Clinical Outcomes of Arthroscopic Adhesiolysis: A Case Series of 40 Patients With Postoperative Knee Stiffness.

Introduction Restricted range of motion over the knee joint is a known complication following the surgical procedure. Aggressive rehabilitation protocols can initially manage knee stiffness due to arthrofibrosis. If conservative management fails, surgical (open or arthroscopic) release is the preferred modality of management. We present a series of 40 patients with postoperative knee stiffness who were treated with arthroscopic adhesiolysis. Material and methods This is a retrospective study conducted at Phoenix Orthopedic Superspeciality Hospital, Nagpur, India, from 2017 to 2021. Our study included 40 patients with postoperative knee joint stiffness, of whom 27 were males and 13 were females. The study considered the duration of stiffness, which ranged from six months to five years. All patients underwent arthroscopic knee release. A rigorously supervised physical therapy program followed this procedure. Patients were examined at three months, six months, and one year to assess improvement in knee range of movement. Results Out of 40 patients, six were classified as Shelbourne type 4, and the remaining were Shelbourne type 3. Twenty-three of 40 patients developed arthrofibrosis following intra-articular or peri-articular fracture fixation surgery; 11 patients were operated on arthroscopically for anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) reconstruction. Three patients developed stiffness following total knee replacement, one following patellectomy, and three following infection after fracture fixation. The mean pre-op knee range of motion (ROM) was 48.875 degrees. Following arthroscopic release, the mean improvement in ROM was 60 degrees intra-operatively. The average postoperative range was 108.25 degrees. Conclusion Arthroscopic adhesiolysis and quadriceps release are reliable methods for dealing with postoperative knee stiffness. It prevents wound complications and increases the chances of surgical site infection due to smaller incisions. Postoperatively, we achieved an average increase of 60 degrees in ROM over the knee joint.

Publicly Available Anatomic Total Shoulder Arthroplasty Rehabilitation Protocols Show High Variability and Frequent Divergence from the 2020 ASSET Recommendations.

Background: In 2020, the American Society of Shoulder and Elbow Therapists (ASSET) published an evidence-based consensus statement outlining postoperative rehabilitation guidelines following anatomic total shoulder arthroplasty (TSA). Purpose: The purpose of this study was to (1) quantify the variability in online anatomic TSA rehabilitation protocols, and (2) assess their congruence with the ASSET consensus guidelines. Methods: This study was a cross-sectional investigation of publicly available, online rehabilitation protocols for anatomic TSA. A web-based search was conducted in April 2022 of publicly available rehabilitation protocols for TSA. Each collected protocol was independently reviewed by two authors to identify recommendations regarding immobilization, initiation, and progression of passive (PROM) and active range of motion (AROM), as well as the initiation and progression of strengthening and post-operative exercises and activities. The time to initiation of various components of rehabilitation was recorded as the time at which the activity or motion threshold was permitted by the protocol. Comparisons between ASSET start dates and mean start dates from included protocols were performed. Results: Of the 191 academic institutions included, 46 (24.08%) had publicly available protocols online, and a total of 91 unique protocols were included in the final analysis. There were large variations seen among included protocols for the duration and type of immobilization post-operatively, as well as for the initiation of early stretching, PROM, AROM, resistance exercises, and return to sport. Of the 37 recommendations reported by both the ASSET and included protocols, 31 (83.78%) were found to be significantly different between groups (p\<0.05). Conclusion: Considerable variability was found among online post-operative protocols for TSA with substantial deviation from the ASSET guidelines. These findings highlight the lack of standardization in rehabilitation protocols following anatomic TSA. Level of Evidence: 3b.

Mobility and anthropometry of the sacroiliac joint: range of motion and morphological characteristics.

Purpose: The sacroiliac joint (SIJ), a synovial joint with irregular surfaces, is crucial for stabilizing the body and facilitating daily activities. However, recent studies have reported that 15-30% of lower back pain can be attributed to instability in the SIJ, a condition collectively referred to as sacroiliac joint dysfunction (SIJD). The aim of this study is to investigate how the morphological characteristics of the auricular surface may influence the SIJ range of motion (ROM) and to examine differences in SIJ ROM between females and males, thereby contributing to the enhancement of SIJD diagnosis and treatment. Methods: We measured SIJ ROM using motion-analysis cameras in 24 fresh cadavers of Korean adults (13 males and 11 females). Using three-dimensional renderings of the measured auricular surface, we investigated the correlations between the morphological characteristics of the auricular surface and the ROM of the SIJ. Results: The SIJ ROM was between 0.2° and 6.7° and was significantly greater in females (3.58° ± 1.49) compared with males (1.38° ± 1.00). Dividing the participants into high-motion (3.87° ± 1.19) and low-motion (1.13° ± 0.62) groups based on the mean ROM (2.39°) showed no significant differences in any measurements. Additionally, bone defects around the SIJ were identified using computed tomography of the high-motion group. In the low-motion group, calcification between auricular surfaces and bone bridges was observed. Conclusion: This suggests that the SIJ ROM is influenced more by the anatomical structures around the SIJ than by the morphological characteristics of the auricular surface.

