Relation between Negative Symptoms and Core Stability as an Indicator of Functional Exercise Capacity in Schizophrenia
Bibliographic record
Abstract
INTRODUCTION: The core refers to the lumbo-pelvic complex located at the center of gravity of the body.Core stability has a crucial role in sudden balance change and body movements(Zemkova et al. Front. Physiol 2022; 13).The more stabilized core muscles indicate better movements and body balance.Therefore, core stability is related with exercise performance, falling risk and falling fear.However, patients with schizophrenia have lower motivation and capability to exercise compared to normal population that may result decrease in core stability. OBJECTIVES: The aim of this study is to determine the relation between core stability,functional exercise capacity and negative symptoms including especially anhedonia, motivation, psychosocial functioning in schizophrenia patients.As our knowledge,this is the first study to detect the core stability in schizophrenia. METHODS: Participants of the study were recruited from the Community Mental Health Service of Çigli Education and Research Hospital. Twenty-six individuals diagnosed as schizophrenia according to DSM-V criteria were included into the study.Symptom severity was evaluated with Positive and Negative Syndrome Scale(PANSS), psychosocial functioning was assessed with Personal and Social Performance Scale(PSP),depression was assessed using Calgary Depression Scale for Schizophrenia(CDSS),avoidance motivation assessed with Behavioral Inhibition System and Behavioral Activation System (BIS/BAS),social and physical pleasure were measured via Revised Social Anhedonia Scale (RSAS) and Revised Physical Anhedonia Scale Functional (RPAS) exercise capacity was assessed by 6-minute walking test(6MWT) and core stability was assessed using Mcgill Core Endurance Tests(MCET).Patients who exercise regularly, having metabolic diseases or comorbid psychiatric disorder were excluded from the study.The data was analyzed by IBM SPSS 24 with Pearson correlation test. RESULTS: MCET scores were found to be moderately correlated to PSP scores (r=.45,p=.025) and BIS sensitivity was moderately correlated to psychosocial functioning (r=-.42,p=.035).Six-MWT scores were negatively correlated with BIS (r=-.51, p=.019),CSDC (r=-.47, p=.035) and PANSS negative subscale (r=-.42, p=.042). CONCLUSIONS: In this study core stability was found to be related to psychosocial functioning.Also,patients having negative symptoms and depression showed lower functional exercise capacity.Lower scores in social functioning and higher behavioral inhibition sensitivity may be related to psychosocial dysfunctioning and negative symptoms of schizophrenia.However, appropriate core stability training and physical exercise may help individuals with schizophrenia to improve these skills.This may lead patients to exercise,have better social performance,self-care and lower avoidance behavior.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
