Two-minute standing endurance test for axial postural abnormalities in patients with Parkinson's disease.

Background: Photo-based measurement methods are used to assess axial postural abnormalities (PA) in Parkinson's disease (PD). However, they capture only moments in time. We developed the 2-minute standing endurance test (2 M-SET), which specifically captures temporal changes in posture, as a novel dynamic method for measuring axial PA in patients with PD.

Test-retest reliability and minimal detectable change of the Balance Evaluation Systems Test and its two abbreviated versions in persons with mild to moderate spinocerebellar ataxia: A pilot study.

Background: The reliability of the evaluation of the Balance Evaluation Systems Test (BESTest) and its two abbreviated versions are confirmed for balance characteristics and reliability. However, they are not utilized in cases of spinocerebellar ataxia (SCA).

Objective: We aimed to examine the test-retest reliability and minimal detectable change (MDC) of the BESTest and its abbreviated versions in persons with mild to moderate spinocerebellar ataxia.

Lung Insufflation Capacity with a New Device in Amyotrophic Lateral Sclerosis: Measurement of the Lung Volume Recruitment in Respiratory Therapy.

Objective: The aim of this study was to validate the usefulness of the measurement of lung insufflation capacity (LIC) using the LIC TRAINER (LT) in patients with amyotrophic lateral sclerosis (ALS).

Methods: This retrospective study was conducted in the rehabilitation departments of the Japanese National Center of Neurology and Psychiatry and involved 20 ALS patients who underwent respiratory therapy between April 1, 2014, and December 2017. The vital capacity (VC), maximum insufflation capacity (MIC), and LIC measurements at the start of respiratory therapy were extracted from the medical records, and patients were divided into three groups: group A, VC could not be measured; group B, VC could be measured, but MIC was less than VC; and group C, MIC was larger than VC.