Exploring the impact of rehabilitation on post-surgical recovery in elbow fracture patients: a cohort study.

INTRODUCTION: Elbow fractures, characterized by their complexity, present significant challenges in post-surgical recovery, with rehabilitation playing a critical role in functional outcomes. This study explores the efficacy of rehabilitative interventions in enhancing joint range of motion (ROM) and reducing complications following surgery for both stable and unstable elbow fractures. METHODS: A cohort of 15 patients, divided based on the stability of their elbow fractures and whether they received post-operative rehabilitation, was analyzed retrospectively. Measurements of ROM-including flexion, extension, pronation, and supination-were taken at three follow-ups: 15-, 30-, and 45-day post surgery. The study assessed the impact of rehabilitation on ROM recovery and the resolution of post-surgical complications. RESULTS: The findings indicated no statistically significant differences in ROM improvements between patients who underwent rehabilitation and those who did not, across all types of movements measured. However, early rehabilitative care was observed to potentially aid in the mitigation of complications such as joint stiffness, especially in patients with stable fractures. CONCLUSION: While rehabilitation did not universally improve ROM recovery in elbow fracture patients, it showed potential in addressing post-operative complications. The study underscores the importance of individualized rehabilitation plans and highlights the need for further research to establish evidence-based guidelines for post-surgical care in elbow fractures.

Postoperative Continuous Passive Motion Does Not Improve the Range of Movement Achieved After Manipulation Under Anesthetic for Stiffness in Total Knee Replacement.

Background: Stiffness is a common complication following total knee arthroplasty. Manipulation under anesthesia (MUA) is an intervention that can potentially improve range of motion (ROM). Continuous passive motion (CPM) therapy has been utilized to enhance post-MUA ROM, but its effectiveness remains debated. This study assesses whether CPM therapy after MUA results in superior ROM outcomes compared to MUA alone. Methods: A retrospective analysis included patients undergoing MUA for stiff primary total knee arthroplasty between 2017 and 2022. Demographics and ROM data were collected. Patients were in 2 groups: those who received inpatient CPM post-MUA and those who received day-case MUA alone. Complications and further interventions were noted. Results: Of 126 patients, 39 underwent MUA only (day-case group), and 87 received CPM and MUA (inpatient group). Mean preoperative ROM was 69.4° (standard deviation [SD]:18.0°) and 73.9° (SD: 18.1°) for inpatient and day-case groups, respectively. Mean post-MUA ROM improved by 39.4° (SD: 17.7°) and 25.5° (SD: 11.1°) inpatient groups and day-case, respectively. The mean percentage of ROM gained at MUA maintained at final follow-up was 63.7% (40.8%) and 67.0% (47.5%) inpatient and day-case groups, respectively. Conclusions: This study found no advantage in the routine use of CPM post-MUA for stiff total knee replacement patients, suggesting it may not provide sustained ROM improvements compared to MUA alone. Cost-effectiveness and patient selection merit further investigation.

Cervical Alignment and Range of Motion Change after Anterior 3-Level Hybrid Surgery Compared with Cervical Laminoplasty: A Matched Cohort Study.

