Fifteen subjects with chronic cervical myofascial pain and concurrent dizziness of suspected cervical origin completed a retrospective questionnaire. Improvement in pain, dizziness and function were recorded on a visual analog scale (VAS) in response to a non-standardized rehabilitation program involving modalities, stretching, strengthening, trigger point injections and aerobic conditioning. Subjects reported an average VAS improvement in dizziness of 59% (±29%), pain 69% (±21%) and function 71%(±19). Seven subjects experienced reproduction of their dizziness and pain during trigger point injections. Overall, twenty seven percent reported no further episodes of dizziness. All subjects experienced a decrease in the frequency of episodes of dizziness. There was a correlation between dizziness and pa...

In general, concussions in this age range occur much more frequently in games than in practice. Also for sports in which both sexes participate, reported concussion rates are higher for female than male high school athletes. Recent data show that the time required for return to play and resolution of symptoms is similar for women and men. Very little is known about the epidemiology of concussions in middle school-aged athletes and younger children.

With proper management, the majority of injuries resolve quickly and allow for rapid return to sport. However, some of these injuries occur because of improper mechanics that adversely affect the core stability of the spine, or conversely these injuries cause instability of the spine through disruption of the spinal support mechanisms. Development of an appropriate treatment plan depends on a thorough understanding of the structures providing core stability and the exercises to correct identifiable deficits. A comprehensive rehabilitation program should include correction of flexibility and strength deficits, with subsequent progression to functional and sports-specific exercises. The purpose of this paper is to review current concepts regarding core stability and rehabilitation in the athlete.

Ultrasound revealed an area of hyperechogenicity, representing a calcification, within the interspinous ligament at the area of maximal tenderness at the T12-L1 level. Under ultrasound guidance, multiple fenestrations were made into the calcification and a mixture of lidocaine and triamcinolone was injected. The patient experienced immediate improvement in her symptoms, and resolution occurred during the subsequent 6 weeks; she was able to make a gradual return to gymnastics. Interspinous ligament calcification in a young athlete has not been previously reported.

Prospective study. Academic sports medicine center. 15 subjects undergoing arthroscopic surgery for unilateral knee injuries without previous injury to the contralateral knee. Subjects received: 1) spinal anesthesia with bupivacaine, 2) epidural anesthesia with lidocaine, 3) general anesthesia, or 4) femoral nerve block of injured leg only. Noninjured leg popliteal angle preoperatively, intraoperatively under anesthesia, and postoperatively after recovery from anesthesia. The overall mean popliteal angle was 132.5 +/- 3.1 degrees preoperatively, 134.31 +/- 11.6 degrees intraoperatively, and 130.7 +/- 10.2 degrees postoperatively. Overall, the intraoperative angle was significantly greater than the postoperative angle (p = 0.02). The mean change in popliteal angle was 8.1 +/- 2.2 degrees (Group 1), -0.4 +/- 1.9 degrees (Group 2), 0.9 +/- 1.4 degrees (Group 3), and -2.4 +/- 3.8 degrees (Group 4). There was no significant change in pre- to postoperative popliteal angle in relation to postoperative pain. Females had a greater mean popliteal angle (139.84 degrees ) compared with males (128.84 degrees ) (p = 0.04). Understanding the neuromuscular influences on muscle flexibility will assist in the development of new rehabilitative and injury preventative techniques. The present pilot study implicates neural contributions to muscle flexibility. Further studies are needed to delineate the relative contributions of neural and muscular components and to facilitate new techniques in the rehabilitation and prevention of injury.

We present two cases of symptomatic hypothermia of 34-35°C (95°F) which resolved with ingestion of calories in otherwise healthy men competing in a multi-stage ultramarathon in the Sahara desert, Egypt 2012 with ambient temperatures of approximately 38-39°C (100-102°F). Hypothermia is well documented in the medical literature as a presenting sign of hypoglycemia in both conscious and comatose patients. The mechanism by which hypoglycemia contributes to hypothermia is poorly understood, but may represent a compensatory response that reflects a decrease in energy demand during glucose deprivation. Wilderness medicine practitioners at endurance events should be cognizant of hypothermia as a potential presenting sign of hypoglycemia, as it can be empirically treated and rapidly reversed.

The goal of the study was to determine whether paper tape could prevent foot blisters in ultramarathon runners. This prospective randomized trial was undertaken during RacingThePlanet 155-mile (250-km), 7-day self-supported ultramarathons in China, Australia, Egypt, Chile, and Nepal in 2010 and 2011. Paper tape was applied prerace to one randomly selected foot, with the untreated foot acting as the own control. The study end point was development of a hot spot or blister on any location of either foot. One hundred thirty-six participants were enrolled with 90 (66%) having completed data for analysis. There were 36% women, with a mean age of 40 ± 9.4 years (range, 25-40 years) and pack weight of 11 ± 1.8 kg (range, 8-16 kg). All participants developed blisters, with 89% occurring by d...
