Characterization of the vastus lateralis torque-length, and knee extensors torque-velocity and power-velocity relationships in people with Parkinson's disease.

Introduction: Parkinson's disease (PD) is a prevalent neurodegenerative condition observed primarily in the elderly population that gives rise to motor and non-motor symptoms, one of which is muscle weakness. The aim of this study was to characterize the vastus lateralis torque-fascicle length (T-L) and the knee extensors torque-angular velocity (T-V) and power-angular velocity (P-V) relationships in PD patients and to investigate the influence of muscle geometry on muscle mechanics.

Methods: Participants (11 PD: patients, 9 CR: age matched healthy controls; 10 CY: young healthy controls) performed: (i) isometric contractions (e.

Muscle shape changes in Parkinson's disease impair function during rapid contractions.

Aim: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized, among the others, by muscle weakness. PD patients reach lower values of peak torque during maximal voluntary contractions but also slower rates of torque development (RTD) during explosive contractions. The aim of this study was to better understand how an impairment in structural/mechanical (peripheral) factors could explain the difficulty of PD patients to raise torque rapidly.

Complications associated with lumbar discectomy surgical techniques: a systematic review.

Background: Open discectomy (OD) and microdiscectomy (MD) are routine procedures for the treatment of lumbar disc herniation. Minimally invasive surgery (MIS), such as micro-endoscopic discectomy (MED) and full endoscopic discectomy (FED), offers potential advantages (less pain, less bleeding, shorter hospitalisation and earlier return to work), but their complications have not yet been fully evaluated. The aim of this paper was to identify the frequency of these complications with a focus on MIS in comparison to OD/MD.

Improvement in motor symptoms, physical fatigue, and self-rated change perception in functional motor disorders: a prospective cohort study of a 12-week telemedicine program.

Background: Functional motor disorders (FMDs) are highly disabling conditions associated with long-term disability, poor quality of life, and economic burden on health and social care. While multidisciplinary 5-days rehabilitation programs have been shown to reduce motor and non-motor symptoms, long-term management and monitoring in FMDs remain an unmet need.

Aim: To compare a 12-weeks telemedicine program against a 12-weeks self-management program after a 5-days rehabilitation program for improving motor, non-motor symptoms, quality of life, and perception of change in patients with FMDs.

Motor and non-motor outcomes after a rehabilitation program for patients with Functional Motor Disorders: A prospective, observational cohort study.

Background: Rehabilitation has proven effective in improving motor symptoms (i.e., weakness, tremor, gait and balance disorders) in patients with Functional Motor Disorders (FMDs).
