PTs, Physiotherapist; OE, Occupational Experience; Coef., Coefficient; SE, standard error. “p” represents the level of significance, and “MMST” is an abbreviation of “Muscle strength,” which can be divided into 5 levels and Level 0 indicates the worst muscle strength, where the patient cannot move and has no movement of the limbs; level 5 indicates normal muscle strength.
