The effects of sex and competitive status (athlete vs nonathlete) on ankle inversion-eversion range of motion was investigated. 62 collegiate athletes and 36 collegiate nonathletes, both male and female, were tested. Analysis of variance showed significant (p<.05) main effects for sex but not competitive status or sex x competitive status. These results imply that college age women have more ankle rotational range of motion than men and that collegiate athletes in a group of various sports do not differ in ankle range of motion when compared to college nonathletes. Power in this sample did not permit definitive assessment.
walking with and without orthosis. The gait speed also showed no change. Rest pain showed a tendency towards reduction, but the initial value and the value 4 weeks after treatment did not differ. Stress pain reduced significantly after 4 weeks. The Likert scale showed an improvement in almost all patients but in one patient after a 4-week a worsening. A later arthroscopy showed a pronounced chondrocalcinosis in this certain patient, which explains the deterioration in this case. In the questionnaire KOOS all items showed significant differences. All items improved significantly. Conclusions: In summary, it can be stated that the orthosis significantly improved the subjective well-being of the patients after 4 weeks. Especially the reduction of stress pain shows the positive effect of the orthosis in patients with medial knee arthrosis. Improvement in many questionnaires items (pain, function, activities of daily living) were seen after 4 weeks of using the orthosis.
Robotic assisted rehabilitation, taking advantage of neuroplasticity, has been shown to be helpful in regaining some degree of gait performance. Robot-applied movement along with voluntary efferent motor commands coordinated with the robot allows optimization of motion training. We present the design and characteristics of a novel foot-based 6-degree-of-freedom (DOF) robot-assisted gait training system where the limb trajectory mirrored the normal walking gait. The goal of this study was to compare robot-assisted gait to normal walking gait, where the limb moved independently without robotics. Motion analysis was used to record the three-dimensional kinematics of the right lower extremity. Walking motion data were determined and transferred to the robotic motion application software for inclusion in the robotic trials where the robot computer software was programmed to produce a gait pattern in the foot equivalent to the gait pattern recorded from the normal walking gait trial. Results demonstrated that ankle; knee and hip joint motions produced by the robot are consistent with the joint motions in walking gait. We believe that this control algorithm provides a rationale for use in future rehabilitation, targeting robot-assisted training in people with neuromuscular disabilities such as stroke.
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.
