Multimodal impairment-based physical therapy for the treatment of patients with post-concussion syndrome: A retrospective analysis on safety and feasibility

Exertional Tolerance Assessments After Mild Traumatic Brain Injury: A Systematic Review

OBJECTIVE

To review the literature to identify and summarize strategies for evaluating responses to physical exertion after mild traumatic brain injury (mTBI) for clinical and research purposes.

DATA SOURCES

PubMed and EBSCOhost through December 31, 2016.

STUDY SELECTION

Two independent reviewers selected studies based on the following criteria: (1) inclusion of participants with mTBI/concussion, (2) use of a measurement of physiological or psychosomatic response to exertion, (3) a repeatable description of the exertion protocol was provided, (4) a sample of at least 10 participants with a mean age between 8 and 65 years, and (5) the article was in English. The search process yielded 2685 articles, of which 14 studies met the eligibility requirements.

DATA EXTRACTION

A quality assessment using a checklist was conducted for each study by 2 independent study team members and verified by a third team member. Data were extracted by one team member and verified by a second team member.

DATA SYNTHESIS

A qualitative synthesis of the studies revealed that most protocols used a treadmill or cycle ergometer as the exercise modality. Protocol methods varied across studies including differences in initial intensity determination, progression parameters, and exertion duration. Common outcome measures were self-reported symptoms, heart rate, and blood pressure.

CONCLUSIONS

The strongest evidence indicates that exertional assessments can provide important insight about mTBI recovery and should be administered using symptoms as a guide. Additional studies are needed to verify optimal modes and protocols for post-mTBI exertional assessments.

Non-pharmacological rehabilitation interventions for concussion in children: a scoping review

PURPOSE

To summarise the extent, nature, and quality of current scholarly literature related to non-pharmacological, rehabilitation interventions following concussion, or mild traumatic brain injury in children.

METHODS

An electronic search was conducted from 1987 to 24 October 2017. Studies were included if they met the following criteria: (1) full text, peer reviewed, and written in English, (2) original research, (3) diagnosed concussion or mild traumatic brain injury, (4) described the evaluation of an intervention, (5) the outcome was a concussion impairment, and (6) the mean/median age was under 19. Quality assessment using the Down's and Black criteria was conducted.

RESULTS

Twenty-six studies published between 2001 and 2017 were identified. Interventions included rest, active rehabilitation, exercise, vestibular, oculomotor, cervicospinal therapy, education, early intervention, telephone counselling, mobile health application, Web-based Self-Management program, multimodal physical therapy, cognitive behavioural therapy, transcranial direct current stimulation, and acupuncture. The quality assessments ranged from poor to good.

CONCLUSIONS

The literature describing interventions following concussion in children is scarce. While both positive and negative results were obtained, there were methodological concerns in most studies limiting the ability to draw conclusions. Interventions incorporating aerobic exercise show promise as a concussion management strategy. Implications for rehabilitation Few studies have examined rehabilitation interventions for youth following concussion. Research ranging from rest to exercise highlights the uncertainty of the field. Low quality research limits the generalizability of results. The use of physical activity appears to be an emerging area of interest. Individualised, aerobic exercise should be used as part of clinical management.

Rest and treatment/rehabilitation following sport-related concussion: a systematic review

AIM OR OBJECTIVE

The objective of this systematic review was to evaluate the evidence regarding rest and active treatment/rehabilitation following sport-related concussion (SRC).

DESIGN

Systematic review.

DATA SOURCES

MEDLINE (OVID), CINAHL (EbscoHost), PsycInfo (OVID), Cochrane Central Register of Controlled Trials (OVID), SPORTDiscus (EbscoHost), EMBASE (OVID) and Proquest DissertationsandTheses Global (Proquest) were searched systematically.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Studies were included if they met the following criteria: (1) original research; (2) reported SRC as the diagnosis; and (3) evaluated the effect of rest or active treatment/rehabilitation. Review articles were excluded.

RESULTS

Twenty-eight studies met the inclusion criteria (9 regarding the effects of rest and 19 evaluating active treatment). The methodological quality of the literature was limited; only five randomised controlled trials (RCTs) met the eligibility criteria. Those RCTs included rest, cervical and vestibular rehabilitation, subsymptom threshold aerobic exercise and multifaceted collaborative care.

SUMMARY/CONCLUSIONS

A brief period (24-48 hours) of cognitive and physical rest is appropriate for most patients. Following this, patients should be encouraged to gradually increase activity. The exact amount and duration of rest are not yet well defined and require further investigation. The data support interventions including cervical and vestibular rehabilitation and multifaceted collaborative care. Closely monitored subsymptom threshold, submaximal exercise may be of benefit.
