ABSTRACT
Context: Many standard books, literatures, and internet described the characteristic lineament of each salivary gland lesion. Nevertheless, there are dozens of disarray, confusion, and unmanageable morphological features regarding proper reporting. To fight with these issues, Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) was introduced in 2018, but still the third category, Atypia of undetermined significance (AUS), poses difficulties for the pathologists and clinicians for a definite interpretation. Aim: The aim is to analyze the risk of neoplasia (RON) and risk of malignancy (ROM) of Milan's category III (AUS) by subdividing into six groups based on cytolomorphology. Settings and Design: The duration of study was from March 2018 to may 2021 with the focus on ROM and RON of all Milan's categories with especial attention on AUS. Methods and Material: Result of total 329 Fine Needle Aspiration Cytology of salivary glands was categorized according to MSRSGC. On the basis of cytomorphology, further subtyping of AUS and its cytohistopathology correlation was done. The ROM and RON of each subtype was analyzed. Statistical Analysis: All data were calculated by existing formulas. Results: Out of 329 aspirates, 24 (07.29%) cases belong to AUS with availability of histology in 13 (54.17%) cases. RON and ROM was 84.62% and 53.85%, respectively. Cases of lymphocytes with nuclear atypia (L-NA) was the most prevalent (29.17%). The RON were 60.00%, 68.57,% 84.62%, 94.87%, 87.50%, 100%, 100% and the ROM were 20.00%, 11.42%, 53.85%, 05.13%, 43.75%, 83.33% and 100% in each Milan's categories I, II, III, IVa, IVb, V, and VI, respectively. ROM was the highest in cystic fluid with nuclear atypia (C-NA) (100.0%), followed by basaloid cells (75%), L-NA (66.675), and SC (50%), but ROM was zero in NA and oncocytic cells. Conclusions: Subgrouping of AUS helps to dissipate the muddiness and provide more exact and reproducible diagnostic and prognostic tool.
ABSTRACT
Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) rehabilitation training on functional recovery of athletic rotator cuff injury. Methods Twenty-two college students with athletic rotator cuff injuries were stratified according to their gender and randomly divided into resistance band + passive joint range of motion (ROM) training group (control group) and PNF training group (experimental group). The visual analog scale (VAS) was used to evaluate subjective pain intensity of the shoulder joint. Pain positive rate for each manipulation test of rotator cuff injury was observed, and active ROM and muscle strength of the shoulder joint were measured. Improved UCLA shoulder joint score was used to evaluate comprehensive function of the shoulder joint. Results After training, VAS scores and pain positive rate in two groups were lower than those before training, and VAS scores and pain positive rate in experimental group were lower than those in control group. Muscle strength, active ROM in all directions and improved UCLA score of the shoulder joint in two groups were also higher than those before training, and the internal rotation muscle strength, the internal rotation and external rotation active ROM, improved UCLA score of the shoulder joint in experimental group were higher than those in control group. Conclusions PNF rehabilitation training can reduce the pain of athletic rotator cuff injury, improve the active ROM, muscle strength and UCLA shoulder joint score. The function recovery effect of PNF training is better than that of resistance band + passive ROM training.
ABSTRACT
Objective To evaluate the influence of dynamic fixation (rotating and sliding pedicle screws) on stability of the atlantoaxial joint. Methods A series of in vitro biomechanical tests were performed using six fresh adult cervical spines (occipital bone-C4 segment) to simulate different conditions in surgery， including the intact state, the injury state, rigid fixation, rotating pedicle screw fixation, sliding pedicle screw fixation. The repeated measurement design was employed, and under intact, injury and different fixation states, the pure moment of 1.5 N·m in flexion-extension, left-right lateral bending, left-right axial rotation directions were applied using the spinal testing machine. The movement of atlantoaxial spine was measured consecutively by three-dimensional （3D） measurement system in order to analyze the range of motion (ROM) and neutral zone (NZ) of atlantoaxial joints. Results Under injury state, ROM of atlantoaxial joints was significantly larger than that under intact state during flexion, extension, lateral bending and rotation, leading to the instability of atlantoaxial joints. ROM of fixation segments was significantly reduced during flexion, extension, lateral bending and rotation after rigid and dynamic fixation. Compared with rigid fixation, dynamic fixation showed a significant ROM increase during lateral bending. NZs of fixation segments after dynamic fixation were significantly reduced. There were no significant ROM differences between rigid fixation and dynamic fixation. Conclusions The stability of atlantoaxial joints by dynamic fixation during flexion, extension and rotation was comparable to that by rigid fixation, but weaker during lateral bending. Dynamic screw fixation can maintain the relative stability of atlantoaxial joints.
