Substantiating Appropriate Motion Capture Techniques for the Assessment of Nordic Walking Gait and Posture in Older Adults

Cited by 5 •
2016
The aim was to substantiate optimal use of data collection techniques for Nordic walking gait and posture analysis. Three-dimensional motion capture should be used during short duration analysis (i.e. single gait cycle), while accelerometry should be employed for longer duration analysis (i.e. repeated cycles) like a 6 Minute Walk Test.

Nuclear Stability

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters. To hold positively charged protons together in the...

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

FAQs
Stable walking depends on more than leg strength alone. Vision, vestibular input, and proprioception provide information about body position and movement, while neuromuscular adjustments use that information to regulate balance during ongoing steps. Examining how these systems work together helps clinicians consider whether an observed mobility problem may reflect altered sensory coordination, motor control, or both.
The body’s center of mass must remain in a controllable relationship to the base of support as a person walks. This relationship becomes especially important when the walking direction changes or an external perturbation challenges balance. Evaluating these situations can reveal control problems that may be less apparent during uncomplicated, straight-ahead walking.
Turns and external perturbations challenge the adjustments that maintain balance during movement. A person may appear steady under routine walking conditions yet show difficulty when the direction changes or balance is disturbed. Including these challenges in assessment gives clinicians additional information about adaptability, coordinated control, and potential fall-related mobility concerns.
Assessment can combine observational examination, instrumented walking analysis, and responses to balance challenges. Observation provides a clinical view of walking behavior, whereas instrumented analysis supplies measured information during walking. Balance challenges examine how the person responds when stability is tested. Using these approaches together supports a broader evaluation than any single method alone.
Observational examination allows clinicians to evaluate gait directly during a clinical encounter, while instrumented walking analysis adds objective measurements of walking performance. These approaches address related but different aspects of assessment. Their combined use can help document mobility changes, support treatment monitoring, and provide information for rehabilitation planning when clinical observation alone may not capture every change.
Gait stability assessment can support diagnosis, rehabilitation planning, and treatment monitoring. It is also useful for evaluating mobility changes associated with neurological, musculoskeletal, and aging-related conditions. Because assessment may include routine walking and balance challenges, clinicians and researchers can use the findings to examine both everyday mobility and the ability to respond when walking conditions become more demanding.
