Description

Upon referral for lateral elbow pain, two schedulers will look at the referral and consult with the study co-investigators to decide what group they should be assigned to based on past medical treatment for lateral elbow pain. The schedulers will have a script they read over the phone to the patients. This will be part of the usual call. At this point, patients do not need to decide whether or not to participate; they are just introduced to the study. Upon arrival for their appointment, the scheduler will introduce the study again to the patient and the patient will be given the opportunity to watch a short video on an approved IPad. This closed-captioned video will provide details of the study and patients will watch the video in a treatment room. After watching the video, the co-investigators will review the consent form and ask the participant if they have any questions. Those subjects that agree to participate will sign the consent form, thus consenting to participate. Those subjects who do not agree to participate will still receive treatment.

Once consent is obtained, subjects will be assigned to either the TINLL group or the traditional treatment and given a research ID number. Once assigned to a group, the therapist in charge of that group will perform the following assessments at the initial visit: numerical rating scale for pain (NRS), patient-rated tennis elbow evaluation (PRTEE), one pain free grip strength with extended elbow and pronated forearm (strength number recorded), and one 3-jaw pinch max effort (pain level and strength number recorded). Regardless of group assignment, all subjects will undergo these assessments at the initial visit. Following the assessments, subjects will begin either the TINLL or the traditional treatment group. Subjects will be assessed at the initial visit, 2-week visit, and 4-week visit and the same assessments will be administered by the same therapist. After the 4-week visit, subjects can opt to switch groups if they choose to do so. These visits described below are regular standard of care intervals. If a subject requires additional visits beyond what is listed below, the subject will be excluded from the study and will receive needed care and billed according to standard practices.

Treatment for the TINLL group will be 1x every 1-2-weeks for 4-6 weeks and consists of a combination of the following depending on the patient:

• radial head mobilization
• biceps tendon mobilization with movement to address joint alignment, neural tension, and the superficial sensory nervous system.
• elastic tape cross fiber inhibition 50% stretch over distal biceps
• elastic tape radial head stabilization with 80% stretch
• biceps stretching/lengthening
• pectoralis major stretching
• scapular strengthening
• triceps and supinator strengthening
• ergonomic strategies

Additional treatments may be considered. These include:

• techniques for relieving radial nerve tension (instrument-assisted soft tissue mobilization (IASTM), silicone cup gliding)
• radial nerve taping from dorsal thenar muscle to C7 on stretch (10%).

The home exercise program for this group includes biceps inhibition tape, radial head stabilization tape, and isometric strengthening triceps/supination (dosing = 1-2 sets/day for 8 reps).

Treatment for the traditional treatment group will be 1x every week for 4-6 weeks and will consist of a combination of the following depending on the patient:

• stretching of the wrist extensors
• isometric, concentric, and/or eccentric strengthening of the finger extensors, wrist extensors, pronator, and supinator muscles
• elbow joint manipulation or mobilization (such as mobilization with movement (MWM) as developed by Mulligan)
• soft tissue mobilization techniques to the forearm muscles
• instrument-assisted soft tissue mobilization (IASTM) to the forearm muscles
• rigid taping techniques and elastic taping application as part of a multimodal treatment program focused on common extensors
• ergonomic strategies
• transcutaneous electrical nerve stimulation (TENS)
• wrist orthosis/splinting
• The home exercise program for this group includes extrinsic stretches for wrist extensors (3 reps, 30 sec holds, 1 time/day) and strengthening (dosing = 3 sets of 15 repetitions 1x/day)

Following 1-month of treatment in either group, subjects will be given the opportunity to switch groups.

6-mo following treatment, subjects will be contacted via phone and asked follow-up questions related pain, function (via the PRTEE), use of taping, and use of home exercises.
