- 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.
- 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.
- Is virtual reality beneficial for dual-task gait training in patients with Parkinson's disease? A systematic review(2019) FREITAG, Fernanda; BRUCKI, Sonia Maria Dozzi; BARBOSA, Alessandra Ferreira; CHEN, Janini; SOUZA, Carolina de Oliveira; VALENTE, Débora Francato; CHIEN, Hsin Fen; BEDESCHI, Cynthia; VOOS, Mariana CallilABSTRACT This systematic review examined the evidence about the effects of virtual reality (VR) on dual-task gait training in Parkinson's disease (PD). Methods: this study (PROSPERO registration CRD42019114736) aimed to answer the question: “Is VR beneficial for dual-task gait training in patients with PD?” We searched for studies from 2008 to 2018 on Medline/PubMed and Web of Science/Web of knowledge databases. The keywords were Parkinson AND gait training AND virtual reality OR Parkinson AND gait training AND game. A total of 55 articles were retrieved, of which 11 systematic reviews, 11 opinions, letters to the editor, posters or conferences abstracts and 17 studies not evaluating the effects of VR gait training were excluded. Three further studies addressing VR dual-task gait training in PD (found in references of studies selected) were also included. Therefore, 19 studies were included and analysed. Results: all studies reported gait improvement after VR training. Many clinical scales were used, hampering comparison of the effects of each protocol. Conclusion: VR dual-task gait training should be part of rehabilitation protocols for PD. The studies showed that VR training was effective, although specific guidelines have not yet been established.
