### Intra-Session Reliability  
Intra-session reliability is presented in Table 4. The pre-PHV group exhibited a moderate reliability score in the half-CSRS (ICC = 0.65) and a high reliability score in the CSRS and both outcomes to the left (ICC from 0.80 to 0.85). The mid-PHV group presented a high reliability score (ICC from 0.85 to 0.93; CV from 1.18 to 2.45). The post-PHV group demonstrated moderate reliability scores for the half-CS to right and left sides (ICC = 0.73; 0.64, respectively) and a high reliability score in the CS performance for both sides.
