Power Assistance

A power-assisted exoskeleton should be capable of reducing the burden on the wearer’s body or rendering his or her work improved and efficient. More specifically, the exoskeleton should be easy to wear, be simple to use, and provide power assistance without hindering the wearer’s movement. Therefore, it is necessary to evaluate the backdrivability, range of motion, and power-assist capability of such an exoskeleton. This evaluation identifies the pros and cons of the exoskeleton, and it serves as the basis for its subsequent development. In this study, a lightweight upper-limb power-assisted exoskeleton with high backdrivability was developed. Moreover, a motion capture system was adopted to measure and analyze the workspace of the wearer’s upper limb after the exoskeleton was worn. The results were used to evaluate the exoskeleton’s ability to support the wearer’s movement. Furthermore, a small and compact three-axis force sensor was used for power assistance, and the effect of the power assistance was evaluated by means of measuring the wearer’s surface electromyography, force, and joint angle signals. Overall, the study showed that the exoskeleton could achieve power assistance and did not affect the wearer’s movements.

Objective: During the transitional phase (ambulatory to non-ambulatory), synergies characterize the evolution of Duchenne muscular dystrophy (DMD). This study was performed to describe and quantify compensatory movements while sitting down on/rising from the floor and climbing up/down steps. Method: Eighty videos (5 children × 4 assessments × 4 tasks) were recorded quarterly in the year prior to gait loss. Compensatory movements from the videos were registered based on the Functional Evaluation Scale for DMD. Results: The most frequently observed compensatory movements were upper limb support on lower limbs/floor/handrail during all the tasks and lumbar hyperlordosis, trunk support on handrail, equinus foot, increased base of support, non-alternated descent, and pauses while climbing up/down steps. Conclusion: Climbing up/down steps showed a higher number of compensatory movements than sitting down on/rising from the floor, which seemed to be lost before climbing up/down steps in ambulatory children with DMD.

Objective:to assess functional results and quality of life in patients with rheumatoid arthritis (RA) after reverse shoulder joint replacement.Patients and methods.Examinations were made in 37 patients with RA involving the shoulder joint, who underwent shoulder joint replacement using a reverse DeltaX-tend DePuy prosthesis in 2006–2017. The investigators studied the volume of movements, the level of pain using the visual analogue scale, the function of the shoulder joint using the American Shoulder and Elbow Surgeons (ASES) Shoulder Score and the upper limb as a whole by the Disability of the Arm, Shoulder and Hand (DASH) questionnaire, a patient's functional status by the Health Assessment Questionnaire (HAQ), quality of life (QL) by EQ-5D (Euro Quolish instrument) and analyzed shoulder X-ray films before and in the late periods after surgery.Results.The volume of shoulder joint movements was found to increase. At 28.7 months postsurgery, the mean volume of flexion, abduction, and external rotation was 107.4Ѓ}15.2, 128.3Ѓ}8.5, and 46.4Ѓ}5.5°; respectively (p≤0.05). The patients experienced no pain in the late periods following surgery. Prior to surgery and at control examination, the mean ASES scores were 25.0Ѓ}4.7 and 79.4Ѓ}6.4, respectively (p≤0.05). Before surgery, the mean DASH score was 63.8Ѓ}4.2; in the late periods it decreased to 18.2Ѓ}8.6 (p ≤ 0.05). The mean preoperative HAQ score was 2.81; following surgery, it also decreased to 1.39 (p≤0.05). The postoperative EQ-5D QOL index score increased from 0.41 to 0.72. The rate of complications reached 10.8%.Conclusion.Reverse endoprosthetic replacement for end-stage shoulder joint damage (Larsen 4–5) with rotator cuff defect makes it possible to increase the volume of movements, to reduce pain, and to improve upper limb function, functional status, and quality of life in patients with RA.

Abstract Background - Although robotics assisted rehabilitation has proven to be effective in stroke rehabilitation, a limited functional improvements in Activities of Daily Life has been also observed after the administration of the robotic intervention. To this aim in this manuscript we compare the efficacy in terms of both clinical and functional outcomes of a robotic training performed with a multi-joint functional exoskeleton in goal-oriented exercises compared to a conventional physical therapy program, equally matched in terms of intensity and time. As a secondary goal of the study, it was assessed the capability of kinesiologic measurements - extracted by the exoskeleton robotic system - of predicting the rehabilitation outcomes using a set of robotic biomarkers collected at the baseline. Methods – A parallel-group randomized clinical trial was conducted within a group of 26 chronic post-stroke patients. Patients were randomly assigned to two groups receiving robotic or manual therapy. The primary outcome was the change in score on the upper extremity section of the Fugl-Meyer Assessment (FMA) scale. As secondary outcome a specifically designed bimanual functional scale, Bimanual Activity Test (BAT), was used for upper limb functional evaluation. Two robotic performance indices were extracted with the purpose of monitoring the recovery process and investigating the interrelationship between pre-treatment robotic biomarkers and post-treatment clinical improvement in the robotic group. Results – A significant clinical and functional improvements in both groups (p<0.01) was reported. More in detail a significantly higher improvement of the robotic group was observed in the proximal portion of the FMA (p<0.05) and in the timing for accomplishing the tasks of the BAT (p<0.01). The multilinear-regression analysis pointed out a significant correlation between robotic biomarkers at the baseline and change in FMA score (R2 = 0.91, p<0.05), suggesting their potential ability of predicting clinical outcomes. Conclusion – Exoskeleton-based robotic upper limb treatment might lead to better functional outcomes, if compared to manual physical therapy. The extracted robotic performance could represent predictive indices of the recovery of the upper limb. These results are promising for their potential exploitation in implementing personalized robotic therapy.

BACKGROUND: Functional stability of the shoulder requires a balance of active forces, passive forces, and control subsystems of the joint complex. Although whole-body vibration enhances shoulder muscle function and proprioception, the impact of vibration on the sensorimotor control of the shoulder joint remains unclear. OBJECTIVE: To investigate the acute effect of vibratory stimuli on the sensorimotor control of the shoulder joint. METHODS: Fifteen male participants (age, 22.7 ± 2.3 years) were included and performed the exercise in a modified push-up position with partial weight-bearing on a vibration platform with and without vibratory stimuli. The vibration protocol included six sets lasting for 30 s each with a 30-s rest between sets. The main outcome measures included the upper limb static stability test, Upper Quarter Y Balance Test (UQYBT), and electromyography data of the upper limb. RESULTS: Vibratory stimuli resulted in an increased UQYBT score (all directions; P< 0.01) and infraspinatus, serratus anterior, and lower trapezius muscle activity (P< 0.05) between pre- and post-exercise versus the control condition. Stabilometric parameters showed no significant interaction between condition and time. CONCLUSIONS: Vibratory stimuli could maximize training benefits while limiting injury risk for athletes. Our findings could guide the development of rehabilitation programs for patients with shoulder instability.
