The supply and demand for rehabilitation health workforce in Saudi Arabia.

Background: Adequate supply of rehabilitation health workforce is a prerequisite for enhancing access to rehabilitation care. However, there is a lack of comprehensive data regarding the supply of rehabilitation health workers in Saudi Arabia. Aims: To determine the need for, and supply of, rehabilitation workforce, and investigate the relationship between rehabilitation workforce supply and rehabilitation needs in Saudi Arabia. Methodology: This cross-sectional study measured the ratio of physiotherapists and occupational therapists per 10 000 population. Data were obtained from the Ministry of Health, family health survey and census data of the General Authority for Statistics and published literature. To assess the need for rehabilitation services, we computed a composite disability index based on 3 variables: count of individuals with physical disabilities, those with chronic diseases, and those aged > 65 years. Determinants of the supply potential were population size, rural population percentage, and physician supply. Data were analysed using descriptive statistics and simple linear regression. Results: The ratios of physiotherapists and occupational therapists working at the Ministry of Health facilities were 0.69 and 0.03 per 10 000 population, respectively. Overall rehabilitation health workforce ratio was 0.73 per 10 000. Supply varied across regions, from 0.4 for Riyadh to 2.5 for Al Jouf. Nine regions exceeded the overall ratio. Rehabilitation need index ranged from 0.144 in Najran to 0.212 in Aseer. No significant associations were found between rehabilitation workforce supply on one hand, and need and other potential determinants on the other hand. Conclusion: The rehabilitation workforce supply in Saudi Arabia surpassed the regional and global averages, but was lower than the average for high-income countries. Workforce distribution varied by region across the country and was not related to need. It is important to consider the need for rehabilitation services and context-specific factors when determining the optimal size and distribution of the rehabilitation health workforce in Saudi Arabia.

The reliability and criterion validity of 2D video assessment of single leg squat and hop landing.

The objective was to assess the intra-tester, within and between day reliability of measurement of hip adduction (HADD) and frontal plane projection angles (FPPA) during single leg squat (SLS) and single leg landing (SLL) using 2D video and the validity of these measurements against those found during 3D motion capture. 15 healthy subjects had their SLS and SLL assessed using 3D motion capture and video analysis. Inter-tester reliability for both SLS and SLL when measuring FPPA and HADD show excellent correlations (ICC2,1 0.97-0.99). Within and between day assessment of SLS and SLL showed good to excellent correlations for both variables (ICC3,1 0.72-91). 2D FPPA measures were found to have good correlation with knee abduction angle in 3-D (r=0.79, p=0.008) during SLS, and also to knee abduction moment (r=0.65, p=0.009). 2D HADD showed very good correlation with 3D HADD during SLS (r=0.81, p=0.001), and a good correlation during SLL (r=0.62, p=0.013). All other associations were weak (r<0.4). This study suggests that 2D video kinematics have a reasonable association to what is being measured with 3D motion capture.
