This research project focuses on age as a predictor in the emotional adjustment of a spouse following his/her partner's stroke. The medical records of 80 stroke cases were reviewed at Kaiser Permanente Medical Center, Fontana, California. Patients and spouses were examined in two age groupings, age 55 and below, and ages 56 and above. Study of these two age groups afforded the most meaningful division to study spouse adjustment.

Upper limb (UL) impairments are common after stroke and can lead to loss of independence and long-term disability. Motor learning interventions for individuals with stroke can improve UL function and engagement in daily activities. Self-controlled practice (SCP) involves allowing choice during motor skill practice and has been shown to improve motor learning in healthy adults as well as individuals with Parkinson's disease. Additionally, SCP may impact psychological outcomes, including intrinsic motivation, self-efficacy, and positive affect. Although SCP has been incorporated into complex stroke rehabilitation interventions, little is known about its specific impact on motor learning for individuals with stroke. The purpose of this study is to investigate the effect of SCP on motor learning and psychological outcomes for adults with chronic UL impairment after stroke. Sixteen participants with chronic UL impairment due to stroke were paired and randomized into two groups. All participants practiced a standardized motor task with both their more affected and less affected hands for two consecutive days. During each day of practice, participants completed 50 30-second trials (10 blocks of 5 trials each) with their more affected hand and 20 30-second trials (10 blocks of 2 trials each) with their less affected hand. The experimental group was given control over their practice schedule and chose the order they practiced blocks of trials. Participants in the control group followed a pre-determined practice schedule based on the choices made by the participant they were paired with in the experimental group. Outcome measures were assessed on Day 1 before practice (Pre-Test), Day 2 after practice (Post-Test), and Day 3 (Follow-up). Motor learning outcomes included 24-hour retention of the trained motor task and immediate (10-minute) and delayed (24-hour) transfer of learning to an untrained motor task. Psychological outcomes including intrinsic motivation, self-efficacy, and positive affect were also assessed. Both groups demonstrated significant improvements from baseline on both the trained task and the untrained task at the Day 3 follow-up assessment. There were no significant between-group differences on any motor learning or psychological outcome measures. However, there was a significant association between perceived choice that was assessed on Day 2 following practice and amount of change on the untrained transfer task at Day 3. This suggests that perception of choice may be a relevant factor for motor learning after stroke. However, more research with larger sample sizes is needed to further investigate this finding.

