Subcalcaneal pain, a clinical syndrome is the common foot problem in middle-aged persons. Many possible causes and treatment have been discussed. However it is not clean exact cause of the pain because of complexity of mechanism of subcalcaneal pain. Some authors suggest that the certain abnormal plantar fascial tension created by biomechanical factors(such as flat foot, limited subtalar motion, tight Achilles tendon etc.) may be occurring symptoms.

The calcaneal pitch is the simple method to measure the flat foot(reduction of medial longitudinal arch). Comparison the mean calcaneal pitch in 12 subcalcaneal pain patients with 20 normal subjects revealed no statistical differences. And also body weight using body mass index(BMI) compared in this two groups. There was significant statistical differences in subcalcaneal pain patients. The incidence of calcaneal spur and overweight were significantly higher in subcalcaneal pain patients than in normal subjects.

As a conclusion, there is no direct relationship of subcalcaneal pain and reduced calcaneal pitch, however body weight may be important factors to develop subcalcaneal pain and heel spur formation. I think that a correct evaluation of subcalcaneal pain must be based on the anatomic and mechanical factors that produce the abnormality.
