Purpose: The purpose of this study was to determine if there were differences in lumbar range of motion between subjects carrying a posterior load and if wearing the load produced low back pain.

Subjects: The sample comprised of 24 young adults, of which 12 were randomly assigned to wear a load.

Methodology: Lumbar range of motion was measured and daily journals were kept by subjects to monitor pain levels. A bubble inclinometer was used according to AMA guidelines for pretest and posttest spinal measurements. Data were analyzed through the use of ANOVA, t-Tests, and the Mann-Whitney U-test.

Results: No significant differences were found in comparing lumbar ROM or pain levels between the two groups. Males had greater flexion and females had less flexion and extension while carrying a load versus those not carrying a load.

Conclusion: In order to prevent the occurrence of low back pain among children and young adults, physical therapists must play an active role in the education of back care and the prevention of low back pain.
