Introduction: For diagnosing some of the hip diseases, it is important to obtain the hip's range of motion. For example loss of internal rotation in the hip is one of the first signs of internal hip pathology and can be related to diagnoses, such as arthritis. Also, increase in femoral or acetablular anteversion usually demonstrates an increase in the internal rotation. Clinical hip examination...

OBJECTIVE We conducted a laboratory-based calibration study to determine relevant cutpoints for a hip-worn accelerometer among women ≥60 years, considering both type and filtering of counts. METHODS Two hundred women wore an ActiGraph GT3X+ accelerometer on their hip while performing eight laboratory-based activities. Oxygen uptake was measured using an Oxycon portable calorimeter. Accelerome...

    Background: The aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3D reconstructive CT scan imaging. Methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. Preoperatively, all the patients underwent a CT scan according to a standard ...

A method for gait analysis using wearable acceleration sensors and gyro sensors is proposed in this work. The volunteers wore sensor units that included a tri-axis acceleration sensor and three single axis gyro sensors. The angular velocity data measured by the gyro sensors were used to estimate the translational acceleration in the gait analysis. The translational acceleration was then subtrac...

Background: The angle between femur neck and the long axis of shaft is known as which plays vital role in stability, control lateral balance, walking hip movements. main goal was to compare NSA intertrochanteric fracture immediately after surgical fixation using either Dynamic Hip Screw or Proximal Femoral Nail. In elderly among all fractures approximately half are out 50% unstable.Method: X-ra...

To determine the effect of plant leg and approach condition on the torques of the hip, knee, and ankle in soccer kicking tasks, nine female collegiate soccer players performed a series of kicking tasks from three different approach conditions. Kinematic data of the hip, knee, and ankle were recorded and joint torques of the plant leg were calculated. Peak flexor torque of the hip and ankle was ...

A total of 125 consecutive hip fracture patients were investigated regarding hip geometry. There were 33 men of mean age 76 +/- 10 years, and 92 women of mean age 78 +/- 9 years. Patients with previous hip surgery were excluded. Hip geometry (hip-axis length, width of collum femoris, and femoral shaft and neck-shaft angle) were registered on both plain radiographs and DEXA scans performed withi...

BACKGROUND The purpose of this study was to determine the relationships among hip geometry, bone mineral density, and the risk of hip fracture in premenopausal women. METHODS The participants in this case-control study were 16 premenopausal women with minimal-trauma hip fractures (fracture group) and 80 age-and BMI-adjusted controls. Subjects underwent dual-energy X-ray absorptiometry (DXA) t...

In Wearable Well-Being project PUHVI, HipGuard system for patients recovering from hip surgery was developed. Novel wireless sensors having 3-axis acceleration and 3-axis magnetic sensors are used to measure patient’s hip and leg position and rotation. Furthermore, capacitive insole sensors are used to measure the force between foot and a shoe. This paper concentrates on how these sensors can b...
