Sacroiliac joint dysfunction in elite rowers.

STUDY DESIGN: Cross-sectional, descriptive study. OBJECTIVES: To examine the occurrence of sacroiliac joint dysfunction (SIJD) in a group of elite rowers. BACKGROUND: Sacroiliac joint dysfunction is a common problem for elite athletes, but is largely unstudied in the medical literature. METHODS AND MEASURES: The United States Senior National Rowing Teams at the Pan American Games and the World Rowing Championships in 1995 were tested for SIJD through the standing flexion test followed by palpatory examination of anatomic landmarks. RESULTS: Sacroiliac joint dysfunction occurred in 54.1% of team members. Sacroiliac joint dysfunction was prevalent in both sweep rowers (66%) and scullers (34%). Prevalence of SIJD did not differ among the specific types of SIJD, the side of involvement, or for the handedness of sweep rowing. CONCLUSIONS: Sacroiliac joint dysfunction is an important orthopaedic problem in rowers. This information may be useful for clinicians who treat rowers and elite athletes.

Randomized controlled trial of Protonics on patellar pain, position, and function.

PURPOSE: Patellofemoral pain (PFP) and abnormal patellofemoral congruence (PFC) are common athletic problems whose treatment remains controversial. This study examined the effects of a high volume of submaximal knee muscle exercise on objective measures of PFP and PFC under a test-retest design. METHODS: A sample of 100 subjects was randomly divided into two groups: control and treatment. All subjects of both groups were tested for PFC, using a Merchant x-ray view, function, via Kujala patellofemoral score (KPS), and pain, through a visual analog scale (VAS), initially and then 4 wk later. The treatment group exercised during activities of daily living (ADL) by wearing a Protonics device; the control group did not receive treatment. RESULTS: One-way analysis of variance tests found no difference between pre- and posttest results for the control group but found significant changes in PFC, KPS, and VAS (all P < 0.001). PFC and joint function improved, and PFP decreased in all subjects of the treatment group. CONCLUSIONS/CLINICAL RELEVANCE: It was concluded that the treatment reduced PFP and PFC as compared with the control. A high volume of submaximal knee exercise seems useful for clinical patients with PFP and abnormal PFC.

The clinical and cost-effectiveness of two different programs for rehabilitation following ACL reconstruction.

Patient rehabilitation following anterior cruciate ligament reconstruction is a continuing challenge for physical therapists. This study compared the effectiveness of an established protocol to a new program which included Protonics exercise. Sixty patient (42 males and 18 females; mean age = 24.7 +/- 3.9 years; age range = 19-30 years) were randomly assigned into two groups: Group 1 received the established protocol and Group 2 received a Protonics exercise regimen. Both groups were measured for the time needed for return to unrestricted activity on the basis of objective, functional, and clinical exams; all tests were repeated at a 1-year follow-up exam. Group 2 completed treatment an average of 3.3 weeks sooner than Group 1 (mean = 19.8 vs. 23.1 weeks) at an average lower cost of $990.00 per subject. All subjects had good functional outcomes at the 1-year follow-up exam. It was concluded that the Protonics exercise program was more clinically and cost-effective than the other program, although both methods were successful for postsurgical anterior cruciate ligament rehabilitation.

The isokinetic torque curve of shoulder instability in high school baseball pitchers.

Athletes with shoulder problems are commonly referred to orthopaedic and sports physical therapists for rehabilitation. Many of these problems include some form of shoulder instability. The purpose of this study was to generate an isokinetic torque curve that is representative of the shoulder impingement syndrome that may affect high school baseball pitchers. A sample of 241 subjects, each diagnosed with an impingement syndrome in the right shoulder, was tested using a Cybex II+ dynamometer configured to duplicate the orthopaedic loose-packed and plane of the scapula positions of the shoulder complex. The subjects were tested concentrically across five maximal repetitions of internal and external rotation at the speeds of 60, 120, 180, 240, and 300 degree/sec; graphic records were collected at 60 degrees/sec. Descriptively, testing revealed a distinct isokinetic torque curve for the impingement syndrome compared with the noninvolved shoulder. This information might serve as a useful complement to traditional clinical procedures for the diagnosis of the shoulder impingement syndrome.

A randomized-control study of active and passive treatments for chronic low back pain following L5 laminectomy.

