Current Primary Outcome Measures  ICMJE
 (submitted: February 17, 2017)
Pain [ Time Frame: 4 months ]
An 11-point verbalize NRS will be used to assess the subject's upper or lower extremity pain the day of each assessment as well as during therapy sessions. The 0 to 10 NPS has been found to be valid and reliable in many patient populations including the musculoskeletal population[37] and has been recommended for inclusion in the core NIH Toolbox for use with adults[38].

Current Secondary Outcome Measures  ICMJE
 (submitted: February 17, 2017)
  • Temperature [ Time Frame: 4 months ]
    The temperature at three locations (different for upper and lower extremity) will be recorded with an infrared thermometer (Exergen DT-1001RS Infrared Dermal Thermometer with Remote Sensor, Exergen Corp, Watertown, Massachusetts) on both the involved and uninvolved extremities.
  • Range of Motion (ROM) [ Time Frame: 4 months ]
    Active and/or passive ROM of the involved joints will be assessed using an electronic goniometer, and the reference of "normal" will be the non-involved limb. A measurement will be taken, but also the result will be dichotomously categorized as within 95% of opposite side - YES or NO.
  • Pain Medication [ Time Frame: 4 months ]
    An 11-point verbalize NRS will be used to assess the subject's upper or lower extremity pain the day of each assessment as well as during therapy sessions. The 0 to 10 NPS has been found to be valid and reliable in many patient populations including the musculoskeletal population[37] and has been recommended for inclusion in the core NIH Toolbox for use with adults[38].
  • Global Rating of Change (GRC) [ Time Frame: 4 months ]
    The GRC, a self-report instrument, assesses subjective perception of the efficacy of a particular treatment and the significance of that change [39]. A 15-point Likert type scale ranging from 1 (very great deal worse) to 15 (a very great deal better) and a 6-point Likert type scale ranging from 1 (a tiny bit important) to 6 (a very great important) will be used. The GRC is used to determine the minimal clinically important differences and will be used in this study to assess the participants' perceived magnitude of changes following the 30 minute combined NIN/CES treatment and again after each physical therapy or occupational therapy session for range of motion and pain.
  • The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale [ Time Frame: 4 months ]
    The LANNS assessment helps identify whether or not a patient exhibits neuropathic pain. The instrument consists of five self-report and two clinician administered sensory function items that assess dynamic mechanical allodynia and altered pin-prick threshold (PPT). Weighted scores for the seven items are binary (yes or no) and summed, giving a total score between 0 and 24. In terms of diagnostic validity, during the validation study this assessment yielded a sensitivity of 85% and specificity of 80%[
  • National Institutes of Health Patient Reported Outcomes Measurement Information Systems (PROMIS) 29 [ Time Frame: 4 months ]
    Emotional The PROMIS 29, a self-reported measure, assesses health-related quality of life (HRQOL) in seven domains (physical function, anxiety, depression, fatigue, sleep disturbance, social role satisfaction, pain interference, pain intensity). The instrument utilizes a 7-day recall period and consists of eight questions on a Likert-type scale, ranging from 1 to 5 , except for the pain intensity scale, which ranges from 0 to 10.
  • Lower Extremity Functional Scale(LEFS) [ Time Frame: 4 months ]
    The LEFS, originally described by Binkley et al, provides global assessment of function related specifically to the lower extremities.[50] It is one self-report outcome measure that can capture adverse impact on function from multiple injuries or specific locations in the lower extremity. It consists of 20 questions total related to functional activities, each with a possible score ranging from 0 to 4, where 0 indicates that the activity cannot be performed at all and 4 indicates that the activity be performed with no limitations. The total maximum score is 80 points, indicating no limitations with any of the functional tasks. It has been shown to be valid, reliable, and responsive to change in various patient populations and in different body regions in the lower extremity (ankle, knee, and hip).[50-52]
  • Quick Disabilities of the Arm, Shoulder, and Hand (Quick DASH [ Time Frame: 4 months ]
    The DASH is an 11-item self-report measure that assesses a subject's perceived ability to complete twenty-one upper extremity functional activities using a 5-point Likert scale. The cumulative Quick DASH score is scaled from 0 to 100, with higher scores indicating increased disability. The DASH is well tested and has been validated and found reliable in many different upper limb musculoskeletal disorders[45-48]. The Minimally Clinically Important Difference (MCID) for the Dash is 10.83 points, and for the QuickDash is 15.91 points.

Descriptive Information
Brief Title  ICMJE Combining CES Alpha-Stim and InterX for Optimized Rehabilitation Following Extremity Immobilization
Official Title  ICMJE The Clinical Feasibility of Combining Cranial Electrotherapy Stimulation (CES Alpha-Stim) and Non-invasive Interactive Neurostimulation (InterX) for Optimized Rehabilitation Following Extremity Immobilization
Brief Summary This study will be aimed at assessing the feasibility of a dual-device treatment prior to a rehabilitation session for an orthopaedic injury requiring immobilization, and its impact on improving outcomes and decreasing the risk for development of neuropathic pain. The investigators will evaluate the clinical feasibility and effectiveness of incorporating the Alpha-Stim and Inter-X treatment into a standard rehabilitation protocol to address risk factors associated with the development of neuropathic pain (i.e., pain, range of motion, and skin temperature) as well as its impact on reduced pain medication.
Detailed Description

Once patients provide consent and we have determined that they meet inclusion criteria the process will occur as follows:

  1. Participants will be administered baseline demographic and standard medical history questionnaires, including information about prescription medication use. In addition, participants will fill out baseline self-report outcomes and be administered the (LANSS) Pain Scale. Range of motion and temperature will also be assessed during the initial session. Some of these measurements are standard of care and would be filled out by the participant even if the participant were not participating in the study.

Usual CARE The usual care aspect of this study is the delivery of the pain treatment (NIN and CES) as is commonly used at the Center for the Intrepid. The experimental aspect is the combined delivery of the treatment, and the use of sham treatment as a control. The treatment (NIN and CES) will be delivered in a pragmatic fashion, with treatment delivered in conjunction with rehab visits and lasting approximately 4-weeks total. Each session will last approximately 20-40 minutes long, and will most often be delivered in conjunction with their rehab visit (physical therapy or occupational therapy) that occurs anywhere from 1 to 3 times each week.

STRICTLY RESEARCH The experimental aspect of the study will be the comparison of combined treatment (NIN + CES), standard NIN with sham CES, to standard care alone. Before initiation of treatment participants will be randomized to either NIN + CES, NIN + Sham CES, or standard care only immediately after the immobilization device (cast, brace, etc) has been removed. Randomization with be performed with a random number gerator. All groups will continue with their own rehabilitation as indicated throughout the entire course of the study treatment, and beyond as indicated by their therapist. The investigators will keep track of rehab appointments and visits, but not control for them.

3. At the 1-month follow-up, all participants will fill out the same self-report outcome measures from baseline, to include prescription pain medication and be administered the LANSS pain scale. Range of motion and temperature will also be assessed.

4. At the 2 and 4-month follow-up the same assessments will again be administered. If the participant has completed formal therapy prior to the 2 and 4 month follow-up time points the participant will be asked to return to the clinic to complete these assessments. Participants may be contacted by telephone or email, if agreeable, to provide a reminder for the return appointment(s).

5. Outcomes will be compared between the three groups at each time point (i.e., initial, one month, two months, four months).

6. All participants will be followed out to 4 months.

Although every attempt will be made to collect data at these specific times, due to the variability of participant and clinic schedules, the actual timing of collection may vary (+/- 1 week) and some of the proposed measures may not be collected at all time points.
