âInMotionââMixed physical exercise program with creative movement as an intervention for adults with schizophrenia: study protocol for a randomized controlled trial
BackgroundSchizophrenia is among the worldâs top 10 causes of long-term disability with symptoms that lead to major problems in social and occupational functioning, and in self-care. Therefore, it is important to investigate the efficacy of complementary treatment options for conventionally used antipsychotic medication, such as physical training, and psychosocial interventions.ObjectiveTo combine aerobic and strength training with cognitive, emotional and social stimulation in one intervention for people with schizophrenia and test the feasibility and effects of this intervention.MethodsThe study is a mixed-method randomized controlled trial to evaluate the effects of a 12-week intervention for adults with schizophrenia. The treatment group (30 participants) will receive the intervention in addition to standard care and the control group (30 participants) only standard care. The intervention consists of 24 biweekly sessions with a duration of 60 min. The pre-test (weeks from 4 to 2 prior to the intervention) and post-test (week 12) include clinical measure (PANSS), quality of life, social performance, movement quantity, brain function and eye tracking measures. In addition, a treatment subgroup of 12â15 participants and their family member or other next of kin will complete a qualitative interview as a part of their post-test. Two follow-up tests, including clinical, quality of life, brain function and eye tracking will be made at 6 and 12 months from the completion of the intervention to both study groups. The primary outcome is change in negative symptoms. Secondary outcome measures include general and positive symptoms, quality of life, social performance, movement quantity, brain function and eye tracking. Explorative outcome includes patient and family member or other next of kin interview.ResultsPilot data was collected by June 2023 and the main data collection will begin in September 2023. The final follow-up is anticipated to be completed by 2026.ConclusionThe InMotion study will provide new knowledge on the feasibility, efficacy, and experiences of a novel intervention for adults with schizophrenia. The hypothesis is that regular participation in the intervention will reduce clinical symptoms, normalize physiological measures such as brain activation, and contribute to new active habits for the participants.Trial registrationClinicalTrials.gov, identifier NCT05673941
On the role of transversus abdominis in trunk motor control
All trunk muscles are important contributors to spine stability. However, the deepest abdominal muscle, transversus abdominis (TrA), with its characteristically horizontal fibre orientation seems to serve a unique function in trunk motor control. The main mechanical role of TrA is believed to be to contribute to vertebral alignment during imposed moments on the trunk, executed mainly via either regulating the pressure level within the abdominal cavity and/or transmit forces to the spine via the thoracolumbar fascia. However, the complete function of TrA and what factors affect its activation are still not fully understood. The purpose of the present thesis was to investigate the role of TrA in trunk motor control, specifically in relation to the presence or absence of postural demand on the trunk. The timing and magnitude of TrA activation were investigated, in relation to other trunk muscles, with intramuscular fine-wire electrodes in different loading situations and body positions with varying postural demand. In a side-lying position, with no postural demand of keeping the trunk upright, the activation of TrA was delayed relative the superficial abdominal muscles compared to previous experiments performed in a standing position. The timing and magnitude of activation of TrA did not depend upon the direction of perturbation. In the standing position, different static arm positions revealed that the activation of TrA co-varied with variations in the degree of postural demand on the trunk and also the imposed moments, regardless of moment direction. Finally, a study on rapid arm flexion movements confirmed that TrA is part of the pre-programmed anticipatory response in advance of known perturbations. The activation magnitude of TrA was the same regardless if the arm movement induced flexion or extension moments on the trunk. In conclusion, the activation of TrA is associated with the upright postural demand on the trunk and with balancing imposed moments acting on the spine, regardless their direction. The findings are in support of the beliefs that TrA act as a general, direction non specific, stabilizer of the lumbar spine

Physiotherapists' and midwives' views of increased inter recti abdominis distance and its management in women after childbirth
Background: Physiotherapists and midwives in primary healthcare often encounter women with an increased separation between the two rectus abdominis muscle bellies after pregnancy, a so-called increased inter recti distance (IRD). There are few studies on the contribution of increased IRD to the explanation of post-partum health complaints, and very little guidance in the literature for health professionals on the management of increased IRD. The aim of this study was to describe how physiotherapists and midwives in primary healthcare perceive the phenomenon of increased IRD and its management in women after childbirth. Methods: A purposeful sampling approach was used to select physiotherapists and midwives working in primary healthcare in three large county council healthcare organisations in Sweden having experience of encountering women with increased IRD after pregnancy. Sixteen physiotherapists and midwives participated in focus group discussions. Four focus groups with four participants in each were undertaken. A semi-structured topic guide was used to explore responses to the research questions and the discussions were analysed using qualitative content analysis. Results: We identified an