Innominate movements during hip abduction and external rotation have recently been described in healthy individuals. In the present study the aim was to determine whether these hip movement tests could discriminate altered movement patterns in people with specific pelvic girdle pain (PGP) disorder. This pilot study is the first step in determining the usefulness of prone hip abduction and external rotation in the differential diagnosis of PGP disorders. A cross-sectional comparison between a convenient sample of 6 individuals who had been referred for exercise and advice following diagnosis of ankylosing spondylitis (AS) via a Medical/Rheumatological pathway and 18 healthy age and gender matched controls. Transverse and sagittal plane innominate motion was measured using a palpation and digitizing technique with a magnetic tracking device. Data analysis involved applying best-fit equations to the data and visual inspection of the produced graphs as well as conditional logistical regression for each test position to determine our ability to predict group association. Graphical comparisons demonstrate a distinction between the patients with AS and the healthy controls. Further, for all three hip conditions the innominate angle was a significant predictor of group association (p = 0.002 for AB, p = 0.005 for AB + ER and p = 0.007 for ER).
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 September 2012.
All research outputs
#19,158,222
of 27,784,943 outputs
Outputs from Manual Therapy
#759
of 1,019 outputs
Outputs of similar age
#132,590
of 193,586 outputs
Outputs of similar age from Manual Therapy
#23
of 28 outputs
Altmetric has tracked 27,784,943 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,019 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.7. This one is in the 16th percentile – i.e., 16% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 193,586 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 28 others from the same source and published within six weeks on either side of this one. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
