Introduction: In this study, we aim to evaluate the efficacy and safety of limb cyclical pressure device (LUXURY-ZAM) in healthy working people with long-standing posture for relief of leg pain and swelling.
Methods: This study is designed to compare the treatment effect of LUXURY-ZAM. All subjects had no known acute and chronic disease and had to participate in three sessions: 1) natural resting, 2) sequential pressure mode and 3) cyclical pressure mode with LUXURY-ZAM. Before these sessions, the subject visited after long-standing work, and measured outcome parameters at 0min (T1) before intervention, 30min (T2) after intervention. During the natural resting session, the subjects rested in supine position without any therapeutic intervention, although both sequential and cyclical pressure session treated with LUXURY-ZAM for 30 min. The difference between the sequential and cyclical pressure method is whether the initial chamber, which there have five chambers, continue or decrease its pressure after the next chamber is operated. In the cyclical pressure method, the pressure sustain until the last chamber is operated. We measured leg pain with visual analogue scale (VAS) as a primary outcome, and leg circumference (cm) and volume (ml) were evaluated as a secondary outcome.
Results: Total twenty healthy adults were enrolled and mostly were women (95%), mean age of 37.8, working as a nurse or nurse’s aide (75%). VAS in all three sessions was improved 30 min after working significantly, but the therapeutic groups of cyclical and sequential pressure mode decreased the 3 times more score (p<0.001) (Table 1). Similarly, the mean value of leg volume after resting, cyclical and sequential treatment significantly decreased in all subjects after 30 minutes of intervention, however difference from T1 to T2 among groups was not significant (Table 2). The leg circumference also declined noticeably, and these therapeutic effects in both sequential and cyclical sessions were superior to resting session (Table 3). In the post-hoc analysis, the differences between resting and cyclical mode, and between resting and sequential mode were statistically significant in VAS and leg circumferences, although the comparison between sequential and cyclical mode did not show significant difference.
Conclusion: In this study, LUXURY-ZAM can consider as an efficient and safe therapeutic option for relief of leg pain and edema in healthy adults. However, there were no significant differences between sequential and cyclical mode. |
