    • "Among the variables not considered a predictive factor is the side recognition task by motor imagery. We included this variable in the baseline assessment based on fairly recent articles that suggest the possibility of a relationship between deficits in central programming and peripheral injury (Moseley & Barnett, 2009; Stenekes et al., 2009); however, little is known on the subject. Therefore, the inclusion of this test had an exploratory aspect, and the fact that it was not considered a predictor for ankle sprain gives an indication that this may also be a test that cannot detect subtle differences.

    ABSTRACT: The ankle is the joint most affected among the sports-related injuries. The current study investigated whether certain intrinsic factors could predict ankle sprains in active students. The 125 participants were submitted to a baseline assessment in a single session were then followed-up for 52 weeks regarding the occurrence of sprain. The baseline assessment were performed in both ankles and included the questionnaire Cumberland ankle instability tool - Portuguese, the foot lift test, dorsiflexion range of motion, Star Excursion Balance Test (SEBT), the side recognition task, body mass index, and history of previous sprain. Two groups were used for analysis: one with those who suffered an ankle sprain and the other with those who did not suffer an ankle sprain. After Cox regression analysis, participants with history of previous sprain were twice as likely to suffer subsequent sprains [hazard ratio (HR) 2.21 and 95% confidence interval (CI) 1.07-4.57] and people with better performance on the SEBT in the postero-lateral (PL) direction were less likely to suffer a sprain (HR 0.96 and 95% CI 0.92-0.99). History of previous sprain was the strongest predictive factor and a weak performance on SEBT PL was also considered a predictive factor for ankle sprains.

    ABSTRACT: Acute burn patients suffer pain and secondary hyperalgesia. This alters movement patterns and impairs function. Non-pharmacological methods of treatment are limited and lack rigorous testing and evidence for use. The treatment in this case series was designed to direct conscious attention to, and normalise sensation of, the injured limb in pain free way. The aim of the study was to describe a cortical training programme (CTP) in acute upper limb burn patients and to investigate the efficacy, safety and feasibility of the protocol. The study is a descriptive case series (n=6). Study tasks engaged sensory and motor nerves to influence the perception of the injured area. Visual and tactile inputs to maintain and, or normalise the homuncular map were central to the intervention. One patient, who commenced the study without resting pain, responded negatively. The remaining five patients had reduced pain and fear avoidance behaviours with associated improvement in arm function. The CTP approach is safe and feasible for use with acute burn patients where pain is reported at rest. Comparative studies are required to determine the relative efficacy of the program to usual interventions and the patients who may benefit from the technique.

    ABSTRACT: The literature suggests a beneficial effect of motor imagery (MI) if combined with physical practice, but detailed descriptions of MI training session (MITS) elements and temporal parameters are lacking. The aim of this review was to identify the characteristics of a successful MITS and compare these for different disciplines, MI session types, task focus, age, gender and MI modification during intervention. An extended systematic literature search using 24 databases was performed for five disciplines: Education, Medicine, Music, Psychology and Sports. References that described an MI intervention that focused on motor skills, performance or strength improvement were included. Information describing 17 MITS elements was extracted based on the PETTLEP (physical, environment, timing, task, learning, emotion, perspective) approach. Seven elements describing the MITS temporal parameters were calculated: study duration, intervention duration, MITS duration, total MITS count, MITS per week, MI trials per MITS and total MI training time. Both independent reviewers found 96% congruity, which was tested on a random sample of 20% of all references. After selection, 133 studies reporting 141 MI interventions were included. The locations of the MITS and position of the participants during MI were task-specific. Participants received acoustic detailed MI instructions, which were mostly standardised and live. During MI practice, participants kept their eyes closed. MI training was performed from an internal perspective with a kinaesthetic mode. Changes in MI content, duration and dosage were reported in 31 MI interventions. Familiarisation sessions before the start of the MI intervention were mentioned in 17 reports. MI interventions focused with decreasing relevance on motor-, cognitive- and strength-focused tasks. Average study intervention lasted 34 days, with participants practicing MI on average three times per week for 17 minutes, with 34 MI trials. Average total MI time was 178 minutes including 13 MITS. Reporting rate varied between 25.5% and 95.5%. MITS elements of successful interventions were individual, supervised and non-directed sessions, added after physical practice. Successful design characteristics were dominant in the Psychology literature, in interventions focusing on motor and strength-related tasks, in interventions with participants aged 20 to 29 years old, and in MI interventions including participants of both genders. Systematic searching of the MI literature was constrained by the lack of a defined MeSH term.
