Finger Drop: Cervical Radiculopathy, Peripheral Nerve Lesion, or Multifocal Neuropathy? A Case Report
Authors: Kudlac Megan , Cummings Ryan , Finocchiaro Julie 
Published: June 2024

Background Posterior interosseous nerve (PIN) lesions can result in finger drop. Multifocal neuropathy (MFN) occurs when a primary nerve disorder predisposes the nerve to further injury. Case Presentation A 69-year-old male presented with left-handed weakness and left-sided pain of the neck, upper trapezius, and medial scapular border 4 weeks after an asymptomatic fall. Findings regarding proximal pain were consistent with cervical radiculopathy (CR). Distal weakness indicated a PIN lesion: spared sensation/supination, limited finger extension, and radial deviation upon wrist extension. MFN was considered based on history/presentation. The care team included a physical therapist, a neurosurgeon, and a hand therapist. Outcome and Follow-up Resolution of CR pain occurred at 1 month; finger extension/grip strength improved at 3 months but was less than anticipated. Discussion With neurogenic weakness, one needs to consider central- and peripheral-mediated origins, MFN contributions, and appropriate referrals.

Blood Flow Restriction Training for Subacromial Pain: Two Case Reports
Authors: Miller Matthew , Zeppieri Giorgio , Farmer Kevin W. , Pozzi Federico 
Published: June 2024

Background Blood flow restriction training (BFRT) appears to promote the strengthening of shoulder muscles, but primary clinical applications are limited to the lower extremity. Case Presentation Two female recreational athletes (Case A: 27 years old; Case B: 28 years old) with subacromial pain were treated with BFRT (50% occlusion) during 3 isotonic strengthening exercises of the upper extremity against 20% of the maximal isometric strength. At the beginning of each treatment week, we measured strength with a handheld dynamometer to ensure appropriate load progression. Outcome and Follow-Up Case A completed 16 visits and Case B completed 22 visits of BFRT with no adverse events. At discharge, we found meaningful improvement for patient-reported function, clinical measures of shoulder flexion and external-rotation range of motion and isometric strength, supraspinatus and infraspinatus cross-sectional area, and upper extremity performance. Discussion BFRT may be a valuable adjunct to standard rehabilitation for the conservative management of subacromial pain. Despite the inherent limitations of our design, we believe these preliminary findings are compelling to warrant future investigations. JOSPT Cases 2022;2(2):55–61. doi:10.2519/josptcases.2022.10867
Electrophysiological Evaluation of a Patient With Chronic Erb-Duchenne Palsy (C5-C6): A Case Study
Authors: Greathouse David G. , Painter Elizabeth E. 
Published: June 2024

Background Erb-Duchenne palsy describes injury to the upper trunk of the brachial plexus or the C5 and C6 nerve roots. It typically occurs from a traction injury that increases the angle between the head and shoulder girdle, placing excessive strain on the cervical nerve roots and brachial plexus. Injury to the C5 and C6 nerve roots and/or upper trunk of the brachial plexus results in severe shoulder girdle weakness with preservation of the hand intrinsic muscles and some forearm motions. 2 , 9 Case Presentation A 64-year-old right-hand–dominant male was referred by his orthopaedic surgeon for electromyograhy (EMG) and nerve conduction studies (NCS) to evaluate the nerve and muscle structures in the right upper extremity prior to surgical fusion of the glenohumeral joint for chronic humeral head subluxation and shoulder instability. The patient was diagnosed with a right Erb-Duchenne palsy following a hit-and-run motor vehicle accident in 2001. Physical examination revealed muscle weakness in all muscles representative of the right C5-C6 myotomes and absent biceps brachii and brachioradialis muscle stretch reflexes. Outcome and Follow Up The clinical exam findings and electrophysiological testing evidence suggested that the patient had a chronic right C5-C6 radiculopathy affecting the right upper extremity and the right mid cervical paravertebral muscles, consistent with the referring diagnosis of Erb-Duchenne palsy. Needle EMG findings suggested little chance of further neurological recovery, so the patient underwent a right glenohumeral joint fusion to improve the stability of the right shoulder and limit glenohumeral subluxation. Discussion This case study highlights the role of a thorough neuromusculoskeletal exam in the differential diagnostic process for a patient with a right C5-C6 Erb-Duchenne palsy, and the role of EMG and NCS in distinguishing brachial plexopathy from cervical radiculopathy. Additionally, EMG and NCS provided prognostic information on potential neurological recovery, suggesting that surgical fusion was the best intervention. JOSPT Cases 2022;2(3):152–158.

