It has been known for quite some time that athletic performance is intimately connected to psychosocial views, beliefs, and readiness to perform. It is still rarely held in high regards when compared to physical impairment testing amongst musculoskeletal and performance experts.
GOAL:
Provide tests & measures regarding psychosocial return to sport testing
Ways to to implement these test & measures seamlessly into your practice
IMAGINE:
Athletes that you believe were held back from their previous performance levels due to psychological factors…
The question is, “was it ever addressed?”
CURRENT:
Psychosocial return to sport research is highly focused on outcomes with ACL reconstruction (ALC-R) surgery
Purpose of this surgery:
Fix the mechanical failure in the body
Retrain the athlete back to full function and sport
Why does standardized psychosocial testing become more of a specialized subpopulation?
Many athletes are not returning to or surpassing prior level of function due to possible psychosocial barriers.
These barriers can greatly harm:
Overall surgical outcomes
Life enjoyment
Postoperative complications & comorbidities
Statistics:
21% of postoperative athletes do not return to sport at all
45% do not return to the same pre-injury level of elite sport participation
40-50% of patients do not even return to recreational sports participation
Overall:
Post-operative patients get less physical exercise
High rate of post-surgical ACL-R weight gain (3.8x more likely to be overweight in 3-10 years after ACL-R surgery)
Lack of return to sports activities with increased weight gain
>50% of ACL-R patients will develop increased knee OA at a much faster rate than normal
Evidence:
In this first study (Lentz et al., 2015), physical impairments [quadriceps index (QI), quadriceps strength/body weight (QSBW), hamstring: quadriceps strength ratio (HQ ratio)], pain intensity, self-report of function (International Knee Documentation Committee (IKDC), and psychosocial (Tampa Scale for Kinesiophobia–shortened form (TSK-11) measurements were collected at 6 months and 1 year after surgery using 73 athletes with ACL Reconstruction. At 1 year the subjects were divided into ‘‘return-to-sport’’ or ‘‘not return-to-sport’’ subgroups based on their self-reported return to preinjury sport status. Patients in the “not return-to-sport” subgroup were subcategorized as NRTS-Fear/Confidence if fear of reinjury/lack of confidence was the primary reason for not returning to sports, and all others were categorized as NRTS-Other.
This study showed that there is a strong association between a high TSK-11, a low QSBW, and a low IKDC at 1 year in the NRTS-Fear/Confidence subgroup vs the “return-to-sport” group or the NRTS-Other group. This suggests there is a strong psychologically mediated functional limitation with full post-surgical return to sport. Overall, this study supports a growing body of evidence highlighting the importance of measuring and addressing pain-related fear of reinjury, in addition to physical impairments, in standardized return-to-sport criteria (10).
Another study (Arden et al., 2013) looked at 187 recreational and competitive athletes, who were given the psychological readiness to return to sport, fear of re-injury, and sport locus of control subjective questionnaires. They were also asked to estimate of the number of months it would take to return to sport both preoperatively and at 4 months postoperatively. At 12 months post ACL-R only 56 athletes (31%) had returned to their preinjury level of sports participation. The results support that psychological responses before surgery and in the early recovery (4 months) were significantly associated with returning to preinjury level of sport at 12 months. This suggests that attention to psychological recovery should start to be implemented in return to function criteria, and start early, even possibly before surgery. This study concludes that screening for maladaptive psychological thought process’ in athletes prior to and soon after surgery may help clinicians identify those athletes at risk of not returning to their preinjury level of sport by 12 months (5).
This next study (Arden et al., 2014) shows how important psychosocial testing can be even with a population that is participating at a recreational level. In this cross-sectional study 164 subjects completed multiple questionnaires at 1–7 years after ACL-R surgery. The questionnaires included a knee self-efficacy (K-SES), health locus of control (MHLOC-C), psychological readiness of return to sport (ACL-RSI), and a fear of re-injury (TSK). At follow-up only 40% (66/164) had returned to their preinjury activity level. Those who did return had a more positive psychological response, reported better knee function in sport and recreational activities, perceived a higher knee-related quality of life, and were more satisfied with their current knee function. In those that did not return, the main reasons identified were not trusting the surgical knee (28%), fear of a new knee injury (24%), and poor knee function (22%). Psychological readiness to return to sport, measured with the ACL-Return to Sport after Injury scale ACLR-SI was most strongly associated with returning to the preinjury activity. Meaning if the athlete has a lower K-SES and ACL-RSI score and a higher TSK-11 score, then this may lead to a lower return to preinjury activity 1-7 years post surgically. This study suggests that including interventions aimed at improving these aspects in postoperative rehabilitation programs could be warranted to improve the rate of return to sport and recreational activities (3).
Next, there is a very pertinent systematic reviews (Te Wierike et al., 2013) which support psychosocial testing as an integral piece regarding return to sport and recreation. This systematic review shows that high scores on the “internal health locus of control” and “self-efficacy” tests were useful cognitive factors to facilitate recovery. Also, this study showed that postoperatively ACL-R athletes with a low level of fear of reinjury had the best knee outcomes when returning to sport. In addition, athletes who returned to sport exhibited less fear of reinjury and were more experienced athletes when compared to athletes who did not return to sport (11).
Finally, a meta-analysis of 25 studies, evaluating over 942 injured competitive athletes, uncovered three core themes across the studies chosen. The first is that emotion is associated with, and connected to, rehabilitation outcomes. The second is that there is importance in cognitions associated with rehabilitation outcomes. Third is that those cognitions correlate to behaviors associated with rehabilitation outcomes. These studies support that injury and performance-related fears, anxiety, and confidence were the most common psychosocial factors associated with rehabilitation outcomes. Therefore, practitioners need to recognize that an injured athlete’s thought, feelings, and actions may very well influence the outcomes of rehabilitation, as well as readiness to return to play.
It can be seen that progressing our profession forward will involve a deep understanding of athletes biopsychosocial connection, and our ability to tease out which is the most limiting factor associated to suboptimal return to function/sport. Our current interpretation of successful rehab may be overly simplified, and practitioners must ensure that injured athletes are physically and psychologically ready to return to sport, with an increased emphasis in non-physical impairments. Practitioners should not assume that physical and psychosocial recovery from injury occurs within the same timeframe or that they are both improving with increased function. They need to be separately and specifically tested (9). As we head into an era focused on true biopsychosocial treatment and individualized sport specific progressive care, it is evident that a holistic approach to patient’s recovery should be addressed to attain the best possible outcomes.
