Veteran soccer players had a higher sonographic prevalence of knee OA but better pain scores than a matched group of athletically active military personnel.

Robots can play a significant role as assistive devices for people with movement impairment and mild cognitive deficit. In this paper we present an overview of the lightweight i-Walk intelligent robotic rollator, which offers cognitive and mobility assistance to the elderly and to people with light to moderate mobility impairment. The utility, usability, safety and technical performance of the device is investigated through a clinical study, which took place at a rehabilitation center in Greece involving real patients with mild to moderate cognitive and mobility impairment. This first evaluation study comprised a set of scenarios in a number of pre-defined use cases, including physical rehabilitation exercises, as well as mobility and ambulation involved in typical daily living activities of the patients. The design and implementation of this study is discussed in detail, along with the obtained results, which include both an objective and a subjective evaluation of the system operation, based on a set of technical performance measures and a validated questionnaire for the analysis of qualitative data, respectively. The study shows that the technical modules performed satisfactory under real conditions, and that the users generally hold very positive views of the platform, considering it safe and reliable.

We report the case of a 16-year-old elite gymnast who presented with recurring pain in the left shoulder after training. The athlete recalled an injury to the shoulder 2 years ago. Clinically a localized tenderness to the anterior shoulder and loss of strength and range of motion was noted. Imaging investigation suggested a neglected lesser tuberosity avulsion. The athlete was treated with open excision of the deformed tuberosity and direct repair of the subscapularis to the humeral head. Following a careful postoperative rehabilitation protocol the athlete was able to return to unrestricted gymnastics after 6 months. After surgery the athlete followed a intense rehabilitation program that allowed him to return to sports at 6 months. At 5-years follow-up, the athlete was asymptomatic and competing at an international level. Avulsion fractures of the lesser tuberosity are extremely rare injuries with significant shoulder disability if left untreated. Anatomic repair can yield excellent results, even in neglected cases.

This is the first study, at least to the knowledge of the authors, which focuses merely on measuring the satisfaction of the users from the used assistive device, while exploring the Assistive Technology Device Predisposition Assessment - Device Form in such depth. According to the results, it is a stable, valid and reliable instrument and applicable to the Greek population. Thus, it can be used to measure the satisfaction of patients with assistive devices. Implications for Rehabilitation The paper explores the cultural adaptability and applicability of ATD PA - Device Form. ATD PA - Device Form can be used to assess user satisfaction by the selected assistive device. ATD PA - Device Form is a valid and reliable instrument in measuring users' satisfaction in Greekreality.
