“…However, while a small statistically significant increase was seen at followup (P=0.029), the 5.1-meter difference falls well short of the MCID for a PPS population of 22.9 meters (36). The 30sCST test assesses the complex interaction of momentum and stabilisation required to change from the seated to a standing vertical position (37). A repeated sit-to-stand also requires an element of endurance.…”

Background: Post-polio syndrome is characterised by symptoms of fatigue, pain and new-onset neuromuscular weakness, and emerges decades after the initial poliovirus infection. We sought to evaluate the only post-polio syndrome specific self-management programme in the United Kingdom.Methods: This was a retrospective study of patients who had completed a residential self-management programme led by a multi-disciplinary clinical team. Following a confirmed diagnosis of post-polio syndrome by rehabilitation and neurology specialists, patients were offered to participate in the programme. Although group-based, patients also received individually tailored support on physical exercise and fatigue management. Physical effects, physical function, psychosocial well-being measures were assessed at baseline and 6 months follow-up. Knowledge was tested at baseline and immediately following the programme. Statistical comparisons were made using paired t-test and Wilcoxon signed rank test according to the data distribution. Results: Over a period of 17 years, 214 participants (median age 61.3 years old, 63% female) attended 31 programmes. At 6 months the following post-polio syndrome specific symptoms improved significantly: fatigue, as measured by the Multidimensional Assessment of Fatigue scale [37.6 (7.1) vs. 34.2 (9.3), P=0.005]; and pain [15.

“…As the seat-off phase is considered highly relevant for the stable performance of chair rise ( Schenkman et al, 1990 ; Roebroeck et al, 1994 ), it is assumed that earlier seat-off enables a more stable performance during standing up because of the better-coordinated interplay of the upper and lower body ( Geravand et al, 2017 ). However, the earlier seat-off did not affect the total standing up duration in favor of full support over the touch and unassisted conditions, which is interesting as enhanced performance of chair rise abilities is often assessed by a reduced overall movement duration ( Guralnik et al, 1994 ; Sütcü et al, 2019 ).…”

“…These movements are of high relevance for independent living because they are a major prerequisite for upright posture, which is essential for gait initiation and other activities of daily living ( Galli et al, 2008 ; Lee et al, 2015 ; Bobbert et al, 2016 ; Duarte Wisnesky et al, 2020 ). However, standing up and sitting down are among the most affected activities in older individuals ( Sütçü et al, 2019 ), and because of that, they represent the movements in which fall events most frequently occur in frail, older individuals ( Rapp et al, 2012 ). However, there is still a lack of knowledge about the reasons that lead to falls during standing up and especially during sitting down and whether assistive support increases or decreases movement stability.…”

Four-wheeled walkers or rollators are often used to assist older individuals in maintaining an independent life by compensating for muscle weakness and reduced movement stability. However, limited biomechanical studies have been performed to understand how rollator support affects posture and stability, especially when standing up and sitting down. Therefore, this study examined how stability and posture change with varying levels of rollator support and on an unstable floor. The aim was to collect comprehensive baseline data during standing up and sitting down in young participants. In this study, 20 able-bodied, young participants stood up and sat down both 1) unassisted and assisted using a custom-made robot rollator simulator under 2) full support and 3) touch support. Unassisted and assisted performances were analyzed on normal and unstable floors using balance pads with a compliant surface under each foot. Using 3D motion capturing and two ground-embedded force plates, we compared assistive support and floor conditions for movement duration, the relative timing of seat-off, movement stability (center of pressure (COP) path length and sway area), and posture after standing up (lower body sagittal joint angles) using ANOVA analysis. The relative event of seat-off was earliest under full support compared to touch and unassisted conditions under normal but not under unstable floor conditions. The duration of standing up and sitting down did not differ between support conditions on normal or unstable floors. COP path length and sway area during both standing up and sitting down were lowest under full support regardless of both floor conditions. Hip and knee joints were least flexed under full support, with no differences between touch and unassisted in both floor conditions. Hence, full rollator support led to increased movement stability, while not slowing down the movement, during both standing up and sitting down. During standing up, the full support led to an earlier seat-off and a more upright standing posture when reaching a stable stance. These results indicate that rollator support when handles are correctly aligned does not lead to the detrimental movement alterations of increased forward-leaning. Future research aims to verify these findings in older persons with stability and muscle weakness deficiencies.

“…Among children with MMC, the sit-to-stand task is a reliable outcome measure, which has been examined regarding reliability and concurrent validity in children with MMC [ 32 ]. On the other hand, sit-to-stand activity is a complex activity that should be investigated in terms of its electromyographic features [ 33 ].…”

Effect of photobiomodulation combined with physical therapy on functional performance in children with myelomeningocele: A protocol randomized clinical blind study

et al. 2021

View full text Add to dashboard Cite

Introduction Myelomeningocele is a severe type of spina bifida, resulting from improper closure of the neural tube. This condition drastically affects the structures of the spinal cord resulting in deficiencies. The combination of these deficiencies results in an overall decrease in mobility and functional participation amongst this population. Physiotherapy plays an essential role in rehabilitating people with MMC. The current literature shows that resources such as photobiomodulation (PBM) may support the rehabilitation of neurological conditions. The aim of the proposed study is to evaluate the effects of photobiomodulation (PBM) combined with physical therapy on functional performance in children with low lumbosacral myelomeningocele. Materials and methods This is a protocol randomized clinical blind study, that will include 30 individuals of both sexes, aged between 5 to 8 years, diagnosed with low and sacral lumbar myelomeningocele and capable of performing the sit-to-stand task. The participants will be randomly assigned into two treatment groups: PBM + physiotherapeutic exercises and sham PBM + physiotherapeutic exercises. Irradiation will be carried out with light emitting diode (LED) at a wavelength of 850 nm, energy of 25 J per point, 50 seconds per point and a power of 200 mW. The same device will be used in the placebo group but will not emit light. Muscle activity will be assessed using a portable electromyograph (BTS Engineering) and the sit-to-stand task will be performed as a measure of functioning. Electrodes will be positioned on the lateral gastrocnemius, tibialis anterior and rectus femoris muscles. The Pediatric Evaluation of Disability Inventory will be used to assess functional independence. Quality of life will be assessed using the Child Health Questionnaire—Parent Form 50. Changes in participation will be assessed using the Participation and Environment Measure for Children and Youth. The data will be analyzed with the aid of GraphPad PRISM. Discussion The results of this study can contribute to a better understanding of the effectiveness of PBM on functioning and quality of life in children with myelomeningocele. Clinical trial registration ClinicalTrials.gov Identifier: NCT04425330.
