Abstract Background Use of a wearable gait analysis system (WGAS) is becoming common when conducting gait analysis studies due to its versatility. At the same time, its versatility raises a concern about its accuracy, because its calculations rely on assumptions embedded in its algorithms. The purpose of the present study was to validate all spatiotemporal gait parameters calculated by the WGAS by comparison with simultaneous measurements taken with an optical motion capture system (OMCS). Methods Ten young healthy volunteers wore two inertial sensors of the commercially available WGAS, Physilog®, on their feet and 23 markers for the OMCS on the lower part of the body. The participants performed at least three sets of 10-m walk tests at their self-paced speed in the laboratory equipped with 12 high-speed digital cameras with embedded force plates. To measure repeatability, all participants returned for a second day of testing within two weeks. Results All gait parameters calculated by the WGAS had a significant correlation with the ones determined by the OMCS. Bland and Altman analysis showed that the between-device agreement for all gait parameters was within clinically acceptable limits. The validity of the gait parameters generated by the WGAS was found to be excellent except for two parameters, swing width and maximal heel clearance. The repeatability of the WGAS was excellent when measured between sessions. Conclusion The present study showed that spatiotemporal gait parameters estimated by the WGAS were reasonably accurate and repeatable in healthy young adults, providing a scientific basis for applying this system to clinical studies.

Background:Static wrist splinting after stroke was not effective in facilitating distal movement. However, the purpose of this study is to evaluate the efficacy of training using kinematic parameters after a SaeboFlex orthosis training on chronic stroke patients.Case Description and Methods:Five stroke patients participated in 4 weeks of training using a SaeboFlex orthosis for 1 hour per day, five times per week. Fugl-Meyer Assessment, Box and Block Test, Action Research Arm Test, and Kinematics using a three-dimensional motion analysis system were used for evaluating of training effects.Findings and Outcomes:The upper extremity score of the Fugl-Meyer Assessment and the Box and Block Test score were increased significantly after the intervention. The jerkiness score of the shoulder and elbow joints at the sagittal plane decreased significantly during the reach-to-grasp task at acromion height, and the jerkiness scores of the wrist joint during the reach-to-grasp task decreased significantly at both elbow and acromion heights.Conclusion:The results of this study indicate that a SaeboFlex training is effective in recovering the movement of the hemiparetic upper extremity of patients after stroke.Clinical relevanceUsing a spring-assisted dynamic hand orthosis is considered to be an effective treatment option for providing repetition, task-oriented training, and real-world activities for the hemiparetic upper extremity, which was impaired hand to perform functional training.

Foot Orthosis

Background:An ankle–foot orthosis using an oil damper is designed to enable natural movement of the ankle joint. Wearing an ankle–foot orthosis using an oil damper has been demonstrated to assist the first rocker in stroke patients, but its effect on their gait when not wearing it is unclear.Objectives:To determine the effect of use of ankle–foot orthosis using an oil damper on the gait of stroke patients with hemiparesis when not wearing the ankle–foot orthosis.Study design:Crossover study.Methods:The gait of eight stroke patients in the chronic phase when not wearing an ankle–foot orthosis was measured, using a three-dimensional motion analysis system, before using the ankle–foot orthosis using an oil damper and then without and with using the ankle–foot orthosis using an oil damper after 3 weeks of use. Differences in gait were compared between the three measurement conditions.Results:Use of ankle–foot orthosis using an oil damper significantly decreased preswing time and significantly increased the positive ankle joint power in stance when not wearing the ankle–foot orthosis using an oil damper.Conclusions:These changes indicate the promising therapeutic effects of ankle–foot orthosis using an oil damper use and suggest the ankle–foot orthosis using an oil damper’s potential as a therapeutic device.Clinical relevanceAfter 3 weeks of use of an ankle–foot orthosis using an oil damper, which assists the first rocker, the gait of stroke patients in the chronic phase when not wearing the ankle–foot orthosis using an oil damper was improved. Preswing time was significantly decreased and positive ankle joint power was significantly increased. The ankle–foot orthosis using an oil damper, which assists the first rocker function with natural movement of the ankle joint during gait, has the potential to improve the gait of stroke patients after immediate-term use.
