An Exploration of the Impact of Initial Timing of Physical Therapy on Safety and Outcomes After Concussion in Adolescents.

There was no control group, so symptom improvement cannot be separated from natural recovery or other treatments. The study reviewed medical records after care had occurred, so full completion of care, adherence, and exact PT protocols were not reliably known. Physicians chose referral timing, and the late group had more previous concussions than the early and middle groups, so groups may not have been comparable. Unplanned healthcare visits could have been missed unless they were documented in the records. All therapists had concussion-specific training, so the approach may not transfer to clinicians without that training. The sample may have been too small to detect meaningful differences between timing groups. The PT program used several components tailored to impairments, so the contribution of any single component cannot be separated.

The authors report no conflicts of interest. The article is listed as supported by extramural NIH funding.

Do not read this as proof that starting physical therapy earlier after concussion improves symptoms faster. The timing groups did not differ in symptom score change, there was no untreated comparison group, and the PT program combined several components, so recovery cannot be separated from natural healing, other care, or any single PT technique.
