The primary objective of this investigation is to assess the effectiveness of transcutaneous electrical nerve stimulation applied using VECTTOR to reduce the symptoms of Duchenne Muscular Dystrophy and reduce the impact of DMD upon the participants' quality of life.
The primary outcome measures will include:
Muscle Strength and Joint Range of Motion Testing - All muscle and joint testing was performed at the MedCenter Therapy clinic in Houston, Texas. JTech computerized testing system was utilized including Goniometry, Grip testing, Inclinometry, Muscle Testing and Joint Range of Motion testing occurred on Day 0, 30, 60, 90, 180, and repeated at 12 months to determine muscular strength and joint Range of Motion. JTech computerized testing system was chosen on the basis of reliability and accuracy. At each of the testing intervals, the testing was administered by the same technician with the same equipment to all of the participants. Inter-and intra-tester reliability of the JTech computerized testing system has been the subject of multiple studies. Each of which found high ICCs (>0.93) for both inter- and intra-tester reliability.
All sleep studies were performed at Sleep Diagnostics of Texas in The Woodlands, Texas. Prior to the clinical trial, all of the participants spent two nights in the sleep unit and their sleep study examinations were performed. The second night was used as the Day 0 data. Sleep, breathing, arousals and limb movements were scored manually according to guidelines set forth by the American Academy of Sleep Medicine. The sleep studies were repeated at 6 months and 1 year.

| VECTTOR | Device | The VT-200, or VECTTOR system, delivers electrical stimulation via electrodes on the acupuncture points of a patient's feet/legs and hands/arms to provide symptomatic relief of chronic intractable pain and/or management of post-surgical pain. Once these electrodes are placed, the machine determines the appropriate choice of stimulation by automatically measuring body temperatures through the use of thermistors placed on the fingers during a testing sequence. |

| Percent Change in Range of Motion From Baseline to 180 Days | Range of Motion (ROM) testing (Wireless Tracker System) - All muscle and joint testing was performed using the JTech computerized testing system, including Goniometry, Grip Testing, Inclinometry, Muscle Testing and Joint Range of Motion. Testing occurred at Baseline (Day 0), 30, 60, 90 and 180 days to determine changes in joint Range of Motion. JTech computerized testing system determined the joint range of motion by radio signals from a goniometer measuring movement of the participants' joints. 44 separate tests were performed for Range of Motion for each participant at each time interval. The results from the range of motion tests were averaged the percent change from baseline to 180 days. Efficacy is defined as an increase in range of motion. | Baseline to 180 days |

| Percent Change in Muscle Strength | Muscle strength testing (Wireless Tracker system) - All muscle strength testing was performed using the JTech computerized testing system, including Goniometry, Grip Testing, Inclinometry, Muscle Testing and Joint Range of Motion. Testing occurred at Baseline (Day 0), 30, 60, 90, and 180 days to determine changes in muscle strength. JTech computerized testing system determined the muscle strength by radio signals from a strain gauge measuring strength of the participant's muscles. 44 separate tests were performed for muscle strength for each participant at each time interval. Efficacy is defined as an increase in the strength measurement (pounds) from Baseline to 180 days. |

| Percent Change in Sleep Quality Arousal Statistics Index (ASI) From Baseline to 180 Days | Sleep / Arousal Statistics Index (ASI) description: Sleep Studies were obtained twice before beginning the study. The second sleep study data was used as baseline. A follow up sleep study was obtained after 6 months (180 days) of Active or Placebo VECTTOR treatment. Sleep, breathing, arousal(s), and limb movements were scored manually according to guidelines of the American Academy of Sleep Medicine. The efficacy of the outcome measure of ASI is demonstrated by a percent improvement between Baseline and 180 days. The ASI is measured by the number of times sleep is interrupted per hour. |