Thesis (MSportSc)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: There are a growing number of men and women world-wide who are suffering strokes due to poor lifestyle-related habits. While there is evidence of the differences in cerebral haemodynamics between stroke patients and both elderly and young healthy individuals, limited evidence has examined the effect of rehabilitation on cerebral haemodynamics. Furthermore, most studies have examined changes in cerebral haemodynamics during cognitive and functional tasks in isolation, with no literature published on them simultaneously. The primary aim of this study was to examine whether differences in cerebral haemodynamics exist between stroke patients and healthy elderly individuals while performing a simple and complex cognitive task. Thirty two men and women (age 75 ± 8 years) volunteered to participate in the study and were split into an experimental (n = 14) group consisting of stroke patients and a control (n = 18) group consisting of healthy individuals. Each participant was required to attend one testing session where measurements of oxyhaemoglobin (O2Hb), deoxy-haemoglobin (HHb), tissue oxygenation index (TOI) and total haemoglobin index (THI) were obtained. Measurements were obtained with the participants at rest, while performing the Mini Mental State Exam (MMSE) and the modified Stroop Task as cognitive tests, and the Timed Up-and-Go (TuG) and six minute walk test (6MWT) or Toe Taps (TT) as the functional tests. Furthermore, the outcome scores of the various tests were also recorded. Change in O2Hb levels were lower in the experimental group than in the control group, especially in the left prefrontal cortex (LPFC) while HHb values were higher in the right prefrontal cortex (RPFC) (p > 0.05). There were almost no differences in TOI between the two groups in either the LPFC or RPFC, however, statistically significant differences were seen in THI in the RPFC during the MMSE (p = 0.03), rest period 2 (p = 0.03), the first modified Stroop Task (p = 0.04), as well as the TuG (p = 0.02). Furthermore, significant differences were seen between the two groups with respect to the time taken to complete the TuG, with the experimental group completing it much faster (p = 0.04). The experimental group participants who had received regular rehabilitation performed consistently better across most of the testing phases, with a number of practically significant findings. The results show that definite differences exist between stroke patients and healthy elderly individuals when performing a simple and complex task. The positive effect of low intensity exercise on task performance was clearly seen in both groups, and holds a great deal of practical significance for the development of exercise programmes for healthy individuals, as well as stroke patients. Furthermore, rehabilitation following a stroke has obvious benefits as shown by the positive results of the current study, however, limited research exists to validate these findings, highlighting the need for further research in this area. / AFRIKAANSE OPSOMMING: Daar is ʼn wêreld wye toename in die aantal mans en dames wat beroertes ondervind as gevolg van swak lewenstyl-verwante gewoontes. Alhoewel baie navorsing beskikbaar is oor die verskille in serebrale hemodinamika tussen beroerte pasiënte en bejaardes, asook jong gesonde individue, is daar ʼn beperkte aantal studies oor die effek van rehabilitasie op serebrale hemodinamika. Meeste van hierdie studies het die veranderinge in serebrale hemodinamika tydens kognitiewe of funksionele take in isolasie ondersoek, met geen literatuur waar die effek van albei gesamentlik gemeet word nie. Die hoofdoel van hierdie studie was om die verskille in serebrale hemodinamika tussen beroerte pasiënte en gesonde bejaardes, tydens die uitvoering van ʼn eenvoudige en komplekse kognitiewe taak, te ondersoek. Twee-en-dertig mans en vroue (ouderdom 75 ± 8 jaar) het aan die studie deelgeneem. Die eksperimentele groep (n = 14) het bestaan uit die beroerte pasïente en die kontrole groep (n = 18) was gesonde bejaardes. Elke deelnemer het een toets sessie bygewoon waartydens oksihemoglobien (O2Hb), deoksihemoglobien (HHb), weefsel oksigenasie indeks (TOI) en totale hemoglobien indeks (THI) gemeet is. Metings is tydens rus geneem, asook tydens die kognitiewe toetse, die “Mini Mental State Exam” (MMSE) en die gewysigde Stroop taak gemeet, en die funksionele toetse, naamlik die “Timed Up-and-Go” (TuG) en die ses minute loop toets (6MWT) of “Toe Taps” (TT). Die eksperimentele groep se O2Hb was laer as die kontrole groep, veral in die linker voor frontale korteks (LPFC), en die eksperimentele groep se HHb waardes was hoër in die regter voor frontale korteks (RPFC) (p > 0.05). Daar was geen statisties betekenisvolle verskille in TOI tussen die twee groepe nie, maar wel in die THI in die RPFC tydens die MMSE (p = 0.03), rusperiode twee (p = 0.03), die eerste gewysigde Stroop Taak (p = 0.04) en die TuG toets (p = 0.02). Die kontrole groep was statisties betekenisvol vinniger as die eksperimentele groep in die TuG toets (p = 0.04). Deelnemers in die eksperimentele groep wat gereelde rehabilitasie ontvang het, het konsekwent beter gevaar tydens die toets sessie, en ʼn aantal prakties betekenisvolle verskille is in sekere veranderlikes gevind. Die resultate dui aan dat daar wel ʼn verskil in serebrale hemodinamika bestaan tussen beroerte pasiënte en gesonde bejaardes terwyl hulle eenvoudige en komplekse take verrig. Die positiewe effek van lae intensiteit oefening op prestasie was duidelike sigbaar van beide groepe. Hierdie resultate is prakties betekenisvol as dit kom by die ontwikkeling van oefenprogramme vir gesonde individue asook beroerte pasiënte. Rehabilitasie na ʼn beroerte hou ooglopende voordele in soos aangedui deur die positiewe bevindinge van die huidige studie, hoewel daar beperkte navorsing beskikbaar is om hierdie bevindinge te staaf. Daar is dus ʼn behoefte vir verdere navorsing in hierdie gebied.

Stroke outcome is highly variable. Experiments in this thesis test the hypothesis that experience prior to a stroke is an important variable in the manifestation of stroke. Optokinetic tracking was used to evaluate the effects of visual cortex stroke and MCA occlusion in rats. Normal laboratory rats showed a small, but significant decrease in tracking thresholds following visual cortex stroke. Animals with developmental visuomotor experience or reach training experience in adulthood, however, had tracking thresholds which were substantially increased, and the effects of visual cortex strokes were greater. MCA occlusions did not affect tracking behaviour. These data indicate that specific experiences engage neural plasticity that can alter brain function. These changes can, in turn, affect the behavioural manifestation of a stroke. Understanding the effect that environmental experience has on stroke outcome promises to enable better characterization of strokes, and set appropriate behavioural baselines for the measurement of recovery of function. / vi, 135 p. : ill. ; 29 cm

Stress has been shown to exacerbate cell death and cognitive deficits after ischemic injury in rodents, however, little is known of the effects of stress on motor recovery. The objective of this present thesis is to examine the effects of chronic stress on skilled motor recovery after devascularization lesion in rats. It was found that pre-lesion stress induced the most behavioural impairments, while post-lesion stress exacerbated infarct volume. The effects of chronic multiple stress on skilled motor recovery after lesion was also examined. Chronic multiple stress did not modulate skilled motor recovery nor did it have any influence on infarct volume. Additionally, stress had effect on edema after devascularization lesion. The present thesis suggests that the time of exposure to chronic stress in respect to the ischemic lesion, in addition to the type of stress, will differentially affect recovery and compensation in rats. / xii, 122 leaves : ill. ; 29 cm.
