Objective: To compare outcomes in octogenarians with younger patients up to 1 year after undergoing dynamic hip screw fixation for intertrochanteric fractures to see the effectiveness of the implant.
Methods: The retrospective case-control study was conducted at The Aga Khan University and comprised records of patients who underwent dynamic hip screw surgery between January 1, 2010, and December 31, 2012. They were divided into two groups based on their age:. Group A <80 years; and Group B > 80 years. All patients had a one-year follow-up> Data including mortality, morbidity, radiological healing time, postoperative ambulatory status and Harris hip score were recorded.
Results: Of the 150 patients, 114(76%) were in Group A and 36(24%) were in Group B. Up to 25(70%) of octagenarians dropped their ambulatory ability by one or two levels, whereas 107(94%) of Group A patients were able to either maintain their pre-injury ambulatory ability or dropped their ambulation by one level only (p=0.02). Postoperative complications were higher in Group B 9(25%) compared to Group A 4(4%). One-year mortality was also significantly higher in Group B 8(22%) compared to Group A 9(8%) (p=0.03).
Conclusions: Octagenarians undergoing internal fixation with dynamic hip screw had higher frequency of complications and death compared to younger patients.

This study evaluated the validity and reliability of the TecnoBody D-Wall system in assessing joint range of motion (ROM) during overhead squat movements in healthy individuals, using Kinovea as a reference tool for data comparison. A total of 29 participants (16 males, 13 females) with a mean age of 28.41 ± 6.

Background: We aimed to synthesize the kinematics and kinetics during landing and walking/running tasks of ankle copers compared with patients with chronic ankle instability and controls.
Methods: We systematically searched PubMed, CINAHL, SPORTDiscus, and Web of Science. Tri-planar lower extremity biomechanics (joint angle and moment at maximum and initial contact, and joint displacement) were synthesized using standard mean difference and 95 % confidence intervals.

Background: The degenerative spondylosis can cause the difficulty in maintaining sagittal and coronal alignment of spine, and X-ray parameters are the gold standard to analyze the malalignment. This study aimed to develop a new 3D full body scanner to analyze the spinal balance and compare it to X-ray parameters.
Methods: Ninety-seven adult participants who suffer degenerative spondylosis underwent 3D full body scanning, whole spine X-rays, clinical questionnaires and body composition analyses.

Department of Mechanical Engineering, Sogang University, 35 Baekbeom-ro, Mapo-gu, Seoul, 04107, Republic of Korea.
Background: Knee valgus loading is thought to be an important contributor to noncontact anterior cruciate ligament (ACL) injuries, but the effects of training programs focusing on decreasing knee valgus loading on lower extremity biomechanics with respect to ACL injury risk remain unclear. Thus, this study aimed to examine the effect of strength training designed to strengthen the medial thigh muscles on lower extremity joint kinematics, kinetics and muscle activity during single-leg landing.
Methods: A total of 35 healthy participants randomly conducted either exercises targeting medial thigh muscles (intervention group) or exercises that did not target specific lower extremity muscles (control group).

Department of Biomechanics and Center for Research in Human Movement Variability, University of Nebraska at Omaha, Omaha, NE 68182, USA; Department of Surgery and Research Service, Nebraska-Western Iowa Veterans Affairs Medical Center, Omaha, NE 68105, USA. Electronic address:
Background: This study leverages Artificial Neural Networks (ANNs) to predict lower limb joint moments and electromyography (EMG) signals from Ground Reaction Forces (GRF), providing a novel perspective on human gait analysis. This approach aims to enhance the accessibility and affordability of biomechanical assessments using GRF data, thus eliminating the need for costly motion capture systems.
Research Question: Can ANNs use GRF data to accurately predict joint moments in the lower limbs and EMG signals?
Methods: We employed ANNs to analyze GRF data and to use them to predict joint moments (363-trials; 4-datasets) and EMG signals (63-trials; 2-datasets).
