The Impact

(1) Background: Reconditioning of the paraspinal lumbar extensor muscles by isolated lumbar extension resistance exercises (ILEX) has shown good clinical results for patients with chronic unspecific low back pain. However, the clinical value and safety for patients with specific spine pathologies is unclear. In this study, clinical outcome and influencing factors were retrospectively analyzed for patients with lumbar disk herniation (LDH) and radiculopathy. (2) Methods: 189 consecutive patients (123 men and 66 women; mean age, 36 years) with clinically diagnosed LDH and relative indications for surgery started a 9-week rehabilitation program (2x/week) including ILEX in limited range of motion (ROM) adjusted to patients’ symptoms. Patients diagnosed with advanced levels of spine degeneration were excluded. Pain/radiculopathy (PR), influence on mental health (IOMH), satisfaction rates were measured via Numeric Rating Scales (NRS, 0–10), and overall clinical outcome was stated in % (100% = full recovery). Isometric extension strength was tested before and after the program. (3) Results: 168 patients (88.9%) completed the program. For 162 out of 168 patients (96.4%) there was a significant reduction of clinical symptoms, whereas 6 patients reported no changes in symptoms. Scores (mean) for symptom intensity decreased from 4.2 (±1.5) to 1.9 (±1.5) (p < 0.001), the impact on mental health decreased from 5.9 (±2.3) to 2.4 (±2.0) (p < 0.001). There was a (weak) correlation between lower scores for PR and IOMH before the study and better clinical outcomes; PR also weakly correlated with satisfaction. Other factors such as age, strength increase, level/location and number of LDH did not have a significant impact on the clinical results. (4) Conclusion: The results indicate that ILEX in limited ROM can be an effective treatment for the majority of patients with LDH. For patients with high pain levels, the results are less consistent, and surgery may be considered.

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.

Bilateral Posterior Shoulder Dislocation

AbstractIntroduction. Bilateral posterior dislocation of the shoulder is a rare injury, accounted for about 2–5% of all shoulder dislocations. Main courses are electrical shock, epilepsy or extreme trauma with uncontrolled muscle forces. We report about a case of bilateral posterior shoulder dislocation without additional fractures but with a concomitant acromioclavicular joint dislocation. Case presentation. A 46-year-old Caucasian motorcyclist presented to our facility after a fall on slippery ground. He claimed pain in both shoulders with limited range of motion. The initial X-rays were inconclusive, clinical examination showed typical findings of a Rockwood injury with an additional limited external rotation so that a posterior shoulder dislocation was suspected. The CT scan confirmed the clinical suspicion. A closed reduction was performed followed by immobilization in a shoulder abduction pillow for 4 weeks and continuous physiotherapy. Upon follow up normal function with full range of motion was observed. Conclusion. A bilateral posterior shoulder dislocation can be caused by trauma and results in a limited range of motion with often additional injuries. Due to the unusually presentation the risk of missing the injury is increased. Therefore it is most important to consider this rare diagnosis and in case of clinical suspicion perform a careful algorithm of diagnostic.

A practical method is shown for designing four-bar mechanisms having a prescribed transmission ratio held within prescribed tolerances, for a limited range of motion. Such mechanisms may economically replace gears in many applications. Charts enable the designer to choose the mechanism having the best transmission angle possible.

Charcot arthropathy is a chronic, degenerative condition and is associated with decreased sensorial innervation. Numerous causes of this arthropathy have been described. Here we report a case of neuropathic arthropathy secondary to syringomyelia which was misdiagnosed as a soft tissue tumor and treated surgically and additionally with radiotherapy at another institution. The patient had clinical and radiological signs of syringomyelia, associated with a limited range of motion, swelling, and pain in the affected joint. Neuropathic arthropathy, although less common, should be considered in cases of unexplained joint swelling, pain, and limited range of motion of the affected joint.

Robot Head

This paper presents the development of a mechanism for actuating a sphere holonomically about 3 degrees of freedom (DOF). The target application is a robot head for mounting inside a vehicle to provide a driver with companionship, location specific information, and other assistance, via head motions in conjunction with auditory communication. Prior art is reviewed and two designs are presented: One mechanism is located below the sphere and provides an unlimited range of motion (ROM), and the other is contained entirely within the sphere but has a limited range of motion. The latter is stable and easily mounted, provides a clean appearance, and is particularly suited to human interaction applications.