OBJECTIVES: Cervical alignment and range of motion (ROM) changes after cervical spine surgery are related to cervical biomechanical and functions. Few studies compared these parameters between posterior laminoplasty and anterior 3-level hybrid surgery incorporating anterior cervical discectomy and fusion (ACDF) with cervical disc replacement (CDR). This study is aimed to detect the differences of cervical alignment and ROM changes of the two surgeries in a matched-cohort study. METHODS: From January 2018 and May 2020, 51 patients who underwent 3-level hybrid surgery incorporating ACDF with ACDR were included. A 1:1 match of the patients who underwent cervical laminoplasty based on age, gender, duration of symptoms, body mass index, and cervical alignment type was utilized as control group. General data (operative time, blood loss, etc.), Japanese Orthopaedic Association (JOA) score, VAS (Visual Analog Score), NDI (The Neck Disability Index), cervical sagittal alignment, and cervical range of motion (ROM) were recorded and compared. RESULTS: Both groups gained significant improvement in JOA, VAS, NDI scores postoperatively (p < 0.05). Cervical alignment significantly increased in hybrid group and decreased in control group after surgeries (p < 0.001). ROM decrease was similar in two groups. For cervical lordosis, though cervical alignment angle in control group decreased, the final follow-up cervical alignment and cervical alignment changes were not significantly different between hybrid and control groups. For cervical non-lordosis, cervical alignment decreased in control group while increased in hybrid group. At final follow-up, cervical alignment and the changes between the two groups were significantly different. Both control group and hybrid group had similar ROM decrease after the surgery no matter whether there was cervical lordosis or non-lordosis. Hybrid surgery showed cervical alignments significantly improved and similar ROM preservation compared with control group at final follow-up both for 1-level and 2-level disc replacement subgroups. CONCLUSIONS: The hybrid surgery demonstrated advantages of preserving cervical alignment and gaining similar cervical ROM preservation compared with cervical laminoplasty, especially for cervical non-lordosis. Given the importance of restoring lordotic cervical alignment, hybrid surgery may be preferred over laminoplasty to treat multilevel cervical disc herniation.

Shoulder function following oncoplastic breast conserving surgery-a narrative review.

Background and Objective: The high prevalence of breast cancer survivors makes it very relevant to investigate late morbidity following the treatment. Oncoplastic breast conserving surgery (OPS) has gained great popularity over the past years, and evidence-based knowledge suggest better prognosis for treatment with breast conserving surgery (BCS) compared to mastectomy. The aim was to investigate if OPS causes late effects on an acceptable level compared to what we know about breast surgery causing late effects. Methods: Using the Medical Subject Headings (MeSH) terms "Breast Neoplasms", "shoulder", "oncoplast*", and "reconstruct*", the databases PubMed, Embase, and Scopus were searched on the 6th of June 2023. The literature search was managed in Covidence. We focused on studies describing late effects especially shoulder function including restrictions in mobility, reduced strength, as well as functional impairment. Key Content and Findings: Nine studies fulfilled the inclusion criteria. Different kinds of oncoplastic procedures were described-most of them described volume replacement procedures. The knowledge of shoulder morbidity following OPS is limited. The heterogeneity in the selected studies was broad. Some of the studies were small and there was a considerable variation in follow-up time. They described shoulder function based on several different evaluation methods [range of motion (ROM), Disabilities of the Arm, Shoulder, and Hand (DASH), Quick-DASH (Q-DASH), Shoulder Pain and Disability Index (SPADI), health-related quality of life (HRQoL), and non-validated subjective questionnaires]. All studies found acceptable levels of shoulder morbidity. Conclusions: The requisite knowledge of late effects following OPS is still not available for unambiguous recommendations. This narrative review has elucidated the knowledge and has reached a conclusion based on review of the existing literature of this item. We found that the risk of decreased shoulder function caused by OPS-volume displacement as well as volume replacement-does not exceed the risk of shoulder problems seen after BCS and mastectomy with or without immediate reconstruction. Therefore, OPS can be considered if conventional BCS is not possible. But the knowledge of shoulder function after OPS is limited, and studies comparing shoulder function after OPS, BCS and mastectomy with or without immediate reconstruction are warranted.

Splitting the subscapularis at the upper two-third and lower one-third junction or in the middle during the Latarjet-Walch procedure does not affect the external rotation range of motion.

