Background: Balance problems are common in children who have cerebral palsy (CP) but are active and ambulant. Control of the whole-body center of mass is critical in maintaining dynamic stability during challenging mobility tasks, such as clearing an obstacle while walking.
Objective: The objective of this study was to compare trunk and lower limb kinematics and center-of-mass control in children with CP and those in children with typical development during obstacle crossing.
Design: This was a cross-sectional study. Thirty-four children who were 5 to 17 years of age (17 with CP and 17 with typical development) and matched in age and height completed 2 gait trials involving crossing a 10-cm obstacle.
Methods: Three-dimensional kinematic and kinetic data were captured with a general-purpose 3-dimensional motion tracking system and forceplates. Trunk data were captured with a validated model.
Results: All children cleared the obstacle with similar hip and knee kinematics, step length, and single-support duration. In children with CP, step width was increased by 4.81 cm, and center-of-mass velocity was significantly slower at lead limb toe-off (0.31 m/s) and during lead limb clearance (0.2 m/s). Children with CP showed altered trunk and pelvis movement, characterized by significantly greater pelvic obliquity, pelvic tilt, and trunk rotation throughout the task, increased lateral trunk lean during lead limb crossing (3.7°), and greater sagittal trunk movement as the trail limb crossed (5.1°).
Limitations: The study was not powered to analyze differences between children with diplegia and those with hemiplegia.
Conclusions: Children with CP required greater adjustments at the trunk and pelvis to achieve successful obstacle crossing. The increase in trunk movement could have been compensatory for reduced stability distally or for a primary problem reflecting poor proximal control. The findings suggest that rehabilitation should focus on both proximal trunk control and distal stability to improve balance.

A retrospective analysis of quality of life domains impacted by distal radius fracture and ulnar neuropathy.

Background: Distal radius fractures (DRF) and ulnar neuropathy (UNE) present with reduced motor function, restricted range of motion, pain, and reduced grip strength that may lead to similar treatment approaches. With rapid and insidious onset for DRF and UNE, respectively, the contextual factors impacting an individuals' experience with the condition can vary.
Purpose: The aim of this secondary analysis is to compare ratings of quality of life (QoL) domains prior to treatment and 3 months post treatment for DRF and UNE.
Bioinspired origami-based soft prosthetic knees.

Prosthetic knees represent a prevalent solution for above-knee amputation rehabilitation. However, satisfying the ambulation requirements of users while achieving their comfort needs in terms of lightweight, bionic, shock-absorbing, and user-centric, remains out of reach. Soft materials seem to provide alternative solutions as their properties are conducive to the comfort aspect.

Methods: This is a preliminary analysis involving ten healthy volunteers and two patients with shoulder musculoskeletal disorders. The protocol was developed in two phases (III and IV) with different ROM limits and including flexion-extension (FE), external-rotation (ER) and internal-rotation (IR) exercises, performed at two speeds and both with and without NAO assistance.
A review of clopidogrel resistance in lower extremity arterial disease.

Objective: Lower extremity arterial disease (LEAD) is a prevalent condition that produces a significant burden on health care systems. Patients with LEAD have an increased risk of major adverse cardiovascular events as well as major adverse limb events. Despite significant variation in guidance on antiplatelet therapy for LEAD worldwide, many governing bodies recommend clopidogrel as the preferred single anti-platelet agent.

The unique saddle articulation of the trapeziometacarpal joint allows for a wide range of motion necessary for routine function of the thumb. Inherently unstable characteristics of the joint can lead painful instability. In this study, we modified a surgical dorsal ligament reconstruction technique for restoring trapeziometacarpal joint stability.
