âIt is something that gives us hopeâ: Lived experience among parents to children with cerebral palsy who are non-ambulant of the phenomenon physical activity, with or without the use of a novel dynamic standing device
IntroductionRegular physical activity confers health benefits for all. Parents commonly want their children to be physically active, and want to be physically active themselves, but children with cerebral palsy (CP) who are non-ambulant face challenges, and they need support to be physically active. Dynamic standing in the novel motorized assistive device Innowalk has positive effects in children who are non-ambulantâit gives them a chance to be physically active. The aim of this study was to explore the lived experience of physical activity of parents themselves and for their children with cerebral palsy who are non-ambulant.MethodsA descriptive inductive design with a hermeneutic phenomenological approach was used for the analysis of interviews with 11 parents of children with CP who are non-ambulant who participated in a study of exercise effects of dynamic standing.ResultsThe parents experienced physical activity for their children as being important but difficult, especially for their child, as described in Theme 1: âBeing aware of health benefits while struggling with family time.â The children were perceived as being dependent on other people, the environment, and equipment for participating in physical activity, referring to Theme 2: âBeing dependent.â The opportunity for their children to become physically active on a regular basis through an assistive device gave the parents hope for a better life, which formed Theme 3: âGetting hope in a challenging life situation.âConclusionPhysical activity for children with CP who are non-ambulant is possible through an elaborate network of social relations and environmental conditions. Limiting the degree of dependence and containing the negative consequences of high a degree of dependence are vital in the support of physical activity. Relations, support, and assistive devices that strengthen empowerment and autonomy should be prioritized, and if this works, the experience of physical activity can be positive, giving families hope
Impact of menstrual function on hormonal response to repeated bouts of intense exercise
Background: Strenous exercise stimulates the hypothalamic-pituitary (HP) axis in order to ensure homeostasis and promote anabolism. Furthermore, exercise stimulates a transient increase in the neurotrophin brain-derived neurotrophic factor (BDNF) suggested to mediate the anxiolytic effects of exercise. Athletes with secondary functional hypothalamic amenorrhea (FHA) have been reported to have lower BDNF, and a blunted HP axis response to exercise as athletes with overtraining syndrome. Aim: The aim of the study was to investigate the hormonal and BDNF responses to a two-bout maximal exercise protocol with four hours of recovery in between in FHA and eumenorrheic (EUM) athletes. Methods: Eumenorrheic (n = 16) and FHA (n = 14) endurance athletes were recruited from national teams and competitive clubs. Protocols included gynecological examination; body composition (DXA); 7-day assessment of energy availability; blood sampling pre and post the two exercises tests. Results: There were no differences between groups in hormonal responses to the first exercise bout. After the second exercise bout IGFBP-3 increased more in FHA compared with EUM athletes (2.1 ± 0.5 vs. 0.6 ± 0.6 ÎŒg/L, p = 0.048). There were non-significant trends toward higher increase in IGF-1 (39.3 ± 4.3 vs. 28.0 ± 4.6 ÎŒg/L, p = 0.074), BDNF (96.5 ± 22.9 vs. 34.4 ± 23.5 ÎŒg/L, p = 0.058), GH to cortisol ratio (0.329 ± 0.010 vs. 0.058 ± 0.010, p = 0.082), and decrease in IGF-1 to IGFBP-3 ratio (â2.04 ± 1.2 vs. 0.92 ± 1.22, p = 0.081) in athletes with FHA compared with EUM athletes. Furthermore, there was a non-significant trend toward a higher increase in prolactin to cortisol ratio in EUM athletes compared with athletes with FHA (0.60 ± 0.15 vs. 0.23 ± 0.15, p = 0.071). No differences in the hormonal or BDNF responses between the two exercise bouts as a result of menstrual function were found. Conclusion: No major differences in the hormonal or BDNF responses between the two exercise bouts as a result of menstrual function could be detected
Exercise and Diabetes-Related Cardiovascular Disease: Systematic Review of Published Evidence from Observational Studies and Clinical Trials
Non-ambulatory children with cerebral palsy : effects of four months of static and dynamic standing exercise on passive range of motion and spasticity in the hip
Purpose: The aim of this study was to compare the effects of four months of two types of structured training regimes, static standing (StS) versus dynamic standing (DyS), on passive range of motion (PROM) and spasticity in the hip among non-ambulatory children with cerebral palsy.Method: Twenty non-ambulatory children with cerebral palsy participated in an exercise intervention study with a crossover design. During StS, the Non-ambulatory children with cerebral palsy were encouraged to exercise according to standard care recommendations, including daily supported StS for 30-90 min. During DyS, daily exercise for at least 30 min at a speed between 30 and 50 rpm in an Innowalk (Made for movement, Norway) was recommended. We assessed adaptive effects from the exercise programs through PROM in the hip assessed with a handheld goniometer, and spasticity in the hip assessed with the Modified Ashworth Scale before and after 30 min of StS or DyS. A trained physiotherapist performed the assessments. The exercise test and exercise training were performed in the children's habitual environment. Non-parametric statistics were used and each leg was used as its own control.Result: PROM increased in all directions after 30 min (p < 0.001), and after four months of exercise training (p < 0.001) of DyS. Thirty minutes of DyS lowered the spasticity in the muscles around the hip (p < 0.001) more than 30 min of StS (p < 0.001).Conclusion: Thirty minutes of DyS increased PROM and decreased spasticity among non-ambulatory children with CP. Four months of DyS increased PROM but did not decrease spasticity. These results can help inform individualised standing recommendations
