A case of pseudo-angina pectoris from a pectoralis minor trigger point caused by cross-country skiing

Pectoralis minor syndrome

Pectoralis minor syndrome (PMS) is defined as compression of the brachial plexus (BP) nerves, axillary artery, and axillary vein under the pectoralis minor muscle. The symptoms of PMS resemble supraclavicular compression of the neurovascular bundle, with shoulder, neck, chest, and arm pain, and paresthesia and weakness in the arm and hand. The diagnosis of PMS can be confused with other upper extremity pain syndromes. A detailed history, including occupation, daily activities, sports, and trauma, is critical in the diagnosis, together with physical examination findings. Radiological examinations, including direct radiography, computed tomography, magnetic resonance imaging, and electrophysiological tests, are also helpful for the differential diagnosis. Arterial and venous Doppler ultrasound, including dynamic investigation, can display arterial and venous compression. Injection tests are used to confirm the definitive diagnosis. Conservative treatment is successful in most patients, and surgical treatment is considered in unresponsive cases.

Rare Isolated Pectoralis Minor Tear from a Noncontact Injury: Case Report and Review of the Literature

Isolated pectoralis minor tears are rare orthopedic injuries often in weightlifters or contact sports and should be included in the differential when evaluating athletes with anterior shoulder pain. These injuries are often mistaken for pectoralis major muscle stains and tears. Advanced imaging with MRI helps define the anatomic location and grade of injury. Treatment is usually conservative with full return to activity after a brief period of rest for a few weeks. The purpose of this article is to present a case report and review of the literature on the clinical evaluation, imaging, and treatment of an isolated pectoralis minor tears.

Feasibility of using the patient-reported outcomes measurement information system in academic health centers: case series design on pain reduction after chiropractic care

OBJECTIVE

The purpose of this study was to test the utility of Patient-Reported Outcomes Measurement Information System (PROMIS) as a resource for collecting data on patient-reported outcomes (PRO) within academic health centers at a chiropractic college; and, to describe changes in PRO following pragmatic chiropractic care incorporating instrument-assisted soft tissue mobilization (IASTM) on pain symptoms.

METHODS

This was a pre-post intervention design without a control group (case series) involving 25 patients (14 females and 11 males; 40.5 ± 16.39 years, range 20-70 years) who completed their chiropractic care and their baseline and post-treatment pain assessments. The pragmatic chiropractic care intervention included both spinal manipulation and IASTM to treat pain symptoms. PRO's were collected using PROMIS to measure pain behavior, pain interference and pain intensity.

RESULTS

The average pre-post assessment interval was 33 ± 22.5 days (95% CI, 23-42 days). The durations of treatments ranged from one week to 10 weeks. The median number of IASTM treatments was six. Pre-post decreases in T-scores for pain behavior and pain interference were 55.5 to 48.4 and 57.7 to 48.4, respectively (P < .05). Only 12 patients had a baseline T-score for pain intensity greater than 50. The pre-post decrease in pain intensity T-scores for these 12 patients was from 53.4 to 40.9.

CONCLUSION

Within the limitations of a case series design, these data provide initial evidence on the utility of PROMIS instruments for clinical and research outcomes in chiropractic patients.

Evaluation and treatment of musculoskeletal chest wall pain in a military athlete

BACKGROUND AND PURPOSE

Athletes reporting chest pain are challenging to diagnose and equally challenging to treat. The majority of chest pain is musculoskeletal in origin, yet differentiating these from other more serious conditions should be the initial primary focus. The ability to reproduce the patient's symptoms aids in the differential diagnostic process. The purpose of this case report is to illustrate the use of dry needling (DN) to aid in the diagnosis and treatment of focal chest wall pain.

CASE DESCRIPTIONS

A 22 year-old male military athlete with anterior chest pain, refractory to traditional physical therapy, was evaluated and treated with dry needling.

OUTCOMES

Favorable results were achieved as demonstrated by clinically meaningful improvements in the Patient Specific Functional Scale, the Global Rating of Change score, and his physical performance which allowed this athlete to return to competition and military training.

CONCLUSION

Dry needling in the hands of properly trained providers may aid in diagnosis and treatment of focal chest wall syndromes.

LEVEL OF EVIDENCE
