[Purpose] The purpose of this study was to examine the association between muscle-strengthening exercises applied to the knee extensor muscles and the maintenance of standing balance in both, the anteroposterior and mediolateral directions in patients who had undergone total knee replacement. [Subjects and Methods] Thirty patients who underwent total knee replacement with bilateral artificial joints participated in this study. During the eight-week study period, the load on the knee extensors was gradually increased, and the standing balance ability was measured by differentiating the anteroposterior and mediolateral directions both, before and after the experimental period. [Results] In both, the anteroposterior and the mediolateral directions, there were statistically significant increases after the eight-week experiment, with a 29% increase in standing balance maintenance in the anteroposterior direction and a 22% increase in the mediolateral direction. [Conclusion] In patients who underwent bilateral total knee replacement, strengthening exercises applied to the knee extensor muscles with gradually increasing load positively affected standing balance in both anteroposterior and mediolateral directions.

Orthopaedic Surgery, Kyoto Karasuma Hospital, Kyoto, JPN.
Dropped head syndrome (DHS) is characterized by a correctable cervical kyphotic deformity due to weakened cervical paraspinal muscles. Currently, there is no established treatment for the condition. Sensory integration pertains to the processing, integrating, and organizing of sensory information from both the body and the environment.

Purpose: The study aimed to determine the test-retest, interrater, and minimum detectable change, concurrent and known-groups validity in older adults with mild cognitive impairment. Minimal detectable change values are the degree of change needed to exceed a measurement's error within a confidence limit.
Methods: A total of 46 older adults with mild cognitive impairment and 34 healthy controls were included.
The effectiveness of core stability exercises on functional outcomes in early subacute stroke recovery: a randomized controlled trial.

Background: The core is important in providing local strength and balance and is central to almost all kinetic chains of daily activities.
Objective: This study aimed to assess the effectiveness of additional Core Stability Exercises (CSE) to conventional physiotherapy (CP) versus CP alone to improve dynamic sitting balance, coordination, trunk function, and stepping (gait) as a primary outcome and functional sitting balance, postural control, standing balance and fall risk, lower limb spasticity, activities of daily living, degree of disability, and quality of life for early subacute stroke recovery.
Methods: A multicentre parallel, randomized, controlled, assessor-blinded trial was conducted.
Comprehensive analysis and risk assessment of fine road dust in Abbottabad city (Pakistan) with heavy traffic for potentially toxic elements.

Human activities have far-reaching impact on natural ecosystems, causing increasing disturbances and disruptions to the delicate balance of the environment. Poor land use planning, urbanization, infrastructure development, and unplanned tourism exacerbate contamination and degradation in tourist destinations, yet the pollution of potentially toxic elements (PTEs) in these environments remains inadequately explored. To address this issue, we investigated the concentrations of acid-digested PTEs in road dust in Abbottabad city (Pakistan) with heavy traffic.

In this scholarly investigation, the study focuses on scrutinizing the locomotion and control mechanisms governing a single-legged robot. The analysis encompasses the robot's movement dynamics pertaining to two primary objectives: executing jumps and sustaining equilibrium throughout successive jump sequences. Diverse concepts of this robot model have been scrutinized, leading to the introduction of a distinctive semi-active model devised for maintaining the robot's balance.
