AbstractThe mobility of the upper extremity is essential for everyday activities and for independent living. Shoulder disorders affect the range of motion, therefore a patient assistive system (PAS) for the shoulder joint can be used to compensate the restrictions. The developed PAS supports up to 120° of flexion and abduction. The portable dynamic orthotic consists of two levers and is attached to a hip belt. The upper arm of the patient is connected to the device using a brace. The prototype is driven by one motor and controlled by surface electromyography (EMG). The functionality of the system was successfully verified by tests with healthy subjects. For further development, a study with shoulder patients will be performed and health professionals will evaluate the PAS.

ObjectiveTo evaluate the immediate effects of pragmatic posterior capsular stretch (PPCS) on shoulder joint range of motion (ROM).MethodA quasi-experimental design was used to recruit healthy subjects of age 21.43 (±1.960) years, height 165.8 (±2.1069) cm and weight 63.90 (±13.187) kg. Inclusion criteria were grade 1 and grade 2 of the shoulder mobility test of functional movement screening. Preintervention and postintervention measurement of flexion, abduction, internal rotation (IR), external rotation (ER), reaching up behind the back (RUBTB) and reaching down behind the neck (RDBTN) were compared. A therapist-administered PPCS was the only intervention applied.ResultsPaired t-test statistics showed improvement (mean°±SD) in shoulder flexion (13.5°±8.11), abduction (11°±8.35), IR (8.5°±10.27), ER (7.83°±7.15), RUBTB (17.34°±13.81) inches and RDBTN (2.93±1.52) inches. The changes in these ROM and functional movements were statistically significant (p<0.05).ConclusionPPCS can effectively improve the functional movement of RUBTB and shoulder ROM in healthy subjects. It is recommended for the trials on prevention and rehabilitation of shoulder pathologies.Trial registration numberNCT04242888.

Compensatory Motion

The prostheses used by the majority of persons with hand/arm amputations today have a very limited range of motion. Transradial (below the elbow) amputees lose the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to the forearm) and the operation of a powered prosthetic hand. Older body-powered prostheses, incorporating hooks and other cable driven terminal devices, have even fewer degrees of freedom. In order to perform activities of daily living (ADL), a person with amputation(s) must use a greater than normal range of movement from other body joints to compensate for the loss of movement caused by the amputation. By studying the compensatory motion of prosthetic users we can understand the mechanics of how they adapt to the loss of range of motion in a given limb for select tasks. The purpose of this study is to create a biomechanical model that can predict the compensatory motion using given subject data. The simulation can then be used to select the best prosthesis for a given user, or to design prostheses that are more effective at selected tasks, once enough data has been analyzed. Joint locations necessary to accomplish the task with a given configuration are calculated by the simulation for a set of prostheses and tasks. The simulation contains a set of prosthetic configurations that are represented by parameters that consist of the degrees of freedom provided by the selected prosthesis. The simulation also contains a set of task information that includes joint constraints, and trajectories which the hand or prosthesis follows to perform the task. The simulation allows for movement in the wrist and forearm, which is dependent on the prosthetic configuration, elbow flexion, three degrees of rotation at the shoulder joint, movement of the shoulder joint about the sternoclavicular joint, and translation and rotation of the torso. All joints have definable restrictions determined by the prosthesis, and task.

Background Little information exists to guide the choice of exercise for regaining shoulder range of motion (ROM). The purpose of this study was to compare the maximal ROM reached, pain and difficulty associated with 4 commonly prescribed exercises. Methods Forty (9 females) patients with various shoulder disorders and a limited flexion ROM performed 4 exercises for regaining shoulder flexion ROM in a randomized order. Exercises included the self-assisted flexion, forward bow, table slide and rope-and-pulley. Participants were videotaped while performing all exercises and the maximal flexion angle reached during each exercise was recorded using Kinovea motion analysis freeware (Kinovea 0.8.15). Pain intensity and the perceived level of difficulty associated with each exercise were also recorded. Results The forward bow and table slide generated significantly greater ROM compared with the self-assisted flexion and rope-and-pulley (P ≤ 0.005). The self-assisted flexion was associated with a greater pain intensity compared with the table slide and rope-and-pulley (P = 0.002) and a greater perceived level of difficulty compared with the table slide (P = 0.006). Conclusions Due to the greater ROM allowed, and similar or even lower level of pain or difficulty, clinicians may wish to initially recommend the forward bow and table slide for regaining shoulder flexion ROM.

