Abstract: BACKGROUND: Low back pain (LBP) is a common complaint in the
postnatal period. Physiotherapy has many techniques to apply for such
cases. OBJECTIVE: To investigate the effect of central postero-anterior
(PA) lumbar mobilization on muscle activity in postpartum LBP. METHODS: Forty-five females with chronic LBP at least three months
postnatal. Participants divided randomly and equally into three groups.
Group A (Study group) received PA lumbar mobilization plus traditional
treatment which consisted of Ultrasonic and Infra-red. Group B (Placebo
group) received placebo mobilization plus traditional treatment. Group C
(Control group) received traditional treatment only. All patients received 3
sessions/week for 4 weeks. Pain intensity, functional disabilities and
Surface EMG for recording para spinal muscle activity were measured before
and after intervention. Statistical analysis was done by ANOVA and paired
t-test. RESULTS: Central PA mobilization showed a significant reduction
(P< 0.05) in the average surface EMG activity of the erector spinae
musculature compared with the other groups as well as improvement in
functional ability and reduction in pain intensity. CONCLUSION: A central PA mobilization significantly reduced pain
intensity and surface EMG activity of erector spinae musculature as well as
improvement in functional ability in mechanical low back pain in postnatal
females.
