Abstract

Movement patterns may be a factor for manipulating the lumbar load, although little information is yet available in the literature about the relationship between this variable and intervertebral disc pressure (IDP). A finite element model of the lumbar spine (49‐year‐old asymptomatic female) was used to simulate intervertebral movements (L2–L5) of 127 asymptomatic participants. The data from participants that at least completed a simulation of lumbar vertebral movement during the first 53% of a movement cycle (flexion phase) were used for further analyses. Then, for each vertebral angular motion curve with constant spatial peaks, different temporal patterns were simulated in two stages: (1) in lumbar pattern exchange (LPE), each vertebral angle was simulated by the corresponding vertebrae of other participants data; (2) in vertebral pattern exchange (VPE), vertebral angles were simulated by each other. The k‐mean algorithm was used to cluster two groups of variables; peak and cumulative IDP, in both stages of simulations (i.e., LPE and VPE). In the second stage of the simulation (VPE), Kendall's tau was utilized to consider the relationship between different temporal patterns and IDPs for each individual lumbar level. Cluster analyses showed that the temporal movement pattern did not exhibit any effect on the peak IDP while the cumulative IDP changed significantly for some patterns. Earlier involvement in lumbar motion at any level led to higher IDP in the majority of simulations. There is therefore a possibility of manipulating lumbar IDP by changing the temporal pattern with the same ROM, in which optimal distribution of the loads among lumbar levels may be applied as preventive or treatment interventions. Evaluating load benefits, such as load, on biomechanically relevant lumbar levels, dynamically measured by quantitative fluoroscopy, may help inform interventional exercises. [ABSTRACT FROM AUTHOR]

Abstract

The article offers information on the assessment of disability and function in patients with musculoskeletal disorders, discussing the limitations of traditional patient-reported outcome measures and physical assessments. It explores the potential of wearable medical technology, such as smartwatches and smartphone applications, to provide objective and continuous data on patients' physical function, mobility, and health, allowing for better patient care and treatment planning in orthopedics.

Abstract

Study Design: Cross-sectional observational. Background: The use of social media by providers can enhance patient education, complement offline information, facilitate patient support, stimulate brand building, and strengthen the organization's market position. Risks of social media include, but are not limited to, a lack of quality, reliability, misrepresentation of credentials, influence of hidden and overt conflicts of interest, content that may jeopardize patient privacy, HIPAA regulations, and physicians' credentials and licensure. Physicians' use of social media may also expose him/her to lawsuits if providing specific medical advice on media platforms. Objective: To document the social media presence of a broad cohort of spine surgeons, and to discuss the benefits and risks of a social media presence. Methods: Cross-sectional observational of 325 Spine Surgeons from 76 institutions across the US. Description statistic and Pearson's correlation were used to investigate the relationships between the variables. Results: Out of the 325 surgeons, 96% were male with an average age of 51.5 ± 10.7 years and 14.1 ± 9.6 years of experience. The frequency of social media use included 57.2% of surgeons had professional LinkedIn, 17.8% had professional Facebook, and less than 16% had other social media platforms. When combining all platforms together, 64.6% of all surgeons had at least one professional social media platform. 64.0% of these surgeons had no social media activity in the past 90 days, while 19.4% and 10.9% were active once and twice a month, respectively. Surgeon age (P = 0.004), years in practice (P < 0.001), and practice type (P < 0.001) were strongly correlated with social media activity. Conclusions: Given the scarcity of research on this topic and the novelty of the platforms, social media and online services continue to be utilized at a low level by spine surgeons. Issues regarding the risks of privacy issues with social media users continue to be a concern among medical professionals adopting this technology. This can largely be mitigated with the combination of physician education and informed consent from patients. The ability to connect with patients directly, and provide access to high-quality education and information will be of considerable benefit to our field well into the future. [ABSTRACT FROM AUTHOR]
