No association between q-angle and foot posture with running-related injuries: a 10 week prospective follow-up study.

BACKGROUND/PURPOSE:
There is a paucity of knowledge on the association between different foot posture quantified by Foot Posture Index (FPI) and Quadriceps angle (Q-angle) with development of running-related injuries. Earlier studies investigating these associations did not include an objective measure of the amount of running performed. Therefore, the purpose of this study was to investigate if kilometers to running-related injury (RRI) differ among novice runners with different foot postures and Q-angles when running in a neutral running shoe.
METHODS:
A 10 week study was conducted including healthy, novice runners. At baseline foot posture was evaluated using the foot posture index (FPI) and the Q-angle was measured. Based on the FPI and Q-angle, right and left feet / knees of the runners were categorized into exposure groups. All participants received a Global Positioning System watch to allow them to quantify running volume and were instructed to run a minimum of two times per week in a conventional, neutral running shoe. The outcome was RRI.
RESULTS:
Fifty nine novice runners of mixed gender were included. Of these, 13 sustained a running-related injury. No significant difference in cumulative relative risk between persons with pronated feet and neutral feet was found after 125 km of running (Cumulative relative risk = 1.65 [0.65; 4.17], p = 0.29). Similarly, no difference was found between low and neutral Q-angle (Cumulative relative risk = 1.25 [0.49; 3.23], p = 0.63).
CONCLUSION:
Static foot posture as quantified by FPI and knee alignment as quantified by Q-angle do not seem to affect the risk of injury among novice runners taking up a running regimen wearing a conventional neutral running shoe. These results should be interpreted with caution due to a small sample size.

hm, as if running on a conventional, neutral runningshoe means, that the conditions for everybody are the same. When will people start to understand, that a "neutral" shoe DOES NOT ACT NEUTRAL. There are lots of people who run much worse (in many aspects) on a so-called neutral running shoe, than they do barefoot. I understand, that it is difficult to rule out the effect of the running shoe, but I know also, that putting everyone on the same shoe is not going to work.

EFFECTS OF Q-ANGLE ON LOWER EXTREMITY BIOMECHANICS AND
INJURIES IN FEMALE COLLEGIATE TRACK AND FIELD ATHLETES
MYRANDA HOPE HAM
Candidate for Master of Science in Engineering, Biomedical Engineering,
Mercer University, May 2020

The purpose of this study is to investigate the effect that quadriceps angle, or Qangle, has on lower extremity biomechanics in female collegiate track and field athletes,
and in turn, investigate the effect that Q-angle has on the incidence of sports-related
injury. Twenty members of the Mercer University Women’s Track and Field team were
asked to participate in this study. Each subject’s limb length and Q-angle were measured
and 2D gait analysis was performed in the Mercer Biomechanics and Gait Lab. Then,
electromyographic (EMG) analysis was performed on eleven of the subjects on one of the
university’s intramural fields. Each subject was also asked to provide a full history of
sports injuries they had previously sustained. For data analysis, the subjects were divided
into three groups based on Q-angle (group 1: 10⁰-14⁰, group 2: 15⁰-17⁰, and group 3:
18⁰+). Statistical analysis was performed using t-tests and Mood’s median tests to
compare the three groups.
Subjects from group 1 were found to have a lower angle of hip adduction (p=0.002
compared to group 2 and p=0.05 compared to group 3) in the left frontal plane at initial
contact and high incidence of shin splints (66.67%) and ankle sprains (33.33%). Subjects
from group 2 were found to have larger range of motion of the knee in the sagittal plane
on the right side (p=0.021 compared to group 1) and higher incidence of hamstring
strains (50%) than the other groups. Subjects from group 3 were found to have high
incidence of shin splints (50%) and injuries to the knee (26.67%). Although no statistical
significance was found in the EMG data, meaningful trends were observed. Muscle
activity in the vastus lateralis, rectus femoris, and lateral gastrocnemius was found to
increase as Q-angle decreased (from group 3 to group 1). In the future, this study could
be done with a higher sample size so more firm conclusions could be drawn.
