Comparison of sit-to-stand strategies used by older adults and people living with dementia

Identification of Movement Strategies During the Sit-to-Walk Movement in Patients With Knee Osteoarthritis

“…A novel numerical procedure was used to identify movement patterns and dissimilarities in the behaviour of control participants and patients with osteoarthritis of the knee. The results obtained in this study are in agreement with the findings in the observation study of older adults and people living with dementia performing the sit-to-stand movement by Dolecka et al 22 Leaning forward was the most common movement strategy, used in 88.5% of the trials by the control group in this study compared to 100% previously reported. 22 The foot backward strategy was observed in 34.6% of the control trials in this study compared to 33.3%…”

“…reported by Dolecka et al 22 Other similar strategies are observed in this, and the abovementioned study 22 with similar frequencies: pushing through knees in 46.2% and 36.6%…”

“…The scoot forward may also make the task easier, 22,25,45,46 however, this type of movement was not adopted by healthy older adults. 22 Our analysis cannot identify this strategy since the progression of the pelvis was not considered when constructing the matrices. Nevertheless, this strategy is infrequent and can be excluded Considering different body segments independently, which in reality act in concert, has its own merit.…”

“…Apart from a single participant whose chair was re-adjusted, all other subjects performed the task with the chair at 100% of knee height. Similarly to Dolecka et al and Farquhar et al, 22,42 a table with a target object was placed three meters in front of the chair. The participants were instructed, on the count to three, to stand up, approach the table and pick up the target object.…”

“…[18][19][20][21] The identification of movement strategies, or the study of their effects has been achieved via questionnaires, video observation and motion analysis. [22][23][24][25][26] Pushing through the armrest, pushing through the knees, scooting forward, leaning forward, thorax flexion and obliquity, feet backward, and no arms used have all been identified as categories of movement strategy. 22,23,25 However, to the authors' knowledge, there are no studies describing numerical tools to identify and classify the standing movement, potentially facilitating rapid analysis of motion capture data with minimal visual inspection.…”
