The Effectiveness of Lower Extremity Strength Training on the Physical Performance of Patients With Chronic Schizophrenia With Sarcopenia.

Methods:

The purpose of this study was to investigate the effects of lower extremity muscle training on the functional performance of sarcopenia in patients with chronic schizophrenia . The study will to examine the effectiveness of a 16-week lower extremity muscle training program on the functional performance of of sarcopenia in patients with chronic schizophrenia Sample size calculation. Sample size was calculated using G*Power 3.1.9.2 software, with reference to a randomized controlled study (Nygård et al., 2023) on the integration of plyometric training into the long-term collaborative care of people with psychosis. ANOVA: Repeated measures, between factors, Effect size: 0.5, α = 0.05, Power = 0.8, 2 groups, 3 measurements per group, results showed that at least 24 cases were enrolled in each group. However, in order to increase the statistical validity and to take into account the possibility of dropout or low attendance, the default attrition rate was 25%, with 30 cases in each group. Considering that the ratio of males to females with psychosis is 1.4:1, the sample size of this study is estimated to be 40 cases in each of the experimental and control groups (24 males and 16 females in each group), making a total of 80 subjects.

Data analysis:

In this study, the data were collected and compiled, coded and entered into a computer file, and processed using the SPSS for windows version 22.0 statistical package for statistical analysis, with the significant level set at α=0.05. The data were analyzed and analyzed using the SPSS for windows version 22.0 statistical software.

Steps Based on the screening results, eight chronic wards with a high number of myasthenia gravis chronic psychosis cases were selected and divided into two groups according to gender (24 males and 16 females in each group), which were randomly assigned to the experimental and control groups by drawing lots with an opaque envelope by a non-study project staff member (a nurse practitioner supervisor). After explaining the purpose of the study and the study process to the subjects, and after the subjects had agreed to participate in the study, they were asked to sign the consent form by telephone with their family members (note the date and time of the telephone call for family members' consent).