Acute Response to One Bout of Dynamic Standing Exercise on Blood Glucose and Blood Lactate Among Children and Adolescents With Cerebral Palsy Who are Nonambulant
PURPOSE: To investigate the acute exercise effects of dynamic standing exercise on blood glucose and blood lactate among children and adolescents with cerebral palsy who are nonambulant.METHODS: Twenty-four participants with cerebral palsy who are nonambulant performed 30 minutes of dynamic standing exercise using a motorized device enabling assisted passive movements in an upright weight-bearing position. Capillary blood samples were taken from the fingertip for measurement of blood glucose and blood lactate at rest and at the end of exercise.RESULTS: At rest, the participants had hyperlactatemia that was unaffected after exercise, presented as median and interquartile range at rest 1.8 (1.3:2.7) mmol/L, and after exercise 2.0 (1.1:2.5) mmol/L. Children and adolescents with Gross Motor Function Classification System, level V, had higher lactate levels at rest (2.5 [1.8:2.9] vs 1.4 [1.0:2.0]; P = .030) and after exercise (2.3 [2.0:2.6] vs 1.2 [0.9:2.2]; P = .032) compared with children and adolescents with Gross Motor Function Classification System, level IV, respectively. A statistically significant larger decrease in blood lactate levels after exercise was observed in children and adolescents with higher resting blood lactate levels (Ï = .56; P = .004). There were no statistically significant changes in blood glucose.CONCLUSIONS: Forty percentage of the participants had mild hyperlactatemia at rest and participants with the highest blood lactate levels at rest had the greatest decrease in blood lactate levels after one bout of exercise. Children and adolescents who were classified with the highest level of the Gross Motor Function Classification Scale had higher blood lactate levels. More studies are needed on how to prevent chronically high resting levels of lactate with exercise in children with cerebral palsy who are nonambulant
Acute and Long-Term Changes in Blood-Borne Biomarkers in Response to Dynamic Standing in Nonambulant Children With Cerebral Palsy
PURPOSE: To investigate acute and long-term changes in hormonal and inflammatory biomarkers in nonambulant children with cerebral palsy in response to dynamic standing exercise.METHODS: Fourteen children with severe cerebral palsy were recruited. Anthropometrics and body composition measures were obtained. Physical activity levels before the study were assessed using hip-worn accelerometry. All children underwent a 30-minute dynamic standing exercise using the Innowalk standing aid. Respiratory data during exercise were collected using indirect calorimetry. Blood samples were collected before and after exercise. Blood samples were also obtained after two 16-week exercise protocols, in a resting state. Hormonal and inflammatory metabolites were measured from blood serum/plasma, and acute and long-term changes in biomarker levels were assessed using Wilcoxon signed-rank tests.RESULTS: Of the 14 children at baseline, all had slightly/moderately/severely elevated C-reactive protein and cortisol levels. C-reactive protein levels were decreased following a 30-minute bout of dynamic standing (before exercise: 53 mg/L [interquartile range: 40-201]; after exercise: 39 mg/L [interquartile range: 20-107]; P = .04).CONCLUSIONS: We show that several hormonal and inflammatory biomarkers are dysregulated in children with cerebral palsy. Our preliminary results from a small, but deep-phenotyped prospective cohort indicate acute and long-term alterations of several biomarkers in response to exercise
An evaluation of data processing when using the ActiGraph GT3X accelerometer in non-ambulant children and adolescents with cerebral palsy
PURPOSE: To evaluate vertical acceleration, vector magnitude, non-wear time, valid day classifications and valid period classifications, in the data processing phase when using the ActiGraph GT3X accelerometer in non-ambulant children and adolescents with cerebral palsy (CP).MATERIAL AND METHODS: Accelerometer data retrieved from 33 non-ambulant children and adolescents (4-17 years) with CP, were analysed. Comparisons of i) vertical acceleration versus vector magnitude, ii) two different non-wear times, iii) three different settings to classify a day as valid and iv) two different settings to classify a period as valid were made.RESULTS AND CONCLUSIONS: Vector magnitude and a non-wear time of at least 90 consecutive minutes statistically significantly increased minutes recorded per day, especially for sedentary time. There was a statistically significant difference in numbers of valid days depending on time criteria set to determine a valid day, whereas there was no statistically significant difference in valid periods using 3 compared to 4 days. This study suggests using the pre-settings in ActiLife; vector magnitude, non-wear time of 90 consecutive minutes, 500 minutes recorded per day with periods of at least 3 valid days when assessing physical activity objectively by the ActiGraph GT3X accelerometer in non-ambulant children and adolescents with CP.

