Abstract
In Thailand, the number of elderly trends to rapidly increase. Advancing age induces decrement of many body systems which impact on the physical performances. Currently, people behaviors truly change in which it may be a reason of increase the prevalence of overweight and obesity in Thai elderly. Previous studies reported that body mass index (BMI) was closely related to endurance performance in elderly. However, cut-off point of BMI for determining endurance impairment is unknown. Thus, the study investigated cut-off point of BMI for determining eudurance impairment in 194 community-dwelling elderly. The participants were interviewed their characteristics and health information including age, gender, smoking status, drinking status, and underlying disease. Then, they were assessed their endurance performance using the 6-minute walk test (6MWT). The findings reported that a cut-off point of BMI to indicate endurance impairment was 23.0 kg/m2 (64.62% sensitivity, 46.51% specificity, area under the curve=0.5643). Furthermore, the findings showed a correlation of BMI and 6MWT (r = -0.24, p-value=0.001). Age, gender, smoking status, drinking status, and underlying disease also related to endurance ability (r = -0.159to -0.334, p-value<0.05). Although there was a low correlation between BMI and 6MWT, it was a significant trend of health promotion. Furthermore, other factors should also be concerned for planning an appropriate management in order to increase endurance performance to be independently perform activities in daily living of the elderly.

Abstract
Hyper-extended knee is described as knee pain associated with impaired knee extensor mechanism. Additionally, hyper-extension of knee may have reduced knee joint position sense that may reduce the individual`s ability to control end range knee extension movement. The Purpose of this study is to investigate the effects of visual bio-feedback information for plantar weight bearing distribution to plantar pressure for the foot, lower extremity muscle activities, and knee joint angle in subject with hyper-extended knee. Thirty subjects with hyper-extended knee were participated in the study. Surface electromyography were recorded for the rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius muscle activities. The plantar weight bearing distribution displayed and measured using a pressure measurement mats. Kinematic parameter for knee joint angle were recorded using a motion analysis system. A paired t-test was used to determine the significance between visual bio-feedback and prefer condition. Knee joint angle significantly decreased in the visual bio-feedback condition than prefer condition (p<0.05). RF and GCM muscle activities were significantly differ between visual bio-feedback and prefer condition (p<0.05). The results of this study showed that the visual bio-feedback information of plantar weight bearing distribution is effective for correction of hyper-extended knee.
