Determinants of dietary behaviour in wheelchair users with spinal cord injury or lower limb amputation: Perspectives of rehabilitation professionals and wheelchair users.

OBJECTIVE: This study aims to identify determinants of dietary behaviour in wheelchair users with spinal cord injury or lower limb amputation, from the perspectives of both wheelchair users and rehabilitation professionals. The findings should contribute to the field of health promotion programs for wheelchair users. METHODS: Five focus groups were held with wheelchair users (n = 25), and two with rehabilitation professionals (n = 11). A thematic approach was used for data analysis in which the determinants were categorized using an integrated International Classification of Functioning, Disability and Health and Attitude, Social influence and self-Efficacy model. RESULTS: Reported personal factors influencing dietary behaviour in wheelchair users were knowledge, boredom, fatigue, stage of life, habits, appetite, self-control, multiple lifestyle problems, intrinsic motivation, goal setting, monitoring, risk perception, positive experiences, suffering, action planning, health condition, function impairments, attitude and self-efficacy. Reported environmental factors influencing dietary behaviour in wheelchair users were unadjusted kitchens, monitoring difficulties, eating out, costs, unfavourable food supply, nutrition education/counselling, access to simple healthy recipes, eating together, cooking for others, and awareness and support of family and friends. CONCLUSIONS: Important modifiable determinants of dietary behaviour in wheelchair users that might be influenced in lifestyle interventions are knowledge, fatigue, habits, self-control, intrinsic motivation, risk perception, attitude and self-efficacy. It is recommended to involve relatives, since they appear to significantly influence dietary behaviour.

Determinants of physical activity in wheelchair users with spinal cord injury or lower limb amputation: perspectives of rehabilitation professionals and wheelchair users.

Purpose: To gain insight into determinants of physical activity in wheelchair users with spinal cord injury or lower limb amputation, from the perspective of both wheelchair users and rehabilitation professionals.Methods: Seven focus groups were conducted: five with wheelchair users (n = 25) and two with rehabilitation professionals (n = 11). The transcripts were analysed using a sequential coding strategy, in which the reported determinants of physical activity were categorized using the Physical Activity for people with a Disability (PAD) model.Results: Reported personal determinants of physical activity were age, general health status, stage of life, demotivation due to difficulty burning calories, available time and energy, balance in daily life, attitude, and history of a physically active lifestyle. Reported environmental determinants were professional guidance, inconvenient exercise times, accessibility of facilities, costs, transportation difficulties, equipment difficulties, and social support.Conclusions: Important, changeable determinants of physical activity that might be influenced in future lifestyle interventions for wheelchair users are: balance in daily life leading to more time and energy to exercise, attitude towards physical activity, professional guidance, accessibility of facilities (providing information on how and where to find accessible facilities), and social support (learning how to get this).Implications for rehabilitationA physically active lifestyle improves everyday functioning, and decreases disability and the risk of secondary health problems in wheelchair users with spinal cord injury or lower limb amputation.After inpatient rehabilitation, it is difficult for wheelchair users to maintain or further enhance their physical activity, a lifestyle intervention can help them in this.To be effective, lifestyle interventions should address important, changeable determinants of physical activity.Important, changeable determinants of physical activity reported by wheelchair users and rehabilitation professionals are: balance in daily life leading to more time and energy to exercise, attitude towards physical activity, professional guidance, accessibility of facilities, and social support.

The 2-minute walk test is not a valid method to determine aerobic capacity in persons with Multiple Sclerosis.

BACKGROUND: Walking tests, like the 2-minute fast walk test, are simple, inexpensive performance-based tests, and therefore seem attractive to estimate the aerobic fitness in people with chronic diseases. OBJECTIVE: To determine the criterion validity of the 2-minute fast walk test for estimating aerobic capacity in patients with Multiple Sclerosis (MS), by comparing it with the peak oxygen uptake (VO2peak in mL/kg/min) as measured by Cardiopulmonary Exercise Testing (CPET) on a cycle ergometer. METHODS: The 2 min fast walk test was performed on a marked indoor trajectory, using a static start protocol. Aerobic capacity (VO2peak, in mL/kg/min) was derived from CPET on a cycle ergometer. Criterion validity was tested by means of Pearson's correlation coefficient and should be at least 0.70 for a good criterion validity of the 2 min walk test. Linear regression analysis was applied to more precisely estimate VO2peak. RESULTS: In total 141 people with severe MS-related fatigue (mean age 47.0 years (range 23-68 years), 73% women, median disease duration 7.8 years (range 0.3 - 28.7 years)) performed both tests. The distance walked in two minutes ranged from 52.0 to 290.0 m (mean 175.1 m, sd 44.9 m), while the VO2peak varied between 11.31 and 40.28 mL/kg/min (mean 22.52 mL/kg/min, sd 6.07 mL/kg/min). The correlation between the 2 min walk test and VO2peak was 0.441 (95% CI: 0.309-0.570). The absolute residual error in estimated VO2peak was 5.47 mL/kg/min. CONCLUSIONS: Due to the poor correlation found between the 2 min walk test and VO2peak, the 2-min walk test cannot be recommended as a valid alternative for estimating aerobic capacity in persons with MS.

Cognitive behavioral therapy positively affects fatigue in patients with multiple sclerosis: Results of a randomized controlled trial.

BACKGROUND: Fatigue is a common symptom in multiple sclerosis (MS) and often restricts societal participation. Cognitive behavioral therapy (CBT) may alleviate MS-related fatigue, but evidence in literature is inconclusive. OBJECTIVE: To evaluate the effectiveness of CBT to improve MS-related fatigue and participation. METHODS: In a multi-center, assessor-masked, randomized controlled trial, participants with severe MS-related fatigue were assigned to CBT or control treatment. CBT consisted of 12 individual sessions with a psychologist trained in CBT, the control treatment consisted of three consultations with a MS nurse, both delivered over 16 weeks. Assessments were at baseline, 8, 16 (i.e. post-intervention), 26, and 52 weeks post-baseline. Primary outcomes were the Checklist Individual Strength-fatigue subscale (CIS20r fatigue) and the Impact on Participation and Autonomy questionnaire (IPA). Data were analyzed according to the intention-to-treat principle, using mixed-model analysis. RESULTS: Between 2011 and 2014, 91 patients were randomized (CBT: n = 44; control: n = 47). Between-group analysis showed a positive post-intervention effect for CBT on CIS20r fatigue (T16: -6.7 (95% confidence interval (CI) = -10.7; -2.7) points) that diminished during follow-up (T52: 0.5 (95% CI = -3.6; 4.4)). No clinically relevant effects were found on societal participation. CONCLUSION: Severe MS-related fatigue can be reduced effectively with CBT in the short term. More research is needed on how to maintain this effect over the long term.
