Objectives: Return to School (RTS) and Return to Activity/Play (RTA) protocols are important in concussion management. Minimal evidence exists as to sequence and whether progression can occur simultaneously. Experts recommend that children/youth fully return to school before beginning RTA protocols. This study investigates recovery trajectories of children/youth while following RTA and RTS protocols simultaneously, with the following objectives: (1) to compare rates and patterns of progression through the stages of both protocols; (2) to evaluate symptom trajectories of youth post-concussion while progressing through stages of RTS and RTA; and (3) to propose a new model for concussion management in youth that involves the integration of Return to Activity and Return to School protocols.
Methods: In a 3-year prospective-cohort study of 139 children/youth aged 5–18 years with concussive injury, self-reported symptoms using PCSS and stage of protocols were evaluated every 48 h using electronic surveys until full return to school and activity/sport were attained. Information regarding school accommodation and achievement was collected.
Results: Sample mean age is 13 years, 46% male. Youth are returning to school with accommodations significantly quicker than RTA (p = 0.001). Significant negative correlations between total PCSS score and stage of RTS protocol were found at: 1-week (r = −0.376, p < 0.0001; r = −0.317, p = 0.0003), 1-month (r = −0.483, p < 0.0001; r = −0.555, p < 0.0001), and 3-months (r = −0.598, p < 0.0001; r = −0.617, p < 0.0001); indicating lower symptom scores correlated with higher guideline stages. Median full return to school time is 35 days with 21% of youth symptomatic at full return. Median return time to full sport competition is 38 days with 15% still symptomatic. Sixty-four percent of youth reported experiencing school problems during recovery and 30% at symptom resolution, with 31% reporting a drop in their grades during recovery and 18% at study completion.
Conclusions: Children/youth return to school faster than they return to play in spite of the self-reported, school-related symptoms they experience while moving through the protocols. Youth can progress simultaneously through the RTS and RTA protocols during stages 1–3. Considering the numbers of youth having school difficulties post-concussion, full contact sport, stage 6, of RTA, should be delayed until full and successful reintegration back to school has been achieved. In light of the huge variability in recovery, determining how to resume participation in activities despite ongoing symptoms is still the challenge for each individual child. There is much to be learned with further research needed in this area.
Concussion has become an epidemic in children and youth. The number of reported head injuries in Emergency Departments among youth playing sport has increased in the past decade by over 40% (1). The symptoms of concussions can often interfere with participation and performance in home, school, and community activities (2, 3). The current consensus for standard concussion management is the six-stage Berlin Return to Play recommendations (2). This statement and much of the literature now suggest a more conservative approach to the management of children/youth with concussion. It is, however, still unclear as to what “more conservative” entails. When they are symptomatic, children and youth are advised to rest for 48 h (4) then gradually resume regular activity with incremental increases in physical and cognitive activity within symptom tolerance (5, 6). Depression and anxiety may result as secondary sequelae if youth are socially isolated and removed from normal activity and participation for prolonged periods of time (7–10). Prolonged rest can lengthen recovery time and contribute to deconditioning (11, 12), therefore protocols for children must contain a balance of activity and rest to promote physical, emotional and cognitive recovery.
Both RTS and RTA protocols for pediatric concussion management should be conservative and individualized (2, 13–19). A number of protocols guiding families and youth through progressive recovery steps for safe Return to School (RTS) and Return to Activity/Play (RTA) have now been developed, are widely-accepted and are important aspects of pediatric concussion management (2, 20, 21).
Given that being a student is the primary occupation of childhood through to young adulthood, an emphasis on returning to school should be a top priority for children and families, more so than return to sport (22, 23). However, to date the emphasis in post-concussion management has been on return to play and sports (20, 21). A medical chart review showed that primary care physicians were providing return to school instructions to only 27.5% of patients as compared to return to sport instructions (51.6% of patients) (24). This imbalance may reflect the absence of research about post-concussive school issues (25, 26) and thus empirical evidence for specific methods and timelines for returning children to school is not yet available. An evaluation surrounding concussion education in Toronto schools found that 77% of responding schools have RTS protocols in place, in contrast to the 92% that had RTA protocols (27).
The CanChild Protocols for Concussion Management for children 5–18 years (Appendices 1, 2 in Supplementary Materials) (19, 28) were originally based on the Zurich return to play protocols and now the revised Berlin consensus recommendations (2). The CanChild protocols also have the same six stages of Return to Activity as the Zurich Return to Play recommendations, but they are more conservative in the way the child moves through the stages and have more detail about activities and intensity associated with each stage. Currently, there is minimal evidence supporting as to the sequence of RTS and RTA, whether they can be achieved simultaneously or whether RTS must be achieved before beginning RTA protocols. The focus now has shifted to the importance of return to school before return to activity/play. The Berlin Consensus (2) states that RTS must be completed before RTA begins, but this is ambiguous in clarifying whether that means fully back to school, or just starting to attend school. Others have suggested similar protocols. The Center for Disease Control and Prevention (29) recommends a gradual and cautious RTS, but does not mention how a RTS protocol can be integrated with a stepwise RTA protocol. Thomas et al. (11) noted that a majority of emergency department physicians instructed patients to rest for 1–2 days before returning to school whereas they instructed beginning a stepwise RTA protocol only after patients' symptoms resolved. Many Ontario school boards have adopted a similar approach, recommending full RTS prior to starting RTA protocols (30).