BACKGROUND: Our purpose was to investigate (1) the difference in external rotation range of motion (ROM) limitation between the two recommended subscapularis-splitting techniques (mid-split versus upper 2/3rd -lower 1/3rd split) and (2) the differences in elevation ROM, internal rotation ROM, the functional outcomes and the internal rotation strength between the two techniques in the Latarjet-Walch procedure. MATERIAL AND METHODS: We conducted a prospective cohort study of patients with recurrent shoulder instability treated by the Latarjet-Walch procedure between January 2021 and January 2022. After a priori calculation of sample size, 32 patients were divided into two groups according to the type of intraoperative subscapularis split [upper 2/3rd -lower 1/3rd level split (LS group, n=19) versus mid-level split (MS group, n=13)] performed in the Latarjet-Walch procedure. RESULTS: The final ER1 (external rotation with the arm adducted) deficit (as compared to opposite normal shoulder) was not significantly different between the LS (9° ± 8°) and the MS (10° ± 8°, p=0.8) groups. The final ER2 (external rotation with the elbow abducted @ 90°) deficit was not significantly different between that of the LS (14° ± 12°) and the MS groups (12° ± 9°, p=0.5). Only in the MS group were the final ER1 deficit (p=0.03) and the final ER2 deficits (p=0.05) significantly better (smaller) than the corresponding baseline values. The Rowe scores (p=0.2) and the shoulder subjective value (p=0.7) were not significantly different between the two groups. There were no postoperative subluxations in either group. However, 3 patients tested positive in apprehension testing in the LS group compared to none in the MS group, the difference being statistically insignificant. The internal rotation strength was 95% of the normal, unaffected shoulder in the LS group and 93% of the normal in the MS group (p=0.6). Computed tomography (CT) scan evaluation showed that the transverse diameter index of subscapularis (upper subscapularis diameter / lower subscapularis diameter) was not different in the MS (0.9 ± 0.1) and the LS (0.9 ± 0.1, p=0.3) groups. CONCLUSION: We found no difference in final external rotation limitation between the upper 2/3rd - lower 1/3rd versus mid-level subscapularis split techniques. The functional outcomes, the internal rotation strength, subscapularis transverse diameter index, and fatty infiltration in the CT scan were similar in both groups.

The effect of mulligan mobilization technique application in addition to conventional physiotherapy on pain and joint range of motion in people with neck pain.

BACKGROUND: To evaluate the effect of the Mulligan mobilization technique on pain intensity and range of motion in individuals with neck pain. METHODS: Forty individuals with mechanical neck pain were enrolled in the study. The patients were randomly divided into 2 groups and a total of 10 sessions of treatment were administered to all 2 groups for 2 weeks, 5 days a week. Mulligan mobilization technique, electrophysical agents, active range of motion, and stretching exercises were carried out in the Mulligan group. In contrast, only electrophysical agents and exercises were applied to the conventional physiotherapy group. Range of motion (ROM) of the neck, Visual Analog Scale (VAS), Neck Pain and Disability Scale (NPDS), and Short-Form 36 Health Survey (SF-36) were used for evaluation. RESULTS: Statistical analyses were done to compare the amounts at the baseline and immediately after treatment. Statistically significant improvements were found in the post-treatment ROM, VAS, NPDS values in both groups (p < 0.05). When the differences were compared, the results of the Mulligan group were significantly better than the conventional physiotherapy group (p < 0.05). There was no significant difference between the groups in terms of SF-36 parameters (p > 0.05). CONCLUSIONS: This study showed that the Mulligan mobilization technique plus conventional physiotherapy is more effective than conventional physiotherapy in increasing joint range of motion, reducing pain, and reducing neck disability. TRIAL REGISTRATON: ClinicalTrials.gov (NCT05074576).

Risk of malignancy and overall survival associated with the diagnostic categories in the World Health Organization Reporting System for Pancreaticobiliary Cytopathology.

BACKGROUND: The World Health Organization (WHO) classification system revised the Papanicolaou Society of Cytopathology (PSC) system for reporting pancreaticobiliary cytopathology. To better stratify intraductal and/or cystic neoplasms by cytologic grade, the neoplastic, other category was replaced by two new categories: pancreaticobiliary neoplasm, low-risk/grade (PaN-Low) and pancreaticobiliary neoplasm, high-risk/grade (PaN-High). Low-grade malignancies were placed in the malignant category, and benign neoplasms were placed in the benign/negative for malignancy category. METHODS: An institutional pathology database search identified patients who underwent endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic lesions from January 2015 to April 2022. The absolute risk of malignancy (ROM) was determined by histologic and/or clinical follow-up of at least 6 months, and overall survival rates were calculated across diagnostic categories, comparing the WHO and PSC systems. RESULTS: In total, 1012 cases were reviewed and recategorized. The ROM for the WHO system was 8.3% for insufficient/inadequate/nondiagnostic, 3.2% for benign/negative for malignancy, 24.6% for atypical, 9.1% for PaN-Low, 46.7% for PaN-High, 75% for suspicious for malignancy, and 100% for malignant. Comparatively, the ROM for the PSC system was 7.4% for nondiagnostic, 3.0% for negative for malignancy, 23.1% for atypical, 0% for neoplastic, benign, 7.3% for neoplastic, other, 75% for suspicious for malignancy, and 100% for malignant. The WHO system demonstrated superior stratification for overall survival. CONCLUSIONS: The WHO system significantly improves the stratification of ROM and overall survival across diagnostic categories by introducing the PaN-Low and PaN-High categories and reassigning low-grade malignancies to the malignant category. Analyzing EUS-FNA samples with the WHO system provides critical insights for guiding clinical management.

