Objectives: To determine the content validity of cardiopulmonary exercise testing (CPET) for assessing peak oxygen uptake (VO) in neuromuscular diseases (NMD).
Design: Baseline assessment of a randomized controlled trial.
Setting: Academic hospital.
Objective: To determine the physical strain of walking and assess its relationship with daily steps and intensity of daily activity in people with neuromuscular diseases.
Design: Cross-sectional study.
Subjects/patients: Sixty-one adults with neuromuscular diseases.
Background: Home-based aerobic exercise in people with neuromuscular diseases (NMDs) has benefits compared to exercise in the hospital or a rehabilitation center because traveling is often cumbersome due to mobility limitations, and societal costs are lower. Barriers to home-based aerobic exercise include reduced possibilities for monitoring and lack of motivation. To overcome these and other barriers, we developed a mobile health app: Keep on training with ReVi (hereafter referred to as ReVi).

- The study aimed to explore the relationship between heart rate and perceived exertion during maximal exercise tests and home-based aerobic training for individuals with neuromuscular diseases.
- Participants included those with Charcot-Marie-Tooth disease, post-polio syndrome, or other neuromuscular conditions, who engaged in a 4-month aerobic training program monitored through heart rates and perceived exertion ratings.
- Results showed a strong correlation between heart rate and perceived effort during testing, but notable differences in effort perception during training, suggesting potential issues with under- or over-training that healthcare professionals should consider.
Objective: To systematically evaluate the measurement properties of aerobic capacity measures in neuromuscular diseases.
Data Sources: MEDLINE, EMBASE, SportDiscus and Web of Science Conference Proceedings Citation Index - Science were systematically searched from inception until 30 June 2021.
Study Selection And Data Extraction: Screening, data extraction, risk of bias assessment and quality assessment were performed by 2 independent researchers.
Purpose: Early mobilization of critically ill patients improves functional recovery, but is often hampered by tubes, drains, monitoring devices and muscular weakness. A mobile treadmill with bodyweight support facilitates early mobilization and may shorten recovery time to independent ambulation as compared to usual care physiotherapy alone.
Materials And Methods: Single center RCT, comparing daily bodyweight supported treadmill training (BWSTT) with usual care physiotherapy, in patients who had been or were mechanically ventilated (≥48 h) with ≥MRC grade 2 quadriceps muscle strength.
Background: Aerobic exercise aims to improve aerobic capacity.
Objective: To summarize the evidence on the efficacy of aerobic exercise on aerobic capacity in slowly progressive neuromuscular diseases (NMDs).
Methods: We searched the electronic databases MEDLINE, EMBASE, SPORTDiscus and Web of Science Conference Proceedings Index for articles published up to June 17, 2021, selecting randomized controlled trials that included adults with slowly progressive NMDs and compared aerobic exercise to no aerobic exercise.
Objective: Clear guidelines to prescribe aerobic exercise in neuromuscular diseases (NMD) are lacking, which hampers effective application in neuromuscular rehabilitation. This pilot study evaluated the feasibility and preliminary effectiveness of an individualized aerobic exercise program according to a recently developed training guide (B-FIT) to improve physical fitness in individuals with NMD.
Methods: Thirty-one individuals who were ambulatory and had 15 different slowly progressive NMD participated in a 4-month, polarized, home-based, aerobic exercise program.
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.

May 2020
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.

Design: Cross-sectional survey.
Participants: Dutch rehabilitation specialists and physical therapists in specialized centres for slowly progressive neuromuscular diseases and in primary care.
Objective: To explore reasons for the lack of efficacy of a high intensity aerobic exercise program in post-polio syndrome (PPS) on cardiorespiratory fitness by evaluating adherence to the training program and effects on muscle function.
Design: A process evaluation using data from an RCT.
Patients: Forty-four severely fatigued individuals with PPS were randomized to exercise therapy (n = 22) or usual care (n = 22).
Background: People with postpolio syndrome (PPS) commonly experience severe fatigue that persists over time and negatively affects functioning and health-related quality of life (HRQoL).
Objectives: To study the efficacy of exercise therapy (ET) and cognitive behavioral therapy (CBT) on reducing fatigue and improving activities and HRQoL in patients with PPS.
Methods: We conducted a multicenter, single-blinded, randomized controlled trial.
Objective: To assess the reliability of contractile properties of the knee extensor muscles in 23 individuals with post-polio syndrome (PPS) and 18 age-matched healthy individuals.
Methods: Contractile properties of the knee extensors were assessed from repeated electrically evoked contractions on 2 separate days, with the use of a fixed dynamometer. Reliability was determined for fatigue resistance, rate of torque development (MRTD), and early and late relaxation time (RT50 and RT25), using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM, expressed as % of the mean).
Objectives: To determine whether the anaerobic threshold (AT) can be identified in individuals with postpolio syndrome (PPS) using submaximal incremental exercise testing, and to compare current guidelines for intensity prescription in PPS with the AT.
Design: Cohort study.
Setting: Research laboratory.
The present study investigated whether intrinsic fatigability of the muscle fibers is reduced in patients with post-polio syndrome (PPS). This may contribute to the muscle fatigue complaints reported by patients with PPS. For this purpose, we assessed contractile properties and fatigue resistance of the knee extensor muscles using repeated isometric electrically evoked contractions in 38 patients with PPS and 19 age-matched healthy subjects.