ABSTRACT
Flexibility is an important factor of physical fitness to prevent sports injuries. However, the best timing to improve flexibility during the growth and development period in children has been unclear. To compare the acute effects of static stretching on flexibility between school-grade children in the growth and development period, we measured the hip joint flexion range of motion (RoM) by using straight leg raising (SLR) before and after static stretching (6 exercises, 15 seconds, 2 sets) in 50 young male children aged 7 to 13 years (the second grade of elementary school to the first grade of junior high school). The RoM in SLR significantly increased after stretching versus that before stretching in all subjects. This positive improvement of RoM was statistically significant among all grade levels. Notably, the change rate in RoM after stretching was significantly greater in the fourth grade of elementary school than in the other grades. The rate of height increase during the past year was lower in students from the fourth grade than in students from the second grade of elementary and the first grade of junior high school. These results suggest that flexibility training is more effective during the slow-down period of growth and development in young male children.
ABSTRACT
Objective：The Japanese Orthopaedic Association Low Back Pain Evaluation Questionnaire (JOABPEQ) consists of 25 questions, which allows for the multifaceted evaluation of patients with low back pain. In this study, we aimed to investigate whether the JOABPEQ could be used to construct a regression model to quantify low back pain, lower limb symptoms, and hip range of motion (ROM) in patients with lumbar spinal stenosis.Methods：We evaluated 115 patients with lumbar spinal stenosis scheduled to undergo surgery at our hospital. We measured the degrees of low back pain, lower leg pain, and lower leg numbness using the visual analog scale before the surgery. In addition, we measured the ROM of the hip joint during flexion, external rotation, and internal rotation. All responses of the JOABPEQ and physical function data were subjected to a partial least-squares (PLS) regression analysis.Results：Low back pain, lower limb pain, lower limb numbness, and hip ROM during flexion could each be used for significant regression models with JOABPEQ items. However, the hip ROMs during external and internal rotation could not be used for regression models with the JOABPEQ.Conclusion：On the basis of the results of the PLS regression analysis in this study, the degree of pain symptoms in patients with lumbar spinal stenosis may be quantified with the JOABPEQ items. Furthermore, the flexion angle of the hip ROM was quantified using the JOABPEQ items. The results of this study may indicate an effective means for establishing treatment plans for physical therapy.
ABSTRACT
Background: Neuromuscular electrical stimulation (NMES) has been noted as an effective pre-conditioning intervention for an increase of the rate of development (RFD). However, it is unknown whether NMES increases muscle flexibility. Therefore, the purpose of this study was to investigate whether neuromuscular electrical stimulation (NMES) at 20% of maximal voluntary isometric contraction (MVIC) torque level for 5 seconds used as a warm-up is effective for improving the range of motion (ROM) following increased tolerance for muscle extensibility with/without alteration of the MTU stiffness. Methods and Results: Maximum ROM and ROM with standardized torque (30N) were measured in both legs in thirteen healthy males before and after NMES intervention at a 20% MVIC level for 5 seconds. The maximum ROM increased after intervention compared with before intervention on the NMES side, while it was not changed on the non-NMES side. In addition, there were no significant differences in the ROM with standardized torque in any measurements. Conclusion: It is concluded that NMES at 20% MVIC for 5 seconds could be effective for improving ROM following an increased tolerance for muscle extensibility without alteration of the MTU stiffness.

ABSTRACT
Background: Serious, major meniscal fractures are the most common knee injuries. In the management of meniscal tears, physical therapy has shown positive results, and additional medication is required to reduce the effects of meniscal tears. This study aimed to evaluate the feasibility of the mulligan squeeze procedure in combination with conventional pain relief therapy and to increase the range of movement and functional ability of meniscal tear patients. The study aims at reviving pain, increasing ROM and stability, and improving the quality of their lives. Methods: In this randomized controlled trial, 40 patients were chosen and randomly assigned to two groups, A and B, clinically diagnosed with a meniscal tear. The Numeric Pain Rating Scale (NPRS), the Patient-Specific Functional Scale (PSFS), and knee range of motion were reported to determine the pain level and functional capability of the patients. Results: During the 4th and 6th week, all classes showed a significant gap (P<0.05). At the end of the 6th week, the standard variance and the overall analysis team t-test values were higher than the control group. Conclusion: The two teams showed significant progress for NRPS, ROM, and PSFS, but the experimental group showed more significant improvement in all the parameters.
