The forgotten radial nerve: A conceptual framework for treatment of lateral elbow pain

Lateral elbow pain is a prevalent musculoskeletal overuse disorder that has serious consequences for musculoskeletal health, occupational performance, and overall healthcare burden. Available treatment options (traditional therapy and steroid injections) have been studied rigorously, yet supporting evidence is weak. The majority of treatment options available are targeted at the local pathology of the common extensor tendon as the apparent source of pain, and do not adequately address the cause, the source of overuse, and mechanism of injury.

The purpose of this paper is to describe a novel approach, a regional interdependence model, to reduce symptoms of upper extremity musculoskeletal overuse in populations at risk by addressing a broader systematic approach versus a localized symptom driven approach for the assessment and treatment of lateral elbow pain.

The proposed framework - Think in nerve length and layers (TINLL)- accounts for nerve tension and muscle balance in the entire extremity. In this paper we describe the application of the TINLL model for assessment and treatment of SRSN irritation in individuals with lateral elbow pain and propose a method for treatment and for further studies. The proposed treatment approach combines mobilization with movement, elastic taping, and isometric exercises to address impairment at each level: joint alignment, neural tension, and the superficial sensory nervous system.

Our findings of reduced pain with a relatively small number of therapy sessions in a small retrospective cohort of patients using the TINLL framework for assessment and treatment supports further formal study of this approach in a larger cohort with longer follow-up to determine effectiveness compared to current treatments.

Future studies will test and compare the efficacy of the TINLL framework and model of treatment on the short- and long-term outcomes in individuals with chronic lateral elbow pain compared to traditional therapy.