Abstract Background The shoulder joint is the most commonly injured joint in CrossFit practitioners, because of the high intensity and loads associated with this sport. Despite the large number of clinical cases, there is a shortage of studies that investigate influence of biomechanical aspects of upper limbs' injuries on CrossFit practitioners. This study hypothesized that there would be a difference in function, strength, and muscle activation between Crossfit practitioners with and without shoulder pain. Methods We divided 79 Crossfit practitioners into two groups according to whether they reported pain (n = 29) or no pain (n = 50) in the shoulder during Crossfit training. Muscle function, strength, and activation were assessed using the Disability Arm, Shoulder and Hand function questionnaire, Upper Quarter Y Balance Test and Closed Kinetic Chain Upper Extremity Stability Test shoulder tests, isometric muscle strength assessment by manual dynamometry and muscle activation by surface electromyography and pain report. Results The function based on questionnaire was associated with pain (p = 0.004). We observed a statistically significant difference between the two groups only in the surface electromyography activity of the lower trapezius, and in the variables of shoulder pain and function (p = 0.038). Conclusion Crossfit practitioners with shoulder pain occurring during training showed good function and stability of the shoulder joint, but there was a reduction in the activation of stabilizing muscles, especially the lower trapezius.

Abstract Background The study aimed to explore the additional value of repair of Lafosse I subscapularis injury compared with debridement in anterosuperior rotator cuff injury. Methods The prospective study was conducted on a total of 41 patients with supraspinatus tendon tear combined with Lafosse I subscapularis injury. Eighteen patients were divided into the repair group and 23 patients were divided into the non-repair group. The two groups were compared for intraoperative parameters, pain score, range of motion of the shoulder joint, shoulder joint function and quality of life (QoL) at pre-operation, 3 and 6 months postoperatively and the final follow-up visit. Results The width of supraspinatus tendon tear did not exceed 3 cm and did not retract beyond the glenoid in among patients. There was no statistical difference of preoperative data between two groups, including age, course of disease, positive Jobe test, positive Bear-hug test, positive Lift-off test, Patte stage, longitudinal tear and pain severity (P > 0.05). Compared to preoperative levels, the severity of pain, ASES scores and EQ-5D-3L scores were significantly lower at 3 and 6 months postoperatively and the final position (P < 0.05). However, there was no statistical difference in pain severity, ASES scores and EQ-5D-3L scores between repair group and non-repair group (P > 0.05). Similarly, compared to preoperative levels, the range of motion of shoulder joint was significantly improved after operation, including internal rotation, external rotation, forward flexion and elevation (P < 0.05). However, there was no statistical difference in range of motion of shoulder joint between repair group and non-repair group (P > 0.05). Conclusion Operative treatment can effectively lessen severity of pain in the patients, improve shoulder joint function, increase the range of motion of the shoulder joint and enhance the QoL in treating anterosuperior rotator cuff injury. However, repair of subscapularis brings no benefit compared to debridement in treating supraspinatus tendon tear combined with Lafosse I subscapularis injury.

IntroductionEmotion regulation (ER) efficiency dwells among the most pressing issues of contemporary psychology and psychiatry. Further development of the methods of reliable assessments for ER makes it the task of current importance.ObjectiveTo modify Rosenzweig Picture-Frustration Test for the study of ER in health and in disease.MethodsIn the initial stage of testing participants had to look through a succession of Rosenzweig's pictures, and select potentially traumatizing situations.In the second stage they answered the following questions:– what would you say in this particular situation?– what would you have in mind, saying this?– could you think of an answer that would taper down the traumatizing character of the situation in your own perception? (Zinchenko, Pervichko, 2014).A total of 85 patients with stress-induced hypertension (mean age was 45.9 ± 2.8) and 82 healthy subjects (mean age was 44.9 ± 3.1) took part in the study.ResultsWe came to distinguish among four classes of ER strategies: internal, cognitively non-mediated; internal, cognitively transforming; external, cognitively non-mediated; and external, cognitively transforming (Pervichko, 2015). Hypertensive patients significantly more frequently than healthy subjects reveal wider set of emotionally grave events (19.8% vs 11.2%, P < 0.001), they are more prone to rumination, disasterization (19.0% vs 11.1%, P < 0.001) and suppression in display of their emotions (31.9% vs 20.2%, P < 0.001). The patients will seldom employ the strategy of interactive subject–subject transformations; their capability to actualize new meanings in traumatic situations is diminished.ConclusionsApplication of the described modification of Rosenzweig Picture-Frustration Test allows to distinguish and classify various ER strategies, and to demonstrate peculiarities in ER related behaviour of hypertensive patients as opposed to healthy subjects.Disclosure of interestThe authors have not supplied their declaration of competing interest.
