Changes in Spinal Height Following Sustained Lumbar Flexion and Extension Postures: A Clinical Measure of Intervertebral Disc Hydration Using Stadiometry

Effects of seated lumbar extension postures on spinal height and lumbar range of motion during prolonged sitting

“…Email: rungthip@kku.ac.th Ergonomics, 2015http://dx.doi.org/10.1080/00140139.2015 recovery based on the concept of gravity elimination (e.g. Healey et al 2005;Owens et al 2009;Rodacki et al 2005). However, these postures required participants to lie down and they also took a long recovery period (10 -30 min).…”

Estimation Bias: Body Mass and Body Height in Endurance Athletes

“…A significant increase in body height was recorded after both supine flexion and prone extension lying. The mean height gain was 3.11 mm using prone extension and 3.19 mm using the supine flexion protocol (Owens, et al, 2009). increased although they trained regularly (Pollock, et al, 1997) thus leading to a higher body mass than expected. Presumably also these athletes felt they were training hard for a difficult event, and thus were motivated to perceive their athletic and physical capabilities as very high.…”

Ergonomic Impact of Spinal Loading and Recovery Positions on Intervertebral Disc Health: Strategies for Prevention and Management of Low Back Pain

“…Moreover, much of the research has been performed on young, healthy individuals. More research involving patients with known disc degeneration will allow greater generalizability.Supine flexed postures (Figure 1) have been shown to provide a similar hydration effect on the lumbar IVD (Owens et al, 2009). Other alternative recovery positions have been shown to facilitate hydration of the lumbar IVD (Figure 2 A & B) (Gerke et al 2010).…”

“…Stadiometry and MRI are the two primary methods of measuring spinal height change following loading and recovery conditions. Stadiometry has been shown to be a valid and reliable clinical tool to assess spinal height when compared to quantifiable measures made from MRI (Kanlayanaphotporn et al, 2002;Kourtis et al, 2004;Owens et al, 2009;Pennell et al, 2012). Stadiometry assessment has advantages over MRI in terms of costs, use in clinical setting, as well as the ability to measure subjects that simultaneously sustain compressive loads of the trunk.…”

“…Additional studies have demonstrated that sustained supine flexion and sidelying flexion position also increase spine height following periods of seated loading. (Gerke et al, 2011;Owens et al, 2009). …”