Functional outcomes and quality of life in patients who undergone conventional or endoscopic/robotic retroauricular neck dissection: a case-control study.

Background: Neck dissection performed via retroauricular approach emerged as an alternative to the conventional approach, aiming to maintain therapeutic efficacy with lower postoperative morbidity. Differences among these modalities in terms of functional aspects and quality of life (QOL) remains unclear. This study aims to evaluate the anatomical and functional aspects and the QOL in patients undergoing unilateral neck dissection via conventional or retroauricular (endoscopic or robotic) access. Methods: This study involved consecutively 35 patients who underwent unilateral neck dissection for head and neck cancer, 25 submitted to the conventional surgery [conventional group (CG)] and 10 to the retroauricular approach [retroauricular group (RG)]. Patients were evaluated preoperatively and on the 30th postoperative day (POD) regarding range of motion (ROM) of the cervical spine and shoulder, trapezius muscle strength and QOL. Results: The CG and RG were similar in terms of anthropometric, clinical and surgical variables. The mean age of both groups was between 52 and 55 years old. There was a predominance of females in the CG (52%) and males in the RG (70%); P=0.08. The most affected site was the oropharynx followed by the thyroid in the two groups and the most frequently dissected levels were I-III in both groups. There was a difference in the length of hospital stay {CG: 5 [1-22] days and RG: 2 [1-6] days; P=0.02} and pain scores at the 30th POD was higher in CG group (P=0.002). Regarding the cervical spine ROM, it was better in RG in the 30th POD for neck extension, ipsilateral lateroflexion, contralateral lateroflexion and contralateral rotation (P<0.05). No significant differences were found regarding shoulder ROM. Trapezius muscle strength, was also higher at the 30th POD in RG group (P<0.05). QOL was most impacted in the CG in the Chewing and Shoulder domains and Physical Function dimension at the 30th POD (P<0.05). Conclusions: Postoperative functional morbidity was lower in patients undergoing retroauricular neck dissection. The cervical spine ROM and trapezius muscle strength were better in patients undergoing retroauricular approach and postoperative QOL was worse in patients undergoing conventional neck dissection.

The Validity and Reliability of a Smartphone Application for Measuring Wrist and Metacarpophalangeal Joint Motion.

Background Accurate measurement of the range of motion (ROM) is crucial for guiding upper extremity rehabilitation. Inaccurate measurements can mislead clinicians and harm patient compliance. This study aimed to evaluate the validity and reliability of a smartphone application (Angulus) for measuring wrist and metacarpophalangeal (MCP) joint ROM. Methodology This study included 64 volunteers with no prior wrist injuries. The wrist flexion/extension, radial/ulnar deviation, and MCP joint flexion/extension ROM were assessed by an experienced physiotherapist (Assessor 1) using the Angulus and a standard two-arm goniometer. The validity of Angulus was evaluated by correlating it with the goniometer measurements using the Pearson correlation coefficient. For the reliability analysis, an inexperienced biomedical engineer (Assessor 2) performed the same measurements using Angulus twice in different sessions, in addition to Assessor 1. The intra-rater and inter-rater reliability were tested using the intraclass correlation coefficient. Results The mean age of the participants was 29.5 ± 8.2 years, with 62% being female. The validity of the Angulus app measurements was indicated by the adequate to excellent correlation between the Angulus and goniometer measurements (ranging from 0.44 to 0.81). The intra-rater reliability of the Angulus app was excellent for Assessor 1 (ranging from 0.76 to 0.90) and adequate to excellent for Assessor 2 (ranging from 0.71 to 0.88). The inter-rater reliability of Angulus was excellent (ranging from 0.91 to 0.96). Conclusions Angulus is a valid and reliable method to measure the wrist and MCP joint ROM.

Role of Ancillary Techniques in Reporting Serous Fluid Cytology - "Redefining Categories, Refining Diagnosis".

