A randomized controlled trial of rehabilitation after hospitalization in frail older women: effects on strength, balance and mobility.
When frail older people become acutely ill , they are at increased risk of further functional deterioration and rehabilitation is needed to restore functioning . The effects of an out-patient multicomponent training program including strength training after hospitalization were studied in a r and omized controlled trial . Sixty-eight women ( mean age 83.0 + /- 3.9 years ) who were hospitalized due to an acute illness and were mobility impaired at admission were r and omized into training ( N = 34 ) and home exercise ( N = 34 ) groups . Maximal voluntary isometric strength of knee extension and hip abduction , dynamic balance , and maximal walking speed were measured before and after the 10-week training period , and 3 and 9 months after the end of the intervention . After the intervention , significant improvements were observed in the training group compared to the home exercise group in the maximal voluntary isometric knee extension strength ( 20.8 % vs. 5.1 % , P= 0.009 ) , balance scale ( + 4.4 points vs. -1.3 points , P= 0.001 ) and walking speed ( + 0.12 m s-1 vs. -0.05 m s-1 , P= 0.022 ) . Effects on knee extension and hip abduction strength , balance and walking speed were observed 3 months later , and some effects on hip abduction strength ( 9.0 % vs. -11.8 % , P= 0.004 ) and mobility were still apparent even 9 months after the intervention
Serious adverse events were rare , and no serious events were reported to be directly related to the exercise programme .
