- Avaliação interdisciplinar da diadococinesia: um estudo piloto(2017) ALBUQUERQUE, Jessica Talita da Cruz; MACEDO, Tamara Passos; FAVERO, Francis Meire; BARBOSA, Alessandra Ferreira; CAROMANO, Fátima Aparecida; VOOS, Mariana CallilABSTRACT Diadochokinesis is the ability to perform fast, repeated and alternate movements. Diadochokinesis tests can assess both speech and upper extremities. The primary objective was to present an interdisciplinary diadochokinesis assessment protocol. The secondary objectives were to compare the performance with different phonemes of the oral diadochokinesis test (/papapa/, /tatata/, /kakaka/ and /pataka/); to compare the performance with different conditions of the upper extremities diadochokinesis test (conducted with both upper extremities in a mirrored manner, only with the right upper extremity, only with the left upper extremity, with both upper extremities in an alternately manner); and to investigate possible relationships between oral and upper extremities diadochokinesis. A total of fifteen healthy adults/seniors from 40 to 70 years old participated. Data were represented by descriptive statistics. The syllable numbers in /papapa/, /tatata/, /kakaka/ and /pataka/ conditions and the numbers of movements in mirrored, right, left and alternated conditions were compared by ANOVA and correlated by Pearson test. There was no significant difference in results between the phonemes of oral diadochokinesis test (p<0.001). There was difference between the conditions assessed in the upper extremities diadochokinesis test (p<0.001). The number of repeated phonemes was correlated with the alternate performance of upper extremities. We concluded that the correlation between scores of oral and upper extremities diadochokinesis tests can be explained by the fact that motor and language programs are predominantly represented in the left hemisphere. Common/connected brain areas or motor programs in common can guide these tasks.
- Gait, posture and cognition in Parkinson's disease(2016) BARBOSA, Alessandra Ferreira; CHEN, Janini; FREITAG, Fernanda; VALENTE, Debora; SOUZA, Carolina de Oliveira; VOOS, Mariana Callil; CHIEN, Hsin FenABSTRACT Gait disorders and postural instability are the leading causes of falls and disability in Parkinson's disease (PD). Cognition plays an important role in postural control and may interfere with gait and posture assessment and treatment. It is important to recognize gait, posture and balance dysfunctions by choosing proper assessment tools for PD. Patients at higher risk of falling must be referred for rehabilitation as early as possible, because antiparkinsonian drugs and surgery do not improve gait and posture in PD.
- Postural control in women with breast hypertrophy(2012) BARBOSA, Alessandra Ferreira; RAGGI, Gabriela Cristina; SA, Cristina dos Santos Cardoso; COSTA, Marcio Paulino; LIMA JR., Jonas Eraldo de; TANAKA, ClariceOBJECTIVES: The consequences of breast hypertrophy have been described based on the alteration of body mass distribution, leading to an impact on psychological and physical aspects. The principles of motor control suggest that breast hypertrophy can lead to sensorimotor alterations and the impairment of body balance due to postural misalignment. The aim of this study is to evaluate the postural control of women with breast hypertrophy under different sensory information conditions. METHOD: This cross-sectional study included 14 women with breast hypertrophy and 14 without breast hypertrophy, and the mean ages of the groups were 39 +/- 15 years and 39 +/- 16 years, respectively. A force platform was used to assess the sensory systems that contribute to postural control: somatosensory, visual and vestibular. Four postural conditions were sequentially tested: eyes open and fixed platform, eyes closed and fixed platform, eyes open and mobile platform, and eyes closed and mobile platform. The data were processed, and variables related to the center of pressure were analyzed for each condition. The Kruskal-Wallis test was used to compare the conditions between the groups for the area of center of pressure displacement and the velocity of center of pressure displacement in the anterior-posterior and medial-lateral directions. The alpha level error was set at 0.05. RESULTS: Women with breast hypertrophy presented an area that was significantly higher for three out of four conditions and a higher velocity of center of pressure displacement in the anterior-posterior direction under two conditions: eyes open and mobile platform and eyes closed and mobile platform. CONCLUSIONS: Women with breast hypertrophy have altered postural control, which was demonstrated by the higher area and velocity of center of pressure displacement.
- Cognitive or Cognitive-Motor Executive Function Tasks? Evaluating Verbal Fluency Measures in People with Parkinson's Disease(2017) BARBOSA, Alessandra Ferreira; VOOS, Mariana Callil; CHEN, Janini; FRANCATO, Debora Cristina Valente; SOUZA, Carolina de Oliveira; BARBOSA, Egberto Reis; CHIEN, Hsin Fen; MANSUR, Leticia LessaIntroduction. Executive function deficits are observed in people with Parkinson's disease (PD) from early stages and have great impact on daily living activities. Verbal fluency and oral diadochokinesia involve phonarticulatory coordination, response inhibition, and phonological processing and may also be affected in people with PD. This study aimed to describe the performance of PD patients and an age-and education-matched control group on executive function, verbal fluency, and oral diadochokinesia tests and to investigate possible relationships between them. Methods. Forty people with PD and forty controls were evaluated with Trail Making Test (TMT, executive function) and phonemic/semantic verbal fluency and oral diadochokinesia (/pataka/) tests. Groups were compared by ANOVA and relationships were investigated by Pearson tests. Results. People with PD showed longer times in parts A and B of TMT. They also said fewer words in phonemic/semantic verbal fluency tests and less syllables in the diadochokinesia test. Oral diadochokinesia strongly correlated to parts A and B of TMT and to phonemic verbal fluency. Conclusion. Oral diadochokinesia was correlated to executive function and verbal fluency. The cognitive-motor interaction in verbal fluency and oral diadochokinesia must be considered not to overestimate the cognitive or motor impairments in people with PD.
