[Relationship between lower extremity muscle strength and dynamic balance in people post-stroke].

Unlabelled: The purpose of this study was to determine how lower extremity muscle weakness is related to post-stroke difficulties in balancing.

Methods: Dynamic balance of 30 people post-stroke and 30 neurologically sound people was assessed by the Functional Reach Test and the Timed Up and Go Test. Bilateral lower extremity muscle strength was measured in classical manual muscle testing positions using a Lafayette instrument.

The dizzy patient: a review of etiology, differential diagnosis, and management.

Background: Dizziness is a lay term used to describe a variety of sensations. Unfortunately, the term "dizziness" does not have a precise medical definition, and additional information is typically required to further define the patient's problem.

Methods: When dizziness is a presenting complaint, distinctions must be made between vertigo (a sense of false movement), near-syncope (a feeling of impending faint), disequilibrium (loss of balance), and ill-defined lightheadedness (an inability to concentrate or focus the mind).

Timing and force control deficits in clumsy children.

This study investigated the link between cognitive processes and neural structures involved in motor control. Children identified as clumsy through clinical assessment procedures were tested on tasks involving movement timing, perceptual timing, and force control. The clumsy children were divided into two groups: those with soft neurological signs associated with cerebellar dysfunction and those with soft neurological signs associated with dysfunction of the basal ganglia.