Background: The "International System of Reporting Serous Fluid Cytology (TIS)" together with cytomorphology promotes the use of ancillary techniques to resolve difficulties in reporting serous fluid cytology. Objective: To classify serous effusion fluid samples received at our department in line with "TIS", indicating the risk of malignancy (ROM), and directing appropriate usage of ancillary testing. Materials and Methods: Prospective study carried out from October 2021 to September 2022. The study included all pleural, ascitic, and pericardial fluid samples, reported according to 'TIS'. Flow cytometry and immunocytochemistry were ancillary methods utilized to assist in reporting. Cases with available history and convincing correlations didn't require further assessment. Results: A total of 1200 serous effusion samples were evaluated including 604 pleural, 591 ascitic, and 5 pericardial fluid samples. After categorization, there were 23 samples in non-diagnostic (ND, 1.9%), 575 in negative for malignancy (NFM, 47.91%), 44 in atypia of undetermined significance (AUS, 3.66%), 64 in suspicious for malignancy (SFM, 5.33%), and 494 in malignant category (MAL, 41.16%). Ancillary studies were beneficial in the recategorization of 26% (11/44) AUS cases, 29.6% (19/64) SFM cases, and it helped refine tumor characteristics in 35.42% (175/494) cases categorized as malignant. Final ROM calculated for each category: ND 25%, NFM 18.6%, AUS 66.6%, SFM 88%, and MAL 100%. Conclusion: Serous fluid is an easily obtainable sample that can provide opportunities for ancillary testing with clinical implications. In AUS and suspicious category although, diagnostic yield is increased however, a larger number of cases are required to obtain definite results.

Four-Level Cervical Disc Arthroplasty.

BACKGROUND: Multilevel anterior cervical discectomy and fusion inevitably yields a higher chance of pseudarthrosis or require more reoperations than single-level procedures. Therefore, multilevel cervical disc arthroplasty (CDA) could be an alternative surgery for cervical spondylosis, as it (particularly 3- and 4-level CDA) could preserve more functional motility than single-level disc diseases. This study aimed to investigate the clinical and radiological outcomes of 4-level CDA, a relatively infrequently indicated surgery. METHODS: The medical records of consecutive patients who underwent 4-level CDA were retrospectively reviewed. These highly selected patients typically had multilevel disc herniations with mild spondylosis. The inclusion criteria were symptomatic cervical spondylotic myelopathy, radiculopathy, or both, that were medically refractory. The clinical outcomes were assessed. The radiographic outcomes, including global and individual segmental range of motion (ROM) at C3-7, and any complications were also analyzed. RESULTS: Data from a total of 20 patients (mean age: 56 ± 8 years) with an average follow-up of 34 ± 20 months were analyzed. All patients reported improved clinical outcomes compared with that of preoperation, and the ROMs at C3-7 were not only preserved but also trended toward an increase (35 ± 8 vs 37 ± 10 degrees, pre- vs postoperation, P = 0.271) after the 4-level CDA. However, global cervical alignment remained unchanged. There was one permanent C5 radiculopathy, but no other neurological deteriorations or any reoperations occurred. CONCLUSION: For these rare but unique indications, 4-level CDA yielded clinical improvement and preserved segmental motility with low rates of complications. Four-level CDA is a safe and effective surgery, maintaining the ROM in patients with primarily disc herniations and mild spondylosis. CLINICAL RELEVANCE: For patients with mild spondylosis, whose degeneration at the cervical spine is not so severe, CDA is more suitable.

Ankle dorsiflexion range of motion and hip abductor strength can predict Lower Quarter Y-Balance Test performance in healthy males.

OBJECTIVES: The aim of the study was to assess whether strength and range of motion (ROM) of the hip and ankle are the factors determining performance in the Lower Quarter Y-Balance test (YBT-LQ). DESIGN: Cross-sectional study. PARTICIPANTS: 66 healthy males (age: 25.2±6.8 years) participated in this study. MAIN OUTCOME MEASURES: Participants underwent assessments of ankle dorsiflexion (DF) ROM, hip internal rotation (IR) ROM, external rotation (ER) ROM and isometric strength of hip abductor (ABD), extensor (EXT) and external rotators (ERS) muscles together with YBT-LQ for both legs. A forward 2-steps multiple linear regression analysis was conducted to examine the relationship between the predictor variables and the criterion variable. RESULTS: Ankle DF ROM predicted anterior (ANT) reach (R2 = 0.49; R2 = 0.33; p < 0.001). The model with hip ABD strength and ankle DF ROM explained posteromedial (PM) reach variance for stance leg (R2 = 0.35; p < 0.001), while only hip ABD strength was included for kicking leg (R2 = 0.19; p = 0.007). The model with ankle DF ROM and hip ABD strength explained posterolateral (PL) reach for stance leg (R2 = 0.41; p < 0.001). Hip ABD was the only predictor for kicking leg PL reach (R2 = 0.15; p < 0.001). YBT-LQ composite score was explained by ankle DF ROM and hip ABD strength for both legs (R2 = 0.44; p < 0.001) and (R2 = 0.25; p = 0.002). CONCLUSION: Hip ABD strength and ankle DF ROM can determine performance in the YBT-LQ. Strength of hip EXT, ERS as well as ROM of hip IR and ER did not predict YBT-LQ performance.

