Validity and Reliability of a Vibration-Based Cell Phone in Detecting Peripheral Neuropathy among Patients with a Risk of Diabetic Foot Ulcer.

The aim of this study was to determine the validity and reliability of a vibration-based cell phone in detecting peripheral neuropathy among individuals with a risk of diabetic foot ulcer (DFU). The current study consisted of 3 phases: a pilot study, concurrent validity study, and interreliability study. A 128 Hz tuning fork and vibration-based cell phone using the Vibrations-Test app was compared in the primary care setting. The pilot study confirmed that the vibration-based cell phone has an adequate reliability (r > 0.70, P < .001). The concurrent validity test involved 96 participants (aged 55.78 ± 8.32 years). The Pearson correlation test found the highest correlation in the fifth metatarsal heads (r = 0.741, right feet; 0.772, left feet; P < .001). In the 4 primary care settings, the interrater reliability between nurses of the vibration-based cell phone were k = 1.000, 1.000, 1.000, and 0.720. The concurrent validity test found moderate to strong correlation results and that the interrater reliability had a strong agreement that was almost perfect. Thus, vibration-based cell phone applications can be used as screening tools for detecting neuropathy among individuals with a risk of DFU.

Development and evaluation educational videos of diabetic foot care in traditional languages to enhance knowledge of patients diagnosed with diabetes and risk for diabetic foot ulcers.

AIM: This study aimed to develop an educational video for diabetic foot care in the traditional languages (Buginese and Makassarese) and evaluate the change in the patients' knowledge level after they viewed the video. METHODS: The study was performed in the following three phases: development of the video content using a Delphi Study that involved wound-care nurses, evaluation of the video's content validity by the expert panel, and evaluation of the video in the community setting by showing it to patients who spoke the traditional languages, were diagnosed with diabetes mellitus (DM), and were at risk of diabetic foot ulcers (DFU). RESULTS: Five themes emerged from the Delphi study, including observation of pre-ulcer signs, washing feet, cutting toenails, wearing socks, and checking footwear. Content validity evaluation recommended these items to be constructed for video education using the traditional languages. Evaluation in the community setting confirmed that there was a significant improvement (p = 0.001) in the knowledge about foot care among patients diagnosed with diabetes and at risk of DFU. CONCLUSION: This study produced an educational video that used the trans-cultural approach by using traditional languages to overcome the communication barrier in the process of knowledge transfer. We found that the educational video in traditional languages enhanced the patients' knowledge about diabetic foot care and thus could enable them to detect the risks for DFU and prevent DFU.
