Efficacy of a physical activity programme combining individualized aerobic exercise and coaching to improve physical fitness in neuromuscular diseases (I'M FINE): study protocol of a randomized controlled trial.

BACKGROUND: In individuals with neuromuscular diseases (NMD), symptoms of muscle weakness, fatigue and pain may limit physical activity. Inactivity leads to reduced physical fitness, which further complicates daily life functioning. Due to inconclusive evidence regarding exercise in NMD, the optimal training approach and strategies to preserve an active lifestyle remain to be determined. The physical activity programme I'M FINE, consisting of individualized aerobic exercise to improve physical fitness and coaching to preserve an active lifestyle, was therefore developed. The primary objective of this study will be to evaluate the efficacy of the I'M FINE programme in terms of improved physical fitness in individuals with slowly progressive NMD, compared to usual care. METHODS: A multicentre, assessor-blinded, two armed, randomized controlled trial will be conducted in a sample of 90 individuals with slowly progressive NMD. Participants motivated to improve their reduced physical fitness will be randomized (ratio 1:1) to the I'M FINE intervention or usual care. The I'M FINE intervention consists of a six-month physical activity programme, including individualized home-based aerobic exercise to improve physical fitness (i.e. peak oxygen uptake), and motivational interviewing coaching (e.g. goal setting, self-management) to adopt and preserve an active lifestyle. Measurements will be performed at baseline, post-intervention, and at 12- and 18-months follow-up. The primary outcome is peak oxygen uptake (VO2 peak) directly post intervention. Main secondary outcomes are physical capacity, muscle strength, self-efficacy, daily activity, quality of life and markers of metabolic syndrome. The primary analysis compares change in VO2 peak post-intervention between the intervention and usual care group, with analysis of covariance. DISCUSSION: The I'M FINE study will provide evidence regarding the efficacy of a physical activity intervention on the physical fitness and active lifestyle over the short- and long-term in individuals with slowly progressive NMD. These outcomes could potentially improve the (inter)national guidelines for efficacy of aerobic exercise programmes and provide insight in achieving a more active lifestyle in NMD.

Caregiver burden in amyotrophic lateral sclerosis: A systematic review.

BACKGROUND: Informal caregivers of patients with amyotrophic lateral sclerosis experience increased levels of caregiver burden as the disease progresses. Insight in the factors related to caregiver burden is needed in order to develop supportive interventions. AIM: To evaluate the evidence on patient and caregiver factors associated with caregiver burden in amyotrophic lateral sclerosis informal caregivers. DESIGN: A systematic review. DATA SOURCES: Four electronic databases were searched up to 2017. Studies that investigated quantitative relations between patient or caregiver factors and caregiver burden were included. The overall quality of evidence for factors was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: A total of 25 articles were included. High quality of evidence was found for the relation between caregiver burden and the factor "behavioral impairments." Moderate quality of evidence was found for the relations between caregiver burden and the factors "feelings of depression" of the caregiver and "physical functioning" of the patient. The remaining rated caregiver factors-"feelings of anxiety," "distress," "social support," "family functioning," and "age"-and patient factors-"bulbar function," "motor function," "respiratory function," "disease duration," "disinhibition," "executive functioning," "cognitive functioning," "feelings of depression," and "age"-showed low to very low quality of evidence for their association with caregiver burden. CONCLUSION: Higher caregiver burden is associated with greater behavioral and physical impairment of the patient and with more depressive feelings of the caregiver. This knowledge enables the identification of caregivers at risk for caregiver burden and guides the development of interventions to diminish caregiver burden.

Participation restrictions in ambulatory amyotrophic lateral sclerosis patients: Physical and psychological factors.

INTRODUCTION: The aim of this study was to assess the prevalence of participation restrictions in ambulatory patients with amyotrophic lateral sclerosis (ALS) and to identify physical and psychological contributory factors. METHODS: In this cross-sectional study, self-reported participation restrictions of 72 ambulatory ALS patients were assessed using the social health status dimension (SIPSOC) of the Sickness Impact Profile (SIP-68). Associations between SIPSOC and physical functioning, psychological factors, and demographic factors were analyzed using hierarchical regression analyses. RESULTS: Ninety-two percent of the patients reported participation restrictions; 54.9% could be explained by physical functioning; psychological factors accounted for 8.1% of the variance. Lung capacity, functional mobility, fatigue, and helplessness were independently associated with participation restrictions. CONCLUSIONS: Ambulatory ALS patients have participation restrictions, which may be influenced if early ALS care is directed toward lung capacity, functional mobility, fatigue, and feelings of helplessness.

