“…We did not seek to make comparisons between treatment arms of the PROVE trial as this has been previously reported [18]. Our findings agree with previous studies in the literature, showing that increasing kyphosis severity is positively correlated with increased age, number of OVFs and pain, and negatively correlated with back muscle endurance and functional reach [2,13,14,30]. We found participants with hyperkyphosis were responsive to physiotherapy, regardless of the type of treatment administered in the PROVE trial, and importantly demonstrated significant clinically-relevant reductions in thoracic curvature.…”

“…Since the lumbar spine is inherently more mobile than the thoracic spine region [ 21 ], it might be assumed that the tolerability of the lumbar region is more to accept the repeated and persistent forward bending postures. On the other hand, the specific anatomy nature of the spinal extensor muscles leads to the special motor control of these muscles to provide the possibility of the independent movement pattern in different segments of the spine [ 22 , 23 ]. The motor control independency could prove the variability seen in the adaption behavior of the thoracic and lumbar regions.…”

“…This shows that there is a possible relationship between decreasing the amount of fast muscle fibers and the thoracic kyphosis angle improvement. On the other hand, numerous studies showed a negative relationship between muscle strength and hyper kyphosis angle [ 22 , 29 , 30 ]. Since the spinal extensor muscles are often more postural and endurance type, most researchers have focused on the correlation between the strength of these muscles and the hyper-kyphosis posture [ 29 , 30 ].…”

Thoracic and Lumbar Sagittal Spinal Curvature Adaptations between Elite Iranian Road and Speed Cyclists

Background: Despite existing some research on the effects of professional cycling on cyclist’s spinal curvature angles, no research is available concentrating on possible differences in various types of professional cycling. Road (outdoor) and speed (indoor) cyclists have different anthropometric and predominant postures during cycling. The current study aims to investigate if cyclists with different types of cycling may have dissimilar spinal curvature adaptations. Objective: Forty-eight male subjects, including 16 elite road cyclists, 16 elite sprint cyclists and 16 non-athletes as the control group were recruited in this non-experimental study. Material and Methods: In this cross-sectional study, a spinal mouse was used to measure the thoracic and lumbar curvature angles in standing position. Results: The mean values of thoracic kyphosis and lumbar lordosis angles were found as follows 48.3±7.2º & -20.3±7.2º for elite road cyclists; 46.6±8.1º & -22.5±7.7º for elite sprint cyclists; and 37.5±4.1º & -19±6.3º for the control group. The results confirmed that both the road and sprint cyclists showed significantly more hyper-kyphosis posture in their thoracic region when compared to the control group (p<0.05). Conclusion: All road cyclists showed no significantly higher degrees of thoracic angle relative to the sprint cyclists (p>0.05). However, all the cyclists and the control groups showed a normal range of lumbar lordosis angle. As a conclusion, the results of this study confirmed that an elite cyclist may predispose these subjects to the risk of hyper-kyphotic posture. The road cycling may result in more hyper-kyphosis due to the longer time, spent in flexed position.

“…[ 9 ] While there is no accepted threshold differentiating normal from abnormally increased kyphosis angle, a kyphosis angle greater than 40° is often used to define hyperkyphosis. [ 10 11 ] Females may be at higher risk of hyperkyphosis due to hormone changes with menopause and other sex-related factors such as poor spinal extensor muscle quality,[ 12 ] low spinal muscle strength[ 13 ] and endurance,[ 14 ] low bone mineral density, vertebral fractures,[ 15 ] and the weight of hanging breasts. [ 10 ] Once kyphosis reaches 50°, the risk for falls[ 16 17 ] and fractures increases,[ 18 ] either of which can have devastating consequences in reducing the physical function.…”

Identifying factors that impact physical function in older populations is important for the maintenance of good health with aging. Age-related hyperkyphosis, an excessive curvature in the thoracic spine, affects up to 40% of the older adults and is more common in older females than males. An association of age-related hyperkyphosis with impaired physical function has been reported in numerous studies, however, other studies have reported that a greater magnitude of kyphosis did not associate with impaired physical function. Given the inconsistencies regarding the impact of hyperkyphosis on physical function, the purpose of our study is to perform a systematic review of the existing studies in order to better describe the association between hyperkyphosis and physical function. Prospective and retrospective cohort, case-control, and cross-sectional studies which measure physical function by valid functional tests and questionnaires in older females will be included. We will search Scopus, ISI Web of Science, Cochrane Library, PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PEDro databases. Studies will be searched and then selected by two independent reviewers based on quality assessment tools from the National Heart, Lung, and Blood Institute (NHLBI). A meta-analysis will be conducted if data reported for individual studies allow. Specifically, if two or more individual studies provide measures of central tendency and variability from any of the categories of physical function measures, data will be gathered for meta-analysis. If a meta-analysis is not possible, data will be synthesized and described in a narrative form by size and variability of effect, direction of effect, and association with hyperkyphosis.
