Final answer:
The most representative immediate outcome of performing a twice-daily tendon gliding exercise program is enhanced range of motion.
Step-by-step explanation:
The most representative immediate outcome of performing a twice-daily tendon gliding exercise program is enhanced range of motion. Tendon gliding exercises involve moving the tendons and muscles in a specific way to increase flexibility and reduce adhesions. These exercises help to break up scar tissue, improve the sliding of the tendons, and increase the overall range of motion in the affected joint.
