PURPOSE: The objective of this study was to compare the effects of an in-clinic cervicovestibular rehabilitation program (education, home exercises, manual techniques, sub-symptom threshold aerobic exercise (STAE) program) to a similar program (education, home-exercises, STAE program), but without manual techniques, provided in a telerehabilitation format in adults with persisting post-concussion symptoms (PCS). MATERIALS AND METHODS DESIGN: In this parallel-group non-randomized clinical trial, 41 adults with persisting PCS were allocated to the in-clinic (n = 30) or telerehabilitation (n = 11) program. The outcome measures, which included the Post-Concussion Symptom Scale (PCSS; primary outcome), Numerical Pain Rating Scale (NPRS) for neck pain and headache and three disability questionnaires, were collected at baseline, weeks 6, 12, and 26. Non-parametric analysis for longitudinal data (NparLD) was used. RESULTS: For the PCSS, there was a group-by-time interaction (p = 0.05) with significant between-group differences at week 6, 12, and 26 (p < 0.05) for the in-clinic group. There were also group-by-time interactions for NPRS neck pain and headache (p < 0.05) for the in-clinic group. CONCLUSION: The study suggests that a telehealth format failed to reach the efficiency of an in-clinic rehabilitation program in terms of symptoms reduction and functional improvement. These results must be interpreted with caution given the limited number of participants. ClinicalTrials.gov Identifier: NCT03677661.
