Diabetic ulcers can lead to infection and amputation. Using insole can help to reduce and prevent foot ulceration and amputation in a diabetic patient. The aim of this study was to analyze the effect of wearing an insole with different density on standing and walking plantar pressure distribution. Methods: A group of 10 diabetic patients participated in this one-grouped before-after trial. Plantar pressure distribution was measured during walking and standing. Repeated Measure was used to test differences. Results: Repeated measure test showed that use of insole decreased foot pressure while walking significantly ([Formula: see text]). Pairwise comparison showed that wearing shoe insole with shore 30 decreased pressure compared to wearing shoe insole with shore 50 ([Formula: see text]) and walking without insole respectively ([Formula: see text]). Conclusion: The insole has more effect on plantar pressure during walking than standing, it also concluded that insole with shore 30 decreased pressure during walking more than that of the insole with shore 50. It could be said that patients who suffer from pain and discomfort on hind and forefoot may benefit insole with shore 30 to relieve from plantar pressure on the hindfoot and forefoot regions during standing and walking.
Purpose: This study aimed to assess the effect of Boston brace on trunk muscles length as well as lower limbs and trunk range of motion in patients with idiopathic scoliosis.
Methods:Five patients with idiopathic scoliosis with C shape curve and mean (SD) age, height, and weight of respectively 12.61(1.16) years, 1.53(0.08) m, and 35.6(6.1) kg participated in this study. Spatiotemporal parameters, range of motion of lower limbs and trunk, and muscle fiber length of erector spinae, internal and external oblique are the variables of this study. Qualysis motion analysis system and Kistler force plate was used to obtain and record raw data. Also, we used QTM and OpenSIM software to extract data. Statistics analysis was done by SPSS ver. 22 at the significance of 0.05.
Results:Based on the results, trunk range of motion in sagittal plane decreased significantly (P=0.02), while pelvis range of motion in frontal plane increased significantly (P=0.006) during walking with brace. The changes in erector spinae and external oblique muscle fibers length were small and not significant (P>0.05).
Conclusion:Walking with brace decreases trunk range of motion in sagittal plane that can lead to change in erector spinae and external oblique muscles length. Thus, it is recommended that flexibility and rehabilitation of these muscles be considered. More studies are needed to assess these muscles weakness after a long time use of the brace.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