Associations between psychological factors and health-related quality of life and global quality of life in patients with ALS: a systematic review.

OBJECTIVE: To systematically identify and appraise evidence on associations between psychological factors (moods, beliefs, personality) and Health-related QoL (HRQoL) and/or global QoL in patients with Amyotrophic Lateral Sclerosis (ALS). METHODS: A systematic review was conducted in several online databases (PsycINFO, EMBASE, PubMed and CINAHL) up to October 2015. Articles were included if they reported associations between psychological factors (moods, beliefs and personality) and HRQoL and/or global QoL in an ALS population. The search was limited to empirical studies, published in English, which provided quantitative data. The methodological quality of the included articles was assessed. RESULTS: In total, 22 studies were included. Mood was investigated in 14 studies, beliefs in 11 studies and personality in one study. Fifteen different psychological factors were extracted and assessed using 24 different measures. Twelve different QoL measures were used in the selected studies, subdivided into seven different HRQoL measures and five different global QoL measures. Higher levels of anxiety and depression appeared to be related to a poorer HRQoL, whereas a higher level of religiosity seemed to be associated with better global QoL. No conclusive associations were found for confusion-bewilderment (mood), spirituality, mindfulness, coping styles, hopelessness, perception of burden, cognitive appraisal (beliefs), neuroticism, extraversion, openness, agreeableness and conscientiousness (personality), due to insufficient or inconsistent evidence. Religiosity and spirituality appeared to become more positively associated over time. CONCLUSIONS: Our results suggest that higher levels of anxiety and depression are related to a poorer HRQoL, whereas higher levels of religiosity appeared to be related to better global QoL. Associations might change during the disease course. This review supports the importance of psychological factors with regard to ALS care. Further research is needed to supplement the available evidence and to investigate how psychological factors can be modified to improve QoL. REVIEW REGISTRATION NUMBER: PROSPERO 2015:CRD42015027303.

Effects of aerobic exercise therapy and cognitive behavioural therapy on functioning and quality of life in amyotrophic lateral sclerosis: protocol of the FACTS-2-ALS trial.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a fatal progressive neurodegenerative disorder affecting motor neurons in the spinal cord, brainstem and motor cortex, leading to muscle weakness. Muscle weakness may result in the avoidance of physical activity, which exacerbates disuse weakness and cardiovascular deconditioning. The impact of the grave prognosis may result in depressive symptoms and hopelessness. Since there is no cure for ALS, optimal treatment is based on symptom management and preservation of quality of life (QoL), provided in a multidisciplinary setting. Two distinctly different therapeutic interventions may be effective to improve or preserve daily functioning and QoL at the highest achievable level: aerobic exercise therapy (AET) to maintain or enhance functional capacity and cognitive behavioural therapy (CBT) to improve coping style and cognitions in patients with ALS. However, evidence to support either approach is still insufficient, and the underlying mechanisms of the approaches remain poorly understood. The primary aim of the FACTS-2-ALS trial is to study the effects of AET and CBT, in addition to usual care, compared to usual care alone, on functioning and QoL in patients with ALS. METHODS/DESIGN: A multicentre, single-blinded, randomized controlled trial with a postponed information model will be conducted. A sample of 120 patients with ALS (1 month post diagnosis) will be recruited from 3 university hospitals and 1 rehabilitation centre. Patients will be randomized to one of three groups i.e. (1) AET + usual care, (2) CBT + usual care, (3) Usual care. AET consists of a 16-week aerobic exercise programme, on 3 days a week. CBT consists of individual psychological support of patients in 5 to 10 sessions over a 16-week period. QoL, functioning and secondary outcome measures will be assessed at baseline, immediately post intervention and at 3- and 6-months follow-up. DISCUSSION: The FACTS-2-ALS study is the first theory-based randomized controlled trial to evaluate the effects, and the maintenance of effects, of AET and CBT on functioning and QoL in patients with ALS. The results of this study are expected to generate new evidence for the effect of multidisciplinary care of persons with ALS. TRIAL REGISTRATION: Dutch Trial Register NTR1616.

Using patient-reported symptoms of dyspnea for screening reduced respiratory function in patients with motor neuron diseases.

