Table 2 Spearman’s correlation coefficients (r) between the stiffness of the bilateral masseter muscle and masticatory performance.
Item | Masticatory performance of affected side | Masticatory performance of unaffected side | ||
---|---|---|---|---|
r | P | r | P | |
The stiffness of masseter muscle on the affected side | −0.65 | 0.002 | −0.62 | 0.004 |
The stiffness of the masseter muscle on the unaffected side | −0.35 | 0.14 | −0.35 | 0.13 |
