Trunk Control Tests in Post-stroke Context: Validity and Reliability Study

MicroFET 2 Handheld Dynamometer is a force evaluation testing device to evaluate the strength of various trunk muscle groups in flexion, extension, and lateral (N).

"The BASS is a test to assess static and dynamic sitting and standing balance, which has been validated for post-stroke hemiparetic patients. Each test is evaluated by a score from 0 (patient needs external support) to 4 (stable without external help) for static condition and from 0 (no possibility to pick up objects) to 3 (objects picked up without external help) for dynamic condition. The maximal score (sitting, standing, static and dynamic) is 14 points."

The participant sits on a chair, gets up, walks 3m, makes a half turn in 1m2, walks 3m and comes back to sit on the chair. The time (s) to complete the task is measured.

The MFRT is a dynamic seated balance test that measures the trunk's ability to move forward, to the paretic and non paretic side (cm).

The joint positional sense test of the trunk consists in evaluating the positional error of the trunk in the sagittal plane (mm) and in the frontal plane (mm) during a trunk flexion posture (target position).

This test evaluates the balance capacities of the subject in an unstable sitting position on a seesaw (mediolateral or anteroposterior instability) with forceplate and phone application using center of pressure variables: total displacement (mm), area (mm2), deltas (mm), mean velocity (mm/s) et maximal velocity (mm/s).
