediatric intensive care unit.
With a third of the final estimated sample, we find a trend to an earlier clinical recovery in the epinephrine group, even though no statistical significant differences in LOS were found. The study needs to be continued until the total sample is recruited.
Chronic Obstructive Pulmonary Disease (COPD) is a condition which requires, among others, the administration of bronchodilators and anti-inflammatory drugs to control the disease. They help to keep ...the airways clear and prevent the buildup of fluid and mucus. Inhalation is the most widely used form of administrating the medication because of its local and rapid action which normally is done by aerosol therapy. The objective of this study is to evaluate the effectiveness of two aerosol methods in clearing the airways of COPD patients, admitted with an exacerbation due to their disease. It also aims to evaluate its effects on the length of stay, oxygen saturation, dyspnea, autonomy and complications.
Randomized clinical trial. Traditional method (control group) and positive expiratory vibrating device (intervention group): two ways to deliver aerosol were compared. The following outcome variables were considered: length of stay, days of fever, oxygen saturation, need for NIV or VM, the basic activities of daily living index autonomy (Barthel), dyspnea (Borg scale) and peak-flow.
39 patients were included. Regarding hospital stay, patients in the intervention group spend an average of one day less in hospital. Also in this group there were fewer readmissions. No statistically significant differences were found in the remaining variables.
The inhalation treatment with a vibrating device with positive exhalation, appears to reduce the length of stay and prevent readmissions. It is important to continue research on non-pharmacological interventions as to achieve the prevention of relapses.
