“…As expected, the FS STW duration was shorter and within the documented range of decrease (from −24 % up to −28 %) [12][13][14]. Overall, the significant alterations due to FS, highlight the critical role of the preparatory Leaning phase -during which the feet unloading and loading take place -for the STW motor control.…”

“…The participants sat at a backless and armless platform allowing the seat height standardization to 100 % of lower leg length (from the ground to knee joint center), the hip and knee joint angles at 90 °, the two-thirds of the thighs length in contact with the seat, the feet flat on the floor, and their arms folded in front of them dur-ing the entire task [2,[12][13][14]19]. They were instructed to look straight ahead, to distribute their body weight evenly on both feet and, upon the vocal command "GO", to stand up and walk towards a target placed 2m in front of the seat (not required to cover the full distance).…”

“…To the best of our knowledge, there appear three studies specifically aiming to examine the motion speed effect on the STW movement [12][13][14]. These studies report about various spatial and temporal, kinetic or kinematic, STW characteristics; however, except for the data provided by Kondilopoulos et al [14], little is known about the motion speed effect on the STW spatial and relative temporal pattern. The relative STW temporal pattern may allow a more comprehensive insight regarding the way forces and velocities are generated under a temporal constraint such as the fast motion speed.…”

Sit-to-Walk (STW) is a critical task for daily independence, yet its two inherent destabilizing events (seat-off, walking initiation) may diminish postural stability under fast motion speed (FS). This study aimed at the FS effect on the STW spatial and temporal patterns, with a specific interest in the relative STW temporal pattern. The STW kinetics and kinematics were recorded (n=18 men, 20.7±2.0 years) at preferred and FS. Statistics included One-Way repeated measures ANOVA (SPSS 25.0, p≤0.05). The FS spatial pattern reveals a discontinuous mode of the forward ground reaction force, indicating a balance rather than a propulsive strategy during the Rising phase. The FS relative temporal pattern reveals the prolongation of the Leaning phase (most possibly due to the feet repositioning), the shortening of the Rising and the Walking phases, and a relative delay in the spatial variables (p≤0.05). Overall, the results do not allow the STW consideration at FS as a “magnified” with respect to force, or a “shrinked-in” with respect to time, copy of the preferred motion speed. As more generic and versatile than the absolute one, the relative temporal pattern may be used as a reference for a variety of populations.

“…Another study found that increases in angular velocity and linear accelerations during STW may predispose healthy, young individuals for balance loss. 15) Additionally, another study compared the characteristics of STW in healthy young and healthy elderly individuals. 16) They found differences in the center of pressure paths between the two groups of participants and concluded that the more varied center of pressure paths seen in the elderly participants were indicative of decreased postural stability.…”

Assessing functional mobility is an important aspect of determining fall risk in the growing population of assisted living. Little is known about the sit to walk (STW) transition, especially what characteristics correlate with the duration it takes to perform a STW. Methods In this cross sectional, exploratory study, 45 assisted living residents were evaluated for baseline measures: history of falls, assistive device (AD), lower extremity strength, and balance (Tinetti POMA). The residents were then timed performing a STW, and, from these durations, were stratified into fast and slow groups. Statistical analysis was performed to determine relationships between the two duration groups and the baseline measures. Results Participants who had experienced a fall were significantly more likely to use an assistive device (p = 0.001). The use of an AD had a moderate negative correlation with composite strength (r =-0.428, p = 0.003). Duration of STW had a weak negative correlation with composite strength (r =-0.299, p = 0.046) and a moderate correlation with use of AD (r = 0.419, p = 0.004). Those with a faster duration of STW had significantly better balance (p = 0.027). Conclusion These correlations support the need for healthcare professionals to address the use of adaptive equipment and physical training when evaluating functional mobility in assisted living residents. Providing appropriate equipment and improving overall strength in these individuals can help reduce their risk of falls. Individuals in assisted living facilities can be assessed similar to other geriatric populations, with special consideration on functional tasks and measures.
