Plantar pressure relief using a forefoot offloading shoe

Abstract

To assess the effectiveness of the Barouk(®) second-generation postoperative forefoot relief shoes during appropriate use of the shoe on healthy subjects. A convenience sample of 35 volunteer subjects (17 women, 18 men) was recruited to participate in this study. Dynamic foot loading was evaluated with inshoe plantar pressure measurements. Subjects were asked to walk two trials at a self-selected speed: (a) in their mass-produced shoes to assess baseline pressure values, defined as 100% and (b) with the Barouk(®) postoperative shoe on the right foot and their own shoe on the left side. Data analysis was tested for statistical differences with paired Student's t-tests (with p<0.05 as a significance level). The Barouk(®) second-generation postoperative forefoot relief shoes relieved forefoot pressure in all trials. For all 35 volunteers, there was a 79-96% mean peak pressure reduction (p<0.001) of the forefoot except for the fifth metatarsal head during appropriate use of the postoperative shoe. In contrast to the results for the forefoot, a significant increase of the peak pressure values was observed in the heel region. Similar findings were observed for the pressure-time integral values. The data of our study provide evidence that the second-generation Barouk(®) shoe relieve pressure of the forefoot with appropriate use.
