“…A unilateral squat test requires a piece of specific equipment such as adjusted‐weight barbells to determine the amount of leg strength 9 . The strength evaluation of LE muscles using a two‐leg STS may not be a true reflection of strength from each leg equally, as asymmetrical LE joint moments between right and left legs was reported during a two‐leg STS task 12,13 . Also, young healthy adults have relatively higher maximal voluntary contraction than older adults and utilise less of their strength capability during a traditional two‐leg STS performance 13 .…”

Background One‐leg sit‐to‐stand (one‐leg STS) test is a new clinical test developed to measure the unilateral lower limb (LE) muscle strength among young adults. This study examined the test‐retest reliability and the criterion‐concurrent validity of the one‐leg STS. Methods Forty young adults (mean age ± SD, 28.07 ± 5.39 years) participated in the study. The one‐leg STS test was administered in two separate assessment sessions to examine test‐retest reliability. Two‐leg STS test was administered and the performance time was measured. The concentric peak strength of hip flexors/extensors, knee flexors/extensors and ankle dorsi‐flexors/plantar‐flexors were determined using an isokinetic dynamometer. An intraclass correlation coefficient (ICC) was used to examine the test‐retest reliability of one‐leg STS test. The criterion validity of the one‐leg STS test was evaluated against the performance of the two‐leg STS test using an independent sample t test. The concurrent validity of the one‐leg STS test was evaluated by investigating the relationships between STS performance time and LE muscle strength using Pearson correlation coefficients. Results The reliability analysis showed that one‐leg STS performance time had excellent test‐retest reliability (ICC3,1 = 0.960, P < .001). Also, the one‐leg STS performance time was not different between the first and second sessions, t (39) = 0.672, P = .506. The performance time of the one‐leg STS test was significantly greater than the two‐leg STS test (t (39) = 20.63, P < .001). The performance time of the one‐leg STS test significantly correlated with the concentric peak strength of all LE muscles (P < .05). Conclusions The one‐leg STS test demonstrated excellent reliability and criterion‐concurrent validity against the two‐leg STS and the LE muscle strength. The one‐leg STS test was simple to administer and could be beneficial for the assessment of unilateral LE muscle strength of young adults in clinical settings.

“…Factors affecting STS movement include chair seat height (Arborelius, Wretenberg & Lindberg, 1992;Janssen, Bussmann & Stam, 2002;Kuo, Tully & Galea, 2010;Schenkman, Hughes, Samsa & Studenski, 1996;Yamada & Demura, 2004), use of armrests or arms (Alexander, Schultz & Warwick, 1991;Arborelius et al, 1992;Eriksrud & Bohannon, 2003;Etnyre & Thomas, 2007;Janssen et al, 2002;Leung & Chang, 2009;Schultz, Alexander & Ashton-Miller, 1992), use of handrails (O'Meara & Smith, 2005;O'Meara & Smith, 2006), foot positioning (Janssen et al, 2002;Khemlani, Carr & Crosbie, 1999;Lecours, Nadeau, Gravel & Teixera-Salmela, 2008;Vander Linden, Brunt & McCulloch, 1994), trunk positioning (Schenkman, Berger, Riley, Mann & Hodge, 1990), STS movement speed (Bieryla, Anderson & Madigan, 2009;Hanke, Pai & Rogers, 1995;Pai & Rogers, 1990;Vander Linden et al, 1994), age (Alexander et al, 1991;Lundin, Grabiner & Jahnigen, 1995;Schultz et al, 1992;Zijlstra, Bisseling, Schlumbohm & Baldus, 2010), and hip angles (Gotoh, Takada & Suehiro, 2002). Nevertheless, no report describes kinematic differences in hip abduction and ex-ternal rotation angles on the STS movement.…”

Functional Significance of Sit-to-stand by Hip Abduction with External Rotation Angle

The principal aim of this study was to analyze the effects of differences in hip abduction and external rotation angles on sit-to-stand (STS) movements. Hip abduction and external rotation angles of 0 deg (closed legs parallel to each other) and 45 deg (open legs) of 27 healthy participants were compared. Analysis parameters were the center of pressure, the ground reaction force, and the activities of fourteen muscles using surface electromyography. The center of pressure parameter revealed that standing with open legs requires less anterior-posterior displacement during STS movement. The open leg movement showed that ground reaction force differed slightly for right and left sides. Muscle activity of the erector spinae and tibialis anterior decreased with the STS movement with open legs. In contrast, muscle activity of the adductor longus and the biceps femoris increased.

“…(Gilleard et al, 2008, Lundin et al, 1995, Portegijs et al, 2006, Portegijs et al, 2008) In community dwelling elderly participants, asymmetries in “explosive power” of leg muscles (e.g. measured during a seated task) are higher in fallers as compared to non-fallers (Portegijs et al, 2006, Skelton et al, 2002), and participants with mobility limitation compared to participants without mobility limitation.…”

“…In healthy adults, studies noted mild asymmetry (<10%) of joint movements and loading during a STS task. (Lundin et al, 1995, Gilleard et al, 2008) Therefore, large asymmetries (>20%) of leg extensor power known to occur in participants after a hip fracture are anticipated to result in significant side to side differences in lower extremity movement patterns. These differences in movement patterns are theorized to contribute to balance and functional deficits.…”

Background-A sit to stand task following a hip fracture may be achieved through compensations (e.g. bilateral arms and uninvolved lower extremity), not restoration of movement strategies of the involved lower extremity. The primary purpose was to compare upper and lower extremity movement strategies using the vertical ground reaction force during a sit to stand task in participants recovering from a hip fracture to control participants. The secondary purpose was to evaluate the correlation between vertical ground reaction force variables and validated functional measures.