There is increased understanding, however, that youth may benefit from physical activity prior to complete symptom resolution, particularly among youth who are slow to recover (31–33). Moreover, a multisite, prospective cohort study by Canadian researchers indicates that youth who reported early physical activity post-injury (<7 days) have a 25% decreased risk in developing persistent post-concussive symptoms compared to youth who reported no early physical activity (34). These results suggest that early integration of a RTA protocol with RTS may lead to better health outcomes for youth with concussion.
The current scientific literature regarding concussion management has not adequately addressed how to integrate RTA and RTS protocols post-concussion in youth. Prior to doing so, it is important to understand the recovery trajectories of youth while following both RTS and RTA protocols.
Therefore, the objectives of this study were:
1. To compare rates and patterns of progression through the stages of both protocols;
2. To evaluate symptom trajectories of youth post-concussion while progressing through stages of RTS and RTA.
3. To propose a new model for concussion management in youth that involves the integration of Return to Activity and Return to School protocols.
Participants were recruited between November 2014 and December 2016 through the Emergency Department at McMaster Children's Hospital in Hamilton, community referrals from family health teams or sports medicine clinics. The inclusion criteria were as follows: (1) diagnosed with concussion by a physician within the last year; (2) between the ages of 5–18 years; and (3) still symptomatic at recruitment. Children and youth were excluded from the study if they had a confirmed significant brain injury requiring resuscitation, surgical intervention or admission to the pediatric critical care unit. Informed written consent was obtained from all parents and participants. This study was approved by the Hamilton Integrated Research Ethics Board in Hamilton, Canada.
These analyses are part of a larger prospective cohort study evaluating youth compliance to RTS and RTA concussion management protocols (35). Participating youth were monitored for up to 6-months post-recruitment. Upon enrollment to the study, the RTA and RTS protocols were explained to the participating youth and their parents by research staff including how to proceed through the stages and highlighting the importance of returning fully back to school before returning fully back to activity. The protocols were presented together, and youth were told to follow them both. Study data were collected and managed using REDCap electronic data capture software. While still symptomatic, youth were provided electronic questionnaires every 48 h where they were asked to report their current recovery stage within the RTA and RTS protocols, provide an indication of their level of cognitive and physical activity, and complete the Post-Concussive Symptom Scale (PCSS) (36). When enrolled in the study, participants were asked to record on the PCSS, how they were feeling 1-week prior to the injury. Being symptomatic was then based on the difference between the participants' identified pre-injury status and current reporting of symptoms. Upon symptom resolution, participants were asked to complete the same questionnaires biweekly until their final in-person assessment, which occurred 3-months post-symptom resolution.
Secondary outcomes, including reported school problems, grade changes, and use of school accommodations were also collected.
SAS version 9.4 and SPSS Statistics version 23.0 were used to conduct the data analyses. Demographic and injury information variables are presented with mean and standard deviation (SD), or median and lower and upper quartiles (Q1, Q3, respectively), when distributions are highly skewed.
A Spearman's rank order correlation analysis was used to investigate the relationship between a child's PCSS score and corresponding stage of RTS/RTA protocols, with a significance level being set as p < 0.02, as adjusted for the comparisons at the three-designated time-points. To approach this analysis comprehensively, three key time points were chosen: 1-week, 1-month and >1-month, because they represent the most commonly reported recovery times in the concussion literature (2, 37), and they reflect the symptom recovery strata in the CanChild concussion protocols.
T-tests were calculated to determine the mean differences in days to each stage during progress through RTS and RTA to completion. Statistical significance was set at p ≤ 0.05. All data were tested for normality using the Shapiro-Wilk test.
The characteristics of all participants are shown in Table 1. The final sample consisted of 139 children and youth aged 5–18 included 64 boys (46%) and 75 girls (53%) with a mean age of 13.4 years. Sport-related injury was the most prevalent cause of injury (74%). Of these injuries, 28% occurred during recreational play in gym class or at recess, 27% were hockey-related, and 14% were basketball-related.
This was the first concussion for 58% of the participants. At recruitment, median time since injury was 7.8 days (with Q1 and Q3 being 3.0 days and 33.0 days, respectively) whereas the mean time since injury was 34.8 days with the minimum and maximum time being 2.9 h and 320.9 days, respectively. Fifty six percent were in the slow to recover group, that is symptoms persisting longer than 1-month. It should be noted that the recruitment sample purposely included a heterogenous sample of youth with possible time from injury any time within in 1 year post as long as they were still symptomatic. This was reflected in the large variability in symptom duration profiles.
The median return time to stage 3 of RTA was 25.8 days and 12.6 days to RTS. The median time to RTA step 6, full return to activity or sports competition, was 38.5 days (Table 2) with a median return to school time of 35.3 days (p = 0.000) (Figure 1). The median time in stage 3 RTA was 0 days (mean 12.3 days) while median time in stage 3 of RTS was 12.6 days (mean 14.9) (Table 3). Table 4 shows the paired sample t-test for time to stages 3 and 5 and 6 for RTA and RTS.

