Despite this wide utilization, very little is known about the biomechanical stresses sustained by the upper extremities when using these devices. The objective of this short chapter is to present a methodology used to quantify upper extremity joint loads during ambulation with a conventional walker. Data for a standard walking condition are also provided. The authors believe that this technology and knowledge will prove useful to improve the methods of use and the design of walkers. While the authors present data collected in an adult population, this technology can easily be transferred to the pediatric population.","PeriodicalId":343260,"journal":{"name":"Pediatric Gait: A New Millennium in Clinical Care and Motion Analysis Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129066853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concern has been raised that lengthening muscles could exacerbate this weakness.

Push-off power generation at the ankle increased rather than decreased. Appropriate lengthening of the gastrocnemius/soleus muscle can result in an increase in pushoff power as measured by gait analysis.","PeriodicalId":343260,"journal":{"name":"Pediatric Gait: A New Millennium in Clinical Care and Motion Analysis Technology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115784617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work was to provide a quantitative pilot comparison of ambulation with anterior and posterior walkers in children with cerebral palsy using temporal-spatial gait parameters and an upper extremity joint kinetics. Following informed consent, data were collected for nine children with spastic, diplegic cerebral palsy who were community ambulators and who routinely used posterior walkers. Results of the study showed increased double limb support time (24.3%-30.7%) with the anterior walker, increased walking speed (16.7%-21.4%) with the posterior walker. Elbow extensor and wrist flexor demands were greater with the anterior walker (-0.19 Nm/kg, 0.07 Nm/kg) than with the posterior walker (-0.06 Nm/kg, 0.02 Nm/kg). The methodology developed in this study appears to provide improved insight into the effect of upper extremity muscular demands in addition to the traditional lower extremity gait analysis, clinical evaluation, and energy expenditure assessment.","PeriodicalId":343260,"journal":{"name":"Pediatric Gait: A New Millennium in Clinical Care and Motion Analysis Technology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121595136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two theories are prominent in explaining the presence of anterior ground reaction forces (GRFs) needed to accelerate the body center-of-mass (COM) in the direction of progression. The first involves the posture of the body, i.e., the position of the COM forward of its base of support. The authors test this \"falling COM model\" by computer simulations of an inverted pendulum and find partial explanation for anterior GRFs. The second theory involves the use of mechanical power at the lower extremity joints to perform work on the body and cause changes in its mechanical energy. The authors demonstrate that these two theories complement each other, and both can be used to interpret movement strategies in pathological gait.","PeriodicalId":343260,"journal":{"name":"Pediatric Gait: A New Millennium in Clinical Care and Motion Analysis Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114257497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