ABSTRACT
BACKGROUND: The ROM technique has been widely used to determine the rotational alignment of tibial prosthesis in total knee arthroplasty, but the accuracy of this technique remains controversial. However, there is no report on the influencing factors of ROM technique. OBJECTIVE: To explore the influencing factors of ROM technique in determining the rotational alignment of tibial prosthesis in total knee arthroplasty. METHODS: Totally 61 patients underwent unilateral knee arthroplasty, including 18 males and 43 females, aged between 55 and 78 years. All patients were diagnosed as knee osteoarthritis before operation. All operations were performed with the posterior cruciate-stabilizing total knee prostheses. All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. The rotational orientation of the tibial prosthesis was determined by the ROM technique with closed and unclosed medial retinaculum. A line from the center of the posterior cruciate ligament to the medial border of the patellar tendon was used as the anteroposterior axis of tibia (Akagi line). The angles between the anteroposterior axis of tibia and lines determined by the ROM technique were measured to identify the classification of patellar track so as to decide whether the classification of patellar track, closing and unclosing medial retinaculum are the influencing factors of ROM technology. RESULTS AND CONCLUSION: (1) The angles between the Akagi line and lines determined by the ROM technique respectively were (0.5±2.5)°, (-0.9±2.6)°, and (-3.9±3.4)° for the unclosed medial retinaculum and (0.6±2.3)°, (-0.3±2.2)°, and (-1.5±2.9)° for the closed medial retinaculum. (2) For type III patellar track, the angle between line determined by the ROM and Akagi line was significantly internal rotation compared with type I and type II patellar track (P 0.05). For type III patellar track, closing the medial retinaculum could significantly reduce the difference between Akagi line and the line determined by ROM technology (P < 0.05). (4) These results indicate that for type I and type II patellar track, ROM technique can accurately locate the rotational alignment of tibial prosthesis in total knee arthroplasty, and closing or unclosing the medial retinaculum will not affect the accuracy of the results. As to type III patellar track, whether or not the medial retinaculum is closed may lead to failure in determining the rotation alignment of the tibial prosthesis.
ABSTRACT
OBJECTIVE@#To observe the effect of electroacupuncture (EA) on the rehabilitation of knee joint function after anterior cruciate ligament (ACL) reconstruction.@*METHODS@#A total of 140 patients with ACL reconstruction were randomly divided into an observation group (58 cases recruited, 12 cases dropped out) and a control group (65 cases recruited, 5 cases dropped out). The patients in the control group were treated with routine rehabilitation treatment. The patients in the observation group, on the basis of the treatment in the control group, were treated with EA at Fengshi (GB 31), Futu (ST 32), Zusanli (ST 36), Shangjuxu (ST 37), Fenglong (ST 40), Xuanzhong (GB 39), Diji (SP 8) and Sanyinjiao (SP 6) on the affected side (2 Hz/100 Hz of dilatational wave, 2-5 mA). Each EA treatment lasted 20-30 min, twice a day for 7 days. The swelling degree (d), pain visual analogue scale (VAS), knee joint range of motion (ROM), scores of International Knee Documentation Committee (IKDC) subjective short form and scores of Lysholm were observed in the two groups 1 day, 1 month, 3 months, 6 months and 1 year after operation.@*RESULTS@#One month and 3 months after operation, the swelling degree (d) and VAS scores in the observation group were lower than those in the control group (0.05). One month, 3 months, 6 months and 1 year after operation, the ROM of the knee joint in the observation group was higher than that in the control group (<0.05), the IKDC score and Lysholm score were higher than those in the control group (<0.05). Within one year, there were no relaxations, fractures and other related complications in the two groups. The pivot shift test, anterior drawer test and the Lachman test were all negative.@*CONCLUSION@#EA combined with routine rehabilitation training could obviously reduce the pain of knee joint, improve the swelling degree, increase the ROM of knee joint, promote the functional recovery in patients with ACL reconstruction, which are superior to rehabilitation training alone.
