Efficacy Of An Antigravity Treadmill On Functional Outcome In Non-Operatively Treated Pelvic Fractures: A Prospective Pilot Study

Background/Aims Treating pelvic fractures non-operatively is possible. The immobilisation stage of recovery requires different adjustment processes compared to those used in operative treatment. The aim of the present study was to prove the additional benefit an antigravity treadmill can have on patients with non-operatively treated pelvic fractures.Methods A prospective pilot study, including patients with non-operatively treated pelvic fractures as the intervention group and healthy volunteers as a control group, was undertaken. Patients of the intervention group participated in a training session with an antigravity treadmill every 3 days for a total of 40 days, in addition to physiotherapy, lymph drainage massage and manual therapy. Patients were evaluated using a dynamic gait index, and a numeric rating scale on three successive dates, to assess their pain. A standardised gait analysis was also carried out.Results The intervention group comprised 9 patients, while 33 patients made up the control group. All patients completed the protocols and experienced a significant decrease in pain and increase of mobility. Gait analysis showed that by the 40-day follow-up, patients in the intervention group had regained almost normal gait patterns when compared to the control group. At each time point, a significant improvement in patients' gait patterns could be seen.Conclusions The results concurred with previous studies, suggesting that the antigravity treadmill is safe and that recovery to almost normal gait patterns is possible, while the comparison to a healthy group strengthened the data. The present prospective study thus showed promising results regarding the efficacy of the antigravity treadmill, despite study limitations.