BACKGROUND: Poor monitoring of respiratory function may lead to late initiation of non-invasive ventilation (NIV) in patients with motor neuron diseases (MND). Monitoring could be improved by remotely assessing hypoventilation symptoms between clinic visits. We aimed to determine which patient-reported hypoventilation symptoms are best for screening reduced respiratory function in patients with MND, and compared them to the respiratory domain of the amyotrophic lateral sclerosis functional rating scale (ALSFRS-R). METHODS: This prospective multi-center study included 100 patients with MND, who were able to perform a supine vital capacity test. Reduced respiratory function was defined as a predicted supine vital capacity ≤ 80%. We developed a 14-item hypoventilation symptom questionnaire (HYSQ) based on guidelines, expert opinion and think-aloud interviews with patients. Symptoms of the HYSQ were related to dyspnea, sleep quality, sleepiness/fatigue and pneumonia. The diagnostic performances of these symptoms and the ALSFRS-R respiratory domain were determined from the receiver operating characteristic (ROC) curves, area under the curve (AUC), sensitivity, specificity, predictive values and accuracy. RESULTS: Dyspnea-related symptoms (dyspnea while eating/talking, while lying flat and during light activity) were combined into the MND Dyspnea Scale (MND-DS). ROC curves showed that the MND-DS had the best diagnostic performance, with the highest AUC = 0.72, sensitivity = 75% and accuracy = 71%. Sleep-quality symptoms, sleepiness/fatigue-related symptoms and the ALSFRS-R respiratory domain showed weak diagnostic performance. CONCLUSION: The diagnostic performance of the MND-DS was better than the respiratory domain of the ALSFRS-R for screening reduced respiratory function in patients with MND, and is, therefore, the preferred method for (remotely) monitoring respiratory function.

Psychological distress and coping styles of caregivers of patients with amyotrophic lateral sclerosis: a longitudinal study.

Objectives: To assess psychological distress levels over time in caregivers of patients in the early stage of amyotrophic lateral sclerosis (ALS) and to investigate the association between caregivers' coping styles and psychological distress over time. Methods: Fifty-four caregivers were followed in a RCT of patients in the early stage of ALS. Questionnaires were administered at baseline, 4, 7, and 10 months. Psychological distress was assessed using the Hospital Anxiety and Depression Scale (HADS) and task-, emotion-, and avoidance-oriented coping styles were identified with the short version of the Coping Inventory for Stressful Situations (CISS-21). Analyses were performed using linear mixed models. Results: Caregivers' psychological distress increased by 0.24 points on the HADS per month (p = 0.01). An emotion-oriented coping style was positively associated with psychological distress in caregivers (b = 0.90, p < 0.01), but did not influence the development of psychological distress over time. The avoidance-oriented coping style and the task-oriented coping style were not significantly related to psychological distress. Conclusion: Feelings of distress increase in ALS caregivers during the course of the disease of the patient. Emotion-oriented coping is related to psychological distress; however, emotional coping and distress might represent overlapping constructs. Focusing on one coping style in the care for ALS caregivers may be too simplistic for the complex situations they face, as it ignores the fact that people may require different coping strategies in different situations.

Aerobic Exercise Therapy in Ambulatory Patients With ALS: A Randomized Controlled Trial.

BACKGROUND: Weakness caused by motor neuron degeneration in amyotrophic lateral sclerosis (ALS) may result in avoidance of physical activity, resulting in deconditioning and reduced health-related quality of life (HRQoL). OBJECTIVE: To study the effectiveness of aerobic exercise therapy (AET) on disease-specific and generic HRQoL in ambulatory patients with ALS. METHODS: We conducted a multicenter, assessor-blinded, randomized controlled trial. Using a biphasic randomization model, ambulatory ALS patients were assigned (1:1) to AET+usual care (UC), or UC. AET consisted of a 16-week aerobic cycling exercise program. Primary outcome measures were the 40-item ALS assessment questionnaire (ALSAQ-40), and the mental component summary (MCS) and physical component summary (PCS) scores of the short-form survey (SF-36), using linear mixed effects models. Per-protocol (PP) analysis was performed for those patients who attended ≥75% of the training sessions; controls were matched (1:1) by propensity score matching. RESULTS: Of 325 screened patients, 57 were randomized: 27 to AET+UC and 30 to UC. No significant mean slope differences between groups were observed for ALSAQ-40 (-1.07; 95% confidence interval [CI] -2.6 to 0.5, P=0.172) nor for SF-36 MCS (0.24; -0.7 to 1.1, P=0.576) or PCS (-0.51; -1.4 to 0.38, P=0.263). There were no adverse events related to the AET. PP-analyses showed significantly less deterioration in ALSAQ-40 (-1.88, -3.8 to 0.0, P=0.046) in AET+UC compared to UC. CONCLUSIONS: AET+UC was not superior to UC alone in preserving HRQoL in ambulatory ALS patient. However, the study was unfortunately underpowered, because only 10 patients completed the protocol. AET+UC may preserve disease-specific HRQoL in slow progressors. CLINICAL TRIAL REGISTRATION NUMBER: Netherlands National Trial Register (NTR): 1616.

