A Biokinetic Approach in Primary Knee Osteoarthritis Prevention and Management - Exploring Movement Profiles and Kinetic Chain Interactions: Current Concepts.

Knee osteoarthritis (OA) is a chronic disease characterized by increasing prevalence and significant physical, psychological, and economic burdens. Despite extensive research, the definition, risk factors, and effective cost-efficient treatments for knee OA remain unclear. This article aims to revisit primary knee OA, understanding its etiology, and focusing on prevention and individualized non-operative treatment modalities.

Gait kinematics of osteoarthritic knees after intra-articular viscosupplementation: A double-blinded randomized controlled trial.

Background: The utilization of subjective questionnaires for assessing conservative treatment in knee osteoarthritis may present challenges in identifying differences due to inadequate statistical power. Objective tools, such as three-dimensional (3D) kinematic analysis, are accurate and reproducible methods. However, no high-quality studies assessing the effects of intra-articular viscosupplementation (VS) have been published.

Short-term foot warming impacts foot sensitivity and body sway differently in older adults.

Background: Aging is accompanied by loss of foot skin sensitivity and reduced postural control. Increasing foot temperature can improve both skin sensitivity and postural control in adults. However, it remains unclear whether similar effects can be observed in older adults.

Effects of increasing temperature in different foot regions on foot sensitivity and postural control in young adults.

Despite controversial evidence, foot sensitivity may influence postural control. Since skin temperature changes may induce changes in skin sensitivity, it remains unclear whether this also affects postural control. Here we examined the effects of increasing foot temperature on foot sensitivity and postural control responses.

Steadiness training improves the quadriceps strength and self-reported outcomes in persistent quadriceps weakness following nine months of anterior cruciate ligament reconstruction and failed conventional physiotherapy.

Background Persistent quadriceps weakness may occur after anterior cruciate ligament reconstruction, limiting the strength gain. However, steadiness strengthening might change the inability to gain strength. Hence, we determined whether strength training with force steadiness and visual biofeedback can improve knee quadriceps torque, self-reported pain and knee stability in patients with persistent quadriceps weakness after knee anterior cruciate ligament reconstruction.

Programming course for health science as a strategy to engage students during the coronavirus pandemic.

Programming is an important skill for different areas of knowledge. While in the past, programming skills were much more related to fields of computer sciences and engineering, today, professionals from different areas benefit from the ability to write codes for different applications. Furthermore, programming stimulates logical thinking, which impacts other personal abilities.

Correlation between lower limb isometric strength and muscle structure with normal and challenged gait performance in older adults.

Background: Muscular parameters have been considered to influence gait of older adults, but it is still unclear which specific lower limb muscular parameters correlate with kinematics of overground and obstacle crossing in older adults.

Research Question: What lower limb muscular parameters correlate and explain kinematics of overground walking and obstacle crossing ability in the elderly?

Methods: Muscle structure was evaluated in 15 older individuals (75.4 ± 5 years) through measures of architecture (muscle thickness, fascicle length, and pennation angle) and muscle quality (echo intensity) from lower limb muscles (vastus lateralis, biceps femoris, rectus femoris, tibialis anterior, and gastrocnemius medialis).

IS MUSCULAR AND FUNCTIONAL PERFORMANCE RELATED TO GAIT SYMMETRY IN OLDER ADULTS? A SYSTEMATIC REVIEW.

Background: Gait asymmetries are a matter of discussion concerning gait adaptation in older adults. While most studies perform unilateral gait assessments, the hypothesis that asymmetry in gait biomechanics is influenced by muscular and functional performance in older people needs to be confirmed.

Purpose: Here we performed a systematic review (CRD42018093189) to discuss the relationship between muscular and functional performance and gait asymmetries in older adults.

Does physical exercise improve obstacle negotiation in the elderly? A systematic review.

Background: Physical exercise improves walking in the elderly but much less is known about its effect on more challenged gait, such as obstacle negotiation. We conducted a systematic review to discuss the effects of regular physical exercise on kinematics and kinetics of obstacle negotiation in the elderly.

Methods: A comprehensive literature search revealed 859 citations for review, whereof 206 studies entered the full-text analysis.
