| Abstract | OBJECTIVE: To find the position that provided the most comfort, as well as the widest L3-L4 interlaminar space opening. DESIGN: Pilot study. SETTING: Operating room. PATIENTS: Thirty-two healthy volunteers. INTERVENTIONS: L3-L4 interlaminar space was measured on volunteers assuming a baseline position (sitting upright) and 5 study positions: (1) sitting in fetal position, (2) sitting on a table tilted at 30°, (3) sitting while hugging an exercise ball, (4) sitting with midcalves on the table's edge, and (5) lying on one side in fetal position. Interlaminar spaces were measured to determine which position resulted in the largest interlaminar space compared with baseline. The comfort level of each position was rated by subjects using a visual analogue scale from 1 to 10. MAIN RESULTS: The means of the interlaminar openings in all study positions were significantly different from baseline, with the 'sitting fetal' having the greatest difference, (1.32mm, P<.001), followed by 'hugging a ball' (0.94mm, P<.001) and 'lying fetal' (0.92mm, P<.001). Alternatively, when using 'sitting fetal' (a more commonly used position) as a comparative baseline, 'hugging a ball' and 'lying fetal' showed smaller but not significantly different interlaminar openings (Δ=-0.38mm, P value = .221 and Δ=-0.40mm, P value = .164, respectively).'Sitting on a tilted table' and 'sitting midcalf' showed significantly smaller interlaminar openings (Δ=-0.52mm, P value = .025 and Δ=-0.72mm, P value < .001, respectively) when compared with the alternative baseline of 'sitting fetal.' Mean visual analogue scale scores for comfort showed that 'hugging a ball' (7.8/10), 'lying fetal' (7.5/10), and 'sitting fetal' (7.2/10) positions had the highest ratings. CONCLUSIONS: Ultrasonographic measurements carried out on 32 subjects showed that 'sitting fetal,' 'lying fetal,' and 'hugging a ball' positions provided the widest L3-L4 interlaminar openings. These 3 positions were also found to be more comfortable. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
