1. Neurovestibular Compensation following Ototoxic Lesion and Labyrinthectomy
Abstract Introduction Unilateral labyrinthectomy and intra-tympanic gentamycin have been employed in the treatment of Ménière's disease, but the efficacy of these techniques has not been well established. Objective The objective of this study is to measure the time course of recovery from a unilateral labyrinthectomy either after ipsilateral topical tr

2. A new FEM procedure for transverse and longitudinal vibration analysis of thin rectangular plates subjected to a variable velocity moving load along an arbitrary trajectory
A combined plate element is presented for the analysis of transverse and longitudinal vibrations of a thin plate which carries a load moving along an arbitrary trajectory with variable velocity. Depending on the acceleration of the point load on its trajectory on the plate surface, the combined element, which is a combination of the 24 DOF plate element and

3. Análise clínica e funcional da espasticidade antes e após a estimulação elétrica neuromuscular e marcha em esteira com EENM em lesados medulares / Clinical and functional analysis of spasticity before and after neuromuscular electrical stimulation and treadmill gait with NMES in spinal cord injury
Spinal cord injury has as one of its consequences the spasticity, which is usually present in lesions above the last thoracic level (T12) and it can be assessed through quantitative and qualitative indicators. In the study it was evaluated two groups: Neuromuscular Electrical Stimulation (NMES) group with sixteen patients and the group of eight patients that

4. Análise da influência de um calçado flexível e desprovido de salto sobre a mecânica da marcha e a carga articular de indivíduos com osteoartrite de joelho / Influence of flexible footwear and without heel on the gait mechanics and joint loading in individuals with knee osteoarthritis
The literature has been given evidences that the use of flexible and non-heeled footwear that reproduces the kinematic and kinetic characteristics of barefoot gait may reduce the joint loads and the progression of the knee osteoarthritis (OA). The purpose of this study was to evaluate and compare the influence of the acute use of flexible, non-heeled and ine

5. Mecanização de central de navegação inercial com dados a partir da integração de IMU MEMS e receptor GPS / Inertial navigation mechanization through the intergration of an IMU MEMS and a GPS receiver.
The proposal of this work is to present a procedure for integration of the acceleration and angular rate measurements of a low cost Inertial Measurement Unit (IMU) based on MEMS (Micro Electro-Mechanical System) technology with position and speed data from a GPS receiver. Then, it details the equations that have been used to integrate the movement and the at

6. Fator-S astrofísico da reação de captura de próton 8Li(p,)9Be através do estudo da reação de transferência elástica 9Be(8Li,9Be) / Astrophysic S-Factor for the proton capture reaction 8Li(p,)9Be using the study of the elastic transfer reaction 9Be(8Li,9Be)
Esse trabalho consistiu na determinação do Fator-S astrofísico da reação de captura 8Li(p,)9Be através do estudo da reação de transferência elástica 9Be(8Li,9Be)8Li. O fator espectroscópico do estado ligado 8Li+p=9Be, obtido à partir das medidas da distribuição angular da reação de transferência 9Be(8Li,9Be)8Li, foi utilizado para normalizar

7. Techniques for the estimation of angular FRFs in modal testing with applications to beam type structures / Técnicas para estimativa de FRFS angulares em análise modal experimental com aplicações a estruturas do tipo viga
Este trabalho realiza uma investigação sobre técnicas experimentais para a determinação de Funções de Resposta em Freqüência (FRFs) angulares com aplicações em estruturas do tipo viga. Estas FRFs são definidas considerando-se como variável de saída o movimento angular (deslocamento, velocidade ou aceleração) exibido pela estrutura sob estudo

8. O controle dos movimentos voluntarios do ombro em nadadores com instabilidade glenoumeral
The Shoulder Impingement Syndrome (SIS) is often observed in repetitive movements of the shoulder above 60° during the performance of occupational or athletic activities. This dysfunction affects a great number of athletes, and in special 80% of the professional swimmers. In this population the glenohumeral instability is frequently associated with this syn

9. Convergence of excitatory and inhibitory hair cell transmitters shapes vestibular afferent responses
The vestibular semicircular canals respond to angular acceleration that is integrated to angular velocity by the biofluid mechanics of the canals and is the primary origin of afferent responses encoding velocity. Surprisingly, some afferents actually report angular acceleration. Our data indicate that hair-cell/afferent synapses introduce a mathematical deri

10. The contribution of otoliths and semicircular canals to the perception of two-dimensional passive whole-body motion in humans.
1. Perception of two-dimensional (2-D) whole-body passive motion in the horizontal plane was studied in twelve blindfolded healthy volunteers: pure rotation in place (180 deg), linear motion (4.5 m) and a semicircular trajectory (radius, 1.5 m; angular acceleration, 0.2 rad s-2) were applied in random sequence by means of a remote-controlled robot equipped w

11. Physiological analysis of simple rapid movements in patients with cerebellar deficits.
Patients with cerebellar deficits made elbow flexion movements as rapidly as possible for three different angular distances. Electromyographic activity of biceps and triceps and the kinematics of the movements were analysed. Results were compared with those of normal subjects making both rapid and slow movements. In the patients, the first agonist burst of t

12. Organization of motor output in slow finger movements in man.
1. Slow finger movements were analysed in normal human subjects with regard to kinematics and EMG activity of the long finger muscles. Surface EMG from the finger extensor and flexor muscles on the forearm was recorded along with angular position and angular velocity during voluntary ramp movements at single metacarpophalangeal joints. Angular acceleration w
