TL;DR: Judgements to be made on a patient’s gait pattern at intervals during rehabilitation in order to assess the outcome of the treatment to date and effectively plan the future regime is made.
Abstract: An individual’s walking pattern represents his or her particular solution to the problem of getting from A to B with the minimum expenditure of energy. It is generated through the precise and complex interaction of the many elements of the locomotor system, and under normal circumstances represents a highly efficient form of movement. However, any disorder or disruption of any constituent part of the system will have a deleterious effect on the resulting gait, causing deviations from the normal optimum pattern and making gait less efficient. The restoration of an optimum walking pattern is often a central part of the rehabilitation process. This clearly requires judgements to be made on a patient’s gait pattern at intervals during rehabilitation in order to assess the outcome of the treatment to date and effectively plan the future regime. To do this, clinicians must normally rely on observation of the patient’s gait pattern using

TL;DR: The electromechanical behaviour of the tachographic gait recording system developed by earlier research scientists was analysed and the resulting modified system was used to record the gait of 25 normal, healthy, able-bodied adult males with sedentary habits, and 67 subjects having different types of lower extremity handicap.

TL;DR: A number of gait curves obtained from 16 healthy, able-bodied adult males were selected as "normal" gait curve and thereafter analysed with a view to defining a "Gait Abnormality Index", which may be used as quantitative measure of human performance in locomotion.

TL;DR: This is the first of two papers reviewing where medical engineering methodology might usefully be applied to the routine management of the lower limb amputee.
Abstract: The management of the amputee has recently undergone considerable scrutiny in the United Kingdom.’ The government enquiry which investigated the provision of prostheses for patients highlighted many deficiencies in the way in which this section of the U.K. health service is organised. The report revealed, among other things, a feeling that science had not always been applied to the amputee with success and that prosthetic fitting in particular left much to be desired. Poor prosthetic fit leads inevitably to poor gait and this hampers effective rehabilitation. A prerequisite for the improvement of this situation is therefore an adequate analysis of gait. This is the first of two papers reviewing where medical engineering methodology might usefully be applied to the routine management of the lower limb amputee. The modern gait laboratory relies on three independent disciplines, namely; qualitative observation ; quantitative measurement; and biomechanical analysis. Their combination comprises gait analysis or gait assessment.2 Although a skilled clinician will probably be able to recognise the major improvements in the patient’s walk, minor changes will be much more difficult to de-

TL;DR: The investigation reported in this paper is a follow-up to the authors’ pilot study which was published in an earlier issue of'JMET.
Abstract: A group of 53 adult men, normal subjects as well as victims of different types of lower-extremity handicaps, took part in tachographic gait studies and measurements of physiological energy expenditure whilst walking at a self-selected pace. The observations were analysed to explore the relationships between walking energy expenditure and various gait parameters. This analysis allowed the authors to identify some biomechanical indices which can be used for objective evaluations of human performance in locomotion. The investigation reported in this paper is a follow-up to the authors’ pilot study which was published in an earlier issue of'JMET.

TL;DR: The most recent instrumentation used by the New York University Biomechanics Group in its continuing research in locomotion, “Elgons”, linear and angular accelerometers and circuitry associated with these, are described.
Abstract: WALKING, as the most common method of human locomotion, is analyzed. Characteristic patterns of walking are described. Conventional methods for describing gait in objective terms are discussed and illustrated. These include electrical and optical techniques for obtaining the temporal, kinematic and kinetic measures. The most recent instrumentation used by the New York University Biomechanics Group in its continuing research in locomotion, “Elgons”, linear and angular accelerometers and circuitry associated with these, are described. Analytic methods, vector and harmonic analysis, for the interpretation of the recorded data are presented. The more significant differences between normal and pathological gait are discussed. The application of these techniques to the evaluation of the more complex prosthetic devices are described and other possible applications are also reviewed.

TL;DR: It has been shown that the amputees fitted with PTB prostheses can take up, without any undue extra effort and metabolic cost, industrial occupations of the moderately heavy kind.
Abstract: A below-knee amputee is generally known to achieve a close-to-normal performance level, with the patellar-tendon-bearing method of stump fitting. This was confirmed by an ergonomic investigation on ten below-knee amputees, fitted with PTB prostheses. The test group subjects were given two static tests, two dynamic tests and one exercise tolerance test, during which their oxygen consumptions, pulmonary ventilations, energy expenditures and peak heart rates were measured. The performance of the test subjects were compared with that of a control group consisting of sixteen normal, healthy, individuals. The percentage increases in the values of the biomechanical parameters of the test subjects, over those of the control group, were found to be justified and thus natural to the below-knee amputee-PTB prosthesis system. The ergonomic study has not yielded information regarding the biomechanical efficacy of the PTB prosthesis, but it has also shown that the amputees fitted with such prostheses can take up, without any undue extra effort and metabolic cost, industrial occupations of the moderately heavy kind.
