“…However, if the arch support portion is too prominent, it may induce excessive localized pressure over the plantar arch and lead to discomfort. Previous research indicates that custom-molded orthosis with some modifications were more effective in the management of plantar pressure than the custom-molded orthosis alone without modifications [15][16]. In this study, we noted significant differences in pressure distribution between the three contoured insoles, which illustrated that an insole made of different casting conditions could provide different pressure redistribution function.…”

“…Since the foot shape is changed with loading [11][12][13][14], the benefit provided by the insole cast with different weight-bearing conditions may vary. We found that modifications of a custom-molded insole cast from an unloaded plantar shape were more effective for pressure relief [15][16]. This finding suggests that a custommolded insole from an unloaded foot may not be the best shape to properly fit the flexible feet.…”

“…Previous studies examined the effects of insole type and material on pressure redistribution, but few dealt specifically with the comparison of insole shapes cast under different loading conditions. Soft flat insoles have been found to reduce plantar pressure and increase contact area [23][24][25], but they were found less effective than the contoured insoles [15,22,[26][27]]. In the current study, soft flat insoles were found to reduce the mean peak pressure and to maximize contact area in the whole foot region, but significant change occurred in the PTI for all foot regions from the shoe-only condition.…”

“…Kato et al demonstrated that the use of custommolded polyurethane insole could provide a mean reduction of peak pressure of the whole foot by 56.3 percent, and increase the peak contact area by 62.7 percent [15]. Albert and Rinoie reported that custom-molded foot orthoses could reduce the peak plantar pressure by 30-40 percent and increase total contact area by 5-10 percent [26].…”

Abstract-For this study, we compared the effectiveness of different design insoles for redistributing pressure during walking for diabetic patients and for normal control subjects. Comparisons of dynamic plantar foot pressure patterns were made with different support, including shoe-only, flat insole, and three contoured insoles. We custom-molded the three contoured insoles by casting the plantar surface of the foot under the conditions of non-weight-bearing, semi-weight-bearing, and fullweight-bearing. With the F-Scan in-shoe system, the interfacial pressure distribution during walking with different plantar supports was measured at 50 Hz for 10 s. The use of insoles could significantly reduce local peak pressure and pressure-time integral and increase the contact area. Contoured insoles were significantly better than flat insoles with regard to the insole functions in reducing local peak pressures. The insole with the semi-weight-bearing foot shape can offer the greatest peak pressure reduction compared to other insole designs, especially for patients with peak pressure located at the second to third metatarsal heads.

“…Of the studies reviewed, 4 articles discussed the ankle orthosis on reducing plantar pressure, where a study was prepost [35], 1 report [36] and 2 RCT [34,37]. There is little research regarding use of ankle orthosis in reducing the plantar pressure and also available articles were not valid regarding their results.…”

Purpose: Today considering the high prevalence of diabetes and its associated pressure ulcers, also irreparable consequences such as amputation and death, the use of orthotic devices is increasing. A variety of devices have designed to prevent ulcers in the patients' feet, however other aspects of the treatment, especially the performance of these patients in standing and walking, which are their main daily activities, have not been considered in designing and use of orthotic devices. In addition, the differences between the available devices and their effects have not been described yet. Therefore the aim of this review article is to answer these issues. Methods:A comprehensive research was done in databases of PubMed, Google Scholar, and ISI Web of Knowledge. The keywords such as "diabetic neuropathy", "orthosis", "plantar pressure", "balance", "energy consumption", and "spatial-temporal parameters of gait" and their results were analyzed. The quality of articles were evaluated by Downs and Black tool.Results: After proper search, 245 English articles were found with the related keywords. Then, 184 articles were excluded because of a common title or incomplete text. Also, 25 articles were excluded from the study, because their contents did not relate highly to this study or have reasonable conclusion based on the findings of other articles. Eventually the results of 36 articles were examined and reported. Conclusion:This study has examined the various articles from randomized control trial to case report. Most studies emphasized on the reduction of plantar pressures and ulcer treatment with orthotic devices. A few studies are available on the effects of orthosis in standing balance and walking parameters. However, no study was found with regard to the effect of orthotic treatments on energy consumption in these patients. Because this topic is very important, it is suggested that future studies be focused on these issues.

Monitoring body motion is relevant to motor control disorders as well as assessment of fine motor skills in child development. Furthermore, motion tracking is necessary for rehabilitation monitoring and injury prevention and benefits both sick and healthy individuals. Flexible pressure sensors based on resistors, capacitors, inductors, or transistors are reviewed in the context of healthcare measurements, ranging from physiological signals to body movement characteristics such as grip and gait. To demonstrate the use of flexible pressure sensors for motor assessment, a touch sensing glove that evaluates fine motor skills in autism research is developed. The results show that autistic children perform fewer taps per minute compared to typically developing children, with larger variations in tap durations. In a second example, a force and motion sensing glove is developed to assess spasticity, a neuromuscular disorder that causes muscle stiffness/resistance and jerky movement. Analyses of force versus velocity show movement-dependent muscle resistance in a patient with spasticity. Through these flexible sensor systems, the shift from subjective scores to objective measurement will promote better diagnosis and dramatically improve the accuracy in tracking patient response to therapy.patients doing certain movements, and then clinicians rank each patient's level according to qualitative descriptions in benchmark classification scales. [12,13] The subjective scores can be inconsistent between raters and do not capture finelevel changes in a patient's progress in response to therapy. Therefore, there is a critical need to tackle the issue of imprecise assessment of motor disorders.With recent advances in flexible sensors and innovations in tactile sensing, [14][15][16][17][18][19] we have new low-cost technologies that are prime to facilitate quantitative evaluation of motor control. This progress report presents current developments in wearable sensor systems applicable to motor disorders, so that consistent, objective metrics become available to accurately track whether a treatment effectively relieves symptoms. The wearable sensors are not limited to placement on patients but can also be worn by clinicians or caregivers to assist them in taking measurements during patient interactions. [20,21] The point-of-care sensor systems will allow frequent monitoring, which is highly desirable to offer a better understanding of the patient's short and long-term response to therapies, to tailor treatment and improve outcome and quality of life for patients.Other reviews [14][15][16][17][18][19] have already extensively covered the flexible materials and devices used in tracking vital signs and electronic skin applications. In light of that, this progress report focuses on the applications in monitoring motor skills, in particular to implement pressure sensor designs for wearable systems with diverse form factors, for instance, gloves, [20,22,23] epidermal tags tags, [24,25] and shoe insoles. [26,27] We will discuss the mechanis...
