Gait characteristics in people with type 2 diabetes mellitus

Abstract

Sixteen control subjects and 15 subjects with type 2 diabetes were examined to compare gait characteristics during walking in a linear path and in turns of 0.33 and 0.66 m diameter. Subjects were excluded if there was diminished sensation in the feet or impairment of strength in the legs. This was done to isolate the effect of diabetes gait independent of loss of sensation. Gait was assessed through contact sensors on the foot, video, and two axis accelerometers mounted bilaterally on the head, shoulders, hips, knees and ankles. The results of these experiments showed that subjects with diabetes walked significantly slower (P<0.05) than control subjects and with a wider stance (P<0.01), both for walking in a linear path (velocity of subjects with diabetes was 62.2% that of controls and stance was 134.9% wider than controls) and when making turns (velocity 50.6% of controls and stance 120.1% wider than that of controls). Accelerometry showed increased flexion/extension and lateral movement of the major joints in subjects with diabetes during both walking in a linear path and turns compared to control subjects. Part of the increased movement at the joints in the subjects with diabetes was due to tremor in both the 8 Hz and 16 Hz bands. These findings suggest that at least some of the increased joint movement during walking in people with diabetes is likely neurological in origin and not related to muscle weakness or loss of sensation in the feet.

Indicators of Future Ulceration in Diabetes Patients of Low-Moderate Foot Risk

“…When discussed in relation to neuropathic patients it is suggested that the differences are due to proprioception deficits, this is something to consider for this low-moderate risk cohort. Studies have previously reported the biomechanical walking properties of DM patients with peripheral neuropathy to be similar to elderly population gait patterns [18,45,46]. Step Length (metres) ** 0.6 ± 0.1 0.…”

Effects of Eccentric and Concentric Exercises on Some Functional Activity Indexes of Patients With Diabetes Type 2

“…While concentric exercises were performed as running on treadmill with ramp slop controlled for + 4°. For both of the groups understudy the exercises were performed in 70% to 75% of maximum heartbeat for 20 minutes (adding five minutes to warm the body and five minutes to get cold) (28). Considering the recommendation of American Diabetes Association, the maximum heartbeat increase for the functional activities in patients with diabetes should be between 60% and 79% (29).…”

Análise do equilíbrio postural de indivíduos diabéticos por meio de baropodometria

“…Ferreira, C.E. Fregonesi A neuropatia, evidenciada no presente estudo, desencadeia um comprometimento progressivo na estrutura nervosa periférica, inicialmente aferente e posteriormente motor, gerando denervação de distal para proximal (Petrofsky, Lee, & Bweir, 2005), sendo evidenciado por alguns autores déficits neurais (tibial, sural e plantar medial) ( Richardson, Ching, & Hurvitz, 1992) e musculares (tibial anterior, gastrocnêmico e fibular) (Sacco & Amadio, 2003). Os resultados deste estudo apontam redução da força muscular isométrica dos plantiflexores e dorsiflexores do tornozelo de indiví-duos com neuropatia diabética.…”
