In 2017 the number of diabetics in Indonesia reached 10.3 million people and among them 73.7% were unaware that they had diabetes. The prevalence of diabetes mellitus (DM) in Indonesia has reached 9.1 million people. IDF estimates that the number of diabetics in Indonesia will continue to soar to reach 16.7 million in 2045 (PERKENI, 2015). Increased prevalence of DM patients can increase complications such as heart disease, nephropathy, retinopathy, diabetic foot injury, and neuropathy. Neuropathy is one of the long-term complications that affects about 50% of people with diabetes. Peripheral neuropathy is a broad and potentially disabling pathological condition that includes more than 100 different forms and manifestations of nerve damage. The diverse pathogenesis of peripheral neuropathy affects autonomic, motor and / or sensory neurons, and symptoms that describe these conditions are abnormal skin sensations, muscle dysfunction and, especially, chronic pain (Dobson, McMillan, & Li, 2014). Neuropathy is strongly associated with the duration and severity of hyperglycemia. Disease prevalence increases with increasing duration of DM and poor glycemic control (Chawla, Chawla, & Jaggi, 2016). About 11.9 million adults in the United States aged> 40 years have been diagnosed with diabetes and among them, 3.9 million (32.7%) have diabetes neuropathy and 1.6 million (13.1%) have comorbid neuropathy and retinopathy (Ahmad & Mittal, 2015). https://creativecommons.org/licenses/by/4.0/ https://creativecommons.org/licenses/by/4.0/ mailto:tintin-s@fkp.unair.ac.id.com http://dx.doi.org/10.20473/jn.v14i3(si). JURNAL NERS http://e-journal.unair.ac.id/JNERS | 341 The prevalence of diabetic peripheral neuropathy ranges from 16% to 66%. Amputation in diabetics is 10 to 20 times more common than non-diabetes (Federation, 2017). Patients with diabetic neuropathy are more often hospitalized than other diabetes complications. Diabetic neuropathy increases in patients within 5-10 years after the onset of this disease. Diabetic peripheral neuropathy (DPN) has a strong association with other complications such as diabetic retinopathy (67% versus 21%) and micro albuminuria (51% vs 41%). It has been observed that 56% of patients with DM less than 5 years have moderate / severe DPN (Chawla et al., 2016). As many as 1,785 DM patients in 2008 to 2009 in Indonesia experienced 63.5% of neuropathy complications, 42% diabetic retinopathy, 73% nephropathy, 16% spectacular, and 27.6% microvascular complications (Soewondo et al., 2010). Research in Persadia Units at dr. Soetomo Hospital Surabaya showed that 30.8% of 26 respondents who did not experience diabetes ulcers complained of neuropathy (Widyawati, Irawaty, & Sabri, 2010). One of the factors that trigger diabetic foot ulcers is neuropathy. International Diabetes Federation reports that 1 in 6 diabetics will experience diabetes ulcers during their lifetime (International Diabetes Federation, 2017). Diabetic foot exercises are activities or exercises carried out by DM patients to help blood circulation, especially in the legs or lower leg (Francia, Gulisano, Anichini, & Seghieri, 2014). Based on a preliminary study at the Gedongan Community Health Center in Mojokerto, East Java, DM was included in the list of the 10 biggest diseases in the last 3 years. People with DM every year always experience an increase, in 2015 there were 2,434 patients, in 2016 there were 3,085 patients, in 2017 there were 3,343 patients. In March 2018 there were 32 DM patients with neuropathy. Observations and interviews during preliminary studies with outpatients at the Gedongan Community Health Center with DM showed that 7 out of 12 patients complained of frequent leg pain, calluses, and dry feet. The Gedongan Community Health Center in Mojokerto has not yet intervened specifically in diabetic neuropathy to reduce the incidence of foot ulcers. The intervention given to DM patients is to schedule control patients, health education, and anti- diabetes drugs on a regular basis according to the doctor's advice. Most cases of peripheral neuropathy cannot be fully treated because the underlying cause is unknown or incurable, so the main goal associated with the treatment of most forms of peripheral neuropathy is to control or correct troublesome symptoms (Nathan, 2014). Exercise is known to increase several metabolic factors that can affect nerve health (Nimmo, Leggate, Viana, & King, 2013). Based on previous reviews, researchers were interested in conducting research on the effects of diabetic foot exercise on sensory peripheral neuropathy in DM patients at Gedongan Health Center, Mojokerto City. MATERIALS AND METHODS The research design used was quasy experiment (pre- post test with control design) and the project was approved by the Health Research Ethics Committee of Faculty of Nursing Universitas Airlangga (ethical number 989-KEPK). The sample in this study was DM clients at Gedongan Health Center, Mojokerto. The sample size in this study were 28 clients who were divided into two groups. The sampling technique used in this study was purposive sampling. The instrument used was a 10 g monofilament type type diabetes test Semmes-Weinstein monofilament neuropathy measuring 10 g with a thickness of 5.07 and a checklist for diabetic foot exercises. Retrieval of data in this study was conducted at Gedongan Community Health Center, Mojokerto City, then followed up and routinely intervened through clients' home visits. Samples were divided into treatment groups and the controls were matched pairs. The researcher explained the objectives, benefits, procedures, and research time in detail to the respondents. After that, the researchers asked the respondents for their consent to participate by signing an agreement letter in the study. At the first home visit the researchers conducted a pre test to determine the initial value of the dependent variable by examining the value of sensory neuropathy using a 10 g monofilament device in the treatment and control groups. Foot gymnastics interventions were carried out every 3x / week for 4 weeks, referring to Harmaya (2014) in the treatment group while intervention was not carried out in the control group (Harmaya, Sukawana, & Lestari, 2014). At the end of the fourth week the researchers conducted a post test to determine the final value of the dependent variable, namely