Background

Motor skills deteriorates with aging. Some conditions may magnify this deterioration. This study examined whether diabetes and hemodialysis (HD) would negatively impact gait, balance, and physical frailty beyond aging.

Methods

Seventy-three elderly adults with diabetes (age=71.4±5.4 years, BMI=30.8±5.9, 49% were on HD) and seventy-eight mid-age adults with diabetes (age=56.7±5.7 years, BMI=31.1±7.2, 50% were on HD) were recruited. Gait and balance performances were objectively measured using validated wearable sensors at HD clinic. Frailty status was determined by Fried Frailty Criteria.

Results

Aging deteriorated motor-functions (gait and balance) in people with diabetes irrespective of dialysis (9%-46% deterioration, Cohen’s deffect size=0.22-0.42),with largest effect size observed for double support in gait performance (p=0.011).In addition, deteriorations in gait and balance caused by aging were more pronounced among diabetics with HD (19%-65% deterioration, d=0.41-0.75, p<0.05), when compared to diabetics without HD (1%-14% deterioration, d=0.01-0.20, p>0.05). The largest effect size for gait deterioration among diabetics with HD was observed in double support test (d=0.75,p = 0.002, Fig. 1), and the largest effect size for balance deterioration was observed in ankle stability test (d=0.48, p = 0.042, Fig. 1). Diabetics with HD, irrespective of age, had 3 times higher prevalence of frailty than diabetics without HD (42% vs. 14%, p=0.017).

Conclusion

Our study showed that HD deteriorates gait and balance and magnifies prevalence of frailty by factor of 3 beyond aging in people with diabetes. Immobility caused by prolonged HD (4-hour, 3 times per week) and post-dialysis exhaustion may contribute to poorer motor function in older diabetics leading to frailty. This study demonstrated practicality of wearable sensors to assess motor performance in dialysis clinics with opportunity to capture early deterioration.
