Laird, Robert A., Peter Kent, and Jennifer L. Keating. “How consistent are lordosis, range of movement and lumbo-pelvic rhythm in people with and without back pain?.” BMC Musculoskeletal Disorders 17.1 (2016): 403.

Normative values provided in the ViMove2 assessment reports are based on an analysis of lumbo-pelvic range of motion in 50 adults with no history of chronic lower back pain (LBP). Participants in the study were guided through a set of simple standardised postures and movements, in standing and sitting positions, while wearing ViMove sensors. Range of motion data collected included standing lordosis, flexion, extension, lateral flexion, and pelvic tilt (anterior and posterior) in sitting and standing. The age range for the normative data collection was 19-62 (mean 35 ± 12). Normative data has not been collected outside this age range. Data was stratified according to age groups (18-29, 30-39, 40-49, 50-65). The following table summarises the ViMove2 normative values established for males and females combined. Normative data was calculated for each age group, with the values summarised below presented as the minimum and maximum mean over all age groups.

NOTE: The normative values displayed in the ViMove2 Live Assessment reports are based on the mean and 95% confidence intervals calculated for each age group, using combined male and female values.
