Follow-up visits after a concussion in the pediatric population: An integrative review.

BACKGROUND: Concussions are a significant health issue for children and youth. After a concussion diagnosis, follow-up visits with a health care provider are important for reassessment, continued management, and further education. OBJECTIVE: This review aimed to synthesize and analyse the current state of the literature on follow-up visits of children with a concussive injury and examine the factors associated with follow-up visits. METHODS: An integrative review was conducted based on Whittemore and Knafl's framework. Databases searched included PubMed, MEDLINE, CINAHL, PsycINFO, and Google Scholar. RESULTS: Twenty-four articles were reviewed. We identified follow-up visit rates, timing to a first follow-up visit, and factors associated with follow-up visits as common themes. Follow-up visit rates ranged widely, from 13.2 to 99.5%, but time to the first follow-up visit was only reported in eight studies. Three types of factors were associated with attending a follow-up visit: injury-related factors, individual factors, and health service factors. CONCLUSION: Concussed children and youth have varying rates of follow-up care after an initial concussion diagnosis, with little known about the timing of this visit. Diverse factors are associated with the first follow-up visit. Further research on follow-up visits after a concussion in this population is warranted.

Effects of intermittent exposure to hyperbaric oxygen for the treatment of an acute soft tissue injury.

OBJECTIVE: To assess the hypothesis that subjects exposed to intermittent hyperbaric oxygen treatments would recover from signs and symptoms indicative of delayed-onset muscle soreness faster than subjects exposed to normoxic air. DESIGN: Randomized, double-blinded study with a 4-day treatment protocol. SETTING: University-based sports medicine clinic. PARTICIPANTS: Sixteen sedentary female university students. INTERVENTIONS: All subjects performed 300 maximal voluntary eccentric contractions (30 sets of 10 repetitions per minute) of their nondominant leg (110 to 35 degrees of knee flexion) at a slow speed (30 degrees per second) on a dynamometer to elicit muscle damage and injury. Hyperbaric oxygen treatments consisted of 100% oxygen for 60 minutes at 2.0 atmospheres absolute (ATA), while the control group received 21% oxygen at 1.2 ATA for the same amount of time. Both groups received treatment immediately after the induction of delayed-onset muscle soreness and each day thereafter for a period of 4 days (day 1 postexercise through day 4 postexercise). MAIN OUTCOME MEASURES: Dependent variables (perceived muscle soreness, isokinetic strength, quadriceps circumference, creatine kinase, and malondialdehyde) were assessed at baseline (preexercise, day 0), 4 hours postexercise (day 1), 24 hours postexercise (day 2), 48 hours postexercise (day 3), and 72 hours postexercise (day 4). Magnetic resonance images (T2 relaxation time/short tip inversion recovery) were assessed at baseline (day 0), 24 hours postexercise (day 3), and 72 hours postexercise (day 5). RESULTS: Repeated-measures analysis of variance was performed on all of the dependent variables to assess differences between treatment and control groups. Analyses revealed no significant differences between groups for treatment effects for any of the dependent variables (pain, strength, quadriceps circumference, creatine kinase, malondialdehyde, or magnetic resonance images). CONCLUSIONS: The findings of this study suggest that hyperbaric oxygen therapy is not effective in the treatment of exercise-induced muscle injury as indicated by the markers evaluated.
