Effects of individually optimized rocker midsoles and self-adjusting insoles on plantar pressure in persons with diabetes mellitus and loss of protective sensation
Authors' conclusion
Individualized 3D-printed rockers combined with self-adjusting insoles reduce PP (< 200 kPa) in toes, central and lateral forefoot, but not in heels. Alternative insoles with medial arch support, heel cup and compliant midsole materials might enhance success rate across entire foot.
Study context
- Population
- Persons with DM and loss of protective sensation (LOPS); peak pressure (PP) across seven foot regions; regions with PP ≥ 200 kPa at risk (RaR), PP < 200 kPa not at risk (RnoR)
- Participants
- 21 persons
- Comparison
- Individualized 3D-printed rockers combined with self-adjusting insoles
- Outcome
- Offloading of RaR (PP < 200 kPa) while PP remains < 200 kPa in RnoR

Main finding
As reported in the abstract
PP reduced to < 200 kPa by rockers combined with insoles, by RaR region
Toes, central and lateral forefoot as RaR: PP successfully reduced < 200 kPa in all feet (on average)
24 % - 48 %
Medial forefoot as RaR: feet with PP reduced
68 %