the value of sensory peripheral neuropathy with 10 g monofilament in the tre The research analysis was carried out with the help of SPSS v16 software. Bivariate analysis used the Mann Whitney Test statistical test using the degree of significance α ≤ 0.05 to compare the results of the treatment and control groups. The Wilcoxon signed rank statistical test compared the results of the pretest and posttest in the intervention group and the control group. RESULT Most of the respondents were women (71.4%). The majority of respondents were in the range of the early elderly and the late elderly (92.85%); age of 46-55 years (46.43%) and age 56-65 (46.43%). Most of the patients who participated in this study were diagnosed for less than 5 years (39.28%). Most of them do not have job (46.43%). In the treatment group before diabetic foot exercise, the average value of sensory peripheral neuropathy was 2.64, which meant that the DM patients in the treatment group had sensory T. SUKARTINI ET AL. 342 | pISSN: 1858-3598  eISSN: 2502-5791 peripheral neuropathy on average. After diabetic foot exercise, the mean sensory peripheral neuropathy showed a decrease to 1.64, meaning that sensory peripheral neuropathy scores improved. The results of statistical tests showed that there were significant differences between the values of sensory peripheral neuropathy before and after diabetic foot exercise in the intervention group (p = 0,000) while in the control group it meant that there were no differences in sensory peripheral neuropathy (p = 0.564). Whereas in the post-intervention results there were differences in sensory peripheral neuropathy between the treatment and control groups (p = 0.039). DISCUSSION Patients with diabetes and neuropathy are associated with low nerve conduction due to demyelination and loss of large myelin fibers, and decreased potential for nerve action due to loss of axons (Charles et al., 2010; Kobori et al., 2017). In patients with peripheral diabetic neuropathy, loss of sensation in the foot causes recurrent minor injuries (calluses, nails, foot deformities) or external causes (shoes, burns, foreign objects) that are not detected at that time and consequently can cause foot ulceration. This can be followed by ulcer infection, which can eventually cause amputation of the foot, especially in patients with peripheral arterial disease (Alexiadou & Doupis, 2012). In diabetic patients, regular physical activity reduces weight, increases blood glucose control and insulin sensitivity which all lead to a reduced risk of developing neuropathy (Francia et al., 2014). The results of this study indicate that diabetic foot exercise can reduce sensory peripheral neuropathy. Exercise positively influences other pathological factors associated with diabetic peripheral neuropathy, by promoting microvascular function and fat oxidation, by reducing oxidative stress and increasing neurotropic factors (Colberg et al., 2010; Kluding et al., 2012). Exercise-induced Neurotrophin- 3 (NT3) increases are associated with increased peripheral nerve conduction velocity and reduction in neuropathic pain (Li et al., 2012). Neurotrophin-3 (NT-3) is known to promote the survival and differentiation of existing neurons and to encourage the growth of new synapses and neurons. Foot and toes exercises are one of the exercises that can modulate the level of sorbitol in the body so as to prevent a decrease in blood flow in the endoneural blood flow (Dixit, Maiya, & Shastry, 2014). Providing stimulation in the form of exercise or leg exercises can produce potential action resulting in depolarization which results in increased Na + / K + ATP activity, axonal transport is increased, patients feel sensory sensations / sensory responses. Foot exercises can help smooth and improve blood circulation in the legs. It also helps in the process of wound healing in diebetes foot ulcer (Eraydin & Table 1.

In addition to this effect, the main reason for a large increase in blood flow during exercise is a decrease in oxygen in the tissues, which is one of the chemical factors found in diabetic patients. The decrease in oxygen causes dilation because of its direct effect on muscle arterioles. Muscles consume oxygen quickly during exercise, and the amount of oxygen in the tissue decreases. In the absence of oxygen, the arteriolar wall cannot continue to contract, and lack of oxygen causes the release of vasodilators. This causes vasodilation of local arterioles so that all capillaries are open and blood flow increases. Blood circulation that smoothly carries oxygen and nutrients to the tissues and nerve cells that will affect the metabolic process of Schwann cells so that axon function can be maintained. The optimal function of nerve cells in DM patients will maintain sensory function of their feet (Han, Sin, & Yoon, 2013). Foot exercises play a role in controlling blood glucose levels to improve peripheral blood circulation which can be seen from the value of the Ankle Brachial Index (ABI) in DM patients (Barone Gibbs, Dobrosielski, Althouse, & Stewart, 2013). Decreasing glucose levels in the blood will improve myelin nerve function and axons so that DM patients will be able to feel pain, heat, vibration, and pressure. In other words, the nerve endings of patients experience increased conduction and recurrent sensitivity in protection against risky conditions, which are detected by examining the sensation of protection using monofilament 10 g.. CONCLUSION DM patients who perform foot exercises will experience a decrease in the value of peripheral sensory neuropathy because foot exercise movements can improve myelin nerves and axon function so that nerve endings undergo improved conduction and sensitive return detected by monofilament 10 g. There was a decrease in sensory peripheral neuropathy in the intervention group and there was no decrease in the value of sensory peripheral neuropathy in the control group proving the theory above that foot exercise can help smoothen so as to improve blood circulation and sensitivity to prevent numbness. Community health nurses can provide education about foot exercise to DM patients, especially patients with peripheral neuropathy. DM patients are able to do leg exercises independently at home to improve the status of sensory peripheral neuropathy so that it can prevent the occurrence of ulcers.
