Gait & Posture
|December 15, 2018
Summary
Female dancers exhibit altered spine posture and increased range of motion (ROM) compared to non-dancers. However, low back pain (LBP) did not correlate with these spinal kinematics, suggesting limited clinical generalizability.
Area of Science:
- Biomechanics
- Kinesiology
- Dance Science
Background:
- Spine posture, range of motion (ROM), and movement asymmetry are linked to low back pain (LBP).
- These factors may disproportionately affect dancers due to repetitive spine movements, though evidence is limited.
Purpose of the Study:
- To investigate the influence of dance participation and low back pain (LBP) on spinal kinematics in female individuals.
Main Methods:
- A cross-sectional study analyzed multi-segment spinal kinematics in 60 female participants (21 dancers, 39 non-dancers; 33 with LBP, 27 without).
- A nine-camera motion analysis system captured standing posture, ROM, and movement asymmetry during side bending and trunk rotation tasks.
- Two-way ANOVA was used to compare kinematic differences between dancers/non-dancers and individuals with/without LBP.
Main Results:
- Dancers showed a flatter upper lumbar angle and greater frontal plane ROM in the upper lumbar and lower thoracic spine compared to non-dancers.
- No significant differences were found between groups for transverse plane ROM or movement asymmetry.
- Low back pain (LBP) symptoms did not significantly affect any kinematic measures, nor did the interaction between dance group and LBP.
Conclusions:
- Female dancers exhibit distinct spinal posture and increased ROM in specific segments compared to non-dancers.
- The observed kinematic differences were minimal, and no association was found between LBP and spinal kinematics.
- Standard clinical measures of posture, ROM, and asymmetry offer limited generalizable insights into the impact of dance or LBP on spinal kinematics.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

15.4K
When an object moves with constant acceleration, the velocity of the object changes at a constant rate throughout the motion. The kinematic equations of motions are derived for such cases where the acceleration of the object is constant. The first kinematic equation gives an insight into the relationship between velocity, acceleration, and time. We can see, for example:

01:28Ending Relationships
189
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

The second kinematic equation expresses the final position of an object in terms of its initial position, the distance traveled with the initial constant velocity, and the distance traveled due to a change in velocity. Similar to the first kinematic equation, this equation is also only valid when the acceleration is constant throughout the motion of an object.

In mechanics, when one observes a rigid body in rotational motion with constant angular acceleration, it is possible to establish equations for its rotational kinematics. This process resembles how linear kinematics are dealt with in simpler motion studies.
For instance, imagine a point A on a rigid body engaged in circular motion. The translational velocity of this particular point can be calculated by taking the time derivatives of the displacement equation, which essentially measures the...

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
