“…Some previous studies have confirmed that customized insoles can be used as an auxiliary physiotherapy tool, which has a positive effect on helping subjects change their gait and re-adjust the pressure distribution on the pelma [14][15][16][17]. Designing customized insoles based on plantar pressure can specifically help users change the abnormally distributed pressure on the plantar, which is one of the most common traditional methods.…”

“…Foot deformity can cause abnormal plantar pressure distribution in individuals with flexible flatfeet, and effective analysis of the plantar pressure in the flatfoot individual's gait cycle can also directly or indirectly understand the condition of the foot deformity [21]. Therefore, the analysis of plantar pressure helps for a better design of customized insoles [16]. This is also a necessary step for insole customization for individuals with flatfeet.…”

Flatfoot is a common musculoskeletal deformity. One of the most effective treatments is to wear individually customized plantar pressure-based insoles to help users change the abnormally distributed pressure on the pelma. However, most previous studies were divided only into several plantar areas without detailed plantar characteristic analysis. In this study, a new insole is designed which redistributes pressure following the analysis of characteristic points of plantar pressure, and practical evaluation during walking of subjects while wearing the insole. In total, 10 subjects with flexible flatfeet have participated in the performance of gait experiments by wearing flat insoles, orthotic insoles, and plantar pressure redistribution insoles (PPRI). The results showed that the stance time of PPRI was significantly lower than that of the flat insoles under slow gait. PPRI in the second to third metatarsal and medial heel area showed better unloading capabilities than orthotic insoles. In the metatarsal and heel area, the PPRI also had its advantage in percentage of contact area compared to flat insole and orthotic insole. The results prove that PPRI improves the plantar pressure distribution and gait efficiency of adults with flexible flatfeet, and can be applied into clinical application.

“…Of note in this analysis is that they compared the significant differences across DNPAD, DPN, and DNN. This represents the progressive nature of chronic diabetes complications and may indicate a higher risk of biomechanically induced higher plantar pressure, leading to ulceration as the severity progresses 5,16 . Importantly, the results of this study support emerging research identifying risk factors in DFU, indicating that diabetic foot syndrome may play an essential role in changing plantar pressure patterns…”

INTRODUCTION: The prevalence of diabetic foot syndrome is increasing in the Indian population. It is a triad of neurological, vascular, and biomechanical changes due to long term diabetes mellitus (DM). Altered plantar pressure distribution is a risk factor for developing diabetic foot ulcers. The purpose of this study is to evaluate the altered plantar pressure distribution in diabetic peripheral neuropathy individuals with peripheral vascular disease in comparison with diabetic peripheral neuropathy and non-diabetic neuropathy. Therefore, the objective of the study is to evaluate the plantar pressure distribution and parameters in type 2 DM (T2DM) with diabetic foot syndrome.METHODS: In this study, 60 participants with T2DM were recruited in either one of the three groups: 20 Diabetic non-neuropathy (DNN), 20 Diabetic peripheral neuropathy (DPN), and 20 Diabetic peripheral neuropathy with the peripheral arterial disease (DNPAD). Then we compared the plantar pressure parameters like maximum plantar pressure, pressure-time integral, fore foot-hind foot ratio, and total contact area were measured using a WinTrack plantar pressure system.RESULTS: The diabetic peripheral neuropathy with peripheral vascular disease group shown a significant difference in all the plantar pressure parameters measured in comparison with the diabetic peripheral neuropathy group. There was increased Maximum plantar pressure, pressure-time integral and forefoot hindfoot ratio, and reduced total contact area of the foot (p < 0.05).CONCLUSION: For patients, with combined peripheral neuropathy and peripheral vascular disease have increased plantar pressure distribution, are at higher risks of developing neuro-ischemic foot, which further leads to diabetic foot ulcers.

“…Recent systematic reviews pointed out that suitable insole hardness significantly decreases the peak plantar pressure (PPP) as well as decreases the risk of developing diabetic foot ulcers (DFUs) 11,12 . An insole with proper hardness transfers high forces from the foot's bony areas to nearby foot regions, significantly reducing 40% PPP and enhancing patient comfort 13 .…”

Air insoles may be applied to improve peak pressure gradient (PPG) and plantar gradient angle (PGA) for reducing foot ulcers risk in Diabetes mellitus. Dynamic PPG and PGA distributions of air insoles are uncertain. This study investigated the effects of different air insoles on the PPG and PGA. A repeated measures study design, including three air insoles and two walking durations was tested in 13 healthy participants. PPG and PGA values at plantar region of the big toe (T1), first (M1) and second (M2) metatarsal head were calculated. The PPG was lower at 80 mmHg air insoles after walking 20 min in the M1. The PGA in the M2 increased at an air insole of 80 mmHg compared to 240 mmHg. At 240 mmHg of air insole, the 10 min walking had the lowest PPG in M1 and M2. Moreover, peak plantar pressure (PPP) correlated positively with PPG for all air insoles. PPP and PGA were negatively correlated with 80 mmHg air insoles after 20 min of walking. 80 mmHg air insole lowered the PPG, decreased PPP and increased PGA compared to 160 and 240 mmHg. A shorter walking duration lowered the PPG. Air insoles might decrease foot ulcers risk by concerning PPG and PGA.
