Quality and readability of online information on plantar fasciitis and calcaneal spur

Plantar fasciitis and calcaneal spur are common causes of heel pain in the community. People use the Internet to obtain medical information about diseases. We reviewed Internet information sources on plantar fasciitis and calcaneal spur for quality and readability. The first 50 websites for each search term (“calcaneal spur”, “heel spur”, and “plantar fasciitis”) were scanned on www.google.com. Six different valid tools were used for information quality and readability assessment. We searched for HONCode (Health On the Net Foundation Code) stamps on included websites. The total mean points for DISCERN were 50.52 ± 14.62, and the total mean points for JAMA (Journal of the American Medical Association) were 2.42 ± 1.26. In total, 25.72% of 97 websites had HONCode stamps. The average scores for the readability indicators were calculated to be Flesch–Kincaid Grade Level (FKGL): 7.27 ± 1.71, Gunning Fog: 8.46 ± 2.17, Simple Measure of Gobbledygook (SMOG): 6.89 ± 1.24, and Coleman Liau Index: 15.56 ± 1.85. In our study, when the website resources were examined, there were profit websites the most and website quality and readability were moderate level. A significant proportion of the websites have a financial bias and provide low-quality information. A mechanism for monitoring the quality and readability of online information must be established and managed systematically.
