Abstract Background Evidence for wearable-guided physiotherapy in diabetic kidney disease (DKD) is limited. This study evaluated the effects of physiotherapist-supervised exercise supported by wearable device feedback in patients with type 2 diabetes, including those with DKD. Methods In this single-center, prospective study, 58 outpatients were allocated to an intervention group (IG) or non-intervention group (NIG). The per-protocol set included 45 participants completing six months (IG = 25, NIG = 20). IG wore a wrist-worn device and received monthly physiotherapist-led guidance; NIG received standard care. The primary endpoint was 6-min walk distance (6MWD); secondary outcomes included weight-bearing index (WBI), phase angle (PhA), HbA1c, and eGFR. Analyses used linear mixed-effects models adjusted for covariates. Results IG improved 6MWD from 512.0 m to 551.0 m (+ 38.7 m), while NIG changed from 410.0 m to 407.0 m (− 3.7 m). The group × time interaction was significant ( p < 0.001); adjusted between-group difference was + 42.4 m (95% CI: 20.3–64.5). IG showed greater reductions in HbA1c (− 0.89%, 95% CI: − 1.53 to − 0.25; p = 0.008) and improvements in WBI and PhA ( p < 0.01). Changes in eGFR were not significant (0.65 mL/min/1.73m 2 , 95% CI: -3.84 to 5.14; p = 0.78). Conclusions Monthly physiotherapist-led exercise supported by wearable feedback improved functional capacity and glycemic control in patients with DKD. This pragmatic, scalable model may enhance outpatient rehabilitation strategies. Graphical abstract Values represent adjusted between-group differences in change from baseline to six months, estimated using linear mixed-effects models with group, time, and group × time interaction, adjusted for age, baseline 6-min walk distance, HbA1c, eGFR, cardiovascular disease, and smoking status. Error ranges indicate 95% confidence intervals. Arrows indicate direction of change favoring the intervention group.
