Association Between Fear of Pain and Sports-Related Concussion Recovery in a Pediatric Population

Returning to sport after injury: the influence of injury appraisals and post-traumatic stress symptoms on adolescent risk-taking intentions post-injury

OBJECTIVE

How youth think about injury risk can affect their decisions about whether to engage in behaviors that can lead to injury. Appraisals also influence the development of post-traumatic stress symptoms (PTSS), which occur in approximately 20% of children after a medically treated injury. The current study examined how the injury appraisals of youth are associated with the development of PTSS post-skateboarding injury, and if PTSS or perceived benefits of the sport are also associated with youths' intentions to return to the sport.

METHOD

One hundred three youth who had a medically treated skateboarding injury within the last year provided survey data on injury appraisals, PTSS, the benefits of skateboarding, and intentions to return to the sport.

RESULTS

A two-stage moderated statistical mediation path model was specified. In the first stage, there was a positive relationship between pain at injury and PTSS, which was attenuated by the moderator, perceived bad luck. PTSS fully mediated the association between perceived pain at the time of injury and intentions to return to skateboarding. In the second stage of the mediation model, the moderator perceived benefits of skateboarding, reversed the negative relationship between PTSS and intentions to return to skateboarding.

CONCLUSIONS

Skateboarders are a group at risk for injury that can lead to PTSS, and they also are likely to return to the sport despite PTSS. This research identifies factors that impact the decision to return to skateboarding after injury. Limitations of the study and implications for mental health support and injury prevention are provided.

When should an athlete retire or discontinue participating in contact or collision sports following sport-related concussion? A systematic review

OBJECTIVE

To systematically review the scientific literature regarding factors to consider when providing advice or guidance to athletes about retirement from contact or collision sport following sport-related concussion (SRC), and to define contraindications to children/adolescent athletes entering or continuing with contact or collision sports after SRC.

DATA SOURCES

Medline, Embase, SPORTSDiscus, APA PsycINFO, CINAHL and Cochrane Central Register of Controlled Trials were searched systematically.

STUDY ELIGIBILITY CRITERIA

Studies were included if they were (1) original research, (2) reported on SRC as the primary source of injury, (3) evaluated the history, clinical assessment and/or investigation of findings that may preclude participation in sport and (4) evaluated mood disturbance and/or neurocognitive deficits, evidence of structural brain injury or risk factors for increased risk of subsequent SRC or prolonged recovery.

RESULTS

Of 4355 articles identified, 93 met the inclusion criteria. None of the included articles directly examined retirement and/or discontinuation from contact or collision sport. Included studies examined factors associated with increased risk of recurrent SRC or prolonged recovery following SRC. In general, these were low-quality cohort studies with heterogeneous results and moderate risk of bias. Higher number and/or severity of symptoms at presentation, sleep disturbance and symptom reproduction with Vestibular Ocular Motor Screen testing were associated with prolonged recovery and history of previous concussion was associated with a risk of further SRC.

CONCLUSION

No evidence was identified to support the inclusion of any patient-specific, injury-specific or other factors (eg, imaging findings) as absolute indications for retirement or discontinued participation in contact or collision sport following SRC.

More Physical Activity Is Correlated With Reduction in Kinesiophobia for Adolescents With Persistent Symptoms After Concussion

CONTEXT

The relationship between physical activity (PA) and fear of pain with movement (ie, kinesiophobia) during concussion recovery is unknown. Kinesiophobia may limit PA, while PA after concussion may reduce kinesiophobia. Our purpose was to examine the correlation between PA and self-reported kinesiophobia during concussion recovery for adolescents with and without persistent symptoms.

DESIGN

Prospective cohort study of children ages 10-18 years within 14 days of concussion.

METHODS

Participants rated kinesiophobia using the Tampa Scale of Kinesiophobia (TSK) at initial (≤14 d postconcussion) and return to play (RTP) assessments, and wore activity monitors between assessments. Our primary outcome was TSK score change from initial to RTP assessments. We grouped participants based on whether they experienced persistent symptoms (symptoms ≥28 days) or not (symptoms <28 days) and calculated correlation coefficients (Pearson r for normally distributed and Spearman rho for nonnormally distributed variables) between PA variables and TSK change scores.

RESULTS

Among the 41 participants enrolled, 44% developed persistent symptoms (n = 18; age = 14.5 [2.0] y; 50% female; symptom duration = 57.3 [6.2] d; RTP = 66.8 [6.4] d) and 56% did not (n = 23; age = 14.9 [1.8] y; 48% female; symptom duration = 15.2 [1.5] d; RTP = 21.7 [1.9] d). For the persistent symptoms group, greater TSK change scores (mean = -2.5 [5.7] point change) were significantly and moderately correlated with higher daily step count (r = -.60, P = .008) and exercise frequency (r = -.63, P = .005), but were not correlated with exercise duration (ρ = -.12, P = .65). Among the no persistent symptoms group, TSK change scores (mean = -6.0 [5.0] point change) were not correlated with step count (r = -.18, P = .41) or exercise duration (ρ = .10, P = .67), and the correlation with frequency was low and not significant (r = -.34, P = .12).

CONCLUSIONS

Regular PA during concussion recovery, regardless of duration or intensity, may help reduce kinesiophobia for those experiencing persistent symptoms.

Transitory kinesiophobia after sport-related concussion and its correlation with reaction time

OBJECTIVES

To examine kinesiophobia (i.e. fear of movement) among adolescent athletes with concussion compared to controls, and correlations of kinesiophobia with symptoms and reaction time.

DESIGN

Prospective cohort study.

METHODS

We evaluated 49 adolescent athletes twice. The concussion group was assessed within 14 days of injury and at return-to-play clearance. The control group was tested initially and approximately 28 days later. Participants completed Tampa Scale of Kinesiophobia, Post-Concussion Symptom Inventory, and clinical reaction time assessments.

RESULTS

We included 32 concussion participants (15 ± 2 years; 50% female) and 17 controls (16 ± 1 years; 47% female). Acutely (<14 days post-injury), the concussion group reported greater Tampa Scale of Kinesiophobia scores (38.5 ± 5.4 vs. 29.4 ± 6.7; p < 0.001; Cohen's d = 1.54), and a greater proportion of "high" (≥37) scores than controls (69% vs. 6%; p < 0.001). At return-to-play, there were no significant between-group differences (33.3 ± 6.5 vs. 30.8 ± 7.4; p = 0.23; Cohen's d = 0.36); 28% of the concussion group reported "high" Tampa Scale of Kinesiophobia scores. At return-to-play, kinesiophobia was significantly/moderately correlated with clinical reaction time for the concussion group (r = 0.50; p = 0.01).

CONCLUSIONS

Adolescents recovering from concussion commonly reported high kinesiophobia initially postconcussion, while 28% continued to report high kinesiophobia at return-to-play clearance. Additionally, a correlation between Tampa Scale of Kinesiophobia scores and clinical reaction time was observed for the concussion group. This finding would benefit from further study to determine potential perception-behavior relationships following concussion.