Dose-Response Effects of MittEcho, a Measurement Feedback System, in an Indicated Mental Health Intervention for Children in Municipal and School Services in Norway.

Including routine client feedback can increase the effectiveness of mental health interventions for children, especially when implemented as intended. Rate of implementation, or dose, of such feedback interventions has been shown to moderate results in some studies. Variation in implementation and use of client feedback may also contribute to the mixed results observed within the feedback literature. This study evaluates dose-response associations of client feedback using a novel Measurement Feedback System (MFS) within an indicated group intervention. The primary aim was to determine whether the rate of MFS implementation predicts symptom reduction in anxiety and depression among school-aged children. The secondary aim was to assess whether the rate of MFS implementation influences children's satisfaction with the group intervention or their dropout rates. Data were collected via a randomized factorial study (clinicaltrials.gov NCT04263558) across 58 primary schools in Norway. Children aged 8 to 12 years (N = 701) participated in a group-based, transdiagnostic intervention targeting elevated symptoms of anxiety or depression. Half of the child groups also received the feedback intervention using the MittEcho MFS. Group leaders (N = 83), recruited locally, facilitated the interventions. The MFS dose was measured using the Implementation Index, which combines the use of MFS by both children and providers (group leaders) into a single dose variable. Results showed no significant additional effect of dose of MFS on change in depression or anxiety scores, on user satisfaction with the intervention or on intervention dropout. The discussion addresses potential reasons for these non-significant findings and implications for MFS implementation in preventive, group-based interventions in school settings.

Biomechanical Analysis of Trapezoidal Thread Screw-Rod Fixation in Pedicle Section of Cervical Spine: A Finite-Element Analysis.

Background: Cervical pedicle screw-rod fixation presents a complex approach in spinal surgery, offering enhanced spine stabilization in variable conditions considering traumatic injuries, degenerative changes, as well as orthopaedic and oncological ailments. This technique employs small diameter screw implants strategically placed to bolster the mechanical integrity of the spine. Notably, it involves minimally invasive procedures, resulting in smaller incisions and reduced patient discomfort. This study aims to assess the effects of trapezoidal thread screws in pedicle sections of the cervical spine during flexion-extension loadings, focusing on factors such as range of motion (ROM), implant stress, and stress on adjacent bone. Methods: Utilizing CT scan data, a finite element model of the cervical spine (C2-C7 vertebrae) was prepared. Trapezoidal thread screws were integrated into a single-level pedicle screw-rod fixation at the C5-C6 vertebrae. The C2 vertebra were given a compressive load of 50 N along with a moment of 1 Nm, resulting in the immobilization of the C7. Results and Discussion: The results indicate a reduction in ROM at the C5-C6 level by 69% to 77% compared to the intact spine during flexion-extension loading, with a slight increase in ROM observed at adjacent cervical spine levels. Stress analysis revealed that the trapezoidal thread screws induced stresses ranging from 24 MPa to 29 MPa in PEEK trapezoidal screw-rod implants, which fall below the material's yield stress. Conclusions: This suggests that the trapezoidal thread profile may be advantageous in minimizing stress concentration, attributed to its larger contact area with the vertebrae bone between the threads.

Effectiveness and safety of thoracic manipulation in the treatment of neck pain: An updated systematic review and meta-analysis.

