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. Thirty participants involved in the reliability study were also assessed and reassessed for the ability to complete the STSTS conditions by PHC providers.

Results: Outcomes of the STSTS test, except the condition with arms on a walking device, could significantly discriminate lower extremity muscle strength (LEMS) and mobility of the participants (r_pb = -0.58 to 0.69) with moderate concurrent validity. Outcomes of the tests without using the arms also showed moderate to almost-perfect reliability (kappa = 0.754-1.000) when assessed by PHC raters.

Conclusion: The findings suggest the use of an STSTS with arms free by the sides as a standard practical measure by PHC providers to reflect LEMS and mobility of ambulatory individuals with SCI in various clinical, community, and home-based settings.
