Brief summary
This non-randomized clinical study aims to evaluate whether a multicomponent physical exercise program with integrated postural hygiene can improve functional capacity, postural risk, musculoskeletal symptoms, health-related quality of life, and body composition in adult and older women. Eighty participants are allocated to three groups: an experimental group performing exercise with integrated postural hygiene, a reference group with previous postural hygiene training performing the same intervention, and a control group performing the same exercise program without the postural hygiene component. Participants are assessed before, during, and after the intervention, as well as at follow-up. The broader research project also includes a separate cross-sectional observational component designed to describe postural habits, musculoskeletal symptoms, and functional health-related variables in women enrolled in a community-based Maintenance Gymnastics program.
Detailed description
The primary component is a non-randomized interventional study with parallel assignment designed to evaluate the effects of a multicomponent physical exercise program integrating postural hygiene strategies. The study is being registered after participant enrollment had started due to an administrative oversight. Data collection is ongoing and has not yet been completed. The intervention protocol, assessment schedule, and outcome measures were defined before completion of data collection and have not been modified based on study findings. The interventional component includes 80 adult and older women allocated to three groups. The experimental group performs a multicomponent physical exercise program with integrated postural hygiene. The reference group consists of participants who had previously received postural hygiene training and performs the same intervention as the experimental group. The control group performs the same multicomponent physical exercise program without the specific postural hygiene component. The intervention includes exercises targeting strength, balance, mobility, and postural control. Postural hygiene strategies are integrated throughout exercise practice and are intended to facilitate the transfer of healthy postural behaviors to activities of daily living. These strategies aim to improve postural awareness, movement control, and safer postural habits during functional tasks. Participants are assessed at four time points: baseline, mid-intervention, post-intervention, and follow-up. Outcomes include functional capacity, postural risk, musculoskeletal symptoms, health-related quality of life, and body composition. Semi-structured interviews are also conducted to explore perceived changes, program acceptability, postural awareness, and the application of postural hygiene strategies in daily life. The study is non-pharmacological, non-surgical, and non-invasive. It does not involve drug administration, surgical procedures, invasive techniques, or investigational medical devices. The intervention is delivered by trained instructors following a standardized protocol to ensure consistency across groups. In addition to the interventional component, the broader project includes a separate cross-sectional observational epidemiological study conducted in a larger sample of women enrolled in the Maintenance Gymnastics program. This component is based exclusively on questionnaire data and aims to describe postural habits, musculoskeletal symptoms, body perception, and variables related to functional health in the target population. It does not include any intervention, group allocation, or follow-up assessments.
Interventions
BEHAVIORALMulticomponent physical exercise with integrated postural hygiene
Structured multicomponent physical exercise program including strength, balance, mobility, and postural control exercises, with integrated postural hygiene strategies during exercise execution and activities of daily living. Sessions will be conducted in the usual practice context, following a previously established common protocol and with implementation control by program instructors. This intervention will be assigned to the two arms with integrated postural hygiene.
BEHAVIORALMulticomponent physical exercise without postural control
Structured multicomponent physical exercise program including strength, balance, and mobility exercises, delivered without the specific postural control component. Sessions will be conducted in the usual practice context, following a previously established common protocol and with implementation control by program instructors. This intervention will be assigned to the active comparator arm without postural control.

SINGLE (Subject)
Masking description
Participants were blinded to group allocation and comparison. The study was conducted within a broad Maintenance Gymnastics program. Participants from the different groups had no structured contact with one another, were not aware of the existence or specific characteristics of the other study groups, and could not compare the contents applied in each group. Therefore, they were unaware of the main comparative hypothesis and the relative allocation of the groups.
