Vertebral Column: Regions and Curvature01:16

Vertebral Column: Regions and Curvature

3.7K
The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Deformations in a Symmetric Member in Bending01:18

Deformations in a Symmetric Member in Bending

172
When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.
When the member is segmented into tiny cubic elements, it is observed that the primary stress...

Chest Physiotherapy01:24

Chest Physiotherapy

485
Chest Physiotherapy (CPT) is a therapeutic technique used in respiratory care to improve ventilation, clear bronchial secretions, and enhance the efficiency of respiratory muscles. This therapy includes three primary procedures: postural drainage, percussion, and vibration. It can be performed on spontaneously breathing patients and those who are intubated and mechanically ventilated.
Purpose
CPT is primarily used for patients with excessive bronchial secretions who have difficulty clearing...

Plastic Deformations01:14

Plastic Deformations

90
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...

Design of Prismatic Beams for Bending01:23

Design of Prismatic Beams for Bending

243
The design of prismatic beams, structural elements with a uniform cross-section, focuses on ensuring safety and structural integrity under load. The design process begins by determining the allowable stress, either from material properties tables, or by dividing the material's ultimate strength by a safety factor. This safety factor is essential for accommodating uncertainties, and varies depending on the material—timber, steel, or concrete—with each having unique strength and...

Temperature Dependent Deformation01:12

Temperature Dependent Deformation

150
In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...

Summary

New underwear-mounted braces effectively reduce rounded shoulder posture (RSP) and improve muscle activity. The inner brace design showed the most promising results for RSP correction and muscle balance.

Area of Science:

  • Orthopedics
  • Biomechanical Engineering
  • Physical Therapy

Background:

  • Rounded shoulder posture (RSP) is linked to shoulder pain, impingement, and frozen shoulder.
  • Altered scapular positioning in RSP affects muscle activity, necessitating corrective interventions.
  • Conventional shoulder braces are effective but often bulky and inconvenient for daily wear, particularly for women concerned with aesthetics.

Purpose of the Study:

  • To evaluate the immediate effects of three novel underwear-mounted braces on RSP.
  • To determine which brace design is most effective in reducing RSP and modifying upper trapezius (UT) and lower trapezius (LT) muscle activity.
  • To assess the potential of discreet, integrated braces as a solution for RSP management.

Main Methods:

  • Eighteen patients diagnosed with RSP participated in the study.
  • Measurements included RSP amount and UT/LT muscle activity before and after interventions.
  • Interventions involved scapular posterior tilting (SPT) exercises using three brace types: X strap, X + 8 strap, and inner brace.

Main Results:

  • All three underwear-mounted braces significantly reduced RSP compared to baseline.
  • The X + 8 strap and inner brace demonstrated superior RSP reduction compared to the X strap.
  • The inner brace exhibited the lowest UT muscle activity and the highest LT muscle activity, indicating optimal muscle engagement.

Conclusions:

  • Underwear-mounted braces offer a discreet and potentially effective solution for managing rounded shoulder posture.
  • The inner brace design shows particular promise for reducing RSP and improving muscle activation patterns.
  • Further research is needed to assess long-term efficacy, comfort, and aesthetic integration for widespread adoption.
