Abstract<\/strong><\/p>\n

Postural instability and falls are a major health concern associated with increasing age. Injuries and fractures are common consequences of these falls. Annually more than one thousand individuals in the capital area in Iceland seek the Emergency department at Landsp\u00edtali, following a fall and are diagnosed with a fracture. The aim of the doctoral thesis was to evaluate the effects of a new multi-sensory balance training program, among unsteady older adults as well as middle aged and elderly people with wrist fractures. Additionally, to explore the characteristics of the people with a wrist fracture. Three scientific peer reviewed papers are included in the thesis.<\/p>\n

The results revealed that the multi-sensory balance training increased postural control, walking speed, lower limb muscle strength and confidence during daily activities among the old unsteady individuals. The results also suggest that the multi-sensory balance training can reduce the rate of falls among older unsteady people. The multi-sensory balance training improved postural control among middle aged and elderly people with a wrist fracture, especially those with balance scores below age related norms prior to training.<\/p>\n

The results revealed that middle aged and old people with a wrist fracture, had developed various factors that are known to increase fall risk. Among those were reduced sensation in the feet, asymmetric vestibular function and reduced lower limb muscle strength. A wrist fracture has been reported to be a strong predictor of future fracture risk, among those hip fractures. A hip fracture can lead to reduced quality of life, increased health cost and even death. Predictive and preventive measures are therefore important to prevent future falls and fractures. The results of this research indicate factors that are worth to observe in the evaluation and treatment of people who have sustained a wrist fracture.<\/p>\n
