“…(Lamb and Stöckl, 2014). Most studies focus on one activity with different speed or under different condition (Wang Y. et al, 2021). To the best of our knowledge this is the first study to examine shank-thigh coordination variability in unilateral tasks with knee extension-flexion of increasing complexity.…”

Interlimb coordination variability analysis can shed light into the dynamics of higher order coordination and motor control. However, it is not clear how the interlimb coordination of people with no known injuries change in similar activities with increasing difficulty. This study aimed to ascertain if the interlimb coordination variability range and patterns of healthy participants change in different unilateral functional tasks with increasing complexity and whether leg dominance affects the interlimb coordination variability. In this cross-sectional study fourteen younger participants with no known injuries completed three repeated unilateral sit-to-stands (UniSTS), step-ups (SUs), and continuous-hops (Hops). Using four inertial sensors mounted on the lower legs and thighs, angular rotation of thighs and shanks were recorded. Using Hilbert transform, the phase angle of each segment and then the continuous relative phase (CRP) of the two segments were measured. The CRP is indicative of the interlimb coordination. Finally, the linear and the nonlinear shank-thigh coordination variability of each participant in each task was calculated. The results show that the linear shank-thigh coordination variability was significantly smaller in the SUs compared to both UniSTS and Hops in both legs. There were no significant differences found between the latter two tests in their linear coordination variability. However, Hops were found to have significantly larger nonlinear shank-thigh coordination variability compared to the SUs and the UniSTS. This can be due to larger vertical and horizontal forces required for the task and can reveal inadequate motor control during the movement. The combination of nonlinear and linear interlimb coordination variability can provide more insight into human movement as they measure different aspects of coordination variability. It was also seen that leg dominance does not affect the lower limb coordination variability in participants with no known injuries. The results should be tested in participants recovering from lower limb injuries.

“…CRP can be used to measure the interactions between segments or joints throughout the gait cycle, enabling the assessment of the overall coordination profile during walking. CRP has been demonstrated to be capable of identifying the essential timing and sequencing of neuromuscular control over biomechanical degree of freedom for a smooth and efficient movement and is considered to be able to complement traditional gait analysis to provide insights into the complexity of human motor behavior ( Chiu et al, 2010 ; Chiu and Chou, 2012 ; Chiu et al, 2013 ; Ogaya et al, 2016 ; Wang et al, 2021 ). SPM is a useful analysis method for clinicians because it is more intuitive than considering discrete variables alone and allows one to explore gait waveform data without a priori assumptions about when in the gait cycle statistical differences might occur, and can further provide objective evidence for best practice clinical decisions making ( Pincheira et al, 2019 ).…”

“…OrthoTrak software (Motion Analysis Inc., Santa Rosa, CA, United States) was used to calculate gait spatiotemporal and kinematic parameters ( Pincheira et al, 2019 ). Thigh, shank, and foot angles in the sagittal plane were calculated with respect to the vertical axis in each frame ( Wang et al, 2021 ). Each gait cycle was time normalized to 100 data points.…”

“…The sample size was calculated with data from our previous study ( Wang et al, 2021 ) with intersegmental coordination in patients with knee OA during walking. The mean shank-foot average CRP during the early stance with the highest standard deviation and the smallest difference between groups was used ( Cabral et al, 2018 ).…”

Precise identification of deficient intersegmental coordination patterns and functional limitations is conducive to the evaluation of surgical outcomes after total knee arthroplasty (TKA) and the design of optimal personalized rehabilitation protocols. However, it is still not clear how and when intersegmental coordination patterns change during walking, and what functional limitations are in patients with TKA. This study was designed to investigate lower limb intersegmental coordination patterns in patients with knee osteoarthritis before and after TKA and identify how intersegmental coordination of patients is altered during walking before and after TKA. It was hypothesized that 6-month after TKA, intersegmental coordination patterns of patients are improved compared with that before TKA, but still do not recover to the level of healthy subjects. Gait analysis was performed on 36 patients before and 6-month after TKA and on 34 healthy subjects. Continuous relative phase (CRP) derived from the angle-velocity phase portrait was used to measure the coordination between interacting segments throughout the gait cycle. Thigh-shank CRP and shank-foot CRP were calculated for each subject. Statistical parametric mapping (SPM), a one-dimensional analysis of the entire gait cycle curve, was performed directly to determine which periods of the gait cycle were different in patients and healthy subjects. Six-month after TKA, thigh-shank CRP was significantly higher during 5–12% of the gait cycle (p = 0.041) and lower during 44–95% of the gait cycle (p < 0.001) compared with healthy subjects, and was significantly higher during 62–91% of the gait cycle (p = 0.002) compared with pre-operation. Shank-foot CRP was significantly lower during 0–28% of the gait cycle (p < 0.001) and higher during 58–94% of the gait cycle (p < 0.001) compared with healthy subjects, and was significantly lower during 3–18% of the gait cycle (p = 0.005) compared with pre-operation. This study found that patients exhibited altered intersegmental coordination during the loading response and swing phase both before and after TKA. Six-month after TKA, the thigh-shank coordination was partially improved compared with pre-operation, but still did not recover to the level of healthy subjects, while there was no improvement in the shank-foot coordination pattern after TKA compared with pre-operation. CRP combined with SPM methods can provide insights into the evaluation of surgical outcomes and the design of rehabilitation strategy.
