Introduction[edit | edit source]
The purpose of this document is to summarize the clinical assessment of the patient diagnosed with lateral epicondyle tendinopathy. Initially, the assessment consists of history, objective and subjective examination, chief complaints in order to confirm the diagnosis. The toolkit will even include differential diagnosis, the process of identifying causes/risk factors of lateral epicondyle tendinopathy and functional examination.
Risk factors[edit | edit source]
There are potential risk factors associated with developing lateral epicondyle tendinopathy LET. These can be further classified as non-modifiable and modifiable risk factors
Non-Modifiable Risk Factors[edit | edit source]
These are the factors which cannot be changed
- Metabolic Disorder
- Familial Disorder
- Genetics – variants in connective tissue health more likely to be susceptible to LET
- Systemic Inflammatory Disease
- Spondyloarthropathy (SpA) is generally associated with enthesis disorders, more commonly in the load bearing tendons of lower limbs compared to upper limbs.
- SpA (SCREEND’EM) – acronym for a useful screening tool to assist in identifying individuals that would benefit from further medical investigation for SpA.
Modifiable Risk Factors[edit | edit source]
These are the factors which can be worked on and measures can be taken to change them. They are the exposures /behavior's which lowers or increases the person's risk of lateral elbow epicondylitis.
- Smoking – current and past history
- Active Group – Overuse from repetitive and forceful recreational and occupational activity.
- Inactive/Sedentary Group
- More likely to have overuse response to unaccustomed loads from ADLs, or decline in tendon load capacity (age, activity, or lifestyle factors).
- Previous shoulder injury
- Rotator cuff weakness ipsilateral side
History[edit | edit source]
Lateral elbow pain which is related to over use. It is not always associated with sport and can occur through any activity that involves wrist extension, pronation or supination.
Subjective Symptoms[edit | edit source]
Symptoms provoked by activity. Symptoms are usually localized to lateral elbow, or referred along the extensor/supinator muscle groups of the forearm. Extensor weakness and reduced grip strength may be present and could be linked to pain provocation.
Biopsychological factors[edit | edit source]
Persistent LET pain may involve behavioral and psychosocial factors contributing to nervous system sensitivity (peripheral and central). There is evidence that psychological variables (catastrophization, signs of distress) can increase LET symptoms. In patients with psychosocial drivers, treatment programs should consider providing pain neuroscience education, as well as addressing cognitive and behavioral barriers.
Objective Signs[edit | edit source]
During the assessment it is important to record clinical observations not only symptoms. Below we discuss objective signs relevant to LET.
Upper Quadrant Screening Exam[edit | edit source]
Upper quadrant musculoskeletal conditions are defined as pain in the arm , shoulder and neck and they are not due to trauma or underlying systemic disease.
|Upper quadrant Screening Exam||Contributing Factors|
|Shoulder||Rotator cuff weakness myofascial trigger points (MTrP), Neuropathic tender points|
|Elbow , Forearm||Grip weakness MTrP, Neuropathic tender points|
|Abnormal Neural Tension(Neurodynamics)||Peripheral nerve – Radial bias|
Palpation[edit | edit source]
Palpation is an important part of the assessment process and can used to determine any abnormalites such as swelling, pain or tenderness, and skin temperature.
In LET, palpation is primarily performed at the extensor carpi radialis brevis tendon insertion at the lateral epicondyle. It may also include the extensor carpi radialis longus and extensor digitorum communis insertion.
Mills Test[edit | edit source]
- Start position
- Shoulder neutral, elbow 90 degrees, forearm pronated, wrist fully flexed.
- Operator gradually passively extends elbow towards zero degrees, maintaining forearm pronation or wrist flexion. Monitor pain over lateral elbow.
Maudsley Test[edit | edit source]
- Start Position
- Shoulder neutral, elbow 90 degrees , forearm pronated and wrist in neutral position.
- The therapist resist middle finger extension. Monitor pain over lateral elbow.
Cozen's Test[edit | edit source]
- Start Position
- Shoulder neutral, elbow 90 degrees , forearm pronated, wrist neutral. Combined resistance of wrist extension, radial deviation.
- The patient is asked to move the wrist to dorsal flexion and the therapist provides resistance to this movement. The test is positive if pain is elicited over the lateral elbow.
Thomsen Test[edit | edit source]
The Thomsen test is an isometric resistance test for the extensor muscle group. It is a variation of cozen's test.
- Start position
- Shoulder 60 degrees flexion, elbow 0 degrees, forearm pronated, wrist extended 30 degrees.
- Isometrically resist wrist extension at the dorsum of hand. A positive is recognised if pain is observed at the lateral elbow.
Imaging[edit | edit source]
Imaging such as ultrasound (US) and magnetic resonance imaging (MRI) may be useful, particularly for patients whose symptoms are inconsistent with LET and are not responding to conservative interventions, to ascertain whether there are structural changes in tendon consistent with LET. Imaging may also assist to ‘rule out’ the tendon as a source of pathology, and investigate for other intra/extra articular conditions.
Differential Diagnosis[edit | edit source]
It can be difficult to accurately diagnose LET as there are many other conditions with similar clinical symptoms. Below is a list of other possible causes and conditions:
- Posterolateral rotary instability due to laxity of collateral ligaments
