Use of physical performance tests in a group of Brazilian Portuguese-speaking individuals with low back pain.

Low back pain (LBP) is a prevalent condition across cultures, and the tools used for assessment of distinct groups need to be evaluated. Our goal was to investigate the psychometric properties of physical performance tests (PPTs) in a group of Brazilian Portuguese-speaking (BPS) individuals with LBP in a nonexperimental, descriptive study. BPS individuals with and without LBP were studied, and PPTs, self-report questionnaires, and VAS pain score were evaluated.

The reliability of walking tests in people with claudication.

Objective: To contrast the reliability of the 6-min walking test (6MW) with that of the shuttle walking test (SWT) in patients with intermittent claudication attributable to peripheral obstructive arterial disease (POAD), and to examine the relationships of the walking tests, medical outcomes, and hemodynamic variables.

Design: Twenty-three patients were randomly assigned to perform both walking tests on two different occasions. Total distance walked (DW), time of pain onset (PO), and time of limiting claudicating symptom (TLS) were analyzed.

Reliability of a portable gas analyzer during a 5-min walk test.

Objective: To determine the reliability of a gas analyzer while assessing oxygen consumption (.VO2) during a 5-min walking test.

Design: Forty healthy participants were connected to the KB1-C and walked for 5 mins on a 5-m walkway.

Reliability of measures of gait performance and oxygen consumption with stroke survivors.

This study assessed the reliability of gait performance with concurrent measures of oxygen consumption (VO2) in stroke survivors (SS). Nine male SS (60.00 +/- 15.

Differential responses to measures of gait performance among healthy and neurologically impaired individuals.

Objectives: To compare gait during a 5-minute walk among healthy individuals, persons with spinal cord injury (SCI), and stroke survivors and to investigate whether simultaneous measures of oxygen consumption enhance information about performance.

Design: Descriptive study.

Setting: Veterans Affairs medical center.