BACKGROUND: The purpose of this meta-analysis was to evaluate the effectiveness and safety of thoracic manipulation (TM) in patients with neck pain (NP). OBJECTIVE: The purpose of this meta-analysis was to evaluate the effectiveness and safety of thoracic manipulation (TM) in patients with neck pain (NP). METHODS: Seven electronic databases were searched from their inception through October 2023 by two authors. The methodological quality assessments were performed with the Physiotherapy Evidence Database (PEDro) scale. Pain, cervical range of motion (ROM), disability, and quality of life (QOL) were estimated for TM treatment in patients with NP. RESULTS: Eighteen randomized controlled trials (RCTs) with 914 patients were included with a PEDro score of 6.923 ± 3.120. Pooled effect sizes of pain (SMD =-0.481, 95% CI -0.653 to -0.309, P= 0.000), disability (SMD =-1.435, 95% CI -2.480 to -0.390, P= 0.007), QOL-physical component score (PCS) (SMD = 0.658, 95% CI 0.290 to 1.025, P= 0.000), ROM of flexion (SMD = 0.921, 95% CI 0.287 to 1.555, P= 0.000), ROM of extension (SMD = 0.572, 95% CI 0.321 to 0.822, P= 0.000), ROM of left lateral flexion (SMD = 0.593, 95% CI 0.075 to 1.112, P= 0.025) and ROM of left rotation (SMD = 0.230, 95% CI 0.010 to 0.450, P= 0.04) were favored by the TM group. CONCLUSIONS: TM provides short-term effect on relieving neck pain, increasing cervical ROM, and disability in patients with NP without serious side effects. Continuous therapy and distraction therapy are recommended as optimal choice on reducing pain and improving cervical ROM, especially in patients with chronic NP (> 3 months). The TM-induced improvements in the QOL of patients with NP should be verified by more further high-quality RCTs.

Greater cervical kyphosis during flexion increases the risk of kyphotic deformity after laminoplasty in patients with cervical spondylotic myelopathy.

Kyphotic deformity following the loss of cervical lordosis can lead to unfavourable neurological recovery after cervical laminoplasty (CLP); therefore, it is essential to identify its risk factors. Recent studies have demonstrated that the dynamic parameters of the cervical spine, based on baseline flexion/extension radiographs, are highly useful to estimate the loss of cervical lordosis after CLP. However, it remains unclear whether such dynamic parameters can predict kyphotic deformity development after CLP. Hence, the present study aimed to investigate whether the dynamic parameters could predict kyphotic deformity in patients with cervical spondylotic myelopathy (CSM) after CLP. This retrospective study included 165 patients, consisting of 10 and 155 patients with and without cervical kyphosis of C2-C7 angle ≤ -10° at the final follow-up period, respectively. Among the static and dynamic parameters of the cervical spine, greater cervical kyphosis during flexion (fC2-C7 angle) demonstrated the best discrimination between these two cohorts, with an optimal cutoff value of -27.5°. Meanwhile, greater gap range of motion (gROM = flexion ROM - extension ROM ) had the highest ability to predict a loss of ≥ 10° in C2-C7 angle after CLP, with an optimal cutoff value of 28.5°. This study suggests that in patients with CSM, fC2-C7 angle ≤ -25° on baseline radiographs is a potential risk for kyphotic deformity after CLP. In clinical practice, the patients with this criterion (fC2-C7 angle ≤ -25°) along with gROM ≥ 30° are at high risk of developing significant kyphotic deformity after CLP.

The effect of abdominal massage and in-bed ROM exercise on gastrointestinal complications and comfort in intensive care unit patients receiving enteral nutrition: A randomized controlled trial.

AIM: Abdominal massage facilitates gastric and colonic motility, reduces intra-abdominal distension and increases circulation. In-bed range of motion (ROM) exercise has effects on muscle strength, cardiac parameters and excretion. The aim of this study was to assess the effects of abdominal massage and in-bed ROM exercise on gastrointestinal complications and patient comfort in intensive care patients receiving enteral nutrition. METHODS: This randomized controlled trial was conducted in the internal intensive care units of two tertiary public hospitals. The sample consisted of 130 patients randomly assigned to three groups (abdominal massage = 44, in-bed ROM exercise = 43, control = 43). The individuals received abdominal massage and in-bed ROM exercises every morning before enteral feeding for 3 days. We assessed gastrointestinal complications and comfort levels of the patients 24 h after each intervention. RESULTS: While the differences in abdominal distention, defecation status, constipation, and gastric residual volume complications were significant (p < .05), there was no significant difference in diarrhea and vomiting (p > .05). Comfort level showed a statistically significant change in the experimental groups in the in-group comparison (p < .05). CONCLUSION: Abdominal massage and in-bed ROM exercise reduce abdominal distention, constipation and gastric residual volume. Abdominal massage affects the frequency of defecation; and, both interventions increase the comfort while reducing the pain level over time.
