Sample Answer
Even force distribution through joints:
- Correct alignment ensures forces are distributed evenly across joint surfaces rather than concentrated in one area, minimising stress on articular cartilage.
Reduced stress on ligaments/tendons:
- Proper alignment keeps ligaments and tendons working within their normal anatomical range, preventing overstretching and uneven loading.
Optimal muscle length-tension relationships:
- Aligned joints allow muscles to work at their ideal length, providing efficient movement control and joint support.
Maintenance of normal movement patterns:
- Correct alignment enables smooth joint motion along natural anatomical pathways, promoting efficient movement patterns.
Prevention of compensatory movements:
- Proper joint positioning prevents other body parts from taking on excessive load to compensate for poor alignment.
