Abstract

BACKGROUND AND AIM OF THE INVESTIGATION: Deep oscillation refers to an electromechanical therapy method in which electrostatic attraction and friction, produced by the use of a hand-held applicator, create resonance vibrations in treated tissue. In a pilot clinical trial the impact of deep oscillation has been examined in relation to the physiological parameters of wound healing on postoperative wounds.

MATERIAL AND METHODS:

Following osteosynthesis operations (extremities and spinal column), 40 patients were stratified by operation localisation and randomised into two samples (intervention [n = 20], control [n = 20]). Aside from primary care of the operation wound, finding-oriented deep oscillation was applied for at least one week following the operation in the intervention sample. The intra-individual reduction in postoperative pain occurrence between day 2 and day 7 of the postsurgical period was quantified by means of a visual analogue scale (VAS) serving as primary clinical end point from the patient's point of view. Confirmatory analysis of this primary endpoint was based on a two-sample Wilcoxon test at the 5 % level of significance.

RESULTS:

According to VAS pain occurrence declined in the intervention group from day 2 to day 7 in the postoperative period by a median of 3 points (P) (quartile range -4-0.25 P) and a mean of -2.3 P, the control group remained (almost) unaltered with a median difference of 0 P (-2-0 P) and a mean difference of -0.85 P; the treatment groups differed significantly in the postoperative profile of VAS-based pain sensation (Wilcoxon p = 0.006). None of the secondary endpoints showed any locally significant sample differences.

DISCUSSION:

These results demonstrate a significant pain-alleviating effect of deep oscillation. However, the exact physiological effects underpinning the impact of deep oscillation are still not completely understood.
