Parameters for analysis of walking foot pressures at different levels of diabetic neuropathy and detection of plantar ulcers at early stages

Optical Pedobarography for Assessing Neuropathic Feet in Diabetic Patients—A Review

“…Studies [5][6][7][8][9][10]13 have defined peak foot pressures and loss of protective sensation as the cause for plantar ulcers in diabetic neuropathy. These investigations did not define the ulcer risk threshold completely; indeed, diabetic patients may develop ulcers at pressures that are "normal."…”

“…In later studies, Prabhu 10 quantified loss of sensation into 3 levels (using the criteria proposed by Bell-Krotoski 17 ) and reported good correlations between quantified levels of sensation loss and mean values of normalized foot pressure parameters (NPP and PCR). However, when the standard deviations were taken into account, they were not sensitive to the early stages of neuropathy causing plantar ulcers.…”

“…The above principle was 1st used by Chodera, 1 then by Betts, 2,3 Franks, 4 Boulton, 5 Veves, 6,7 Patil, 8,9 and Prabhu [10][11][12] for obtaining foot pressure images during standing or walking. Patil 8,9 and Prabhu et al [10][11][12] designed a longer optical pedobarograph to accommodate both feet. These workers also developed online analy-sis of foot pressures on both the feet in standing and in succession during walking.…”

“…Patil et al 8,9 and Prabhu et al [10][11][12] used a longer optical pedobarograph that could accommodate both feet and that facilitated analysis of foot pressures on standing and while walking. The technical aspects of this method are discussed in a succeeding section and presented pictorially in Figure 1.…”

“…Potrebe na području ortopedskih uložaka sve su veće. Medicinska svrha ovih plantarnih proteza je ispraviti držanje ili biomehaničku neravnotežu koja ima tendenciju uzrokovati bol u različitim područjima tijela ovisno o patologiji pacijenta [7] [8][9] [10]. Terapeutske indikacije, koje se najčešće preporučuju, pronalaze se u slučaju osteoartritisa koljena ili bokova, nogu, nejednake dužine, kavusnog (visoki svod) i ravnog stopala (niski svod) ili zoni visokog tlaka [11] [12].…”
