Summary
Patients with type II diabetes, especially those with peripheral neuropathy, exhibit altered hip joint torques. This suggests an increased susceptibility to lower limb injury and disability in this population.
Area of Science:
- Biomechanics
- Diabetology
- Neurology
Background:
- Diabetes mellitus and peripheral neuropathy are associated with reduced joint torques.
- Peripheral joint torque deficits are a known complication, but hip joint function requires further investigation.
Purpose of the Study:
- To evaluate isometric and concentric peak torques of the hip joint.
- To compare hip joint torques in individuals with type II diabetes with and without peripheral neuropathy against healthy controls.
Main Methods:
- Participants included 27 individuals with type II diabetes (15 without neuropathy, 12 with neuropathy) and 15 healthy controls.
- Motorized dynamometry was used to measure isometric and concentric peak torques for hip flexion, extension, adduction, and abduction.
- Measurements were performed on the non-dominant leg.
Main Results:
- Hip extension and abduction concentric peak torques were lower in diabetic patients with peripheral neuropathy compared to those without neuropathy and controls.
- The angle of peak torque for hip extension was significantly greater in patients with diabetes and peripheral neuropathy.
- The angle of peak torque for hip flexion was lower in patients with diabetes and peripheral neuropathy.
Conclusions:
- Torque parameters of the hip joint differ between individuals with type II diabetes (with or without neuropathy) and healthy subjects.
- Diabetic patients, particularly those with peripheral neuropathy, face a higher risk of lower limb injury and functional disability.

01:23Types of Building Separation Joints
600
Building separation joints divide large or complex building structures into smaller, discrete units that can move independently. These joints are categorized into three types: volume-change joints, settlement joints, and seismic separation joints.
Volume-change joints address the effects of expansion and contraction due to temperature and moisture variations. They are strategically placed at discontinuities in a building's mass where cracking is most likely and are spaced about 150 to 200...

01:22Diabetes Mellitus: Type 2 and Gestational
4.4K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Torque is an important quantity for describing the dynamics of a rotating rigid body. We see the application of torque in many ways in the world, such as when pressing the accelerator in a car, which causes the engine to apply additional torque on the drivetrain. Here, we define torque and provide a framework to create an equation to calculate torque for a rigid body with fixed-axis rotation.
Torque can be considered as the rotational counterpart to force. Since forces change the translational...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

01:15Torque Free Motion
806
The torque-free motion refers to the movement of a rigid body in space when no external torques are acting upon it. This type of motion can be observed in environments where there are no external forces or frictions, like in outer space. For example, a rotation of Mars in space is a torque-free motion. Mars is an axisymmetric object, meaning it has an axis of symmetry along which it rotates, designated as the z-axis. The rotating frame of reference is defined such that the center of mass of...

When a mechanic tries to remove a hex nut with a wrench, it is easier if the force is applied at the farthest end of the wrench handle. The lever arm is the distance from the pivot point (the hex nut in this case) to the person’s hand. If this distance is large, the torque is higher. Only the component of the force perpendicular to the lever arm contributes to the torque. Therefore, pushing the wrench perpendicular to the lever arm is more advantageous. If multiple people apply force to...