Acute Tibial Tuberosity Avulsion Fracture in a Male Adolescent Footballer: A Case Report
Authors: Meredith Alex 
Published: June 2024

BACKGROUND: Acute tibial tuberosity avulsion fractures are a rare injury and can occur in sporting adolescent athletes. CASE PRESENTATION: As the player (a footballer playing in central defense) kicked a ball, they suffered an acute tibial tuberosity avulsion fracture while planting their left leg. OUTCOME AND FOLLOW-UP: The player underwent open reduction and internal fixation surgery to stabilize the fracture site. A progressive 5-stage rehabilitation program followed. The player returned to competitive games 42 weeks after injury. Given the limited research into rehabilitation approaches following these injuries, the purpose of this case study was to provide an accessible framework of rehabilitation to guide practitioners in the future. A loss of 8° range of motion in knee flexion was observed; however, no other side effects were observed throughout the rehabilitation. DISCUSSION: Good clinical outcomes have been previously reported for such injuries, which this case study would further support. JOSPT Cases 2023;3(1):1–7.

Implementation of Cognitive Retraining to Diminish Kinesiophobia Associated With Chronic Ankle Instability: A Case Report
Authors: Colgan Kaitlyn , Lopes Alexandre , Nolan David 
Published: June 2024

BACKGROUND: In musculoskeletal patients, the incidence of chronic ankle instability is among the highest musculoskeletal impairments in athletes, often accompanied by kinesiophobia and fear-avoidance behaviors. Although the diagnosis of chronic ankle instability is common, there is limited literature available regarding the implementation of cognitive strategies to decrease kinesiophobia throughout rehabilitation. CASE PRESENTATION: This case describes a 28-year-old female patient who suffered an acute-on-chronic left ankle sprain 1 year before instability symptoms progressed to the point that she sought medical care in the form of a surgical ligamentous repair and arthroscopic debridement. On evaluation, she presented with high levels of kinesiophobia and fear avoidance secondary to the chronic nature of her ankle pain/instability. The use of cognitive retraining strategies and a structured physical therapy program was implemented to improve patient outcomes and allow her to return to recreational sport. OUTCOMES: The patient was able to demonstrate full return to recreational and work activities without complaints of instability or fear of reinjury. She exceeded meaningful clinically important differences (MCIDs) in all outcomes (Figure 1): Tampa Scale of Kinesiophobia (13-point change; MCID: 6 points), 17 , 25 , 28 Pain and Anxiety Symptom Scale (27-point reduction), 21 , 22 , 27 Foot and Ankle Ability Measure (12-point improvement in ADL subscale; MCID: 8 points), 4 , 20 and 100-point improvement in the Sports subscale, MCID: 9 points). 4 , 20 Literature has found that a score below 22 on the Tampa Scale of Kinesiophobia demonstrates a subclinical level of kinesiophobia, and this patient was able to achieve a score of 21 at discharge, indicative of a significant reduction in fear-avoidance and kinesiophobia tendencies. 28 JOSPT Cases 2023;3(1):16–20.

Hypertrophy of the Subclavius Muscle in Conjunction With Atrophy of the Pectoralis Muscles Postmastectomy: A Cadaveric Case Study
Authors: Jones Beth Moody , Carey Fred J. 
Published: June 2024

BACKGROUND: Musculoskeletal impairments of the upper extremity following mastectomy are well documented, although the cause of these impairments is not always known. CASE PRESENTATION: Asymmetry of the shoulder girdle musculature was found during anterior chest wall dissection of a female cadaver with a history of a left mastectomy at the age of 45 years (age at death: 96 years). The left pectoralis major and minor muscles were markedly smaller than the contralateral pectoralis muscles, whereas the converse was apparent for the subclavius muscles. OUTCOME AND FOLLOW-UP: In situ measurements of the depth of the bellies of the subclavius muscles demonstrated that the left subclavius depth was nearly twice that of the right on the initial donor. Measurements of the length and wet weight of the muscles confirmed both the increased size and mass of the left subclavius. Further research on an additional 21 pairs of subclavius included 2 additional donors with a mastectomy. When pooled with the original donor's data, the combined 3 subclavius pairs following mastectomy showed a statistical difference in mass (a1 = .05, P = .0354) and width (a1 = .05, P = .0014). DISCUSSION: The pattern of atrophy of the pectoralis muscles in our primary case suggests that the medial pectoral nerve was damaged during surgery or during postoperative treatment. How this led to the apparent hypertrophy of the left subclavius muscle is unclear. It is possible that because of the atrophy and associated weakness of the left pectoralis muscles, the left subclavius muscle took on a greater role in shoulder girdle stabilization, increasing in size and mass over time.

