Nach dem Hüftbruch: Welche Schrittzahlen auf eine gute Erholung hindeuten

<b>Background</b>: Step count has emerged as an objective indicator of physical activity, yet its association with functional recovery following hip fracture remains unclear. <b>Objective</b>: This study aimed to evaluate daily step counts after hospital discharge in older adults with hip fracture and to determine thresholds associated with functional improvement. <b>Methods</b>: A prospective, observational study was conducted in patients aged over 75 years admitted with hip fracture. Daily steps were recorded using validated activity trackers. Functional status was assessed at one, three, and six months after discharge through telephone interviews. Functional improvement was defined as an increase of at least 5 points on the Barthel Index. Step count thresholds were estimated using Liu's method based on receiver operating characteristic (ROC) analysis. <b>Results</b>: Ninety-four patients were included with a mean age of 83.2 ± 6 years, with 80.8% being female. Of the patients included in the study who recorded their daily steps after hip surgery, 59 patients (72%) improved during the first month after discharge with a median of 220 daily steps (IQR: 103.5-494.5; cut-off point at 150 steps). At the third month after hip fracture, 77 patients (86.5%) showed functional improvement with a median of 778 steps (IQR: 263-1697; cut-off point at 425 steps). At month six, 65 patients (80.2%) showed functional improvement with a median of 1757 steps (IQR: 696-3388; cut-off point at 2

<h4>Background</h4>Physical activity has been reported to be associated with surgical outcomes, but most previous studies have focused solely on postoperative step counts. To better understand the relationship between step count at different phases and surgical outcomes, we prospectively recorded patients' step counts before and after lung surgery.<h4>Methods</h4>Step count data were collected from 244 patients who underwent minimally invasive surgery for lung cancer using Mi Band 5 to track preoperative and 3-day postoperative activity. Patients' quality of life was assessed using the 12-Item Short Form Health Survey (SF-12) preoperatively and at 1 and 3 months postoperatively. Correlation and regression analyses were conducted to evaluate the impact of perioperative step count on hospital length of stay and quality of life.<h4>Results</h4>Preoperative (<i>r</i> = -0.146, <i>p</i> = 0.023) and postoperative day 1 (<i>r</i> = -0.172, <i>p</i> = 0.018) step count were significantly correlated with the length of hospital stay. Postoperative day 1 step count was positively correlated with changes in SF-12 Physical Component Score (PCS) at 1 month (<i>r</i> = 0.186, <i>p</i> = 0.013). Pain significantly affected PCS changes at both 1 (<i>β</i> = -3.33, <i>p</i> < 0.001) and 3 months (<i>β</i> = -3.06, <i>p</i> < 0.001).<h4>Conclusion</h4>Higher preoperative step counts are associated with a shorter hospital stay, while early postoperative physical activity is linked to both reduc
