High-intensity interval training and pulmonary hemodynamics in COPD with hypoxemia.

Background: Exercise is recommended for all patients with COPD. Evidence for its benefit is considerably weaker in the more severe stages of the disease. The aim of this study was to investigate whether high-intensity interval training could improve exercise capacity, pulmonary hemodynamics and cardiac function in patients with severe COPD and hypoxemia.

Dopaminergic modulation of semantic priming in Parkinson disease.

Objective: Our purpose is to examine the effect of D2/D3 agonists on semantic priming.

Background: Dopamine seems to restrict the semantic network in semantic priming. However, which dopamine receptor mediates this effect is unknown.

Reliability and validity of the Tinetti Mobility Test for individuals with Parkinson disease.

Background And Purpose: This study examined the interrater and intrarater reliability, concurrent validity, and criterion validity of the Tinetti Mobility Test (TMT) as a fall risk screening tool in individuals with Parkinson disease (PD).

Subjects: Thirty individuals with PD voluntarily participated in the study, and data from a retrospective review of 126 patient records were included.

Methods: Physical therapists and physical therapist students rated live and videotaped performances of the TMT.
