The Electrodiagnostic Evaluation of Neck Pain

C5 nerve root palsy (without prior cervical decompression) case series: 9 patients with critical delay to presentation

BACKGROUND

Distinguishing between cervical nerve root and intrinsic shoulder pathology can be a difficult task given the overlapping and often coexisting symptoms.

OBJECTIVE

The objective of this study was to highlight the often-complicated presentation of these symptoms and the subsequent potential for delay in care regarding this subset of patients.

METHODS

A total of 9 patients, managed by one of two different surgeons, were identified with a history of C5 nerve root palsy. A chart review was conducted, and the following information was recorded: presenting complaint, time from symptom onset to diagnosis, time from symptom onset to presentation to a spine surgeon, first specialist seen for symptoms, non-spinal advanced imaging and treatment conducted before diagnosis, preoperative and postoperative exam, time to recovery, and type of surgery.

RESULTS

We observed an average time from onset of symptoms to presentation to a spine surgeon to be 31.6 weeks. These patients' time to full recovery after cervical decompression was 15 weeks.

CONCLUSION

: We observed a critical delay to presentation in this series of patients with C5 nerve palsy. C5 nerve palsy should remain an elemental part of the differential diagnosis in the setting of any shoulder or neck pain presenting with weakness.

Spurling's test - inconsistencies in clinical practice

Objective: The purpose of this study was to investigate the methodology, interpretation, and perceived value of Spurling's test toward diagnosis/classification and treatment. Methods: An anonymous web-based survey was made available to physical therapist members of the Academy of Orthopaedic Physical Therapy of the American Physical Therapy Association. Based on video demonstrations of technique and symptom distribution, questions included preferred method, criteria for test interpretation, and perceived value of Spurling's test and other examination findings toward clinical decision-making. Professional profile data were also collected. Results: Among the 452 participants completing the survey, no method of testing was preferred by more than 37%, with ipsilateral lateral flexion, rotation, and extension with compression being most frequently preferred followed by ipsilateral lateral flexion with compression at 32%. Proximal provocation of symptoms only without distal symptoms was interpreted as a positive test by 67%. Participants rated Spurling's test of moderate to low value toward diagnosis/classification and treatment. Discussion: Inconsistency with methodology and interpretation of Spurling's test is suggested to be pervasive in physical therapist practice. While an optimal test methodology has yet to be identified, result interpretation does have a basis for clarification toward diagnosis/classification and reduction of unwanted variance in practice.

Zoster-associated segmental paresis in a patient with cervical spinal stenosis

Segmental zoster paresis is a rare complication of herpes zoster, characterized by focal motor weakness that does not always present simultaneously with skin lesions. Zoster paresis can be easily confused with other neuromuscular or spinal diseases. This case report describes the case of a 72-year-old woman with herpes zoster and cervical spinal stenosis at the same spinal level, where it was difficult to distinguish segmental zoster paresis from cervical radiculopathy combined with motor neuropathy. Although segmental zoster paresis in the upper extremity is rare, it should be included in the differential diagnosis of segmental pain and weakness in the extremities, especially in older or immunocompromised patients. Correct diagnosis is required, to avoid unnecessary surgery and allow timely antiviral treatment.
