AI Article Synopsis
- The study investigates how aging affects balance, sensory integration, and lower limb strength in three groups of older adults.
- Eighty-one healthy older participants were divided into three age groups (60-69, 70-79, and ≥80 years) and assessed using various tests to measure their postural control and strength.
- Results showed that older individuals had greater amplitude displacement in balance tests and worse performance in strength tests, indicating that declines in lower limb strength contribute to postural control impairments, rather than changes in sensory integration.
Article Abstract
Introduction: The aging process leads to functional decline of sensorial organs, muscle mass and strength, as well as the sensorimotor integration, culminating in age-associated postural control impairments. The purpose of this study was to compare the balance, the sensorial integration process and the lower limb strength among three old aged groups.
Methods: Eighty-one community-dwelling healthy old people (58% women), assigned into three age groups [60-69 years (n=30), 70-79 years (n=40), and ≥80 years (n=11)], participated in this study. All participants were submitted to anthropometric and stabilometric evaluation, and carried out a Chair stand test. Stabilometric parameters obtained from time [amplitude displacement of center of pressure (CoP)] and frequency (oscillations of CoP at sub 0.3 Hz and 1-3 Hz bands) domain analysis were used as the indicators of balance performance and sensorial integration, respectively.
Results: Our results revealed that the CoP amplitude displacement was significantly greater in the older aged group, without differences in spectral bands, while the performance in the Chair stand test was smaller in the older aged group.
Conclusion: These data indicate that the age-associated postural control impairment is explained by the lower limb strength declines, but not by the age-associated changes in sensorial integration.

Introduction: The anterior division of the internal iliac artery (ADIIA) is a crucial vascular structure that supplies blood to the pelvic organs, perineum, and gluteal region. The present study demonstrates practical data concerning the anatomy of the ADIIA and its branches. It is hoped that the results of the current study may aid in localizing the pelvic arteries effectively.

Entrapment neuropathies of the lower extremity are often underdiagnosed due to limitations in clinical examination and electrophysiological testing. Advanced imaging techniques, particularly MR neurography and high-resolution ultrasonography (US), have significantly improved the evaluation and diagnosis of these conditions by enabling precise visualization of nerves and their surrounding anatomical structures. This review focuses on the imaging features of compressive neuropathies affecting the lumbosacral plexus and its branches, including the femoral, obturator, sciatic, common peroneal, and tibial nerves.