Intervention model description
This a non-randomized interventional study with three parallel groups: experimental group, reference group, and control group. The experimental group will perform multicomponent physical exercise with integrated postural hygiene. The reference group will consist of participants with previous knowledge of postural hygiene and will perform the same intervention as the experimental group. The control group will perform the same multicomponent physical exercise program, but without the specific postural hygiene component.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Functional Mobility Assessed Using the Timed Up and Go | Baseline, mid-intervention (4.5 months), post-intervention (9 months), and 6 months after completion of the intervention (15 months from baseline) | The Timed Up and Go (TUG) test assesses functional mobility by measuring the time required for a participant to stand up from a chair, walk 3 meters, turn around, walk back, and sit down. Lower values indicate better functional mobility and balance. Unit of Measure: seconds |
| Change in Physical Performance Assessed Using the Short Physical Performance Battery | Baseline, mid-intervention (4.5 months), post-intervention (9 months), and 6 months after completion of the intervention (15 months from baseline) | The Short Physical Performance Battery (SPPB) assesses physical performance using three standardized components: standing balance, usual gait speed, and the chair stand test. The balance assessment includes side-by-side, semi-tandem, and tandem standing positions. Gait speed is evaluated over a short walking distance, and lower-extremity functional strength is assessed using the repeated chair stand test. Each component is scored from 0 to 4 points, and the total score ranges from 0 to 12 points, with higher scores indicating better physical performance. Unit of Measure: Points |
| Change in Postural Risk Assessed Using the Rapid Entire Body Assessment | Baseline, mid-intervention (4.5 months), post-intervention (9 months), and 6 months after completion of the intervention (15 months from baseline) | The Rapid Entire Body Assessment (REBA) is an observational ergonomic assessment tool used to evaluate postural risk during functional tasks and movements. The assessment considers body posture, force/load handling, coupling, and activity level by examining the position of the neck, trunk, legs, upper arms, lower arms, and wrists. Total scores range from 1 to 15 points, with higher scores indicating greater postural and musculoskeletal risk and lower scores indicating lower postural risk. Unit of Measure: Points |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Musculoskeletal Symptoms Assessed Using the Nordic Musculoskeletal Questionnaire | Baseline, mid-intervention (4.5 months), post-intervention (9 months), and 6 months after completion of the intervention (15 months from baseline) | The Nordic Musculoskeletal Questionnaire (NMQ) is a standardized questionnaire used to assess the presence and anatomical distribution of musculoskeletal symptoms across body regions, including the neck, shoulders, upper back, lower back, elbows, wrists/hands, hips/thighs, knees, and ankles/feet. The questionnaire records the presence or absence of pain, discomfort, or musculoskeletal symptoms during specified time periods. Results are reported separately for each body region, with a lower prevalence of symptoms indicating a better outcome. Unit of Measure: Presence or absence of musculoskeletal symptoms by body region. |
| Change in Health-Related Quality of Life Assessed Using the SF-36 Questionnaire | Baseline, mid-intervention (4.5 months), post-intervention (9 months), and 6 months after completion of the intervention (15 months from baseline) | The 36-Item Short Form Health Survey (SF-36) is a standardized questionnaire used to assess health-related quality of life across eight domains: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. Scores are transformed to a scale ranging from 0 to 100 points, with higher scores indicating better perceived health status and quality of life. Unit of Measure: Points |
| Change in Body Composition Assessed Using the TANITA BC-401 Monitor | Baseline, mid-intervention (4.5 months), post-intervention (9 months), and 6 months after completion of the intervention (15 months from baseline) | Body composition will be assessed using the TANITA BC-401 body composition monitor. The following parameters will be recorded: body weight (kg), body fat percentage (%), muscle mass (kg), visceral fat (rating), total body water (%), bone mass (kg), and body mass index (kg/m²). Higher muscle mass and total body water values, together with lower body fat percentage, visceral fat and BMI values, indicate improved body composition outcomes following the intervention. |
| Postural Awareness Scale | Baseline | The Postural Awareness Scale (PAS) is a self-report questionnaire designed to assess an individual's awareness of body posture, body alignment, and postural sensations during daily activities. The scale evaluates conscious perception of body position, muscular tension, and postural adjustments. Higher scores indicate greater postural awareness and improved perception of body posture and movement. Unit of Measure: points |
| Back Pain and Body Posture Questionnaire | Baseline | The Back Pain and Body Posture Evaluation Instrument for Adults (BackPEI-A) is a self-administered questionnaire designed to assess back pain prevalence, postural habits, ergonomic behaviors, and lifestyle-related factors associated with spinal health in adults. The questionnaire includes items related to pain frequency and intensity, sitting posture, sleeping posture, backpack or load carrying habits, physical activity, and daily postural behaviors. Higher frequencies of inappropriate postural habits and back pain symptoms indicate poorer spinal health and postural behavior outcomes. Unit of Measure: categorical responses and frequency scores |