- Relationship Between Posturography, Clinical Balance and Executive Function in Parkinson ' s Disease(2019) SOUZA, Carolina de Oliveira; VOOS, Mariana Callil; BARBOSA, Alessandra Ferreira; CHEN, Janini; FRANCATO, Debora Cristina Valente; MILOSEVIC, Matija; POPOVIC, Milos; FONOFF, Erich Talamoni; CHIEN, Hsin Fen; BARBOSA, Egberto ReisThis study aimed to evaluate the relationship between posturography, clinical balance, and executive function tests in Parkinson ' s disease (PD). Seventy-one people participated in the study. Static posturography evaluated the center of pressure fluctuations in quiet standing and dynamic posturography assessed sit-to-stand, tandem walk, and step over an obstacle. Functional balance was evaluated by Berg Balance Scale, MiniBESTest, and Timed Up and Go test. Executive function was assessed by Trail Making Test (TMT) and semantic verbal fluency test. Step over obstacle measures (percentage of body weight transfer and movement time) were moderately correlated to Timed Up and Go, part B of TMT and semantic verbal fluency (r > 0.40; p < 0.05 in all relationships). Stepping over an obstacle assesses the responses to internal perturbations. Participants with shorter movement times and higher percentage of body weight transfer (higher lift up index) on this task were also faster in Timed Up and Go, part B of TMT, and semantic verbal fluency. All these tasks require executive function (problem solving, sequencing, shifting attention), which is affected by PD and contribute to postural assessment.
conferenceObject Executive function and verbal fluency in patients with Parkinson's disease(2016) BARBOSA, A. F.; VOOS, M. C.; SOUZA, C. O.; CHEN, J.; CHIEN, H. F.; FRANCATO, D. V.; BARBOSA, E. R.; MANSUR, L. L.- The competition with a concurrent cognitive task affects posturographic measures in patients with Parkinson disease(2015) BARBOSA, Alessandra Ferreira; SOUZA, Carolina de Oliveira; CHEN, Janini; FRANCATO, Debora Valente; CAROMANO, Fatima Aparecida; CHIEN, Hsin Fen; BARBOSA, Egberto Reis; GREVE, Julia Maria D'Andrea; VOOS, Mariana CallilObjectives: To estimate the impact of a sensory-motor-cognitive task on postural balance, in Parkinson disease patients (Hoehn and Yahr 2-3) and to investigate possible relationships between posturography and functional balance clinical scales. Method: Parkinson disease patients (n = 40) and healthy controls (n = 27) were evaluated with fluency tests, Berg Balance scale, Mini Best test and static posturography on the conditions eyes open, eyes closed and dual-task (simultaneous balance and fluency tasks). Results: Posturographic data showed that Parkinson disease patients performed worse than controls in all evaluations. In general, balance on dual-task was significantly poorer than balance with eyes closed. Posturographic data were weakly correlated to clinical balance scales. Conclusion: In clinical practice, Parkinson disease patients are commonly assessed with eyes closed, to sensitize balance. Our study showed that adding a cognitive task is even more effective. Static posturographic data should be carefully overgeneralized to infer functional balance impairments.
- Visual, cognitive and motor skills in children with type I spinal muscle atrophy(2015) VOOS, M.; POLIDO, G.; BARBOSA, A.; FAVERO, F.; CAROMANO, F.
- Matching pairs difficulty in children with spinal muscular atrophy type I(2017) POLIDO, Graziela Jorge; BARBOSA, Alessandra Ferreira; MORIMOTO, Carlos Hitoshi; CAROMANO, Fatima Aparecida; FAVERO, Francis Meire; ZANOTELI, Edmar; REED, Umbertina Conti; VOOS, Mariana CallilThis study aimed to investigate the performance on pair-matching tasks in children with Spinal Muscular Atrophy type I (SMA-I) and the relationship between this performance and motor function, functional independence and quality of life. SMA-I (n = 12; 6.0 +/- 2.3 yrs; 9 boys, 3 girls) and control sex-, age-matched children (n = 12; 6.2 +/- 2.6 yrs) performed four pair-matching figure, number and letter tasks. The eye tracker detected eye movements. SMA-I children were assessed with CHOP INTEND, Pediatric Evaluation of Disability Inventory, and Pediatric Quality of Life Inventory. Analysis of variance showed that SMA-I children had a lower percentage of correct answers and longer timed performance compared to controls (p < 0.05). Pediatric Evaluation of Disability Inventory score (social function domain) was correlated to the percentage of correct answers on the pair-matching tasks on task 1 (r = 0.81; p = 0.001) and task 2 (r = 0.66; p = 0.020). Pair-matching performance of SMA-I children was poorer than the performance of control children. There was a relationship between pair-matching performance and social function. The restricted interaction with the environment, due to severe paralysis and poor verbal communication, is associated with cognitive difficulties in SMA-I children. The eye tracker was helpful in cognitive assessment of SMA-I children, who responded to the cognitive tests with eye movements.
