1. Nogueira Neto, Guilherme Nunes, 1978-. Viabilidade do emprego de mecanomiografia no controle motor artificial em lesados medulares empregando estimulação elétrica neuromuscular: Feasibility of MMG use in artificial motor control of spinal cord injured persons during neuromuscular electrical stimulation.

Degree: 2013, Universidade Estadual de Campinas

Abstract: Spinal cord injury affects conduction of motor and sensory signals that flow through the spinal cord. Therefore, the performance of voluntary movements by spinal cord injured (SCI) persons is impaired, if not impossible. Neuromuscular electrical stimulation (NMES) is a technique that aids SCI individuals to overcome these difficulties, because it allows activation of paralyzed limb muscles. Though NMES in open loop and in open chain tasks is able to generate movements in paralyzed limbs, it is not capable to automatically compensate for angle deviations due to disturbances. Suppressive phenomena of muscle performance, such as muscle fatigue and motor neuron adaptation, can compromise the quality of an artificially elicited functional moment. Thus, closed-loop control systems are merged with electrical stimulators. Mechanomyography (MMG) can provide information about a contracting muscle condition. This work proposes to investigate the feasibility of using MMG signals in the control of NMES application aiming its incorporation in lower limb control strategies of untrained spinal cord injured persons. An integrated system was built, comprising a multiparametric acquisition system and a closed-loop controlled neuromuscular electrical stimulator. The integrated system is able to incorporate MMG signals in the control strategy. A test with healthy volunteers performing upper limb isometric contractions indicated variations in MMG parameters between the beginning and end of contraction. Another test investigated MMG signals and joint angles with NMES in open loop and in open chain to healthy and SCI individuals. NMES and MMG signals during lower limb dynamic contractions were registered. Using the integrated system, NMES was applied to the control of knee angle in closed loop configuration ensuring angular stability of both knees on a single SCI volunteer. Finally, the integrated system applied closed loop control to stabilize the knee angle, and monitored MMG signals. Experimental results revealed that spectral parameters such as mean power frequency presented variations between the beginning and end of contraction when NMES amplitude showed higher amplitude increase rates. In conclusion, there is feasibility of using MMG signals in control strategies of NMES for lower limbs of SCI persons in reasonable angle stability. However, one must observe the stimulator output increase/decrease rate Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Button, Vera Lúcia da Silveira Nantes, 1959- (advisor), Nohama, Percy (coadvisor), Universidade Estadual de Campinas.

2. Nunes, Ligia Christina Borsato Guimarães. Tradução e validação de instrumentos de avaliação motora e de qualidade de vida em paralisia cerebral: Translation and validation of quality of life and motor evaluation tools in cerebral palsy.

Degree: 2008, Universidade Estadual de Campinas

Abstract: Systematized evaluation tools for children with Cerebral Palsy is very important in evaluation, treatment and research. The pediatrics Quality of Life Questionnaire PedsQL has the purpose of verify the diseases impact in quality of life. Its Cerebral Palsy version encompasses more specific questions regarding motor damage due to CP. The Gross Motor Function Measure GMFM) is a tool that aims to quantify Gross Motor Function. It is widely used around the world, including Brasil. Changes on the gait patterns are common in CP. The golden standard to evaluate gait is three-dimensional gait analysis, although it is not possible to perform this evaluation as a routine in clinics. The Edimburgh Visual Gait Scale was developed based on video. Although the importance of these tools is incontestable and some are being used in Brazil, there is no official translation, nor validation nor cultural adaptation of them. There is still a lack of intra and inter rater reliability studies of the three tools and the training effects on observational gait scales. The purposes of this work are to translate, validate and culturally adapt the above mentioned tools, to verify the correlation between the Edinburgh gait scale and 3D gait analysis as well as to study the training influence on inter and intrarater reliability and on agreement with golden standard. 64 parents and 36 children with CP took part of the PedsQL study; 10 children were filmed and evaluated trough the Brazilian version of GMFM and two English children undergone to laboratorial and video gait evaluation. Eight Physical Therapists evaluated the GMFM videos and 22 Physical Therapists evaluated the gait videos, according to the Edinburgh gait scale. The Brazilian versions of PedsQL (first and modified) show good internal consistency, sensitivity and, although the two brazilian versions returned different scores, they show an almost perfect correlation. Further investigation with more children of all functional classifications is needed. Regarding GMFM, the global inter rater reliability was substantial and the intrarater reliability was almost perfect, which makes the Brazilian scale feasible even without the manual. However, the reliability found on this work was smaller than works that used the GMFM manual, still not translated to Brazil. It was developed a training package to the Edinburgh Visual Gait Scale in a simple, easy handling and interactive CD, with versions in English and Portuguese. The Brazilian version of the Edinburgh Visual Gait Scale had substantial intra rater reliability and modest inter rater reliability. The mean agreement with 3D gait analysis was less than 50% for trained and untrained groups. Training with CD has improved intra and inter rater reliability as well as agreement with 3D analysis. Reliability studies with more volunteers as well as studies with the English version training package and other training approaches are needed. The three evaluation tools available now in Portuguese will contribute with more studies in Cerebral Palsy… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Fasolo Quevedo, Antonio Augusto, 1970- (advisor), Quevedo, Antonio Augusto Fasolo (advisor), Universidade Estadual de Campinas.
