Why the study?
Lumbopelvic exercise monitoring has traditionally relied on single-channel analogue pressure units, limiting clinical translation of simultaneous transvaginal and external abdominal pressure assessment.
Design
Bench characterisation proof-of-concept study
Key result
A proof-of-concept digital dual-channel pressure biofeedback unit demonstrated high linearity (R2 > 0.99) with a mean absolute error of less than 1.1 mmHg during static bench characterization.

Enables simultaneous transvaginal-abdominal pressure monitoring in lumbopelvic exercise; leaves open clinical adoption pending validation trials.
Effect estimate: R2 > 0.99
A proof-of-concept digital dual-channel pressure biofeedback unit demonstrated high linearity and low error in bench testing, providing an open-hardware blueprint for lumbopelvic rehabilitation research.
Rafet Irmak (2026) studied Lumbopelvic rehabilitation. Digital dual-channel pressure biofeedback unit vs. Commercial pressure biofeedback units was evaluated on Static bench characterisation (20–100 mmHg) (R2 > 0.99). A proof-of-concept digital dual-channel pressure biofeedback unit demonstrated high linearity (R2 > 0.99) with a mean absolute error of less than 1.1 mmHg during static bench characterization.
