Open AccessAnalysis of the obstetrician's posture and movements during a simulated forceps delivery
The objective of this study was to identify and qualify, by means of a three-dimensional kinematic analysis, the postures and movements of obstetricians during a simulated forceps birth, and then to study the ...

Open AccessDoes the McRoberts’ manoeuvre need to start with thigh abduction? An innovative biomechanical study
Guidelines and description about the achievement of the McRoberts manoeuvre are discordant, particularly concerning the need for abduction before the beginning of the manoeuvre. We sought to compare the biomec...

Open AccessAssessment of Pelvic-Lumbar-Thigh Biomechanics to Optimize The Childbirth Position: An “In Vivo” Innovative Biomechanical Study
The study aimed to assess the associations between the pelvis orientation, lumbar curve and thigh postures throughout pregnancy in a population of healthy women. Additionally, optimal mechanical birth conditio...

Open AccessIs there an impact of feet position on squatting birth position? An innovative biomechanical pilot study
The squatting birth position is widely used for “natural” birth or in countries where childbirth occurs in non-medical facilities. Squatting birth positions, like others, are roughly defined so a biomechanical...

In vivo assessment of the levator ani muscles using shear wave elastography: a feasibility study in women
We hypothesized that shear wave elastography (SWE) technology might be useful for assessing the elastic properties of the pelvic floor in women. Our primary objective was to evaluate the feasibility of assessi...

Is increased peripheral ligamentous laxity in term pregnant women associated with obstetric anal sphincter injury?
Increased ligamentous laxity is associated with pelvic floor distension in pregnant women. This considered, it may also be related to the risk of obstetric anal sphincter injury (OASI). Our objective was to as...

Is levator hiatus distension associated with peripheral ligamentous laxity during pregnancy?
The impact of pregnancy on pelvic floor disorders remains poorly understood. During pregnancy, an increase in ligamentous laxity and pelvic organ mobility is often reported. Our main objective was to investiga...

Proposition of a protocol to evaluate upper-extremity functional deficits and compensation mechanisms: application to elbow contracture
Instrumented gait analysis is widely accepted as an objective assessment of lower-extremity function. Conversely, upper-extremity function suffers from lack of objective evaluation. The present paper aims at ...

Personalized Physical Activity Monitoring Using Wearable Sensors
It is a well-known fact that exercising helps people improve their overall well-being; both physiological and psychological health. Regular moderate physical activity improves the risk of disease progression, ...

Conjunct rotation: Codman’s paradox revisited
This contribution mathematically formalizes Codman’s idea of conjunct rotation, a term he used in 1934 to describe a paradoxical phenomenon arising from a closed-loop arm movement. Real (axial) rotation is dis...

Joint-specific disruption of control during arm movements in Parkinson’s disease
The leading joint hypothesis (LJH) suggests distinct types of control (leading and subordinate) at different joints during multi-joint movements. Taking into account specific features of movements in Parkinson...

Submovements during pointing movements in Parkinson’s disease
Velocity irregularities frequently observed during deceleration of arm movements have usually been interpreted as corrective submovements that improve motion accuracy. This hypothesis is re-examined here in ap...

Spatial synchronization of an insole pressure distribution system with a 3D motion analysis system for center of pressure measurements
Insole pressure systems are often more appropriate than force platforms for analysing center of pressure (CoP) as they are more flexible in use and indicate the position of the CoP that characterizes the conta...

Open AccessOrigins of submovements in movements of elderly adults
Slowness is a well-recognized feature of movements in aging. One of the possible reasons for slowness suggested by previous research is production of corrective submovements that compensate for shortened prima...

Efficient control of arm movements in advanced age
The present study addresses the influence of aging on the ability to regulate mechanical effects arising during arm movements due to the multi-joint structure of the arm. Two mechanical factors were considered...