overarching theme: Ambivalence towards the phenomenon increased IRD and frustration over insufficient professional knowledge. The theme included three categories: Uncertainty concerning the significance of increased IRD as a causal factor for functional problems; perceived insufficient professional knowledge base for the management of increased IRD; and lack of inter-professional collaboration and teamwork in the management of patients with increased IRD. Due to sparse and somewhat contradictory research findings and absence of clinical guidelines, the health professionals lacked basic preconditions for applying an evidence-based practice concerning increased IRD. They obtained their information about increased IRD from the media and fitness coaches, and hence were somewhat unsure about what to believe regarding the phenomenon. Conclusions: There was no consensus among the health professionals on how to best approach increased IRD in the clinical setting. Our findings stress the importance of more research to increase the professional knowledge base among physiotherapists and midwives. The findings highlight the urgent need for policies and clinical guidelines advising health professionals in the management of increased IRD and for facilitating inter-professional collaboration and teamwork
Predictors of Disability Attributed to Symptoms of Increased Interrecti Distance in Women after Childbirth : An Observational Study
Objective The purpose of this study was to investigate how various physical and psychological factors are linked to disability attributed to symptoms from increased interrecti distance (IRD) in women after childbirth. Methods In this cross-sectional observational study, 141 women with an IRD of at least 2 finger-widths and whose youngest child was between the ages of 1 and 8Â years participated. A multiple linear regression model was performed, with disability as the outcome variable and fear-avoidance beliefs, emotional distress, body mass index, lumbopelvic pain, IRD, and physical activity level as predictor variables. Results The regression model accounted for 60% (R2Â =Â 0.604, adjusted R2Â =Â 0.586) of the variance in disability (F6,132Â =Â 33.5). The 2 strongest predictors were lumbopelvic pain, with a regression coefficient of 1.4 (95% CIÂ =Â 1.017 to 1.877), and fear avoidance, with a regression coefficient of 0.421 (95% CIÂ =Â 0.287 to 0.555). The actual IRD, with a regression coefficient of â0.133 (95% CIÂ =Â â1.154 to 0.888), did not contribute significantly to the variation in disability. Conclusion Disability attributed to symptoms from an increased IRD is explained primarily by the level of lumbopelvic pain but also by the degree of fear-avoidance beliefs and emotional distress. Impact This study highlights pain intensity and psychological factors as crucial factors for understanding disability attributed to increased IRD
Women's experiences of living with increased inter-recti distance after childbirth : an interview study
Background Although an increased inter-recti distance, also known as diastasis recti, is common after pregnancy, evidence-based knowledge about the condition is relatively limited. In particular, little is known about the consequences as perceived by the women. The objective of the present study was to describe how postpartum women with increased inter-recti distance experience the condition as well as the contacts they have had with healthcare providers regarding their symptoms. Methods A purposeful sampling approach was used to recruit 19 participants from an existing study cohort of 144 women. All participants had an inter-recti distance of at least two finger widths and at least one child, with the youngest child between the ages of 1 and 6Â years. Individual interviews based on a semi-structured interview guide were performed and subsequently analysed using qualitative content analysis. Results Four categories emerged from the interviews: the bodyâs function and ability has changed; the body does not look like it used to; uncomprehending attitudes and treatment in their surroundings; and trying to acquire an understanding of and strategies to cope with the diastasis. The findings reveal that women with increased inter-recti distance might experience fear of movement and engage in avoidance behaviour. In combination with feelings of physical instability in the midsection of their bodies and body dissatisfaction, many of the women restrict their everyday lives and physical activities. Conclusions The findings indicate that increased inter-recti distance is a complex phenomenon that affects the women in a multitude of ways, highlighting the importance of considering the condition for each individual in her own context from a biopsychosocial perspective

Directional preference of activation of abdominal and paraspinal muscles during position-control tasks in sitting
Controversy exists in the literature regarding antagonist activity of trunk muscles during different types of trunk loading, and the direction-specificity of activation of trunk muscles, particularly the deeper trunk muscles. This study aimed to systematically compare activation of a range of trunk muscles between directions of statically applied loads, and to consider the impact of breathing in this activation. In a semi-seated position, 13 healthy male participants resisted moderate inertial loads applied to the trunk in eight different directions. Intramuscular electromyography was recorded from eight abdominal and back muscles on the right side during 1s prior to peak inspiration/expiration. All muscles demonstrated a directional preference of activation. No muscle displayed antagonistic activation during loading conditions of an intensity that exceded that recorded in upright sitting without a load. During these moderate intensity sustained efforts, trunk muscle activation varied little between respiratory phases. Antagonistic muscle activation of amplitude equivalent to the activation recorded in upright sitting without load is sufficient to maintain control of the spine during predictable and sustained low load tasks
