RESUMO
OBJECTIVES: Limitations of functional capacity and balance are common features of the natural history of spinocerebellar ataxias (SCA). However, their onset and progression patterns differ according to subtype. The aim of our study was to compare physical functionality and balance parameters in SCA10 and SCA3 patients, correlating with clinical variables. MATERIALS & METHODS: Cross-sectional study evaluating ninety-five SCA patients (60 with SCA3 and 35 with SCA10) with validated scales for functional independence, balance and the severity of signs and symptoms. RESULTS: The groups were similar in terms of age and gender, and results were adjusted for age at symptom onset. The SCA10 patients had better results for balance and functional independence (p < 0.007). They also had lower scores for disease severity (p < 0.0002) and the subitems gait (p < 0.0005), posture (p < 0.0021) and sitting balance (p < 0.0008). Symptom progression in both groups was similar for patients with a disease duration of up to ten years, but there was a more marked decline in SCA3 patients after this period. CONCLUSIONS: We have shown that disease progression as assessed by balance and physical functioning is slower in SCA10 patients than SCA3 patients, particularly after 10 years of disease. These findings are important as they can help to characterize the disease, assisting in the development of new therapies and rehabilitation programs.

The Swimming has numerous benefits in the physiological, psychological, social and cognitive aspects for the person with spinal cord injury. However, the process of learning the swim must be done in order to take advantage of the potential and the motor functions of the swimmer, through the planning of actions and teaching strategies that seek an effective swim with the fewest adaptations possible and respecting the specific conditions of the lesion. The objective was to verify how the teacher evaluates the motor function of the swimmer with the SCI and to understand how this instructional process acts in the learning of swimming through the perspective of the teacher. Methods: Participated in the research, twelve Physical Education teachers, who work with spinal cord injury swimmers. Data were collected through semi-structured interviews and a field diary. Results: The results demonstrated that, depending on the teaching style adopted by the teacher, he does not consider the student's feedback and perception. He acts only on the results and possibilities he sees. Therefore, in the teacher's view, the adaptability of the swimming technique is conditioned to the motor limitation of the individual with SCI, or according to the teacher's perspective on the functionality. Conclusion: We conclude that the use of strategies based on the traditional swimming technique showed that there is little awareness or lack of knowledge about the work of promoting the swimmer's motor function, confirmed to the extent that the contribution of the specific literature is incipient and does not satisfy the teacher's desire for knowledge.(AU)
