Summary
Advancing age significantly increases cervical joint position error (JPE) in asymptomatic individuals. Older adults exhibit greater JPE compared to younger adults across all movement directions, indicating age-related declines in proprioception.
Area of Science:
- Biomedical Engineering
- Gerontology
- Kinesiology
Background:
- Cervical joint position error (JPE) reflects proprioceptive acuity.
- Age-related changes in sensorimotor control are well-documented.
- Understanding age-related JPE is crucial for assessing functional decline.
Purpose of the Study:
- To quantitatively assess the association between age and cervical JPE.
- To compare cervical JPE between young and older asymptomatic adults.
Main Methods:
- 230 asymptomatic subjects (17-70 years) participated.
- Cervical JPE measured using the active movement angle reproduction test with a digital inclinometer.
- JPE assessed in flexion, extension, side-bending, and rotation.
Main Results:
- Significant positive correlations between age and cervical JPE across all movement directions (r = 0.71–0.84).
- Older subjects (≥50 years) demonstrated significantly larger JPE than younger subjects (P < 0.001).
- Age was strongly associated with increased cervical JPE.
Conclusions:
- Advancing age is significantly associated with increased cervical JPE.
- Older asymptomatic individuals exhibit diminished proprioceptive accuracy compared to younger counterparts.
- Findings highlight age-related sensorimotor changes impacting cervical proprioception.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:10Ankle Joint
3.3K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:20Structural Classification of Joints
8.0K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

01:23Knee Joint
3.5K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:28Articulations of the Vertebral Column
3.4K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
