Article Synopsis
- The current evaluation of hip osteoarthritis (OA) severity relies on subjective methods, and this study aims to explore the use of objective gait analysis, specifically pelvis-thorax coordination, to assess disease severity.
- The study included three groups: healthy subjects, severe hip OA patients (requiring surgery), and less severe hip OA patients (not requiring surgery), with evaluations conducted before and after surgery for the severe group.
- Findings showed that pelvis-thorax coordination in the coronal plane correlated with clinical severity, effectively distinguished healthy individuals from OA patients, and reliably differentiated between surgical and non-surgical OA patients, suggesting its potential as an objective outcome measure in clinical trials.
Lower-limb intersegmental coordination is a complex component of human walking. Aging may result in impairments of motor control and coordination contributing to the decline in mobility inducing loss of autonomy. Investigating intersegmental coordination could therefore provide insights into age-related changes in neuromuscular control of gait.

The main reasons are the difficulty personalizing the ECC exercises by avoiding the muscle complications and the lack of information concerning the specific effects on the maximal capacities in CHF patients.
Aim: To compare - following a prior study on the feasibility and on the functional impacts - the effects on maximal capacities and tolerance in CHF of ECC training tailored by a low rate of perceived exertion (RPE) and those of conventionally tailored CON training.
Background: In 3D gait analysis, the knee joint is usually described by the Eulerian way. It consists in breaking down the motion between the articulating bones of the knee into three rotations around three axes: flexion/extension, abduction/adduction and internal/external rotation. However, the definition of these axes is prone to error, such as the "cross-talk" effect, due to difficult positioning of anatomical landmarks.

Unloader knee braces provide an interesting functional approach, which aims to modulate mechanical stress on the symptomatic joint compartment. We aimed to confirm the biomechanical effects and evaluate functional benefits of a new knee brace that combines a valgus effect with knee and tibial external rotation during gait in medial osteoarthritis patients.

- The study evaluated the safety and immediate effects of tailoring eccentric cycling exercise intensity based on perceived exertion from a prior submaximal concentric test among healthy adults.
- Participants engaged in three cycling tests to determine comfortable pedaling power and assess physiological responses during exercise, including oxygen uptake and cardiac metrics.
- Results indicated no adverse effects, with lower oxygen usage during eccentric cycling and a significant increase in stroke volume, suggesting this method of exercise prescription is feasible and well tolerated for future training.
Three-dimensional kinematics of the lower limbs in hip osteoarthritis during walking.

Objective: To describe the kinematic adaptations of all lower limb joints in hip osteoarthritis patients during walking.
Methods: Patients with unilateral primary hip OA, without associated joint disorders were included. Normal subjects were included as controls.
Objectives: Kinematic gait analysis consisting of measuring gait parameters (stride length, gait speed, dynamic joint angles) is a potential outcome measure in osteoarthritis (OA). The aim of this study was to evaluate its psychometric properties.
Methods: A systematic literature search was performed in PUBMED and the Cochrane database until January 2008 by selecting manuscripts assessing any psychometric property of gait analysis in knee or hip OA.
