Abstract
Objective
To assess the influence of diabetic neuropathy (DN) on balance and functional strength in patients with diabetes mellitus type 2 (DM2).

Design
Cross-sectional study.

Setting
Diabetes outpatient unit.

Participants
Adults (N=62; age range, 40–65y): 32 with DM2 (19 subjects without DN and 13 with DN) and 30 without DM2 (control group).

Interventions
Not applicable.

Main Outcome Measures
Upright balance, evaluated in 4 situations (fixed platform, unstable platform, with eyes open, with eyes closed), and functional strength, assessed with a five-times-sit-to-stand test, were analyzed using an electromagnetic system, with a sensor placed over C7 to allow maximum trunk displacements in the anterior-posterior and medial-lateral directions. The Berg Balance Scale and the Timed Up & Go test were also used.

Results
Subjects with DM2 had greater anterior-posterior displacement (P<.05) in the unstable platform with eyes closed condition compared with those without DM2, whereas no difference in medial-lateral displacement was observed between these groups. A difference in time was observed in the five-times-sit-to-stand test (P<.05), with subjects in the control group performing the tasks faster than either group of subjects with DM2. Additionally, subjects in the control group showed a higher score in the Berg Balance Scale and performed the Timed Up & Go test in less time compared with subjects in other groups.

Conclusions
Subjects with DM2, with or without DN, showed deficits in postural control and functional strength compared with healthy individuals of the same age group.