Table 5 depicts the PCSS at stages 3 RTA/RTS and Stage 6 RTA and Step 5 RTS. The symptom score decreases over time, but symptom scores are consistently higher for RTS than RTA. Fifteen percent of participants were still reporting symptoms upon full return to activity, stage 6 RTA, while, 21% of participants were still symptomatic at stage 5 of the RTS protocols.
The Spearman's rank order correlation analysis showed significant negative associations between the total PCSS score and the stage of RTS/RTA protocols at 1-week (r = −0.376, p < 0.0001; r = −0.317, p = 0.0003), 1-month (r = −0.483, p < 0.0001; r = −0.555, p < 0.0001), and 3-months (r = −0.598, p < 0.0001; r = −0.617, p < 0.0001).
Sixty-four percent of youth reported experiencing school problems during recovery and 30% at symptom resolution with 31% reporting a drop in their school grades during recovery and 18% at study completion. Seventy four percent of parents reported their child was receiving school accommodations during recovery from concussion.
Days spent at each stage of recovery and time to attain each stage of recovery in Tables 2, 3 show that these times are comparable despite huge variability. The time difference between days to RTS and RTA are statistically significant with RTS being quicker. But overall the median time for both full return to school and full competition is just over 1 month. The trajectory of PCSS symptom scores decreases as stage increases, demonstrating a positive recovery trend as youth progress at their own pace through the stages of protocols showing continuous improvement without harmful effect or significant regression in stages or increase in symptoms while they follow RTS and RTA at the same time. Of note is that symptoms scores are higher in RTS stages and youth are more symptomatic on completing RTS (21%) than RTA (15%). This is understandable as youth are returning to school more quickly and not too concerning as long as they are receiving school accommodations, as seen in 74% of this study sample, so that they can continue with school while symptomatic, avoiding unnecessary academic failure and the resulting anxiety it produces for the youth. As expected, time to move through stages and time in each stage is quicker for the youth in strata one, recovery within 1 week, and strata 2, recovery within 1 month, with longest recovery times in the slow to recover group (Table 2) (38–40). The fact that youth return to school sooner than return to activity including contact sport is in line with the recommendations that youth should return to school before return to sport (2, 20, 41), except that in our study they are doing them in unison but at different rates. It is recommended that RTS stages should be followed in conjunction with the RTA protocol (17–19), as suggested in Figure 2. Stages 1–3 can be carried out simultaneously. After stages 1–3 there is more variability in youth recovery (Table 2) and more risk in the activity stages. It is suggested that RTS should then proceed up to full return to school attendance and performance, stage 5 RTS, before moving onto stage 4–6 in RTA. If a youth cannot participate fully in his or her academic program, then he or she should not be playing full contact or step 6 full activity and contact sport (2). As long as youth are active and participating, they do not have to go to full risk and contact sport (17–19, 42). In this way they can concentrate on getting back to full academic achievement while avoiding physical risk, though still enjoying and benefiting from some physical activity (43–46). We now know depression can affect youth who are not allowed to participate (7, 47). Therefore, the balance and compromise is to participate in both school and physical activity until higher level cognitive activity is required and higher level risk is present in higher stages of RTA protocol. At this point higher priority should be given to academic success (22) which is vital to future vocational opportunities and then proceed to higher risk physical activity as in stages 4–6 of RTA (2, 48).
The success of this approach is also greatly dependent on the school accommodations which we saw in 74% of youth. The accommodations allowed youth to progress successfully with both RTS and RTA. As presented in Table 2, the numbers of youth that have problems throughout recovery (64%) drops significantly by the end of symptom resolution (30%) and accommodations throughout by the school probably are likely a significant factor in this trend. It is interesting that quicker recovery of symptoms does not mean less problems as 43% of youth who recovered within a month had school problems as compared to 22% of those who had symptom resolution after 1-month post-injury. The fact that school problems decrease as recovery continues does not support the need to only complete school re-entry before activity resumption.
There are several limitations with this present study. There are inherent limitations with the self-report method and the current analyses were unable to confirm the accuracy of the self-reported symptoms and stage of guidelines. Missing data and those lost to follow-up and different numbers of youth completing each stage make analyses challenging. In addition, the huge variability in times to reach stages affects the normal distribution of the data, so the analyses had to be adjusted for this phenomenon. However, we deliberately chose to include youth with varying times post-injury as long as they were symptomatic in order that a realistic spectrum of recovery could be explored.
Youth return to school faster than they return to play in spite of the self-reported, school-related symptoms they experience while moving through the protocols. Youth can progress simultaneously through the RTS and RTA protocols during the early stages 1–3. Considering the numbers of youth having school difficulties post-concussion, full contact sport, stage 6, of RTA, should be delayed until full and successful reintegration back to school has been achieved. In light of the huge variability in recovery, determining how to resume participation in activities despite ongoing symptoms is still the challenge for each individual child. There is much to be learned with further research needed in this area.
