Group-Based Individualized Comprehensive Core Stability Intervention Improves Balance in Persons With Multiple Sclerosis: A Randomized Controlled Trial.

ABSTRACT: BACKGROUND:Balance and trunk control are often impaired in individuals with multiple sclerosis (MS). Interventions addressing these issues are needed. OBJECTIVE:The objective of this study was to compare the immediate and long-term effects of a 6-week individualized, group-based, comprehensive core stability intervention (GroupCoreDIST) with standard care on balance and trunk control in individuals with MS. DESIGN:This study was a prospective, assessor-masked, randomized controlled trial. SETTING:The GroupCoreDIST intervention was conducted by 6 physical therapists in 6 municipalities in Norway. Standard care included the usual care for individuals with MS in the same municipalities. Assessments at all time points took place at a Norwegian hospital. PARTICIPANTS:Eighty people with Expanded Disability Status scores of 1 to 6.5 participated in this trial. INTERVENTION:Randomized, concealed allocation was used to assign the participants to the GroupCoreDIST intervention (n = 40) or to standard care (n = 40). The GroupCoreDIST intervention was conducted with groups of 3 participants (1 group had 4 participants), for 60 minutes 3 times per week. MEASUREMENTS:Assessments were undertaken at baseline and at weeks 7, 18, and 30. Outcomes were measured with the Trunk Impairment Scale-Norwegian Version, Mini Balance Evaluation Systems Test, and Patient Global Impression of Change-Balance. Repeated-measures mixed models were used for statistical analysis. RESULTS:One individual missed all postintervention tests, leaving 79 participants in the intention-to-treat analysis. GroupCoreDIST produced significant between-group effects on the mean difference in the following scores at 7, 18, and 30 weeks: for Trunk Impairment Scale-Norwegian Version, 2.63 points (95% confidence interval [CI] = 1.89-3.38), 1.57 points (95% CI = 0.81-2.33), and 0.95 point (95% CI = 0.19-1.71), respectively; for Mini Balance Evaluation Systems Test, 1.91 points (95% CI = 1.07-2.76), 1.28 points (95% CI = 0.42-2.15), and 0.91 points (95% CI = 0.04-1.77), respectively; and for Patient Global Impression of Change-Balance, 1.21 points (95% CI = 1.66-0.77), 1.02 points (95% CI = 1.48-0.57), and 0.91 points (95% CI = 1.36-0.46), respectively. LIMITATIONS:Groups were not matched for volume of physical therapy. CONCLUSIONS:Six weeks of GroupCoreDIST improved balance and trunk control in the short and long terms compared with standard care in individuals who were ambulant and had MS. The intervention is an effective contribution to physical therapy for this population.

Project description:The standard functional tool for gait assessment in multiple sclerosis (MS) clinical trials has been the 25-Foot Timed Walk Test, a measure of gait speed. Straight-line gait assessment may not reflect adequately upon balance and coordination. Walking tests with turns may add additional information towards understanding gait and balance status, and be more reflective of ambulation in the community. Understanding the impact of turn parameters on patient-reported outcomes of balance and walking would help MS clinicians better formulate treatment plans for persons with gait limitations. In this study, ninety-one persons with MS (Expanded Disability Status Score; EDSS, range: 0-6.5) were enrolled in an initial cross-sectional study. Twenty-four subjects (EDSS, range:1.0-6.0) completed a follow-up visit an average of 12 months later. Spatiotemporal gait analysis was collected at both visits using APDM Opal wireless body-worn sensors while performing the Timed-Up-and-Go (TUG) and 6-Minute Walk Test (6MWT). For both cross-sectional and longitudinal data, regression analyses determined the impact on the addition of turning parameters to stride velocity (SV), in the prediction of self-reported balance confidence (Activities-Specific Balance Confidence Scale (ABC)) and walking limitation (12-item Multiple Sclerosis Walking Scale (MSWS-12)). The addition of 6MWT peak turn velocity (PTV) to 6MWT SV increased the predictive power of the 6MWT for the ABC from 20% to 33%, and increased the predictive power from 28% to 41% for the MSWS-12. TUG PTV added to TUG SV also strengthened the relationship of the TUG for the ABC from 19% to 28%, and 27% to 36% for the MSWS-12. For those with 1 year follow-up, percent change in turn number of steps (TNS%Δ) during the 6MWT added to 6MWT SV%Δ improved the modeling of ABC%Δ from 24% to 33%. 6MWT PTV%Δ added to 6MWT SV%Δ increased the predictive power of MSWS-12%Δ from 8% to 27%. Conclusively, turn parameters improved modeling of self-perceived balance confidence and walking limitations when added to the commonly utilized measure of gait speed. Tests of longer durations with multiple turns, as opposed to shorter durations with a single turn, modeled longitudinal change more accurately. Turn speed and stability should be qualitatively assessed during the clinic visit, and use of multi-faceted tests such as the TUG or 6MWT may be required to fully understand gait deterioration in persons with MS.

Project description:ObjectiveKnowledge about determinants of participation in lifestyle interventions in cancer patients undergoing chemotherapy, particularly with palliative intent, remains poor. The objective of the present study was to identify determinants of participating in a 12 month individualized, comprehensive lifestyle intervention, focusing on diet, physical activity, mental stress and smoking cessation, in cancer patients receiving chemotherapy with curative or palliative intent. The secondary objective was to identify participation determinants 4 months into the study.MethodsNewly diagnosed cancer patients starting chemotherapy at the cancer center in Kristiansand/Norway (during a 16 month inclusion period) were screened. Demographic and medical data (age, sex, body mass index, education level, marital status, smoking status, Eastern Cooperative Oncology Group performance status (ECOG), diagnosis, tumor stage and treatment intention) was analyzed for screened patients.Results100 of 161 invited patients participated. There were more females (69 vs. 48%; P = 0.004), breast cancer patients (46 vs. 25%; P = 0.007), non-smokers (87 vs. 74%; P = 0.041), younger (mean age 60 vs. 67 yrs; P < 0.001) and fitter (82 vs. 64% with EGOC 0; P = 0.036) participants vs. non-participants included. In multivariate logistic regression analyses, age (Odds Ratio 0.94, 95% Confidence Interval 0.91, 0.97) and smoking (0.42, 0.18, 0.99) were negatively associated with participation. After 4 months, 63 participants were still participating. Cancer type, smoking and age increased the probability of dropping out. Multivariate logistic regression revealed that age was the only significant determinant of 4 month participation (0.95, 0.91, 0.99). Patients aged >70 years were less likely to participate at baseline and 4 months.ConclusionIndividualized lifestyle interventions in cancer patients undergoing chemotherapy appear to facilitate a high participation rate that declines with increasing age; both during the enrollment process and completing the intervention. Neither oncologic nor socioeconomic variables deterred participation.
