- Rehabilitation in patients with cerebellar ataxias(2022) CHIEN, Hsin Fen; ZONTA, Marise Bueno; CHEN, Janini; DIAFERIA, Giovana; VIANA, Celiana Figueiredo; TEIVE, Helio Afonso Ghizoni; PEDROSO, Jose Luiz; BARSOTTINI, Orlando Graziani PovoasCerebellar ataxias comprise a heterogeneous group of diseases characterized by motor and non-motor symptoms, which can be acquired, degenerative, or have a genetic cause, such as spinocerebellar ataxias (SCA). Usually, the genetic and neurodegenerative forms of cerebellar ataxias present a progressive and inevitable worsening of the clinical picture so that rehabilitation treatment is fundamental. Rehabilitation treatment includes physical therapy, respiratory therapy, speech, voice and swallowing therapy, occupational therapy, and new technologies, such as the use of exergames. The current treatment of patients with cerebellar ataxias, especially neurodegenerative forms, genetic or not, should include these different forms of rehabilitation, with the main objective of improving the quality of life of patients.
- Effects of resistance training on postural control in Parkinson's disease: a randomized controlled trial(2021) CHEN, Janini; CHIEN, Hsin Fen; FRANCATO, Debora Cristina Valente; BARBOSA, Alessandra Ferreira; SOUZA, Carolina de Oliveira; VOOS, Mariana Callil; GREVE, Julia Maria D'Andrea; BARBOSA, Egberto ReisBackground: Postural instability affects Parkinson's disease (PD) patients' postural control right from the early stages of the disease. The benefits of resistance training (RT) for balance and functional capacity have been described in the literature, but few studies have been conducted showing its effects on PD patients' postural control. Objective: To investigate the effects of a three-month RT intervention on static posturography (SP) measurements and clinical functional balance assessment among PD patients. Methods: Seventy-four patients were randomly assigned to a three-month RT intervention consisting of using weightlifting machines at a gym (gym group) or RT consisting of using free weights and elastic bands (freew group), or to a control group. The participants were evaluated at baseline, three months and six months. We evaluated changes of SP measurements under eyes-open, eyes-closed and dual-task conditions (primary endpoint), along with motor performance and balance effects by means of clinical scales, dynamic posturography and perceptions of quality of life (secondary endpoints). Results: There were no significant interactions in SP measurements among the groups. Unified Parkinson Disease Rating Scale (UPDRS-III) motor scores decreased in both RT groups (p<0.05). Better perceived quality of life for the mobility domain was reported in the gym group while functional balance scores improved in the freew group, which were maintained at the six-month follow-up (p<0.05). Conclusions: This study was not able to detect changes in SP measurements following a three-month RT intervention. Both RT groups of PD patients showed improved motor performance, with positive balance effects in the freew group and better perceived quality of life in the gym group.
- 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.
