Reliability and concurrent validity of 30-s and 5-time sit-to-stand tests in older adults with knee osteoarthritis.

Introduction: Sit-to-stand (STS) movement is fundamental in daily life. STS tasks have been used to assess lower limb muscle strength, balance control, and functional abilities in various populations, but limited information is available on their use in older individuals with knee osteoarthritis.

Objective: We here examined the intra-rater, inter-rater, and test-retest reliability of the 30-s and 5-time STS tests, and calculated the standard error of measurement (SEM) and minimal detectable change (MDC).

The Use of a Single-Time Sit-To-Stand Test in Ambulatory Individuals With Spinal Cord Injury by Primary Health Care Providers.

Background: The uncertain health care situations, such as that created by the COVID-19 pandemic, has limited hospital access and facilitated a paradigm shift in health care toward an increased demand for standard home visits and community-based rehabilitation services, including by ambulatory individuals with spinal cord injury (SCI).

Objectives: This 6-month prospective study explored the validity and reliability of a single-time sit-to-stand (STSTS) test when used by primary health care (PHC) providers, including a village health volunteer, caregiver, individual with SCI, and health professional.

Methods: Eighty-two participants were assessed for the STSTS using four arm placement conditions (arms on a walking device, arms on knees, arms free by the sides, and arms crossed over the chest) and standard measures, with prospective fall data follow-up over 6 months.

Responsiveness and minimal clinically important difference of the five times sit-to-stand test in ambulatory individuals with spinal cord injury: A six-month prospective cohort study.

Objectives: To explore the responsiveness and minimal clinically important differences of the five times sit-to-stand test in ambulatory individuals with spinal cord injury.

Methods: This six-month prospective cohort study was conducted in 109 individuals with spinal cord injury who could walk with or without a walking device for at least 10 meters. Participants were assessed for the five times sit-to-stand test in the four arm-placement conditions and standard measures to determine responsiveness of the test, at baseline, and one, three, and six months.

Outcomes of the five times sittostand test could determine lower limb functions of ambulatory people with spinal cord injury only when assessed without hands.

Various clinical application of the five times sit-to-stand test (FTSST), with or without hands, may confound the outcomes to determine the lower limb functions and mobility of individuals with spinal cord injury (SCI). This study assessed the concurrent validity of the FTSST in ambulatory individuals with SCI who completed the test with or without hands as verified using standard measures for lower extremity motor scores (LEMS) and functional mobility necessary for independence and safety of these individuals. Cross-sectional study.

Five times sit-to-stand test for ambulatory individuals with spinal cord injury: a psychometric study on the effects of arm placements.

Study Design: A psychometric study.

Objectives: To investigate the reliability and the concurrent validity of the five times sit-to-stand test (FTSST) during various arm placement conditions in ambulatory participants with spinal cord injury (SCI). In addition, the difficulty of the FTSST during various arm placement conditions was compared using the number, characteristics, and physical ability of those who could complete the conditions.

Increased Lower Limb Loading During Sit-to-Stand is Important for the Potential for Walking Progression in Ambulatory Individuals with Spinal Cord Injury.

Background: Decreased rehabilitation time may increase the need for walking devices at the time of discharge to promote levels of independence among ambulatory individuals with spinal cord injury (SCI). However, using walking devices could create adverse effects on patients. This study explores the proportion of walking devices used, potential for walking progression, and associated factors among ambulatory individuals with SCI.

Importance of independent sit-to-stand ability in ambulatory patients with spinal cord injury.

Background: Sit-to-stand (STS) is an important and basic activity for daily living. However, a few studies have reported information relating to STS ability in ambulatory patients with spinal cord injury (SCI).

Aim: To investigate factors associated with the ability of independent sit-to-stand (iSTS) among ambulatory patients with SCI.
