The purpose of this case study was to identify the effects of posteroanterior (PA) mobilization on the cervical spine in a patient with chronic whiplash-associated disorder (WAD). The subject of this study was a 58-year-old woman who sustained a chronic WAD as a result of a motor vehicle accident two years prior. The subject has progressively worsening neck pain and stiffness. The subject was determined to have a grade IIb WAD the use of the Modified Quebec Classification. The intervention was central and unilateral PA mobilization on the spinous process of C4 and C5. The PA mobilizations were performed at the end of range to Maitland grade IV. The PA mobilization was conducted once daily for a total of eight days. Two sets of measurements were done one before and one after the intervention. Neck pain, cervical stiffness, range of motion and lordosis of the cervical spine were measured. Experimental intervention decreased the neck pain, and increased the neck stiffness and cervical ROM (range of motion) such as flexion, extension, lateral flexion and rotation. X-ray photographs also represented that cervical curvature increased from $35^{\circ}$ to $40^{\circ}$. This study suggested that PA cervical mobilization applied to hronic WAD is effective in decreasing pain, increasing cervical ROM and cervical curvature.

Purpose: Whiplash-associated disorder is often caused by external impact, such as a car accident, and it involves acceleration and deceleration of the flexion and extension of the neck. The purpose of this study is to determine whether the combination of cyrotherapy and a joint mobilization intervention in patients with acute whiplash-associated disorder is effective for pain, cervical range of motion (ROM), and muscle tone in the neck muscles. Methods: In this study, 20 patients with acute whiplash-associated disorder were randomly assigned to two groups. Group A was treated with cyrotherapy for 5 minutes, while group B was treated with cyrotherapy and a joint mobilization intervention. In both groups, visual analogue scale (VAS), neck disability index (NDI), cervical ROM, and muscle tone values were measured pre- and post-intervention. Results: According to the VAS values, both groups showed significant differences pre- and post-intervention (p<0.05), and in both groups, NDI was significantly decreased pre- and post-intervention (p<0.05). Finally, in terms of muscle tone, both groups showed significant changes before and after the intervention (p<0.05). Conclusion: These results showed that cryotherapy and joint mobilization can be effective interventions in patients with whiplash-associated disorder. In addition, to improve the ROM of the cervical joint and reduce NDI, the combination of cryotherapy and joint mobilization is considered more effective than the single intervention of cryotherapy.

The purpose of current study was to investigate the effects of the heights on the lower extremities, torso and neck segments for energy dissipation during single-leg drop landing from different heights. Twenty eight young healthy male subjects(age: $23.21{\pm}1.66yr$, height: $176.03{\pm}4.22cm$, weight: $68.93{\pm}5.36kg$) were participated in this study. The subjects performed the single-leg drop landing from the various height(30, 45 & 60 cm). Force plates and motion-capture system were used to capture ground reaction force and kinematics data, respectively. The results were as follows. First, the ROM at the ankle, knee, hip and trunk was increased with the increased heights but the ROM at the neck was increased in the 60cm. Second, the angular velocity, moment and eccentric work at the ankle, knee, hip, trunk, and neck was increased with the increased heights. Third, the contribution to total work at the knee joint was not significantly different, while the ankle joint rate was decreased and hip and neck rate was increased in the 60cm, and trunk rate was increased with the increased heights. Lastly, the increase in landing height was able to augment the level of energy dissipation not only at the lower extremities but also at the trunk and neck. The findings showed that drop landing affect trunk and neck with lower extremity joints. Therefore, we need to consider that trunk and neck strengthening including stability should be added to reduce sports injury during prevention training.

Background: Tension-type headaches, which make up the highest proportion of headaches, are prone to develop into chronic tension-type headaches (CTTH). The characteristic of CTTH in patients is that the active myofascial trigger point (ATrP) which causes pain in the muscles of the back of the head is increased, compared to the normal headache and moves the head position forward. Objective: The aim of this study was to investigate the effects of myofascial release (MFR) and posture correction in effectively improving neck function and sleep quality in the symptoms of CTTH patients. Design: Observer-blind study Methods: To reduce ATrP, MFR was applied and exercise was also applied to correct posture. The subjects of this study were 48 individuals randomly divided into three groups; The MFR group using the MFR technique; The MFR with exercise group subject to both the MFR technique and forward head position correction exercises (MFREx), and the control group. MFR and MFREx groups were given the relevant interventions twice a week for four consecutive weeks, and went through the number ATrPs, range of motion (ROM) of neck, Neck Disability Index (NDI) and the Pittsburgh Sleep Quality Index (PSQI) before and after the intervention. A physical therapist, who was fully familiar with the measuring methods of the equipment, was the measurer and not aware of the target's condition was blinded to take measurements only before and after intervention. Results: There was a significant improvement in the ATrP, Neck ROM, NDI and PSQI in the group of patients to whom the MFR technique and MFREx were applied. MFREx was more effective in increasing neck mobility. Conclusions: According to this study, the application of MFR is effective in improving neck movement and sleep quality in chronic tension headache patients.

