“…Third, no long-term follow-up measurements were recorded. Most of the patients with THA are discharged within 3-4 weeks postoperatively, and the greatest amount of functional improvement after THA is observed within 6 months postoperatively [ 16 , 17 , 27 ]. Therefore, the final measurement in our study was performed at 7 months postoperatively.…”

“…Leg muscle strength on the operated and nonoperated sides was measured using a hand-held dynamometer (HHD, Anima Co., μ -TasF1, Japan) during isometric contraction for 3 s with manual resistance. The HHD is a widely used, reliable, and valid instrument for measuring isometric peak force in studies of elderly patients or THA [ 6 , 16 , 17 ]. Positions chosen for testing were based on the previous literature [ 18 – 20 ] and considered patient safety for adherence to postoperative precautions after THA.…”

The aims of this study were to identify the preoperative factors influencing ambulation ability at different postoperative time points after total hip arthroplasty (THA) and to examine the cutoff values of predictive preoperative factors by receiver operating characteristic (ROC) curves. Forty-eight women with unilateral THA were measured for hip extensor, hip abductor, and knee extensor muscle strength in both legs; hip pain (visual analog scale, VAS); and the Timed Up and Go (TUG) test pre- and postoperatively. Multiple regression analysis indicated that preoperative knee extensor strength (β = −0.379, R 2 = 0.409) at 3 weeks, hip abductor strength (β = −0.572, R 2 = 0.570) at 4 months, and age (β = 0.758, R 2 = 0.561) at 7 months were strongly associated with postoperative ambulation, measured using the TUG test. Optimal preoperative cutoff values for ambulation ability were 0.56 Nm/kg for knee extensor strength, 0.24 Nm/kg for hip abductor strength, and 73 years of age. Our results suggest that preoperative factors predicting ambulation ability vary by postoperative time point. Preoperative knee extensor strength, hip abductor strength, and age were useful predictors of ambulation ability at the early, middle, and late time points, respectively, after THA.

“…However, crossing the legs may cause rotation of the pelvis 11 ) , thereby causing problems in the lumbar region. Studies report that lateral pelvic tilt might result when the hip abductors are weakened 12 ) . When sitting with the legs crossed, one leg is placed over the supporting leg, and the leg placed on top is in a state of abduction.…”

[Purpose] The purpose of this study was to identify postural changes in adults who have adopted the habit of sitting with their legs crossed. [Subjects and Methods] The subjects were 232 adults in their 20s and 30s (84 males and 148 females). They were divided into 0-, 1-, 2-, and 3-hour or more groups by observing how much time per day they sat with their legs crossed while sitting on a chair. We measured the postural alignment of all the subjects in the sagittal plane and coronal plane. In the sagittal plane, distances from the line of gravity to the external auditory meatus, the shoulder joints, the knee joints, and the calcaneocuboid joint were measured. In the coronal plane, the shoulder inclination and the pelvic tilt were measured. [Results] The shoulder joints, the knee joints, and the calcaneocuboid joint did not show any significant differences, but the head was aligned further forward in the 3-hour group compared to the other groups. In the coronal plane, the acromion processes and the anterior superior iliac spines of the 3-hour group showed statistically significant differences than those of all of the other groups. [Conclusion] The results indicate that sitting with the legs crossed for longer than three hours per day may cause shoulder inclination, lateral pelvic tilt and forward head posture.
