Abstract Objective. To evaluate the relationship between load-carrying on the head and the development of degenerative change in the cervical spine. Design and subjects. A case-control study was performed with 35 individuals who had carried loads on their head (carriers) and 35 persons who never had carrier loads on their head (non-carriers). A scoring system was utilized for the assessment of the degenerative change in the cervical spine at the C3/C4, C4/C5, C5/C6 and C6/C7 levels on lateral… 
The Effect of Head Loading on Cervical Spine in Manual Laborers
TLDR
Carrying a load on the head leads to accelerated degenerative changes, which involve the upper cervical spine more than the lower cervical spine and predisposes it to injury at a lower threshold, Thus, alternative methods of carrying loads should be proposed.
A LONGITUDINAL STUDY ABOUT THE MORPHOLOGY OF THE CERVICAL VERTEBRAL BODY IN COLLEGIATE AMERICAN FOOTBALL PLAYERS
TLDR
The faster growth rate in experienced or backs groups suggests that higher mechanical stress to the cervical spine and younger start of AF caused degeneration.
Women with late whiplash syndrome have greatly reduced load-bearing of the cervical spine. In-vivo biomechanical, cross-sectional, lateral radiographic study.
TLDR
The study shows, for the first time, that the cervical spine in women with LWS predominately functions such as a rigid cylinder when loaded, and implies thatThe cervical column is extremely weak in the LWS and that the superficial neck muscles must compensate and act as rigid stabilizers.
Biomechanical effect of C5-C6 intervertebral disc degeneration on the human lower cervical spine (C3-C7): a finite element study.
TLDR
It is emphasized that the degenerated disc alters the degenerating and normal segments' motion and loading patterns, and the abnormal increase in facet joint force in the degenerate models threatened to accelerate the degeneration in the normal segments.
Effect of axial load on the cervical spine: a study of Congolese woodbearers
TLDR
The cervical spine radiographically of 72 women between 24 and 78 years of age who had carried wood on their head for a mean of 12 (5–41) years was studied and the findings were compared with those of 44 women between 21 and 80 years ofAge who served as controls.
Relationship between Cervical Sagittal Parameters and Health Related Quality of Life in Cervical Degenerative Disc Diseases
TLDR
This study aimed to evaluate the relation between the radiological cervical sagittal parameter changes with the presence and severity of symptoms as well as quality of life in CDDD individuals, and provided radiographic guidelines for the assessment and management of cervical spine patients.
Functional, Radiological and Sagittal Balance Outcomes in Surgically Treated Degenerative Cervical Disc Diseases
TLDR
It could be concluded that cervical sagittal imbalance arising from regional and/or global spinal sagittal malalignment plays an independent role in exacerbating adjacent segment pathomechanics after multilevel fusion and should be considered during cervical fusion surgical planning.
Cervical spine disorders in farm workers requiring neck extension actions
TLDR
Findings suggested that ES of the cervical spine is a risk factor for degenerative cervical spine disorders, and DCS and the aging process are risk factors for cervical myelopathy.
Impact of Nursing Physical Training Program on Clinical Outcomes for Patients Undergoing Cervical Spine Surgery
TLDR
Applying nursing physical training program significantly enhanced the studied patients’ pain intensity, gait, muscle strength, reflexes, and neck disability index postoperatively than their controls.
Comparison of biomechanical performance of single-level triangular and quadrilateral profile anterior cervical plates
TLDR
The quadrilateral anterior cervical plate (ACP) is used extensively in anterior cervical discectomy and fusion (ACDF) to reconstruct the stability of the cervical spine and prevent cage subsidence but the screws have high peak stress value, thereby increasing the risk of screw slippage and fracture.

Relationship between load carrying on the head and cervical spondylosis in Ghanaians.
TLDR
It is concluded that cervical spondylosis is not exclusively an ageing phenomenon, but that regular heavy load carrying on the head plays an aetiological role.
A study of weight transmission through the cervical and upper thoracic regions of the vertebral column in man.
TLDR
The role of the neural arch in weight transmission in the cervical and upper thoracic regions of the vertebral column has been investigated and it was found that at C2 level the compressive force acting on the superior articular surfaces was transmitted to the inferior surface of the body and to the two inferior articular facets.
Spinal stability as defined by the three-column spine concept
TLDR
The three-joint motion segment is characterized by a triangular disposition of joints with opposing joint spaces, thus supporting the articular orthogonal triangulation concept and having a clinical relevance in the field of spinal growth, changes consequent upon wear in spinal joints and clinical instability.
Measurement of Intervertebral Disc Space Height
TLDR
A wide variation In IVD was found in 132 patients who had previously undergone surgical procedures for nerve root compression from herniated discs at the L4–5 and L5–S1 levels 10 or more years before.
Prevalence rates and odds ratios of shoulder-neck diseases in different occupational groups.
TLDR
Examination of published reports shows clearly that certain job titles are associated with shoulder-neck disorders, and high rates and aetiological fractions for rotator cuff tendinitis and tension neck syndrome suggest that preventive measures could be effective.
Lumbar intervertebral disc disease in Africans.
TLDR
There is a considerable difference in the incidence of the condition in the two races, and back and leg pain can be very crippling so that it is reasonable to suppose that a fair percentage of those afflicted will seek medical care.
The pathogenesis of cervical spondylosis.
Cervical spondylosis is a generalized disease process affecting all levels of the cervical spine. Cervical spondylosis encompasses a sequence of degenerative changes in the intervertebral discs,
