Spine and pelvis coupled movements in the frontal plane during inclined walking and runningAbbatt, Joanna. January 2000 (has links)
Spinal adaptive response in the frontal plane was investigated in relationship to pelvic unleveling during gait. Kinematic data were collected from 10 healthy adult subjects (5 male, 5 female) for walking and running on the treadmill at self-selected speeds. Spine and pelvic kinematic patterns and ranges of motion (ROM) were investigated with gender, speed and slope as factors. Speed and slope had the greatest impact on changes in the amplitude of the spine's kinematic patterns. Interaction effects were seen for speed and slope for the ROM, particularly of the greater trochanter (p < .047), PSIS (p < .011) and for the shoulders (p < 0.077). Gender presented more changes in the pelvic kinematics than the spine's kinematics. A significant trend in the females of greater ROM for T8 with increases in speed and slope was shown (p < 0.001). From this study it was concluded that speed, slope and gender were significant factors that affect the spine's ability to adapt to pelvic unleveling. In all conditions there was a coupled relationship found between the thoracic spine, lumbar spine and pelvis. In particular there was an oppositional movement found within the spine such that as the lumbar spine had convexity towards the swing leg then the thoracic spine had the opposite convexity. Hence, these factors are important when assessing posture and biomechanics of running and walking.

Investigation of thoracic spine kinematics in adult sports participants with chronic groin pain during a single leg drop landing taskMorris, Tracy Louise 04 1900 (has links)
Thesis (MScPhysio)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Chronic groin pain is widespread across many sporting disciplines. The aim of our
research was to determine if there are kinematic differences of the thoracic spine in
active sports people with chronic groin pain, compared with healthy controls. A
cross-sectional descriptive design was followed. Participants were required to
complete six single leg drop landings with each leg from a 20cm height.
The study was done in the 3D Movement Analysis Laboratory at the University of
Stellenbosch. Ten male participants with unilateral or bilateral chronic groin pain of
more than 3 months duration and 10 asymptomatic males, matched for age and
sports participation, were recruited.
The main outcome measures were: thoracic spine angle at initial foot contact,
maximum thoracic spine angle, range of movement (ROM) (difference between the
minimum and maximum values) and thoracic spine angle at lowest vertical point of
the pelvis. This was assessed in all 3 movement planes: the sagittal plane (X plane),
the coronal plane (Y plane) and the transverse plane (Z plane). The results of our study showed that for the unilaterally affected groin pain group, the
cases landed in significantly more thoracic flexion (P<0.001 with large effect size)
and were in significantly more thoracic flexion still at the lowest point. Peak thoracic
flexion was significantly more in the cases than the controls. (P<0.001 with medium
effect size) The same was true for the bilaterally affected group when landing on the
most painful side, although this was not statistically significant. There were no
significant differences in the frontal or transverse planes. In the bilaterally painful
group, axial rotation ROM was significantly reduced when landing on either leg
(worst affected side: P=0.040 with medium effect size and least affected side: p=0.006 with large effect size). The same occurred in the unilaterally affected group,
although this was not statistically significant.
Our study suggests that, in participants with chronic groin pain, there is greater
thoracic forward flexion away from neutral during landing and that total axial rotation
ROM during landing is diminished. / AFRIKAANSE OPSOMMING: Kroniese liespyn kom dikwels en in verskeie sportsoorte voor. Die doel van ons
studie was om te bepaal of daar kinematiese verskille van die torakale werwelkolom
is in aktiewe sportmense met chroniese liespyn, in vergelyking met gesonde
kontroles. ‘n Dwars-deursnit beskrywende studiemetode is gevolg, en uitgevoer in
die 3D Beweging Analise Laboratorium, Universiteit van Stellenbosch. Deelnemers
moes ses landings op een been doen, met elke been, vanaf 'n 20cm hoogte. Tien
mans met eensydige of bilaterale chroniese liespyn vir langer as 3 maande, en 10
asimptomatiese mans (ooreenstemmende ouderdom en sport deelname) het
deelgeneem. Die hoof uitkomste wat gemeet is, was torakale werwelkolom
krommingshoek by aanvanklike voet-kontak, maksimum torakale werwelkolom
krommingshoek, omvang van beweging (OVB) (verskil tussen die minimum en
maksimum waardes) en torakale werwelkolom krommingshoek by die laagste punt
van die bekken. Dit is beoordeel in al 3 beweging vlakke: die sagittale (X) vlak, die
koronale/frontale (Y) vlak en die transversale (Z) vlak. Die resultate van die studie het getoon dat, in die eensydig-geaffekteerde liespyn
groep, die deelnemers in beduidend meer torakale fleksie geland het(P < 0.001, met
'n groot effekgrootte), asook met aansienlik meer torakale fleksie by die laagste punt
na landing. Piek torakale fleksie was aansienlik meer in die liespyn-gevalle as in die
kontroles. (P < 0.001, met middelmatige effekgrootte ) Dieselfde het vir die bilateraalgeaffekteerde
groep gegeld wanneer hulle op hul mees pynlike kant geland het,
hoewel dit nie statisties beduidend was nie. Daar was geen betekenisvolle verskille
in die frontale of transversale vlakke van beweging nie. In die bilateraal pynlike
groep, was aksiale rotasie OVB aansienlik verminder wanneer die gevalle op hul
pynlikste been óf op hul minder pynlike been geland het ( mees pynlike been : P = 0,040, met 'n middelmatige effekgrootte en minder pynlike been : p = 0,006, met 'n
groot effekgrootte ). Dieselfde het in die eensydig-geaffekteerde groep gebeur,
hoewel dit nie statisties beduidend was nie.
Ons studie dui daarop dat, in deelnemers met chroniese liespyn, daar meer torokale
fleksie weg van neutraal tydens landing is en dat die totale aksiale rotasie OVB
tydens die landing verminder is, in vergelyking met die kontrolegroep.

Investigation of hip kinematics in adult sports participants during single leg drop landing with chronic groin painDare, Michael Robert 04 1900 (has links)
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.
