RESUMO
Background: Joint proprioception plays an important role in limb movement and awareness of position sense. Diabetes has a lot of complications such as loss of sensory function, which can lead to impaired balance, thus the aim of this study to evaluated joint proprioception and balance in diabetic patients
Methods: Twenty type II diabetic patients and 20 healthy controls participated in this case-controlled study. Standing balance in various positions and ankle joint proprioception were measured. The data were analyzed using Mann-Whitney and chi-square test
Results: It was observed that the ankle joint proprioception and balance in diabetic patients were significantly less than control groups. [P<0.05]
Conclusion: Joint proprioception and balance functions impair in diabetic patients. Thus improvement of joint proprioception for prevention of fall is important
RESUMO
Background: At the present time, massage has become a popular therapy employed in complementary medicine. There is evidence showing that back massage might have many positive psychological effects, possibly due to having many autonomic nervous system afferent inputs. One of the frequent positions during massage is prone position. However, there has been limited research investigating the effect of back massage in the prone position on blood pressure [BP] and heart rate [HR]. The present study planned to investigate the changes of blood pressure and heart rate after back massage in prone position
Methods: Sixty-one healthy women were divided into two groups. Group one lay prone and was given a 15-minute massage while group two just lay prone for 15 minutes. Immediately prior to and after interventions, systolic and diastolic blood pressure and heart rate were measured in both groups. To assess within group differences, paired t-test was used. Independent t-test was also used to assess between group differences
Results: The results showed that systolic blood pressure decreased significantly after massage and also in the group only lying prone [P<0.05], with no significant difference between groups [P>0.05]. Changes of diastolic blood pressure and heart rate were not significant in either group
Conclusion: Massage and lying prone both can cause a decrease in systolic blood pressure. Massage was not seen to be more efficient than lying prone
RESUMO
Background: Joint position sense [JPS] is comprised of sensory input from several sources, including skin, joint capsule/ligaments, and muscular receptors. If the muscle receptors play a leading role in detecting joint position awareness, then muscle fatigue might yield a declination in JPS. The aim of this study was to evaluate if a sustained fatiguing contraction of the tibialis anterior [ankle dorsiflexor] could alter the ankle JPS
Methods: This was a cross-sectional study in which 40 healthy subjects [age, 23.9 +/- 2.3 years; height, 172.6 +/- 5.7 cm; weight, 67.8 +/- 4.7 kg] were recruited. Subjects were asked to recognize 2 pre-recognized positions [10 degree in dorsiflexion [DF] and 21 degree in plantarflexion [PF]] for 2 experimental conditions: normal and fatigued. Muscular fatigue was induced in the tibialis anterior of the dominant leg by using an isometric test. The average of the absolute angular error [AAE] deviations from the target positions of three trials were recorded as scores for both fatigue and non-fatigue conditions
Results: There was significant decrease in subjects' abilities to recognize active and passive repositioning of their ankle after a fatigue protocol [P=0.0001]
Conclusion: The acuity of the ankle JPS is reduced subsequent to a fatigue protocol
