This article presents the development of a prototype insole derived from natural rubber from Hevea brasiliensis, equipped with pressure control and capable of neoformation of tissue for people who have diabetic foot. The active element of this insole is the electronic circuit that monitors the plantar pressure. In addition, on the present stage of the research, a signal irradiating cell is used based...
It has been well documented that subjects with peripheral neuropathy resulting from diabetes mellitus are at high risk of developing foot ulceration. Decreased sensation, in combination with high underfoot pressures, have been identified as prime etiology factors in the cause of plantar naturopathic ulceration. This study presents the effect of four orthotic treatment techniques in reducing metatarsal...
Walking impairments are a common sequela of neurological injury, severely affecting the quality of life of both adults and children. Gait therapy is the traditional approach to ameliorate the problem by re-training the nervous system and there have been some attempts to mechanize such approach. In this paper, we present a novel device to deliver gait therapy, which, in contrast to previous approaches,...
This paper is a report of the feasibility and outcome of using a low-cost, commercially available gaming system - Wii Fit - for balance training after stroke. The patient was an 86 year-old woman five weeks after stroke, who was unable to walk without close supervision, even with a walker, due to poor balance and a tendency to fall. In addition to standard physical therapy, the patient participated...
The analysis, synthesis and mechanical design of a wearable biomechanical device for treating the club-foot children malformation is presented in this paper. This system serves as non-invasive alternative method for correcting this congenital malformation in 0-1 year-old children. Robot kinematics and constrained Euler-Lagrange dynamics tools are employed to analyse this malformation, altogether with...
A computerized system incorporating a 1024-sensing-site platform has been developed in order to investigate foot-ground pressure distribution in healthy and pathological subjects during posture and gait. Results of clinical experiments carried out on fifteen hemiplegic subjects during rehabilitative procedures involving both static load transfer and one-step walking are discussed. Results are compared...
