That is the significant problem as to why there is no complete cure for diabetes yet. Current treatments for diabetes are only to check the amount of glucose in the blood, adjust the food, and keep exercise activities every day by oneself [1; 3]. Walking is the activity recommended for most diabetic patients, while being effective in weight loss and maintenance and in improving glucose control [4]. This recommendation comes from the results of a meta-analysis, including many small, short-term randomized controlled clinical trials (RCTs) and some recent additional research, showing clinically appreciable improvement of HbA1c [5; 6]. The effect on insulin resistance is not apparent. Walking is easily applicable in daily life in most patients without requiring expertise, and logistic support can be performed in different places [7; 8]. Limited information indicates the improvement of several alterations involved in the increased cardiovascular risk associated with diabetes. Moreover, a small study reported favorable changes in several functional aspects of diabetic neuropathy, although the presence of this condition requires specific monitoring of patients and may also limit walking activities [4]. Many researchers have shown that elders with diabetes were related to a greater risk of falls, and this was more clear in insulin-treated patients [9]. For example, according to six studies involving 14,685 participants, the number of falls in diabetic and non-diabetic, respectively, was 25.0%, and 18.2% [10]. On the other hand, diabetes increased 94%, and 27% risk of falls in insulin-treated and no-insulin-treated patients, respectively [11]. Hence, preliminary screening before starting any physical activity programs in older adults with diabetes mellitus should include a general medical examination, with specific attention to symptoms and signs of chronic complications (cardiovascular disease, nephropathy, retinopathy, and neuropathy), and assessment of metabolic control [12]. However, the significant problem is that there are large changes in the analysis results due to the diverseness of the diabetic population with the presence and severity of diabetes complications. Accordingly, although the prescription of walking in patients with diabetes should be preceded by a tailored medical and functional assessment, it is difficult to assess the functionality of walking capacity by themselves [13]. Thus, senior citizens with diabetes must recognize the diabetic walking abnormality for self-preservation and evaluate the functionality without expert medical knowledge using the simple sensing system. The results of several studies have been conducted to assess walking biomechanics alterations in diabetic neuropathic subjects [11]. According to kinetics and muscle activation patterns, there have been significant variations in the results of both a reduction and an increase in the gastrocnemius activity and the lower limb joints moments. In terms of plantar pressure [14; 15], a shorter center of pressure (CoP) excursion and a higher peak pressure over the forefoot have been found [16]. Although the diabetic symptoms are apparent, the neuromuscular, kinematics, and kinetics changes do not show a distinct pattern associated with the results of diabetes and diabetic neuropathy (DPN) [17; 18; 19; 20; 21; 22; 23]. Compared to these analyses of movement symmetry, continuous relative phase (CRP) is one of the most sensitive analyses for detecting the mutual relationship among the joints and asymmetries in coordination during walking, particularly for identifying cyclic movement deviations caused by diabetes [24; 25]. However, because CRP also tries to explain biomechanical walking patterns, such as ground reaction forces, angles, and moments of the trunk, hip, knee, and ankle, the assessment should be performed at the well-equipped hospital with expert medical knowledge by using the expensive motion capture system. Thus, it seems complicated to protect diabetic senior citizens by themselves in daily life through conventional works.
