EFFECT OF BALANCE EXERCISE BALANCE AND MUSCLE STRENGTH AGAINST ELDERLY WITH RISK OF FALLING IN PUSKESMAS SUBDISTRICT KOLANG CENTRAL TAPANULI
Total growth of elderly population in the world is increasing, the results of a study published by the United Nations Population Fund - United revealing the number of elderly in the world can reach the amount of 1 billion people within the next 10 years. Predictions for 2020 are approximately 28.8 million people or about 11:34% of the total population (Sutriyanto, 2012). Prasansuk, (2004) also concluded that one advantage or influence balannce exercise is to improve postural balance the elderly. Aristo research results Farabi (2007) conducted at Hospital Dr. Kariadi that is not found patient falls with TUG test time of less than 10 seconds. A significant association between TUG test time with the frequency of falls (p <0.05). This research is a quantitative research design is quasi-experimental design with two-group pretest-posttest control group design. Statistical test in this research use test Independent t test to see differences in balance and muscle strength before and after the intervention in the control group and the intervention group. Paired samples test to test the level of significance of the effect of exercise on the balance balance and muscle strength in the elderly with fall risk sub-district Puskesmas Kolang Central Tapanuli and eta squared values to assess the effect size. squared = 0.51), with p = 0.003. This indicates a balance effect of exercise on the balance. The decline of the musculoskeletal system of the elderly have a very big role to teterjadinya falls on or it can be said that the factors decrease musculoskeletal system is purely belongs elderly who have an influence on postural balance. Terjdadi muscle wasting in the elderly causes decreased muscle strength, especially the muscles of the lower extremities. Eksterimitas muscle weakness below can cause postural balance disorders. This may result in inaction move, in short steps, decrease the rhythm, the foot can not tread firmly and tend to look shaky, difficult or delayed mengantisispasi outages like slipping and tripping. Some of these indicators can increase the risk of falls in the elderly (Darmojo 2011).
