Walking ability and activity level after hip fracture in the elderly--a follow-up.

The purpose of this study was to investigate which variables can predict walking ability and activity level 1 year after hip fracture and to describe changes over time regarding functional capacity. One hundred and fifty-seven patients (111 women, 46 men), mean age 80.9 (SD 9.5) years, operated on for hip fracture, and able to participate either fully or to some extent in performance tests approximately 1 week after operation were included. Due to high mortality and fragility, only 57 patients participated in the 1-year follow-up. The patients were tested at discharge regarding physical performance, pain and bone mineral density. Status before fracture was evaluated by means of interview. At the 1-year follow-up, patients were also asked about their activities outside the home. A stepwise logistic regression was used for prediction. The patients had a significantly faster walking speed and better balance function after 1 year than before. The test "Timed up and go" was a strong predictor for both walking ability and activity level 1 year after hip fracture. Knowledge about the patient's walking habits outdoors before hip fracture and the degree of independent walking before hip fracture strengthened the prediction.
