TL;DR: The intent of this two part series is to present the concepts associated with screening of fundamental movements, whether it is the FMS™ system or a different system devised by another clinician.
Abstract: Part 1 of this two‐part series (presented in the June issue of IJSPT) provided an introduction to functional movement screening, as well as the history, background, and a summary of the evidence regarding the reliability of the Functional Movement Screen (FMS™). Part 1 presented three of the seven fundamental movement patterns that comprise the FMS™, and the specific ordinal grading system from 0‐3, used in the their scoring. Specifics for scoring each test are presented.
Part 2 of this series provides a review of the concepts associated with the analysis of fundamental movement as a screening system for functional movement competency. In addition, the four remaining movements of the FMS™, which complement those described in Part 1, will be presented (to complete the total of seven fundamental movements): Shoulder Mobility, the Active Straight Leg Raise, the Trunk Stability Push‐up, and Rotary Stability. The final four patterns are described in detail, and the specifics for scoring each test are presented, as well as the proposed clinical implications for receiving a grade less than a perfect “3”.
The intent of this two part series is to present the concepts associated with screening of fundamental movements, whether it is the FMS™ system or a different system devised by another clinician. Such a fundamental screen of the movement system should be incorporated into pre‐participation screening and return to sport testing in order to determine whether an athlete has the essential movements needed to participate in sports activities at a level of minimum competency.
Part 2 concludes with a discussion of the evidence related to functional movement screening, myths related to the FMS™, the future of functional movement screening, and the concept of movement as a system.

TL;DR: It is found that healthy control subjects consistently overestimated the force required when pressing directly on their own finger than when operating a robot, however, patients did not, indicating a significant loss of sensory attenuation in this group of patients.
Abstract: Functional movement disorders require attention to manifest yet patients report the abnormal movement to be out of their control. In this study we explore the phenomenon of sensory attenuation, a measure of the sense of agency for movement, in this group of patients by using a force matching task. Fourteen patients and 14 healthy control subjects were presented with forces varying from 1 to 3 N on the index finger of their left hand. Participants were required to match these forces; either by pressing directly on their own finger or by operating a robot that pressed on their finger. As expected, we found that healthy control subjects consistently overestimated the force required when pressing directly on their own finger than when operating a robot. However, patients did not, indicating a significant loss of sensory attenuation in this group of patients. These data are important because they demonstrate that a fundamental component of normal voluntary movement is impaired in patients with functional movement disorders. The loss of sensory attenuation has been correlated with the loss of sense of agency, and may help to explain why patients report that they do not experience the abnormal movement as voluntary.

TL;DR: The aim of this study was to quantitatively characterize functional changes in upper limb movements in ataxic patients, using an optoelectronic system for objective measurements.
Abstract: Background and purpose: The design of useful and effective treatment strategies for movement disorders largely depends on the ability to objectively quantify changes in performances, providing reliable outcome measures. Evaluation of ataxia remains mainly assigned to different clinical scales, providing a semi-quantitative assessment. The aim of this study was to quantitatively characterize functional changes in upper limb movements in ataxic patients, using an optoelectronic system for objective measurements.
Methods: Fourteen patients with cerebellar ataxia and 27 healthy subjects were analyzed using an optoelectronic system with passive markers during pointing task and hand-to-mouth movement. Quantitative parameters capable of characterizing ataxic movements were defined using recorded kinematics.
Results: In both the considered functional movements, ataxic patients showed increased adjustment during the last phase of movement. The movement was less smooth than that in controls, with a fragmented trajectory presenting more direction changes than controls.
Conclusions: The proposed protocol allows the quantitative characterization of the motion pattern of ataxic subjects in a non-invasive way. We believe that this analysis could represent a good tool for ataxia evaluation in a clinical context such as neurorehabilitation.
TL;DR: An 8-week core stability training program enhances functional movement patterns and dynamic postural control in college athletes, and the benefits are more pronounced inCollege athletes with poor movement quality.
Abstract: Context: Preparticipation examinations are the standard approach for assessing poor movement quality that would increase musculoskeletal injury risk However, little is known about how core stabili
TL;DR: Although sagittal joint positions seemed to increase the external torque on the knee and hip extensors, frontal joint positions appeared to reduce the muscular demands on evertor and hip abductor muscles.
Abstract: IntroductionComprehensive evaluation of movement strategies during functional movement is a difficult undertaking. Because of this challenge, studied movements have been oversimplified. Furthermore, evaluating movement strategies at only a discrete time point(s) provide limited insight into
