McGilltrunkenduranstest

McGilltrunkenduranstest is a standardized assessment protocol designed to quantify trunk stability and muscular endurance under sustained postural load. It combines dynamic perturbations with endurance timing to evaluate neuromuscular control of the core and spine, as well as resilience to fatigue. The test aims to provide objective metrics that can inform rehabilitation, athletic training, and balance screening.

Procedure: In a controlled laboratory setting, participants assume a specified posture (standing or seated) with the pelvis secured to a low-friction support. A computerized platform generates controlled perturbations (tilts, translates, or sudden nudges) at predefined intervals. The protocol typically lasts 60 to 180 seconds per trial, with multiple trials per session. Outcome measures include trunk sway metrics, time-to-perturbation failure, peak corrective torque, and fatigue slope derived from performance decline over time.

Origins and development: The protocol was developed at McGill University in the early 2000s by researchers in kinesiology and biomedical engineering. The name reflects the institution (McGill), the construct being assessed (trunk endurance), and the measurement focus (duration). Since its introduction, variations have emerged to adapt the test to clinical populations and field settings.

Applications and evaluation: McGilltrunkenduranstest has been reported in rehabilitation and sports science literature as a feasible measure of core endurance and postural control. It is used to monitor progress in patients with back or balance disorders and to assess baseline risk of instability. Limitations include equipment requirements and protocol heterogeneity across studies.
