Developing Neuraxial and Regional Pain Procedural Skills Through Innovative 3-Dimensional Printing Technology.

CONTEXT: Various forms of simulation-based training, including training models, increase training opportunities and help assess performance of a task. However, commercial training models for lumbar puncture and epidural procedures are costly. OBJECTIVE: To assess medical students' and residents' perception of 3-dimensional (3D)-printed lumbar, cervical, and pelvic models for mastering joint injection techniques and to determine the utility of ultrasonography-guided needle procedure training. METHODS: Osteopathic medical students and residents used in-house 3D-printed gel joint models during an injection ultrasonography laboratory for mastering lumbar epidural, caudal epidural, sacroiliac, and facet joint injection techniques. After the laboratory, they answered a 17-item survey about their perception of the importance of the models in medical education and future practice. The survey also evaluated comfort levels with performing joint injections after using the models, overall satisfaction with the models, and likelihood of using models in the future. RESULTS: Thirty-six medical students and residents participated. Both students and residents agreed that 3D-printed models were easy to use, aided understanding of corresponding procedures, and increased comfort with performing joint injections (all P<.001). Most participants (35 [97.2%]) believed that the models were reasonable alternatives to commercial models. Over half felt capable of successfully performing cervical or pelvic (22 [61.1%]) and lumbar epidural (23 [63.9%]) injections. The majority of participants (34 [94.4%]) would like to use the models in the future for personal training purposes. Overall, 100% believed that the 3D-printed models were a useful tool for injection training. CONCLUSIONS: Results suggest that 3D-printed models provided realistic training experience for injection procedures and seemed to allow participants to quickly master new injection techniques. These models offer a visual representation of human anatomy and could be a cost-saving alternative to commercial trainers.

Correlation of Somatic Dysfunction With Gastrointestinal Endoscopic Findings: An Observational Study.

CONTEXT: Gastrointestinal (GI) endoscopy provides a novel means of correlating visceral abnormalities with somatic dysfunction. OBJECTIVE: To assess the correlation of palpatory findings of somatic dysfunction with GI abnormalities determined by endoscopy and to identify which types of somatic dysfunction were most commonly correlated with GI abnormalities. METHODS: In this observational, cross-sectional study, participants who were scheduled to receive an esophagogastroduodenoscopy (EGD), colonoscopy, or both were examined by 2 osteopathic physicians immediately prior to endoscopy for the presence of vertebral tenderness, asymmetry, restricted range of motion, and tissue texture abnormalities (TART findings); tenderness of anterior Chapman reflex points; and tenderness of visceral sphincters. Each type of somatic dysfunction and the somatic dysfunction burden (sum of findings) were compared with the type of endoscopic procedure and abnormal endoscopic findings. RESULTS: Sixty-six adults participated: 43 received an EGD, 40 received a colonoscopy, and 17 received both. The incidence of vertebral TART findings ranged from 70% at T12 to 98% at the sacrum. Participants who received only EGD had a higher somatic dysfunction burden than those who received only colonoscopy and those who received both procedures (P=.002). The incidence of abnormal endoscopic findings ranged from 98% in the stomach to 0% at the ileocecal valve. Statistically significant positive associations were found between specific vertebral TART findings and abnormalities of the esophagus, gastroesophageal junction, pylorus, ascending colon, and sigmoid colon; specific Chapman reflex point tenderness and abnormalities of the esophagus, gastroesophageal junction, pylorus, ascending colon, descending colon, sigmoid colon, and rectum; and specific visceral sphincter tenderness and abnormalities of the duodenum, ascending colon, and sigmoid colon. CONCLUSIONS: The current study found numerous associations between somatic dysfunction and abnormal endoscopic findings. However, the high incidence of vertebral TART findings and the lack of normal controls for many GI regions made establishing meaningful relationships between specific somatic dysfunction and specific GI abnormalities challenging. Future investigations should include more participants to ensure a higher number of normal endoscopic findings and limit the physical examination to elements of somatic dysfunction with a high level of variability between vertebrae within an individual participant and between participants, such as tenderness and tissue texture abnormalities.

Role of osteopathic manipulative treatment in the management of stiff person syndrome.

Stiff person syndrome (SPS) is a rare and disabling central nervous system disorder first described in 1956 and characterized by fluctuating rigidity and stiffness, gait impairment, and painful spasms of the axial and limb musculature. Although an underlying mechanism of impaired synaptic γ-aminobutyric acid-ergic inhibition has been proposed, the exact mechanism remains unclear. The glutamic acid decarboxylase antibody, a marker for SPS, is a strong indication of disease and has been reported in approximately 70% of patients. The current treatment of choice is benzodiazepines and baclofen, both of which reduce motor unit potential firing and, therefore, decrease stiffness and spasms. However, patients continue to have substantial disability with pharmacologic therapy alone. This case report demonstrates the potential of osteopathic manipulative treatment as an adjunct to medication in the management of SPS. By decreasing somatic dysfunction and reducing the frequency of exacerbations, osteopathic manipulative treatment may alleviate the symptoms and overall morbidity associated with this disease.
