Effectiveness of customized insoles on maximum plantar pressure in diabetic foot syndrome: A systematic review.

BACKGROUND AND AIMS

Diabetic foot syndrome is a severe complication of type 2 diabetes mellitus with diabetic peripheral neuropathy. Increased maximum plantar pressure is a strong predictor that may be detrimental and cause a plantar ulcer. This present systematic review aims to evaluate the effectiveness of customized insoles on reducing maximum plantar pressure in diabetic foot syndrome.

METHODS

We conducted a systematic review (PubMed, Cochrane Database of Systematic Reviews, CINAHL, Pedro, Scopus) to summarize the evidence on the customized insole on maximum plantar pressure in diabetic foot syndrome. Randomized and non-randomized studies were included in the review. The quality of the included studies was assessed independently by the two review authors with the Modified Downs and Black checklist for the assessment of the methodological quality of both randomized and non-randomized studies.

RESULTS

A total of 1512 studies screened. After the exclusion criteria, 5 studies were included in the study. The outcome measure that was considered is maximum plantar pressure and pressure-time integral.

CONCLUSIONS

We concluded that the practice of customized insoles could significantly reduce maximum plantar pressure. While developing an insole, parameters like contoured insoles with shape and pressure based, weight-bearing position, and duration with good adherence to footwear application can significantly reduce maximum plantar pressure.
