The "DUC" trial: a pilot randomized controlled trial of immediate versus delayed cord clamping in preterm infants born between 24 and 32 weeks gestation.

Purpose: To determine the feasibility of a randomized controlled trial of delayed umbilical cord clamping in preterm infants.

Methods: Following informed consent, women between 24 to 32 weeks gestation experiencing imminent preterm birth were randomly assigned to either an immediate cord clamping (ICC) or delayed cord clamping (DCC) group. Umbilical cord clamping directions were 0-15 s for the ICC group and 30-45 s for the DCC group.

Water-based exercise for cardiovascular fitness in people with chronic stroke: a randomized controlled trial.

Objective: To evaluate the effect of an 8-week, water-based exercise program (experimental group) with that of an upper-extremity function program (control group) to increase cardiovascular fitness within a community setting for people with stroke.

Design: Single-blind randomized controlled trial.

Setting: Public community center.

Submaximal exercise in persons with stroke: test-retest reliability and concurrent validity with maximal oxygen consumption.

Objective: To establish the test-retest reliability and concurrent validity with maximum oxygen consumption (VO2max) for 3 submaximal exercise tests in persons with chronic stroke: (1) submaximal treadmill test, (2) submaximal cycle ergometer test, and (3) 6-minute walk test (6MWT).

Design: Prospective study using a convenience sample.

Setting: Free-standing tertiary rehabilitation center.

A community-based group exercise program for persons with chronic stroke.

Purpose: The purpose of this study was to evaluate the physical and psychosocial effects of an 8-wk community-based functional exercise program in a group of individuals with chronic stroke.

Methods: Twenty-five subjects (mean age 63 yr) participated in a repeated measures design that evaluated the subjects with two baseline assessments 1 month apart, one postintervention assessment, and one retention assessment 1 month postintervention. Physical outcome measures assessed were the Berg Balance Test, 12-Minute Walk Test distance, gait speed, and stair climbing speed.

A moderate dose of pseudoephedrine does not alter muscle contraction strength or anaerobic power.

Objective: To investigate the effect of an acute oral administration of pseudoephedrine (PSE) on muscle function, fatigue, and anaerobic power output.

Design And Materials: Healthy males (N = 10) and females (N = 10) were allocated to receive both a placebo and PSE (120 mg) using a randomized, double-blind, crossover experimental design. Each subject had their maximal voluntary contraction strength and fatigability measured for both handgrip and ankle dorsi-flexion.

Reliability and comparison of weight-bearing ability during standing tasks for individuals with chronic stroke.

Objectives: To determine the test-retest reliability over 2 separate days for weight-bearing ability during standing tasks in individuals with chronic stroke and to compare the weight-bearing ability among 5 standing tasks for the paretic and nonparetic limbs.

Design: Prospective study using a convenient sample.

Setting: Free-standing tertiary rehabilitation center.

Incidence of exercise-induced arterial hypoxemia in prepubescent females.

Due to the recent discovery of exercise-induced arterial hypoxemia (EIAH) in healthy active women with normal levels of peak oxygen uptake (V'(O(2)peak), this study examined the incidence of EIAH in prepubescent females. Nineteen healthy, active, prepubescent females (X +/- SD: age = 11.1 +/- 1.

Functional walk tests in individuals with stroke: relation to perceived exertion and myocardial exertion.

Background And Purpose: Functional walk tests such as the 6- and 12-Minute Walk Test (ie, 6MWT and 12MWT, respectively) are submaximal measures used to determine functional capacity in individuals with compromised ability. The purpose of this study was to determine the relationship between these walk tests and measures of exertion (perceived and myocardial), in addition to impairment in individuals with stroke. The relationship among the 6MWT, 12MWT, and the more traditionally assessed measure of self-paced gait speed (generally assessed over a short distance, eg, 10 m) was also evaluated.
