Relationship between lower limb coordination and walking speed after stroke: an observational study.

Background: Although lower limb muscle strength is associated with walking performance in people after stroke, even when there is good strength, walking speed may remain slower than normal, perhaps due to incoordination.

Objective: The aim of this study was to examine the relationship between walking speed and lower limb coordination in people with good strength after stroke.

Methods: An observational study was conducted with 30 people with stroke and 30 age-matched controls.

Ischemic stroke related to intracranial branch atheromatous disease and comparison with large and small artery diseases.

Background: The mechanism of ischemic stroke in intracranial branch atheromatous disease (BAD) is different from large artery atherothrombotic disease (LAD) or lacunar infarction (LACI). The concept of BAD is underused in clinical practice and research.

Methods: Patients admitted over 24-months with ischemic stroke caused by atherosclerotic disease were reviewed retrospectively and classified according to radiological±clinical criteria into LAD, BAD and LACI.

Cloning and characterization of novel PDE4D isoforms PDE4D6 and PDE4D7.

We report here the cloning and characterization of two novel PDE4D isoforms, PDE4D6 and PDE4D7. PDE4D6 is a supershort form and PDE4D7 a long form of PDE4D. In addition, we have identified another novel long-form variant, PDE4D8, in silico.

Relations among physical activity, physical fitness, and self-perceived fitness in Hong Kong adolescents.

The relationships between physical fitness, activity, and self-perceived fitness in adolescents in Hong Kong were investigated. Regular physical activity patterns, self-perceptions of fitness, and health-related physical fitness were measured in 201 secondary school students (M age = 13.8 yr.
