Design outcomes

Primary

Measure	Time frame
To measure the difference in correct exercise performance of segmental stabilization exercises between the palpation group and the RUSI group as measured by the averaged preferential activation ratio (PAR) of the deep abdominal muscles in older adults with chronic lumbar back pain. Hypothesis: H0: The averaged preferred activation ratio (PAR) during segmental stabilization in older adults with chronic lumbar back pain does not differ between the palpation group and the RUSI group. H1: The averaged preferential activation ratio (PAR) during segmental stabilization in older adults with chronic lumbar back pain differs between the palpation group and the RUSI group.	—

Secondary

Measure	Time frame
Difference in speed of learning of SSE between the palpation group and the RUSI group, as measured by the number of repetition attempts to positive preferred activation ratio (PAR) of deep abdominal muscles in older adults with chronic lumbar back pain. Assessment of perception of deep abdominal muscle contraction in older adults with chronic lumbar back pain in the palpation group and the RUSI group. Difference in averaged preferred activation ratio (PAR) of deep abdominal muscles in standing and supine during SSE in older adults with chronic lumbar back pain. Acceptability of ultrasound-based feedback. Difference in subjective burden during exercise performance of SSE between the palpation group and the RUSI group in older adults with chronic lumbar back pain. Perception of user experience and comfort of wearing the body-mounted ultrasound-based handheld device.	—