Parentsâ lived experience of early risk assessment for cerebral palsy in their young child using a mobile application after discharge from hospital in the newborn period
AbstractIntroduction General Movement assessment (GMA) is considered the golden standard for early identification of infants with a high risk of developing cerebral palsy (CP). The aim of this study was to explore parentsâ lived experience of early risk assessment for CP using a mobile application for home video recording after discharge from hospital stay in the newborn period.Methods An inductive qualitative design using a hermeneutical phenomenological approach was chosen, and fourteen parents with children at risk of CP were interviewed at home. The hermeneutical phenomenological approach describes humansâ lived experiences of a specific phenomenon with a possibility of deeper understanding of the expressed statements. The interviews were analyzed using the fundamental lifeworld existential dimensions as guidelines for describing the parentsâ lived experience.Results The overall understanding of the parentsâ experience was âFinding control in an uncontrolled life situation'. During the often-long hospitalizations, the parents struggled with loss of control and difficulty in understanding what was going on. The use of the mobile application followed by a swift result made them feel in control and have a brighter view of the future.Conclusions The findings suggest that the mobile application did not seem to worry the parents. Instead, it provided the parents with a sense of active participation in the care and treatment of their child. The mobile application should be accompanied with clear instructions and guidelines for the parents and details about how and when the result is given
Occupational sedentariness and breast cancer risk
Background: Epidemiological studies have indicated that physical activity reduces the risk of developing breast cancer. More recently, sedentary behavior has been suggested as a risk factor independent of physical activity level. The purpose of the present study was to investigate occupational sedentariness and breast cancer risk in pre- and postmenopausal women. Materials and methods: In a population-based prospective cohort study (n = 29 524), working history was assessed by a questionnaire between 1990 and 1992. Participants were classified as having: (1) sedentary occupations only; (2) mixed occupations or (3) non-sedentary occupations only. The association between occupational sedentariness and breast cancer incidence was analyzed by Cox regression, adjusted for known risk factors and participation in competitive sports. Results: Women with a working history of occupational sedentariness had a significantly increased risk of breast cancer (adjusted HR 1.20; 95% CI 1.05, 1.37) compared with those with mixed or non-sedentary occupations. The association was stronger among women younger than 55 years (adjusted HR 1.54; 95% CI 1.20, 1.96), whereas no association was seen in women 55 years or older. Adjustment for participation in competitive sports did not change the association. Conclusions: We found that occupational sedentariness was associated with increased breast cancer risk, especially in women younger than 55 years. This may be a modifiable risk factor by planning breaks during the working day. Whether this reduces the risk of breast cancer needs to be further studied
Immediate increase in perceived energy after exercise during the course of chemotherapy treatment for breast cancer
Purpose: Exercise during chemotherapy has beneficial long-term effects on women with breast cancer, but shortterm beneficial changes have been less investigated. Though short-term changes may be important as a encouraging factor, this study aimed to investigate immediate changes in self-reported energy, stress, nausea and pain following a single exercise session during chemotherapy. Methods: Forty-six women who were exercising while undergoing adjuvant chemotherapy for breast cancer were included between October 2016 and April 2018. Self-reported energy and stress were assessed before, immediately after and 3 h after exercise sessions by the Stress-Energy Questionnaire. On the same questionnaire nausea and pain were assessed by a Visual Analog Scale. The measurements were completed at four time points during cycles 2 and 5 of the 6-cycle chemotherapy course. Results: Energy level increased immediately after a single exercise session for three out of four periods during the chemotherapy course (p < 0.01), with a larger increase when energy was lower before the session (p < 0.01). Three hours after the exercise session, the energy was about the same level as before the exercise session. Stress decreased immediately after the session during cycle two (p < 0.01) but not cycle five. There were no changes in nausea or pain. Conclusions: Patients undergoing chemotherapy should be informed not only about the long-term advantages of exercise, but also immediate benefits in terms of increased energy. The energy increase both while exercise in the beginning and toward the end of the chemotherapy course, this short-term advantageous consequence may strengthen patients' motivation to exercise. Clinicians should also inform patients that exercise does not seem to worsen nausea and pain