The professional literature contains relatively few randomized-control studies that have assessed the efficacy of physical therapy approaches to the management of patients with chronic low back pain (CLBP). The purposes of this study were: 1) to investigate the effects of physical agents, joint manipulation, low-tech exercise, and high-tech exercise on objective measures of CLBP; 2) to track the length of CLBP relief; and 3) to determine treatment cost-effectiveness. Two-hundred-fifty subjects (68 females, 182 males; ages 34-51 years) with CLBP following an L5 laminectomy were randomly assigned into five separate groups for a treatment period of 8 weeks. Chronic low back pain status was measured by modified-modified Schober, Cybex Liftask, and Oswestry procedures. Results revealed that: 1) only low-tech and high-tech exercise produced significant improvements (p < .05) in CLBP, 2) the mean period of CLBP relief ranged from 1.6 weeks (control) to 91.4 weeks (low-tech exercise), and 3) low-tech exercise was most cost-effective. It was concluded that: 1) low-tech and high-tech exercise were the only effective treatments for CLBP, 2) low-tech exercise produced the longest period of CLBP relief, and 3) low-tech exercise was the most cost-effective form of treatment. Clinically, low-tech exercise may be the treatment method of choice for the effective management of chronic low back pain.

Upper extremity proprioceptive training.

Proprioception following lower extremity injuries is commonly recommended, but there is little information on proprioception training following upper extremity injuries. No studies have evaluated whether proprioception programs for athletes in open kinetic chain activities (throwing, shot putting) should be different than programs for athletes in closed kinetic chain activities (gymnastics, swimming, kayaking, or rowing). In this paper, we provide a rationale for proprioception training for upper extremity injuries in athletes and the importance of analyzing the athlete's sport and activity for specificity of proprioception exercises. We then discuss one popular proprioception exercise, rhythmic stabilization, and propose several additional upper extremity proprioception exercises, along with instructions for the athletic trainer on how to direct the athlete through these exercises.

Fifteen years of amateur boxing injuries/illnesses at the United States olympic training center.

We examined the incidence of health problems in elite-level amateur boxing athletes who sparred, trained, or competed at the United States Olympic Training Center in Colorado Springs, Colorado from January 1, 1977 through June 30, 1992. We think this is the first study to examine both injuries and illnesses in a population of elite-level athletes. We collected data on 1,776 reported problems (1219 injuries, 557 illnesses) from standard medical report forms completed by the permanent and volunteer sports medicine staff. We classified the information based on type, body region, location, description, and occurrence. There were significant differences between the frequency of injuries and illnesses and between the classifications and regions for each type of problem. Collectively, serious injuries represented only a relatively small percentage (6.1%) of all problems. We concluded that illnesses comprised a small but important portion of problems, that most illnesses involved respiratory tract infections (71%), that there is only a small risk for serious injury, and that injuries occur in a hierarchy of upper extremity (441, 25%), head/face (344, 19%), lower extremity (267, 15%), and spinal column (167, 9%) for amateur boxers.

Postsurgical knee rehabilitation. A five year study of four methods and 5,381 patients.

This study was an investigation into the influences of rehabilitation procedures on the long-term success of postsurgical knee patients. In a blind retrospective paradigm, the cases of 5,381 patients (2,417 females, 2,964 males; mean age, 32.7 years; age range, 13 to 61 years) were reviewed to correlate rehabilitation methods with postsurgical success. Postsurgical success was defined as patient resumption of required activities without symptom recurrence, over a period of 5 years after surgery. The four rehabilitation methods studied were programs of no exercise, home exercise, isotonic exercise, and isokinetic exercise. Statistical analysis revealed significant differences at the P = 0.05 level for comparison of the isokinetic exercise to the other methods on the basis of rehabilitation interval (isokinetic, 8.9 +/- 3.7 weeks; isotonic, 12.3 +/- 6.1 weeks; home, 10.0 +/- 4.5 weeks) and correlation to success (isokinetic, r = 0.92, isotonic, r = 0.48, home, r = 0.09, no exercise, r = 0.00). It was concluded that rehabilitation methods that incorporate isokinetic exercise are more efficient and effective than nonisokinetic programs in the long-term successful management of postsurgical knee patients.
