Correlation between palpatory assessment and pressure sensors in response to postural trunk tests

BACKGROUND: The evaluation of postural trunk muscle function is a critical component clinical assessment in patients with musculoskeletal pain and dysfunction. Postural activation the muscles has been evaluated by various methods. This study evaluates correlation between subjective an objective measurement abdominal wall expansion. METHODS: Twenty-five healthy participants (16 women, 9 men, age 22.4 years) were assessed. was performed two experienced Dynamic Neuromuscular Stabilization (DNS) clinicians evaluating quality stabilization using five stability tests through palpation observation. Interrater reliability determined intraclass coefficients (ICC). Objective new device (DNS Brace) which externally measures pressure. Spearman rank correlations calculated for both observation DNS Brace data. RESULTS: interrater (ICC2,k) estimates demonstrated moderate three tests: Hip flexion test, Diaphragm & Intra-abdominal pressure regulation test (IAPRT) (ICC = 0.645–0.707). For measures, good found IAPRT 0.835), reliability: Breathing Stereotype 0.577–0.695). Correlation analysis several to strong brace values (Assessor 1): IAPRT, rs= 0.580, p= 0.002, 0.543, 0.005, 2): 0.776, p< 0.001, Stereotype, 0.625, 0.519, 0.008, Flexion 0.536, 0.006, Arm Elevation 0.460, 0.021. observation, 0.472, 0.017, 2) 0.540, 0.475, 0.016, 0.485, 0.014, Elevation, 0.451, 0.024. CONCLUSION: Based on inter-rater trained professionals, may prove useful when assessing asymptomatic individuals. More research needed order establish utility testing back populations. must be supplemented further examinations definitive decision making.