Purpose: The aim of this study was to investigate and compare the risk factors focusing on the neck and lower back between general workers (GW) and mild intellectual disability workers (MIDW) in the automobile manufacturing industry. Methods: A total of 32 participants were required for this study design to achieve 80% power, 0.9 effect size, and an alpha level of 0.05. Each group consisted of 16 subjects, including GW and MIDW. Pain levels in the neck and lower back were measured for all participants using the visual analog scale (VAS). A dual digital inclinometer was used to measure the range of motion (ROM) in the neck and lower back three times, and the average was used for analysis. The independent t-test was used to compare between the wo groups. Cohen's d effect analysis was employed to determine the effect size. The significant level was set at 0.05. Results: In the MIDW, neck pain was significantly higher, and left cervical flexion was significantly decreased compared with the GW. There was no significant difference in lower back pain between the MIDW and GW. However, both lumbar flexion and extension, as well as lateral flexion, were significantly reduced in the MIDW compared with the GW. Conclusion: This study reveals that MIDW working in the automobile manufacturing industry have a greater risk of neck pain, limitation in left cervical flexion, and overall restriction in the ROM of the lower back compared with GW.

The Bethesda System for Reporting Thyroid Cytopathology (TBSRCT) is crucial for cytopathologists to use a standardized, category-based reporting system for thyroid fine needle aspirations and is effective for clear communication with the referring physicians. The new Bethesda System for Reporting Thyroid Cytopathology, the third edition in 2023, provides several key updates. The most important update is the assignment of only single name for each of the six diagnostic categories: (I) nondiagnostic; (II) benign; (III) atypia of undetermined significance; (IV) follicular neoplasm; (V) suspicious for malignancy; and (VI) malignant. An implied risk of malignancy (ROM) for each of six categories has been updated based on extensively published data since the second edition of TBSRTC in 2017 and offers both an average ROM for each category and the expected range of cancer risk. Estimated final ROM after excluding "Noninvasive Follicular Thyroid Neoplasm with Papillary Like Nuclear Features (NIFTP)" for each of six categories has been updated based on the reported mean decreases in the ROM if excluding NIFTP. For atypia of undetermined significance (AUS) category, the subcategorization is simplified and more formalized into 2 subgroups, AUS-nuclear atypia or AUS-other, based on the implied ROM and molecular profiling. For the pediatric thyroid disease, pediatric ROMs and management algorithms are newly added for the same six reporting categories for this age group. New or revised disease nomenclatures including high-grade follicular-derived carcinoma has been updated according to the recently published 2022 World Health Organization Classification of Thyroid Neoplasms. Brand new two chapters are added including clinical perspectives and imaging studies (Chap. 13) and the use of molecular and other ancillary tests (Chap. 14). The atlas is updated with new images to illustrate more effectively for new disease entity and diagnostic criteria.

Background: The purpose of this study was to investigate the effects of kinesio taping and neuromuscular rehabilitation exercise for patients with acute whiplash-associated disorders. Methods: Twenty acute whiplash-associated disorders patients were recruited for the study. Subjects were randomly allocated into two groups. Neuromuscular rehabilitation group (NRG) received neuromuscular rehabilitation exercise, kinesio taping group (KTG) received kinesio taping. All subject was evaluated before and after intervention by their range of motion (ROM), neck disability index (NDI), numeric pain rating scale (NPRS) and fatigability. Results: First, the ROM was significantly increased in all group (p<.05). The NDI, NPRS and fatigability were significantly decreased in all group (p<.05). Secondly, NRG had significantly more increased ROM (flexion, both rotation) than KTG (p<.05). NRG had significantly more decreased NDI, NPRS and fatigability than KTG (p<.05). Conclusion: According to the results above, increased in range of motion in the neck, decreased in NDI, NPRS, fatigability were more effective in the NRG that received neuromuscular rehabilitation exercise than the KTG that received kinesio taping.

Background: This study examined the effects of the muscle energy technique and cervical traction after applying conservative physical therapy in patients with cervical radiculopathy. Methods: Patients were randomly divided into two groups muscle energy technique (8 subjects) and cervical traction (8 subjects). Each group performed their exercise 70 minutes per day, three times week for four weeks. Pain intensity was measured with a visual analogue scale (VAS). Function was measured with the neck disability index (NDI). Cervical range of motion (ROM) was measured with a cervical range of motion (CROM) goniometer. Results: After four weeks of therapy, VAS (p<.05) and NDI (p<.05) significantly decreased, and ROM significantly increased in both groups (p<.05). There were also significant differences between the two groups for these three measures (p<.05). Conclusion: The muscle energy technique and cervical traction are more effective than cervical traction alone in reducing VAS and NDI and increasing ROM in patients with cervical radiculopathy.