ABSTRACT
Background: Neck pain is one of the main causes of those who use video display terminal devices. Prolonged period of work in an awkward posture would mainly lead to neck pain among the VDT users. Studies show the prevalence of neck pain among VDT users as 45.5%. It is essential to identify factors for preventing people from getting neck pain. Studies show that musculoskeletal disorders are related to physical fitness level. Many factors in physical fitness can predict the incident of musculoskeletal disorders. There are still studies which are specific to neck pain and physical fitness in office workers. The context and purpose of the study: The main aim of the study is to compare the flexibility, strength, endurance and proprioception of neck among the VDT users in college students with neck pain and without neck pain. Results: The main finding of this study was that the video display terminal device users who use more than 4 hours / day have significantly lower flexibility, endurance and proprioception among student with neck pain compared to without pain VDT devices students. But there is no significant difference in strength among both groups. Conclusion: The majority of VDT user’s students who have neck pain are more affected in range of motion, endurance and proprioception compare to without neck pain. But there is no significant difference in strength among both groups. Implication: static posture without taking break in student who use VDT devices can be decrease in physical fitness of neck, so student are take break in between time to time and stretch their leg as well as arm ,neck.
ABSTRACT
In the present research study 4 shoulder muscles-the supraspinatus, infraspinatus, the middle deltoid and the upper part of the trapezius-were assessed for muscle thickness using real time ultrasonography (RUSI) in various degrees of abducted and flexed arm positions, in 30 patients with acute and sub-acute shoulder pain and 30 asymptomatic healthy subjects (N=60). The symptomatic and asymptomatic subjects were further subdivided according to affection of dominant (n=15) and non-dominant (n=15) shoulder joint. Muscle thickness (mm) was measured using real time ultrasonography of dominant and non-dominant shoulder in different range of movement of shoulder abduction and flexion in symptomatic patients and asymptomatic subjects with and without gripping action on the dynamometer. The subjects were asked to produce a static handgrip force of in 8 different arm positions. In all positions, the subjects held a dynamometer in the hand. The activity in the shoulder muscles was assessed using RUSI while the participating subjects produced a handgrip with maximal force. Muscle thickness and changes with activity was similar in symptomatic and asymptomatic individuals. Muscle activity increased in the middle deltoid muscle in humeral flexion and abduction from 0 0 through 800, whereas supraspinatus and lower trapezius showed increased muscle thickness only in the initial ranges of movement of shoulder flexion, whereas, infraspinatus did not show exhibit any significant change. Our findings imply that high static hand grip force, particularly in elevated arm positions, increases the load on some shoulder muscles, independent of presence of pain in the shoulder. Handgrip activity is important to evaluate while assessing shoulder load in manual work and in clinical evaluations of patients with shoulder pain. Also, while rehabilitation it would be possible to make use of hand gripping activity and load the shoulder muscles differently and distinctly throughout the ranges of movement of shoulder joint.

ABSTRACT
Objective To analyze the influence of ligaments surrounding sacroiliac joints (SIJs) on stability of SIJs by finite element method. Methods The finite element lumbar spine-pelvis-femur model was established. Based on this normal model, all SIJ ligaments in both sides were removed in turn, to establish models without iliolumbar ligaments, sacroiliac anterior ligaments, sacroiliac posterior ligament, sacrotuberous ligaments, sacrospinous ligaments, sacroiliac interosseous ligaments, respectively. The models were used to simulate physiological motions of the spine. The range of motion (ROM) and average stress on the left and right SIJs were analyzed and compared with the normal models. Results Compared with the normal SIJ model, no significant differences in the ROM of bilateral SIJs were found in the models without sacrotuberous ligaments, sacrospinous ligaments and sacroiliac posterior ligaments; for the model without acroiliacinterosseous ligaments, there was no significant difference in the ROM of the left SIJs under spinal right rotation and ROM of the right SIJs under spinal extension, but the ROM of bilateral SIJs increased significantly under the other spinal physiological activities. Under the physiological activities of the spine, the average stress of the SIJ surface in the left and right sides of the model without acroiliacinterosseous ligaments significantly decreased. Conclusions Of all the sacroiliac ligaments, the sacroiliac interosseous ligaments showed the maximum influences on the stability of SIJs. The research findings are helpful to investigate the mechanism of SIJ subluxation and provide certain theoretical basis for clinical treatment of SIJ subluxation.
