Thesis (MScPhysio)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Introduction-Groin injuries are among the top six most cited injuries in soccer and account for 10-18 per
cent of all injuries reported in contact sport. Groin pain can result from a variety of
pathologies, but according to literature, 63 per cent of groin pain is due to adductor
pathology.
Objective-The objective of this study was to explore if there are kinematic differences in the hip joint
in sports participants with groin pain compared to matched healthy controls.
Study design
A cross sectional, descriptive study was conducted.
Study setting-The study was conducted at the FNB -3D motion analysis laboratory at the University of
Stellenbosch, South Africa.
Outcome variables-The dependent variables included hip kinematics in the sagittal, frontal and transverse
planes at foot strike, lowest vertical point of the pelvis and total range of hip motion during
a single leg drop landing.
Methodology-The study sample comprised 20 male club level soccer-and, rugby players, running and
cycling participants between the ages of 18-55 years of age. Ten of the subjects had
chronic groin pain and the other ten were healthy matched controls. An eight-camera Vicon system was used to analyse the kinematics of the hip joint during
single leg drop landing. For the purpose of comparison, the data was analysed for
participants with unilateral groin pain and matched controls (n=14) and participants with
bilateral groin pain and controls (n=6). The full set of data was subdivided for analysis into
three distinct sub-groups. Unilaterally injured groin cases (n=7) were matched with seven
healthy controls for analysis. Bilaterally injured groin cases (n=3) were matched with three
healthy controls. Results-Cases with unilateral groin pain at initial contact had significantly more abduction of the hip
joint when compared to controls (p<0.05). The effect size of this difference was large
(0.94). Cases with unilateral groin pain also demonstrated greater hip internal rotation
while the controls had external rotation (p<0.05) during a drop landing activity. Bilaterally
injured groin cases landed with significantly (p=?) greater ranges of hip flexion as well as
in significantly (p=?) more hip abduction during a drop landing activity. They also
demonstrated greater total range of motion in the frontal plan when compared to controls.
Groin pain cases overall demonstrated greater ranges of motion and tended to land in
more abduction compared to controls.
Conclusion-This study found that during a single leg drop landing, sports participants with unilateral
chronic groin pain landed with significantly greater hip abduction and exhibited larger total
range of motion in the transverse plane, which may indicate impaired stability of the hip
complex when compared to controls. / AFRIKAANSE OPSOMMING: Inleiding-Liesbeserings is een van die top ses mees prominente sokker beserings. Dit beloop 10-18
persent van alle beserings wat in kontaksport aangemeld word. Liespyn kan die gevolg
wees van ‘n verskeidenheid patologië, maar volgens die literatuur is 63 persent van
liespyn as gevolg adduktor patologie.
Doelwitte-Die doelwit van hierdie studie was om ondersoek in te stel of daar enige kinematiese
veranderinge in die heupgewrig is in spelers met liespyn in vergelyking met dieselfde
vergelykbare spelers sonder liespyn.
Studie Ontwerp-‘n Deursnit, beskrywende studie was onderneem.
Studie Omgewing-Die studie was uitgevoer by die FNB-3D bewegingsanalise laboratorium van die
Stellenbosch Universiteit, Suid-Afrika.
Uitkomsveranderlikes-Die afhanklike veranderlikes het in gesluit die heup kinematika in die sagitale, frontale en
transvers vlakke met voet kontak endie laagste vertikale punt van die pelvis sowel as die
totale heup omvang van beweging gedurende een been landing.
Metodologie-Die studie populasie het bestaan uit 20 manlike sokker- en, rugbyspelers, hardlopers en
fietsryers tussen die ouderdomme van 18 en 55 jaar. Tien van die deelnemers het
kroniese liespyn gehad en die ander tien in die gelyke gesonde groep was sonder liespyn.
Die agt kamera Vicon sisteem was gebruik om die kinematika van die heupgewrig te
analseer tydens een been landing. Vir die doel om ‘n vergelyking te kan maak, was die
data geanaliseer van deelnemers met unilaterale liespyn en die vergelykende groep
sonder liespyn (n=14) en deelnemers met bilaterale liespyn en hulle vergelykende groep
sonder liespyn (n=6).. Die volledige stel data was onderverdeel in drie afsonderlike sub
groepe. Vir die analiese was unilaterale liesbeserings (n=7) vergelyk met sewe
deelnemers sonder liespyn in die kontrolegroep. Deelnemers met bilaterale liesbeserings
(n=3) was vergelyk met drie in die kontrolegroep.
Resultate-Die deelnemers met unilaterale liespyn het met eerste kontak beduidend meer abduksie
van die heupgewrig gehad in vergelyking met die kontrolegroep (p<0.05). Die effek van
hierdie verskil was groot (0.94). Die deelnemers met unilaterale liespyn het ook ‘n grooter
interne rotasie getoon, terwyl die kontrole groep meer eksterne rotasie gedemonstreer het
(p<0.05) met landing. Deelnemers met bilaterale liespyn het beduidend (p=?) meer heup
fleksie en abduksie omvang van beweging tydens landing. Hulle het ook ‘n groter totale
heup omvang van beweging in die frontale vlak gehad in vergelyking met die
kontrolegroep. Deelnemers met liespyn het oor die algemeen ‘n grooter omvang van
beweging getoon, en was geneig om met meer abduksie van die heup te land as die
kontrolegroep.
Gevolgtrekking-Die studie toon dat deelnemers met kroniese unilaterale liespyn, tydens een been landing,
beduidende meerheup abduksie toon en dat die heup in die transverse vlak meer totale
omvang van beweging gebruik wat kan dui op onstabiliteit in die heupkompleks in
vergelyking met die kontrolegroep.
