dc.description.abstractENGLISH ABSTRACT: Objectives: The objective of this study was to describe the differences in vertical ground reaction forces (VGRF) in male sports participants with adductor-related groin pain, compared to matched asymptomatic controls. Design: A descriptive observational study with cross-sectional time frame was conducted. Setting: Laboratory based setting at the 3D Human Biomechanics Central Analytical Facility were implemented. Participants: A consecutive sample of twenty-six active male sports participants, thirteen subjects with adductor-related groin pain (unilateral and bilateral) and thirteen matched asymptomatic controls were included. Main Outcome Measures: Three outcome measures were used: time to peak landing force, peak landing force and time to lowest vertical position of the pelvis. Results: Greater differences were seen in time to peak landing force and peak landing force in the unilateral pain group versus the matched controls. No statistical or clinical differences were found in either of the three outcome measures (p>0.05) between the subjects and their matched controls. Conclusions: This study demonstrates similar VGRFs between subjects with and without chronic adductor-related groin pain and that changes in VGRF might not result from adductor-related groin pain. Clinically, teaching appropriate landing strategies to decrease VGRF may not be useful in male sports participants with chronic adductor-related groin pain.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Doel: Die doel van hierdie studie was om veranderinge in vertikale grond reaksie-kragte (VGRK) te bepaal in manlike sport deelnemers met adduktor-verwante liespyn en dit te vergelyk met ‘n nie-symptomatiese kontrole groep. Ontwerp: ‘n Beskrywende waarnemeingstudie is uitgevoer. Omgewing: Labratorium-gebaseerde studie by die 3D Menslike Biomeganika sentrale analiserings fasiliteit is geimplementeer. Deelnemers: ‘n Groep van ses-en-twintig aktiewe manlike sport deelnemers is agtereenvolglik gewerf. Die groep het bestaan uit dertien deelnemers (unilaterale en bilaterale) met adduktor-verwante liespyn en dertien ooreenstemmende, nie-simptomatiese kontroles. Uitkomsmetings: Drie uitkomsmetings was gebruik: tyd tot pieklandingskrag, pieklandingskrag en tyd tot die laagste vertikale posisie van die pelvis. Resultate: Groter verskille is waargeneem in tyd tot pieklandingskrag en pieklandingskrag in die unilateral pyn groep in vergelyking met die ooreenstemmende kontrole groep. Geen statistiese of kliniese verskille is gevind tussen die twee groepe in enige van die drie uitkomsmetings nie (p>0.05). Gevolgtrekking: Hierdie studie toon ooreenstemmende VGRK tussen deelnemers met en sonder adduktor-verwante liespyn en dat veranderinge in VGRK moontlik nie ‘n resultaat is van adduktor-verwante liespyn nie. Klinies impliseer dit dat die aanleer van effektiewe landings stratigieë om VGRK te verminder nie van waarde mag wees in manlike sportdeelnemers met adduktor-verwante lies pyn nie.af_ZA
