One LOE II study by Cifu et al. did a multicenter analysis on the
relationship between therapy intensity and rehabilitation outcomes
after traumatic brain injury. Te objective was to identify factors relating
to the intensity of rehabilitation services received and to ascertain the
relation between injury outcomes, demographics, types of therapy, and
the intensity of rehabilitation services provided. There were 491 enrolled
patients with a mean age of ± SD 34.3 ± 15.88 years in a setting where
continuum of care included emergency medical services, intensive and
acute care medical care and inpatient rehabilitation. Te results showed
that age predicted the intensity of both psychologic (P < 0.001) and
total therapy (P < 0.01) services. Acute care length of stay was also a
significant predictor of psychologic/cognitive services (P < 0.01).
Therapy intensity was predictive of motor functioning at discharge (P <
0.001). Findings support the assertions that increased therapy intensity,
particularly physical and psychologic/cognitive therapies, enhances
functional outcomes [7].
