Study Design Controlled laboratory setting. Background Individuals following anterior cruciate ligament reconstruction (ACLR) present with significant knee power absorption deficits during deceleration of dynamic tasks. An inability to quantify these deficits clinically may underlie their persistence. Recent studies suggest that segment angular velocities measured with wearable inertial sensors have the potential to provide valuable information about knee power during a single limb loading task. However, diagnostic accuracy of these measures and procedures need to be established before translating this information to clinical practice...

Synopsis Motor control exercise has been shown to be effective in the management of low-back pain (LBP), but effect sizes are modest, possibly due to the fact that studies have used a one-size-fits-all approach, whereas literature suggests that patients may differ in presence or type of motor control issues. In this commentary, we address the question whether consideration of such variation in motor control issues might contribute to more personalized motor control exercise for patients with LBP. Such an approach is plausible, since motor control changes may play a role in persistence of pain through effects on tissue loading that may cause nociceptive afference in particular in case of peripheral sensitization...

Study Design Controlled laboratory study, longitudinal. Background Decreased extensor moments in the surgical knee during bilateral squats can persist longer than one year following anterior cruciate ligament reconstruction (ACLr). This is accomplished using inter-limb and intra-limb compensations. Objectives Assess loading during squatting longitudinally, 3 and 5 months post-ACLr, and to determine the extent to which inter- and intra-limb compensations contribute to reduced knee extensor moments. Methods 11 individuals (4 males) underwent 3-dimensional motion analysis of a squat at 3 and 5 months post-ACLr...

Synopsis Patients with low-back pain have been shown to display differences compared to healthy individuals in all aspects of trunk motor control, most often studied as differences in muscle activity and kinematics. However, differences in these aspects of motor control are largely inconsistent. We propose that this may reflect existence of two phenotypes, possibly the two ends of a distribution, one with "tight" control over trunk movement and one with "loose" control. Both may have beneficial effects, with tight control protecting against large tissue strains from uncontrolled movement and loose control protecting against high muscle forces and resulting spinal compression...