Knee Flexion Range-of-Motion Restriction Following Anterior Cruciate Ligament Reconstruction: A Retrospective Case Report
Authors: Piraino Kathryn 
Published: June 2024

BACKGROUND: Anterior cruciate ligament tears are a commonly encountered orthopedic knee injury. Only a few studies focus on interventions to restore knee flexion range of motion. The purpose of this case report is to describe the restoration of motion following anterior cruciate ligament reconstruction. CASE PRESENTATION: A 26-year-old man with a traumatic knee injury resulting in a right anterior cruciate ligament tear, joint effusion, decreased knee range of motion (ROM), and decreased strength managed conservatively for 3 months. OUTCOME AND FOLLOW-UP: Restoration of knee flexion ROM was achieved at 16 weeks postoperatively utilizing targeted interventions intended to restore meniscal gliding. The patient maintained knee ROM at 8 months following anterior cruciate ligament reconstruction. DISCUSSION: When a soft end-feel, posterior knee pain, and reduced flexion ROM are present, tibiofemoral joint mobilizations are a targeted intervention to improve meniscal gliding. The utilization of multimodal interventions assisted in the recovery of functional knee ROM and improved pain. JOSPT Cases 2023;3(3):202-205. Epub: 10 July 2023. doi:10.2519/josptcases.2023.11771

Published: June 2024

Рассмотрены недостатки и преимущества применения одного из методов современной теории управления – метода динамической компенсации для синтеза систем управления с запаздыванием. Цель исследования – анализ влияния факторов, снижающих качество работы системы управления, синтезируемой на основе применения принципа динамической компенсации. Объект исследования характеризуется наличием неизменяемого запаздывания и отсутствием полной информации о состоянии системы. Обоснована целесообразность применения обратных моделей для объектов с любой инерционностью для улучшения качества интегральной оценки и динамической ошибки системы управления, что подтверждено результатамивычислений и проведенных исследований. Отмечено, что получение производных при использованиитолько выходной переменной объекта для реализации обратной модели в системе с обратной связью по выходу на практике затруднено. С учетом этого рекомендуется использование вместо производных от выходной переменной объекта оценок переменных состояния, получаемых с использованием наблюдателей состояний.
The disadvantages and advantages of using one of the methods of modern control theory – themethod of dynamic compensation for the synthesis of control systems with a delay are considered. The purpose ofthe study is to analyze the influence of factors that reduce the quality of the control system, synthesized on the basis of the application of the principle of dynamic compensation. The object of the study is characterized by the presence of an immeasurable delay and the lack of complete information about the state of the system. The expediency of using inverse models for objects with any inertia to improve the quality of integral estimation and dynamic error of thecontrol system is substantiated, which is confirmed by the results of calculations and conducted research. It is noted that obtaining derivatives when using only the output variable of an object to implement an inverse model in asystem with output feedback is difficult in practice. With this in mind, it is recommended to use estimates of state variables obtained using state observers instead of those derived from the output variable of the object.

In the annex to the development of training and educational complexes, a formalized assessment of the operator’s control actions is given depending on the technical parameters of the control object. It is assumed that the operator's assessment of the object during normal operation is based on the natural frequencies of vibrations and damping coefficients. Based on various representations of control actions, quality parameters and functionals are developed to evaluate the simulation characteristics of operator training complexes. For a number of ergatic systems, models of control actions have been developed and the influence of object parameters on control characteristics has been assessed. Based on the given simulation characteristics of training complexes for training operators of ergatic systems, an assessment is made of the parameters for integrating the equations of motion in the simulator of the dynamics of the control object (used in the development of dynamics simulators for transport systems).

Atresia anal: reporte de un caso
Authors: Huerta Gil Andres Jesus , Rivera Morales Emily Nicole 
Published: June 2024

Se describe el caso de una paciente con atresia anal. El ano imperforado o atresia anal es una malformación anorrectal congénita en la que no existe una abertura anal normal al nacer. Aproximadamente la mitad de los pacientes con atresia anal también tienen anomalías de otros sistemas de órganos. El diagnóstico tardío puede ocurrir en uno de cada cinco recién nacidos, a pesar de la evaluación posparto de rutina. Tal retraso puede aumentar la morbilidad y la mortalidad. Se reporta el caso de una fémina de 2 meses y 15 días de edad, quien acudió en compañía de su madre a primer control de niño sano en un centro de salud tipo A en una parroquia rural. En esta paciente es importante destacar que no había recibido ningún control médico hasta que llego a nuestro centro de salud a los 2 meses y 25 días de nacida. Durante la exploración física se evidencio la ausencia de ano y la evacuación de heces a través de la vagina (cloaca) si bien es cierto que el diagnóstico tardío puede ocurrir en uno de cada cinco recién nacidos, en esta paciente el retraso fue de más de 2 meses lo cual no pudimos encontrar casos similares en la literatura.
