NCT02383472

Brief Summary

A double blind randomized trial of light-emitting diode (LED) therapy for patients suffering from mild traumatic brain injury (mTBI). Patients seen in the Sports Concussion Clinic with cognitive symptoms lasting for greater than 4 weeks will be randomized to either placebo therapy (controls) or treatment with LED therapy (cases). Both cases and controls would complete post-concussion symptom scales Delis-Kaplan Executive Function System (D-KEFS), and ImPACT studies on entry into the study and at weeks 3 and 6, or earlier if their symptoms resolve before the end of the 6 week period.

Outcome Measures

Primary Outcomes (1)

  • Mean Difference in Change in Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) Score at Baseline and 6 Weeks.

    The primary outcome is mean difference on composite scores of Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) between entry into the study and completion of treatment (visit 18, week 6) for both the LED group and the placebo group. The mean difference is calculated by taking the mean of differences of the entry scores minus the 6 week scores. There are 5 composite scores on the ImPACT test; verbal memory, visual memory, visual motor speed, reaction time, and symptom score. The ranges for these subscales are as follows: verbal memory and visual memory: 0-100, visual motor speed: 0-60, reaction time: 0-1.0, and symptom score: 0-132. A higher verbal memory, visual memory, and visual motor speed represent a better outcome, while a lower reaction time and lower symptom score represent a better outcome.

    From baseline to 6 weeks

Secondary Outcomes (4)

  • Mean Difference in Change in Delis-Kaplan Executive Function System (D-KEF) Color-Word Interference and Trail Making Test Performance at Weeks 3 and 6.

    From baseline to 3 weeks and from baseline to 6 weeks

  • Mean Difference in Change in Delis-Kaplan Executive Function System (D-KEF) Verbal Fluency Performance at Weeks 3 and 6.

    From baseline to 3 weeks and from baseline to 6 weeks

  • Mean Difference in Change in Total Post Concussion Symptom Score (PCSS) at Weeks 3 and Weeks 6.

    From baseline to 3 weeks and from baseline to 6 weeks

  • Mean Difference in Change in Total Cognitive Symptom Score at Weeks 3 and Weeks 6

    From baseline to 3 weeks and from baseline to 6 weeks

Study Arms (2)

MedX Health Console model 1100

EXPERIMENTAL

The treatment group will receive LED treatments over 6 weeks, 3 times per week, totaling 18 visits. All treatments will take place at Boston Children's Hospital. The cluster heads are applied to frontal, parietal, and temporal areas. Each cluster head is applied to the forehead/scalp areas for up to 10 minutes. There will be two 10-minute LED/placebo treatment periods per visit, each with different cluster head placements on the head/scalp.

Device: MedX Health Console model 1100

MedX Health Console model 1100-placebo

PLACEBO COMPARATOR

Subjects enrolled in the placebo group will be on the same schedule as the treatment group. The placebo group will receive LED placebo over 6 weeks, 3 times per week, totaling 18 visits. All placebo patients will take place at Boston Children's Hospital. The cluster heads are applied to frontal, parietal, and temporal areas. Each cluster head is applied to the forehead/scalp areas for up to 10 minutes. There will be two 10-minute LED/placebo treatment periods per visit, each with different cluster head placements on the head/scalp.

Device: MedX Health Console model 1100-placebo

Interventions

MedX Health Console model 1100DEVICE

All treatments will be administered using the MedX Health Console model 1100. These units were cleared by the FDA as non-significant risk in 2003 and approved for home treatment use in 2005 "for temporary increase in local blood flow circulation . . . for temporary relief of minor muscle and joint aches." Cluster heads are 2 inches in diameter. Each contains 9 red (633nm wavelength) diodes and 52 near infrared (870 nm wavelength) diodes. LED cluster heads would be applied to the frontal, parietal and temporal areas, as well as the mid sagittal suture line

MedX Health Console model 1100-placeboDEVICE

The placebo machine is identical in appearance as the treatment machine; It vibrates, warms, and does everything the treatment machine does except it does not have LED lights on the marker, therefore it cannot emit light. Subjects enrolled in the placebo group will be on the same schedule as the treatment group. They will have two, 10 minute treatments, three times a week totaling 18 visits. The placebo allows the researchers to isolate the effect of the study treatment. If patient's in the LED treatment group fare significantly better than those in the placebo treatment group, the study helps support the conclusion that the LED therapy is effective.
