Abstract

Purpose: Lower extremity (LE) pain accounts for 13-20% of injuries in the active population. LE pain has been contributed to inflexibility and fascial restrictions. Deep oscillation therapy (DOT) has been proposed to improve range of motion and reduce pain following musculoskeletal injuries. Therefore, our objective was to determine the effectiveness of DOT on ankle dorsiflexion range of motion (ROM) and pain in individuals with and without lower-leg pain. Methods: We used a single blind, pre-post experimental study in a research laboratory. Thirty-two active participants completed this study. Sixteen individuals reporting lower-leg pain and sixteen non-painful individuals completed the study. Participants received a single session of DOT performed by one researcher to their affected limb or matched limb. The intervention parameters included a 1:1 mode and 70-80% dosage. The intervention began by stimulating the lymphatic channels at the cisterna chyli, the inguinal lymph node, and the popliteal lymph node at a frequency of 150 Hz all for a minute each. Next, the researcher treated the triceps surae complex for 11 minutes at three different frequencies. Finally, the participant was treated distal to the popliteal lymph node at 25 Hz for 5 minutes. The main outcome measures included pain using the VAS and ankle dorsiflexion ROM with the weight-bearing lunge test (WBLT). Statistical analyses included descriptive statistics and F-test comparisons between and within groups. Results: The average WBLT measures for all participants increased 0.6 cm, which not to the minimal detectable change for passive ankle dorsiflexion ROM. Significant differences from pre-post measures were identified for pain on the VAS. Conclusion: While increases in ROM were identified, the difference was not clinically important. DOT was successful in decreasing lower-leg pain.
