Ethical approval was obtained from the Ministry of Health, General Directorate of Health Affairs, Al-Qassim Region, Saudi Arabia (Approval No.: 607/45/14477). All procedures were conducted in accordance with institutional ethical standards. Informed consent was obtained from all participants prior to data collection. Participation was voluntary, and responses were kept confidential. The research tools used in the protocol are listed in the Table of Materials.
1. Study design and participants
The study utilized a cross-sectional design conducted from May to September 2024. Data were collected using either a clinic-based, interviewer-administered structured interview or an online self-administered survey platform. In both modes, participants completed identical questionnaire items in the same order. To minimize duplicate entries, participants were asked whether they had previously completed the survey; online responses were restricted to one submission per device or account where possible, and clinic participants were not provided access to the online survey after enrollment. Convenience sampling was used to recruit participants through social media and outpatient clinics. This study was designed as a pilot study; therefore, a formal a priori power calculation was not performed. A target sample size of approximately 50 participants was set to evaluate study feasibility and generate preliminary estimates relevant to the study aims.
Inclusion criteria were diagnosis of SCI, age ≥18 years, and current residence in Saudi Arabia. Individuals with concurrent brain injuries or severe polytrauma, as well as those with other disabling neurological or medical conditions (e.g., stroke, Parkinson’s disease, or Alzheimer’s disease), were excluded.
2. Data collection form
Demographic and lesion-related data were collected. Participants also completed measures assessing knowledge and awareness of physical activity guidelines, physical activity level, and perceived barriers to and facilitators of physical activity participation.
3. Demographic and lesion characteristics
Demographic variables included age, sex, smoking status, marital status, employment status, education level, height, and weight. Lesion-related variables included time since injury, injury etiology (traumatic or non-traumatic), injury completeness (complete or incomplete), neurological presentation (paraplegia or tetraplegia), and use of mobility aids (manual wheelchair, powered wheelchair, crutches, walker, orthotic braces, or none). All variables were collected via self-report during the survey or interview. Participants were permitted to select more than one mobility aid.
4. Knowledge and awareness of physical activity guideline
Knowledge and awareness of physical activity recommendations were assessed using a brief set of questions. Participants were first asked whether they had ever read or heard about physical activity recommendations (yes/no). All participants were then asked to report the recommended weekly amount of aerobic physical activity and the recommended frequency of strength-training exercise per week for adults living with disabilities. Responses were scored as correct or incorrect using operational criteria derived from World Health Organization recommendations, defined as at least 150 minutes per week of moderate-to-vigorous intensity aerobic activity and strength training involving major muscle groups at least twice per week12.
5. Physical activity scale for individuals with physical disabilities
The Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) was developed to assess physical activity levels in individuals with disabilities for epidemiologic studies on health and function16. This scale adapts the earlier validated Physical Activity Scale for the Elderly (PASE)16 through qualitative interviews with individuals with disabilities and rehabilitation professionals, ensuring its relevance and comprehensibility. The final version of PASIPD includes 13 items categorized into leisure (6), household (6), and occupational (1) activities, with respondents indicating the frequency of participation and the average daily duration. Scoring involves multiplying the average hours for each activity by associated metabolic equivalent (MET) values, yielding a maximum possible score of 199.5 MET-hr/day. Total scores are expressed in metabolic equivalent task hours per day (MET-hr/day). For descriptive purposes, PASIPD items were summarized into four scales and measured in MET-hr/day. These scales include (1) home repair, lawn, and garden activities; (2) housework; (3) sport and recreational activities; and (4) occupational and transportation activities. The PASIPD scale has been translated into Arabic and validated17. The PASIPD instrument and scoring instructions are provided in Supplementary File 1.
6. Perceived barriers and facilitators of physical activity
Perceived barriers to and facilitators of physical activity were assessed using a checklist of 12 items for each category. Participants were asked to select all items that applied to them. Items were adapted from prior studies, including 10 items reported by Matheri and Frantz (2009)18 and two additional items identified from subsequent studies19,20. The checklist was administered in Arabic, translated by a bilingual researcher, and reviewed by two rehabilitation clinicians for clarity and content validity.
7. Data analysis
Descriptive statistics were used to summarize knowledge and awareness, physical activity levels, and perceived barriers and facilitators among participants. Data were analyzed using SPSS Statistics (version 29). Only participants who completed the survey or interview were included in the analysis. Results are reported as mean ± standard deviation (SD) for continuous variables and counts (n) and percentages (%) for categorical variables. Figures were generated using a spreadsheet program.
