List of metropolitan areas by population. One concept which measures the world's largest cities is that of the metropolitan area, which is based on the concept of a labor market area and is typically defined as an employment core (an area with a high density of available jobs) and the surrounding areas that have strong commuting ties to the core.
Average Costs. In treatment year 1, the average costs per patient diagnosed with PTSD ($8,300), TBI ($11,700), or both ($13,800) were much higher than the average costs for those with neither PTSD nor TBI ($2,400) (see Table 2 and Figure 3 on page 20).
Medical equipment such as a knee brace and crutches can add $500 or more to the total if you are not covered by insurance. Physical therapy at $50 to $75 or more per hour can add $1,000 or more to the cost. Pain medication usually is prescribed during recovery.
