“…The body of literature suggested that hip flexion angle contributed to rising from a seated position in healthy subjects ( 28 ). The results of this study showed that people with subacute stroke decreased maximal hip flexion angle during T 1 when compared with healthy adults before standing up from a seated position.…”

ObjectiveThe aim of this study was to detect the key changes during sit-to-stand (STS) movement cycle in hemiparetic stroke survivors using a five-phase kinematic and kinetic analysis.MethodsTwenty-five subacute stroke survivors and 17 age-matched healthy adults participated in this study. The kinematic and kinetic parameters during STS cycle were measured using three-dimensional motion analysis system with force plates. The five standard phases of STS cycle were identified by six timing transitional points.ResultsLonger total time as well as larger changes were observed at the initial phase (phase I, 0.76 ± 0.62 VS 0.43 ± 0.09 s; p = 0.049) and at the end of hip and knee extension phase (phase IV, 0.93 ± 0.41 VS 0.63 ± 0.14 s; p = 0.008) in the stroke group than healthy group. Time to maximal knee joint moment was significantly delayed in the stroke group than in the control group (1.14 ± 1.06 VS 0.60 ± 0.09 s, p < 0.001). The maximal hip flexion was lower during the rising phase from seated position on the affected side in the stroke group than in the control group (84.22° ± 11.64°VS 94.11° ± 9.40°; p = 0.022). Ground reaction force was lower (4.61 ± 0.73 VS 5.85 ± 0.53 N, p < 0.001) in the affected side of the stroke group than in the control group. In addition, knee joint flexion was significantly lower at just-standing phase (T4) and at end point (T5) (5.12° ± 5.25° VS 8.21° ± 7.28°, p = 0.039; 0.03° ± 5.41° VS 3.07° ± 6.71°, p = 0.042) on the affected side than the unaffected side. Crucial decrease of knee joint moment at abrupt transitory (T2) and the maximal moment was also observed on the affected side in comparison with the unaffected side (0.39 ± 0.29 VS 0.77 ± 0.25 Nm/kg, p < 0.001; 0.42 ± 0.38 VS 0.82 ± 0.24 Nm/kg, p < 0.001).ConclusionThe findings of movement decomposition analysis provided useful information to clinical evaluation of STS performance, and may potentially contribute to the design of rehabilitation intervention program for optimum functional recovery of STS after stroke.

“…Although several studies have examined lumbar kinematics during a single functional activity test,(Alqhtani et al, 2015; Shum et al, 2005a, b, 2007) very little has been reported on the consistency of aspects of the lumbar movement pattern across multiple functional activity tests. Marras et al reported people with LBP displayed increased cumulative spinal loading compared to BH people during a lifting task from varying heights and distances.…”

Background Limitation in function is a primary reason people with low back pain seek medical treatment. Specific lumbar movement patterns, repeated throughout the day, have been proposed to contribute to the development and course of low back pain. Varying the demands of a functional activity test may provide some insight into whether people display consistent lumbar movement patterns during functional activities. Our purpose was to examine the consistency of the lumbar movement pattern during variations of a functional activity test in people with low back pain and back-healthy people. Methods 16 back-healthy adults and 32 people with low back pain participated. Low back pain participants were classified based on the level of self-reported functional limitations. Participants performed 5 different conditions of a functional activity test. Lumbar excursion in the early phase of movement was examined. The association between functional limitations and early phase lumbar excursion for each test condition was examined. Findings People with low back pain and high levels of functional limitation demonstrated a consistent pattern of greater early phase lumbar excursion across test conditions (p<.05). For each test condition, the amount of early phase lumbar excursion was associated with functional limitation (r=0.28–0.62) Interpretation Our research provides preliminary evidence that people with low back pain adopt consistent movement patterns during the performance of functional activities. Our findings indicate that the lumbar spine consistently moves more readily into its available range in people with low back pain and high levels of functional limitation. How the lumbar spine moves during a functional activity may contribute to functional limitations.

“…Studies where participants performed 2 or more movement tests primarily have focused on differences between (1) BH people and people with LBP, (2) LBP subgroups, or (3) patterns of movement at different movement speeds and object locations rather than the relationship between the movement during the tests . A recent study by Alqhtani et al reported an association between maximal upper ( r = 0.57) and lower ( r = 0.83) lumbar excursion during FWB and during a functional activity test separately . Different from the current study, however, the Alqhtani study included only BH males, there was no examination of lumbar excursion at increments of movement time, and the functional activity test involved picking up an object from the floor.…”

Background It is assumed that the lumbar movement pattern observed during a clinical test is representative of the movement pattern used during a functional activity. Very little is known about how the lumbar movement pattern during a clinical test is associated with the lumbar movement pattern during a functional activity and how the lumbar movement pattern is associated with functional limitation. Objective The purpose was to examine the lumbar movement pattern during a clinical test and a functional activity test in people with and people without low back pain (LBP), and the relationship of lumbar motion to LBP‐related functional limitation. Design Observational study. Participants 16 back‐healthy adults and 32 people with chronic LBP. Methods Participants performed a standardized clinical test of forward bending and a functional activity test of picking up an object. Main Outcome Measurements Maximal lumbar excursion and lumbar excursion at 0% to 50% and 50% to 100% of movement time were examined. Results Significant associations were present between the two movement tests for both back‐healthy people and people with LBP (r = 0.47‐0.73). In people with LBP the amount of lumbar motion in the 0% to 50% of movement time interval for both tests was significantly associated with functional limitation (r = 0.43‐0.62). Conclusion Lumbar movement patterns were similar between the two tests, and lumbar motion early in the movement of a functional test was related to self‐report of functional limitation.

Correlation of Lumbar-Hip Kinematics Between Trunk Flexion and Other Functional Tasks

Abstract: Strong correlations were only evident for the LL spine ROM between lifting and flexion; all other tasks afforded moderate or weak correlations. This study suggests that sagittal tasks use different lumbar-hip kinematics and place different demands on the lumbar spine and hip.