The Åstrand-Ryhming Test is not a Feasible Measure in Ambulatory Patients with Amyotrophic Lateral Sclerosis.

BACKGROUND: Ambulatory patients with Amyotrophic Lateral Sclerosis (ALS) show a decreased aerobic capacity which may hamper the ability to perform activities of daily living. A standardized measure, however, for assessing aerobic capacity in patients with ALS during the disease course, is lacking. OBJECTIVE: To examine the feasibility of the Åstrand-Ryhming (ÅR) test protocol longitudinally in ambulatory patients with amyotrophic lateral sclerosis (ALS). METHODS: Seven ambulatory male patients with spinal ALS onset were assessed at baseline and at 4, 7 and 10 months' follow-up. Feasibility of the ÅR test protocol was analysed using percentage of: a) completed ÅR tests; b) achieved steady states; and c) predefined heart rates. RESULTS: Test completion decreased from 7/7 at baseline to 10/21 at follow-up due to ALS-related symptoms as fatigue, muscle weakness and cramps. Steady states and predefined heart rates were achieved in 12/17 and 17/17 of the completed tests, respectively. Overall, the feasibility of the ÅR test protocol declines from 5/7 at baseline to 7/21 at follow-up. CONCLUSIONS: The results suggest that changes in aerobic capacity in ambulatory patients with ALS could not be successfully monitored due to a diminished feasibility of the ÅR test protocol.

Cognitive behavioural therapy and quality of life in psychologically distressed patients with amyotrophic lateral sclerosis and their caregivers: Results of a prematurely stopped randomized controlled trial.

Our objective was to compare the effects of cognitive behavioural therapy (CBT) and usual care (UC) on quality of life (QoL) in psychologically distressed patients with ALS and their caregivers. We conducted a multicentre randomized controlled trial (RCT). In 16 weeks, patient-carer pairs received five to 10 CBT sessions plus usual care (UC) or UC alone. Outcome measures were SF-36 Mental Component Summary (MCS), ALSAQ-40 Emotional Functioning (EF), Hospital Anxiety and Depression Scale (HADS) and Caregiver Strain Index (CSI). Assessments took place at baseline, four, seven and 10 months. The steering committee decided to stop the trial prematurely and analyse the data due to: 1) slow recruitment (15 patients over 42 months); and 2) the low demand for joint patient-carer CBT sessions. Caregivers, however, expressed an unanticipated demand for individual psychological support. Patients' ALSAQ-40-EF and caregivers' SF-36-MCS were significantly better in CBT than UC (p < 0.05). CSI was significantly lower in the CBT than the UC (p < 0.05). In conclusion, CBT might be beneficial to patients and caregivers. The stringent eligibility criteria limited participation rate and consequently the generalizability of results. Future studies should further examine the impact of CBT interventions for patients with ALS and their caregivers.

Selective motor control of the lower extremities in children with cerebral palsy: inter-rater reliability of two tests.

PURPOSE: The purpose of this study was to examine the inter-rater reliability of two tests measuring selective motor control (SMC) of the lower extremities in children with cerebral palsy (CP). METHODS: Two testers independently assessed 21 children (13 boys, eight girls; mean age 6 years 5 months, SD 12 months) with spastic CP (14 unilateral and seven bilateral) using the Boyd and Graham SMC test (with an existing protocol) and the modified Trost SMC test (with a newly developed protocol). Inter-rater reliability was analysed using Cohen's Kappa. RESULTS: For the Boyd and Graham SMC test for ankle dorsiflexion, Kappa was 0.55 (95% CI = 0.36-0.74). For the modified Trost SMC test for ankle dorsiflexion, knee extension, hip abduction and hip flexion, Kappas were 0.65 (0.47-0.84), 0.69 (0.49-0.88), 0.57 (0.37-0.78) and 0.71 (0.51-0.91), respectively. CONCLUSION: The SMC tests showed moderate (Boyd and Graham SMC test) to good (modified Trost SMC test) inter-rater reliability.
