Many clinical studies have been developed assessment tools and measurements for clinical staff to provide balanced assessment and intervention. However, the factors of affecting postural control are diverse and complex, not all tools or measurement could effectively detect a risk of falling. In daily living, the postural control involved integration of sensation, biofeedback, movement response, and kinesthetic sense to maintain postural stability, and finally integrated into the neuromuscular system and coordination to help achieve the perfect postural control. Current clinical tools used to assess the fall or research methods to detect the incidence of falls and the lack of effective relevant and contradictory, and it's difficult to effectively evaluate the risk of falls (Gates, et al, 2008).
