A link between diabetes, PF, and peripheral neuropathyPosted by Sharon W on 5/05/03 at 10:00 (117828)
I was quite interested to see this abstract for a study of PF clinical signs in people who have diabetes (and in many cases, also perpheral neuropathy). Some of these diabetic patients seemed to be developing PF. It showed that soft tissue involvement may lead to increased changes in the structure of plantar fascia (possibly including an increase in its thickness) and could affect the mobility of the first metatarso-phalangeal joint due to the increase of vertical forces under the metatarsal heads.
The researchers were concerned that the extra pressure this puts on the bottom of the foot can cause foot ulcers in these diabetic patients (and of course, for diabetics, foot ulcers can sometimes lead to amputation...)
I found it in the Diabetes Care website:
'Secondary to peripheral neuropathy, plantar hyperpressure is a proven risk factor for foot ulceration. But limited joint mobility (LJM) and soft tissue abnormalities may also contribute. The aim of this study was to evaluate the relationships among thickness of plantar fascia, mobility of the metatarso-phalangeal joint, and forces expressed under the metatarsal heads.'
'Diabetic patients presented increased thickness of plantar fascia... and significantly reduced motion range at the metatarso-phalangeal joint... The evaluation of foot-floor interaction under the metatarsal heads showed increased vertical forces in DN [diabetic neuropathy] and DNPU [people with diabetic neuropathy and ulcers on the bottom of their feet] and increased medio-lateral forces in DNPU. An inverse correlation was found between the thickness of plantar fascia and metatarso-phalangeal joint mobility...'
