“…Therefore, the hip should help move the frontal plane in this coupling. Davis et al [ 44 ] argued that the proximal coordination pattern indicated more proximal joint (the hip) contribution to motion relative to the distal joint (the knee). In other words, if the coupling angle falls within the proximal phase range, the hip has a larger movement than the knee.…”

“…In the coupling of the hip to the knee, the hip acts as a stabilizer in response to increased knee movement or instability. Therefore, the coupling angles increase so that the hip has fewer movements, and an attempt to increase the stability is shown [ 44 ]. The results obtained in this study differed from those of Davis et al [ 44 ] and maybe the reason for this difference is the type of task being evaluated.…”

Background This study sought to determine the effects of a 6-week neuromuscular training (NMT) and NMT plus external focus (NMT plus EF) programs on trunk and lower extremity inter-segmental movement coordination in active individuals at risk of injury. Methods Forty-six active male athletes (controls = 15, NMT = 16, NMT plus EF = 15) participated (age = 23.26 ± 2.31 years) in this controlled, laboratory study. Three-dimensional kinematics were collected during a drop vertical jump (DVJ). A continuous relative phase (CRP) analysis quantified inter-segmental coordination of the: (1) thigh (flexion/extension)—shank (flexion/extension), (2) thigh (abduction/adduction)—shank (flexion/extension), (3) thigh (abduction/adduction)—trunk (flexion/extension), and (4) trunk (flexion/extension)—pelvis (posterior tilt/anterior tilt). Analysis of covariance compared biomechanical data between groups. Results After 6 weeks, inter-segmental coordination patterns were significantly different between the NMT and NMT plus EF groups (p < 0.05). No significant differences were observed in CRP for trunk-pelvis coupling comparing between NMT and NMT plus EF groups (p = 0.134), while significant differences were observed CRP angle of the thigh-shank, thigh-trunk couplings (p < 0.05). Conclusions Trunk and lower extremity movement coordination were more in-phase during DVJ in the NMT plus EF compared to NMT in active individuals at risk of anterior cruciate ligament injury. Trial registration: The protocol was prospectively registered at UMIN_RCT website with ID number: UMIN000035050, Date of provisional registration 2018/11/27.

“…Defined as the variation in motor performance over multiple repetitions of a task (James et al, 2000), movement variability has been explored in clinical presentations including, acute injury and pain (Seay et al, 2011, Weir et al, 2019, overuse injury (Hamill et al, 2012), injury recurrence (Edwards et al, 2017, Davis et al, 2019, pathology (Kawakami et al, 2019) and aging (Hausdorff et al, 2001). Therefore, movement variability is of interest to the clinician.…”

“…Therefore, movement variability is of interest to the clinician. The degree of movement variability may be a marker of a robust movement system, a theme apparent within clinically focussed, coordination variability literature (Davis et al, 2019, Kawakami et al, 2019, Weir et al, 2019. Although these emerging papers are highlighting the importance of considering movement variability, currently there is little direct translation into the clinic in terms of assessment and rehabilitation.…”

“…Studies into stride-to-stride variability indeed found decreased variability in ACL-deficient individuals compared to the intact contralateral knee and to healthy control knees (Decker et al, 2011;Moraiti et al, 2007). However, some studies have found more variability in ACLR-participants compared to healthy controls (Davis et al, 2019;Leporace et al, 2013;Moraiti et al, 2009;Moraiti et al, 2010). Presumably, the individual feels secure to add extra motion after ACLR even though the proprioceptive channels are not yet restored.…”

Background: In the current study changes in lower-limb motor flexibility of patients undergoing Anterior Cruciate Ligament Reconstruction were evaluated in relation to fear of harm. Methods: Fourteen patients were measured pre-and post-surgery, and data were compared to those of a single measurement in fifteen controls. Lower-limb motor-flexibility was assessed in treadmill-walking and a cyclic legamplitude differentiation task augmented with haptic or visual feedback. Flexibility was captured by determining the between-leg coordination-variability (SD of relative phase) and each leg's temporal variability (sample entropy). Patients were post hoc divided into a higher-fear-group (pre-surgery: n = 6, post-surgery: n = 7) and a lower-fear-group (pre-surgery: n = 6, post-surgery: n = 7) by means of a median split of their scores on a self-reported fear of harm scale. Differences in flexibility-measures between the higher-fear-group and the lowerfear-group were also assessed. Findings: No pre-and post-surgery differences, nor differences with the control group, were found in motorflexibility during treadmill-walking but the post-surgery higher-fear-group did show lower values of SD relative phase. In the leg-amplitude differentiation task the SD of the relative phase decreased but sample entropy increased post-surgery towards levels of the control-group. The pre-surgery higher-fear-group showed lower values of sample entropy in visual conditions. Interpretation: While gait kinematics may not show motor-flexibility changes following anterior cruciate ligament reconstruction, a leg-amplitude differentiation task does show such changes. Differentiating patients on a fear-ofharm scale revealed subtle differences in motor-flexibility. Challenging patients with non-preferred movements such as amplitude differentiation may be a promising tool to evaluate motor-flexibility following ACLR.
