“…These findings are in constant with the results reported by Daneshmandi (2010) indicating a significant association between the degree of curvature of the thoracic kyphosis and the degree of scapular protraction [24]. Gary (2012) stated that the increase in thoracic kyphosis is linked to reduced physical function, increased neck pain, and shoulder conditions (e.g., subacromial syndrome) [25]. Briggs (2007) reported that excessive and repetitive overhead activities and abnormal shoulder changes in overhead activities are amongst the prevalent causes of shoulder pain and disability in athletes with overhead activities [26].…”

“…All volleyball players with impingement syndrome (n=11) were selected with the approval of an orthopedist. After determining the range of age (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28), height (175-195), and weight (75-95) of the participants, 11 players with impingement syndrome were included in the test group. Also, 11 volleyball players without impingement syndrome matched for gender and age, height, and weight were included in the control group.…”

This case-control study aimed at comparing the kyphosis angle, position of the shoulder, the strength of rotator cuff muscles, and the range of shoulder motions in volleyball players with and without impingement syndrome. Methods: The participants were 22 male professional volleyball players with at least 5 years of training experience. Eleven volleyball players with impingement syndrome and eleven without impingement syndrome were selected from accessible gyms by simple non-probabilistic sampling. The research tools were a flexible ruler, a measuring tape, a goniometer, a pull-up bar, a dynamometer, and tests to measure the distance between spinal midline and the shoulder, kyphosis angle, flexibility, range of motion, and isometric strength of the shoulder girdle muscles in abduction, adduction, flexion, extension, horizontal adduction, and horizontal abduction. Data were analyzed using SPSS V. 19 software and the Shapiro-Wilk test and independent t-test. Results: There was a significant difference between the two groups in terms of kyphosis angle, the distance between spinal midline and the shoulder, range of motion of the glenohumeral joint in abduction, and isometric strength of the shoulder girdle muscles in abduction, flexion, and extension (P<0.01). However, no significant difference was observed between the two groups in terms of flexibility of the shoulder when lying on the abdomen with arms stretched out in front, endurance in the strength of the shoulder girdle muscles, and isometric strength of the shoulder girdle muscles in adduction, horizontal adduction, and horizontal abduction (P>0.05). Conclusion: The results of this study showed that angle of kyphosis, scapula distance to spine, range of motion of the shoulder, factor profile of a range of motion, and isometric muscle strength of shoulder girdle altered in people with shoulder impingement syndrome, and dysfunctions in these factors may result in shoulder impingement syndrome and athlete performance inefficiency.

“…The cervical flexors consist of sternocleidomastoid (SCM) and anterior scalenes (AS); the SCM travels obliquely across the side of the neck and inserts at the skull (Robinson and Anderson, 2005;Gray and Grimsby, 2012) and the AS origins from the cervical vertebrae C3-C6. The AS functions as a contracting (Bogduk and Mercer, 2000;Puglisi et al, 2007).…”

Little research has been reported on evaluating the safety of the fixation construct in cervical kyphosis correction. In this study, we proposed a principal-strain criterion to evaluate the safety of the fixation construct and validated the modeling method against a retrospective case of anterior cervical discectomy fusion (ACDF). From C2 to T2 vertebra bodies, fixation instruments were reconstructed and positioned as per postoperative computed tomography (CT) scans. Head weight (HW) and various moments estimated from isometric strength data were imposed onto the C2. The postoperative stability of non-surgical segments, deformations surrounding the screw trajectories, and contact slipping on zygapophysial joints were analyzed. The model was validated against the reality that the patient had a good fusion and deformity correction. The ACDF restricted the range of motions (ROMs) of cervical segments and lent stability to vertebra fusion, no failure was found in the finite element (FE) model of cervical vertebrae. The deformation surrounding the screw trajectories were concentrated to the lateral sides of trajectories, recommending that the shape of the anterior cervical plate conforming to the curvature of the vertebra and screws fully inserted into vertebrae reduced the deformation concentration around the screw trajectories.

“…Normal LLA values were found between 20.9° and 68° degrees, and normal LSA values were found between 15° and 51° degrees [3]. It has been reported that when the thoracic kyphosis angle exceeds the normal value, musculoskeletal complaints such as postural affections, shoulder and cervical pain can affect all age groups [4], [5]. In the measurement of thoracic kyphosis, it has been stated that the evaluation of the muscular system as well as the skeletal system is an important aspect [6].…”

Sagittal plane deformity can be defined as a deviation from the normal curvature of the spine in the sagittal plane. This deformity can distort the natural shape of the spine and cause posture problems. In recent years, effects such as reduced activity in daily life, increased time spent in front of computers and mobile phones, and inactivity during the recent pandemic have also led to a significant increase in sagittal plane deformity. In this study, 16 healthy and 16 healthy adolescents with sagittal plane deformity participated. Surface EMG (sEMG) recordings were obtained from thoracal kyphosis and lumbar lordosis subjects, which are frequently seen in sagittal plane deformity (SPD) subjects, and healthy subjects. After filtering the raw sEMG data, wavelet packet transform analysis was performed. The energy values of the wavelet packets corresponding to the low and high frequency components have been calculated. Statistical analysis of the analysed data identified channels with significant differences between the two groups. The results showed that SPD subjects showed more muscle activity than healthy subjects and spent more energy to increase the quality of movements and to perform them with the correct muscle dynamics. It has been observed that SPD subjects develop compensations from different muscle regions in order to perform movements correctly due to postural changes. In healthy subjects, it was observed that movements were completed in accordance with the kinematics of the movement and that maximum movement quality was observed with less energy.
