“…Despite the disparity in the evidence base, clinicians assess knee kinematics in the frontal plane, and specifically for knee valgus, as a means of explaining patient symptoms (Barker-Davies et al, 2018;Neal, 2017). However, when assessing runners with PFPS for whom running is the main aggravating factor, running gait analysis is often foregone for reasons that include a lack of skill, time and resources.…”

Background: Knee kinematics when running, specifically knee valgus, have been linked to patellofemoral pain syndrome. Assessing running biomechanics requires skill, equipment and time. Clinically, the single leg squat is used to make inferences about knee kinematics during running. No evidence supports this practice. Methods: Sixteen asymptomatic runners and sixteen runners with patellofemoral pain syndrome were recruited. Asymptomatic runners were subdivided by dominant and non-dominant leg and runners with patellofemoral pain syndrome by painful and non-painful leg. This gave four groups. Participants were videoed performing single leg squats and running on a treadmill. Frontal plane knee kinematics were calculated using the frontal plane projection angle. Correlation in frontal plane projection angle between running and single leg squat were calculated using Pearson's correlation coefficient. Differences in frontal plane projection angle between groups for running and single leg squat were calculated using multiple independent t-tests with Bonferroni correction. Findings: Correlation in frontal plane projection angle between running and the single leg squat was not statistically significant for the painful leg group (p = 0.19) but was for the remaining groups (p < 0.05). There was no statistically significant difference in frontal plane projection angle between the four groups when running. Single leg squat frontal plane projection angle was significantly larger for the painful leg group (10.3°) than the dominant leg (−0.2°(p = 0.003)) and non-dominant leg (−0.4°(p = 0.004)) in the asymptomatic runners group. Interpretation: The single leg squat cannot be used to make inferences about frontal plane knee kinematics in running gait in patellofemoral pain syndrome sufferers.

“…For example, increased hip and trunk flexion during the small knee bend (SKB) test which assesses hip movement control were observed in male academy footballers with 5 MRI confirmed morphological changes associated with FAI 11 . The SKB test is commonly used in the literature [12][13][14][15] , and participants with poor SKB test scores exhibited weaker and slower muscle activation of the hip abductors, indicative of hip muscle dysfunction 16 . Trunk rotation is required in sports that involve actions such as kicking, sprinting and changes of direction, which are common in football.…”

Accuracy of movement quality screening to document effects of neuromuscular control retraining exercises in a young ex-footballer with hip and groin symptoms: A proof of concept case study

Hip and groin pain is common in footballers and altering movement patterns can reduce symptoms. Observational tests of movement control are thought to identify abnormal movement patterns, but their accuracy needs yet to be confirmed by comparison with an objective measure. To assess the accuracy, using 3D motion analysis, of observational movement control tests and their ability to detect changes, and document changes in symptoms following a neuromuscular control exercise programme in an ex-footballer with hip and groin pain. A 25-year-old male with chronic bilateral hip and groin pain had their movement control ability rated and kinematic data collected using 3D motion analysis while performing Small Knee Bend (SKB) and SKB with Rotation (SKB Rot) tests pre-and post-neuromuscular control exercise training. Movement control was rated as at fault if they were unable to control specific trunk and pelvic movements during the tests. The Copenhagen Hip and Groin Outcome Score (HAGOS) was used to assess symptoms. Following the intervention, observational rating during the SKB test improved from fault to no fault for anterior pelvic tilt, which decreased by 17° and 16° during right and left leg SKB tests respectively. The HAGOS symptoms subsection improved from 36% to 61%. Observational movement screening ratings were supported by 3-D motion analysis. These findings indicate that the screening tool was accurate for detecting improvements in trunk and pelvic movement control following an exercise programme in an ex-footballer who had presented with hip and groin pain.

“…For kinematic and kinetic data acquisition and processing 8 body segments (feet, shank, thigh, pelvis and trunk) were defined using retro-reflective markers placed on anatomical landmarks by the same operator (RBD) as previously described by this laboratory 25 (article submitted, Barker-Davies 2017). Joint moments were normalised to participant mass.…”
