1) Widespread cinematic impairment was the rule in the studied population. 2) These findings are consistent with poor skeletal muscle performance, high metabolic expenditure and constant physical exhaustion. 3) Attention should be paid not only to the metabolic management but also to the physical rehabilitation required in cases of advanced obesity.

RESUMOIndivíduos com dor lombar têm redução na força e na resistência dos músculos paraespinhais. A avaliação da fadiga e da resistência dos músculos paraespinhais é importante, uma vez que tem sido reportado que indivíduos com lombalgia desenvolvem um déficit no condicionamento físico que influencia na força e na função do tronco. Além disso, ainda é incerto a relação da fadiga dos paraespinhais e o ângulo de flexão anterior de tronco. Os objetivos deste estudo foram comparar a fadiga em indivíduos com e sem dor lombar e correlacionar a fadiga com o ângulo de flexão anterior de tronco. O grupo lombalgia foi composto por dez indivíduos com diagnóstico médico exclusivo de lombalgia. O grupo controle foi composto por dez indivíduos que possuíam características físicas semelhantes. Inicialmente avaliou-se a flexão anterior de tronco dos indivíduos pelo método angular de Whistance. A fadiga dos músculos paraespinhais foi avaliada nas alturas de L1 e L5 por meio da eletromiografia de superfície em duas cargas: 50 e 75% da contração isométrica voluntária máxima. Os resultados do estudo indicaram que o grupo lombalgia apresentou menor força durante os testes de contração isométrica voluntária máxima (P < 0,004). Embora o grupo lombalgia tenha apresentado maior valor de fadiga, não houve diferença estatisticamente significante entre os dois grupos para as alturas de L1 e L5 nas duas cargas. As correlações entre a fadiga e o ângulo de flexão anterior de tronco mostraram-se de fracas a moderadas (valores entre r = -0,58 a 0,51). Estes achados indicam que ambos os grupos fadigam, entretanto o grupo lombalgia apresentou maior fadiga. Além disso, não se pode predizer a fadiga por meio do ângulo de flexão anterior de tronco.Palavras-chave: eletromiografia, análise espectral, fadiga, dor lombar. ABSTRACTSubjects with low back pain have reduction in strength and endurance of the erector spinae muscles. The assessment of the fatigue and the endurance of these muscles is important, once it has been reported that individuals with low back pain develop a deficit in physical conditioning which influences on trunk strength and function. Moreover, the relationship between back muscles fatigue and trunk forward flexion is still unclear. The aims of this study were to compare fatigue between individuals with and without low back pain and to correlate the muscles fatigue with the angle of trunk forward flexion. The low back pain group consisted of ten low back pain subjects. The control group was composed by ten subjects with similar physical characteristics and without low back pain. Initially, the trunk forward flexion was evaluated with the Whistance angular method. The erector spinae fatigue was assessed at L1 and L5 by surface electromyography on two loads: 50 and 75% of maximal voluntary isometric contraction. The results indicated that the low back pain group presented a lower strength output during maximal voluntary isometric contraction (P < 0.004). Although the low back pain group has presented greater values of fatigue, there ...

Introduction:The dual tasks (DT) is learned during the whole life and a prerequisite in functional performance in different activities of daily living. Healthy elderly have reduced ability to perform motor activities and cognitive tasks simultaneously, compared to young adults. Parkinson's disease (PD) is the second most common neurodegenerative disease in the elderly and classic motor symptoms coexist with prejudice in cognitive domains. Objective: To compare balance, gait and performance in dual tasks of individuals with

Objective: This study sought to understand which items are essential to the wheelchair from the perspective of a person with quadriplegic spinal cord injury (SCI). Method: The study was qualitative with semi-structured interviews and discourse analysis, as well as a checklist of the wheelchair being used and the wheelchair provided by the government's Unified Health System (SUS). Results: The causes of SCI were motor vehicle accidents (60%), diving into shallow waters (30%) and being struck by a vehicle (10%), respectively and the injury time averaged 16.3 years (± 7.14). All of the subjects were in physiotherapy. The number of wheelchairs tested before finding the proper one were two to five and some participants practiced adapted sports with the wheelchair. The checklist showed that the government wheelchair had insufficient items and the discourse analysis resulted in four categories: Items, materials, and conditions; Learning functionality; Advantages and disadvantages of the wheelchair; and Feelings experienced. The wheelchair is essential to acquiring mobility for people with quadriplegia and trying out different models and getting orientation on the items are important for their acquisition. Suitable items facilitate acceptance, better adaptation, mobility and enable autonomy. Conclusion: The wheelchair from the government's health system was insufficient, leading to its being abandoned, and wheelchairs acquired for their functionality, with essential items, responsive to the user's individuality and taste proved to be useful and appropriate, despite their high cost.
