Hypothesis
Does the Mulligan's Sustained Natural Apophyseal Glide (SNAG) technique increase lumbar flexion range of motion in asymptomatic subjects?
Conclusion
The SNAG technique did not show significant differences in lumbar flexion range of motion compared to sham mobilisation.
Supporting Evidence
- The SNAG technique was applied at the L3 and L4 spinal levels.
- No significant differences were observed in lumbar ROM between the SNAG and sham groups.
- Intra- and inter-day reliability of flexion measurements was high.
Takeaway
The study tested a technique to help people bend better, but it didn't really work better than a fake treatment.
Methodology
49 asymptomatic volunteers were randomly assigned to receive either SNAG mobilisation or sham mobilisation, with lumbar ROM measured before and after each technique.
Potential Biases
Potential bias from the therapist's subjective application of force during the SNAG technique.
Limitations
The study used an asymptomatic population, which may not reflect clinical practice; measurement errors may have occurred due to the device used.
Participant Demographics
49 asymptomatic volunteers (20 males, 29 females), ages 18-32 (mean: 21 years).
