Callus has been identified as a risk factor leading to severe diabetic foot ulcer; thus, it is necessary to prevent its formation. Callus formation under the first, second, and fifth metatarsal heads (MTHs) is associated with external forces (pressure and shear stress) during walking. However, the gait factors increasing the external forces remain undetermined. Thus, this study aims to identify the factors increasing the external forces to prevent callus formation. In 59 patients with diabetic neuropathy wearing their usual shoes, the external forces, and the lower extremity joint angles were measured using MEMS force sensors and motion sensors. The external forces and their relationship with the lower extremity joint angles and footwear size were determined. Risk factors causing high external forces on the first MTH included small flexion of the knee joint (p = 0.015) and large ankle pronation motion (p = 0.034) to obtain propulsion. For the second MTH, wearing excessively long footwear was identified (p = 0.026). For the fifth MTH, high external force was related to tight width footwear (p = 0.005). An effective intervention for preventing callus formation for the first MTH would involve assisting the push-off foot motion using rocker-sole footwear or gait training. For the second and fifth MTHs, wearing appropriate size footwear would be effective.

Aim. Callus is a risk factor, leading to severe diabetic foot ulcer; thus, prevention of callus formation is important. However, normal stress (pressure) and shear stress associated with callus have not been clarified. Additionally, as new valuables, a shear stress-normal stress (pressure) ratio (SPR) was examined. The purpose was to clarify the external force associated with callus formation in patients with diabetic neuropathy.Methods. The external force of the 1st, 2nd, and 5th metatarsal head (MTH) as callus predilection regions was measured. The SPR was calculated by dividing shear stress by normal stress (pressure), concretely, peak values (SPR-p) and time integral values (SPR-i). The optimal cut-off point was determined.Results. Callus formation region of the 1st and 2nd MTH had high SPR-i rather than noncallus formation region. The cut-off value of the 1st MTH was 0.60 and the 2nd MTH was 0.50. For the 5th MTH, variables pertaining to the external forces could not be determined to be indicators of callus formation because of low accuracy.Conclusions. The callus formation cut-off values of the 1st and 2nd MTH were clarified. In the future, it will be necessary to confirm the effect of using appropriate footwear and gait training on lowering SPR-i.

Diabetic foot ulcer is a preventable complication of diabetes. Nurses must have knowledge related to this condition so that education can be given to patients. This study aims to examine the level of nurses’ knowledge regarding prevention and management of diabetic foot ulcer in Bangladesh. A survey involved 218 nurses working at a national, specialized, and well-established institute of diabetic care of Bangladesh. The Nurses’ Knowledge Regarding Prevention and Management of Diabetic Foot Ulcer Questionnaire (NKPMDFUQ) comprising of 40 questions with 20 true/false questions and 20 multiple choice questions was used. It was content validated and tested for internal consistency and stability yielding acceptable levels of reliability. The findings revealed that nurses had very low level of knowledge (M=52.60%, SD=7.86%). The content areas most nurses did not have knowledge were detecting loss of protective sensation of the feet, caring of callus formation, encouraging patients to have activity of daily living in order to self-manage, setting a goal for prevention of amputation, and giving advice to patients that causes of diabetes is the least important element in diabetic foot care program. The findings are beneficial for establishing training courses. Consequently, quality of care for patients with diabetes will be improved.

Diabetic foot ulcer leads to several problems to the patients. It engenders illness and sometimes deals that. Those wounds lead to nervous problem along with the development of ulcer and amputation which produces high pressure in legs. Perpendicular slope and applied mathematics operation analyzing will be utilized to get foot malformation. The experiential showed a fragile one- dimensionality and an important division in weigh acceptance. Systems can be applied to evade ulceration during the shoe monitoring. Ulceration is the endpoint of the diabetics. The main etiological factors in foot ulceration are diabetic neuropathy and peripheral vascular disease.
