Comparative StudyContralateral tendon rupture risk is increased in individuals with a previous Achilles tendon rupture.
The purpose of this study was to examine the outcome after surgery for an acute Achilles tendon rupture. In particular, we wanted to study whether persons who have suffered an Achilles tendon rupture are at greater risk of a contralateral tendon rupture. From September 1990 to April 1997, 168 acute Achilles tendon ruptures in 26 women and 142 men were treated operatively. ⋯ Ten patients (6%) experienced a rupture on the contralateral side during the follow-up period (OR: 176 [70-282] vs. the expected rate based on the general population risk of this injury, P<0.001). Thus, this study suggests that patients with an Achilles tendon rupture are at significantly increased risk of a contralateral tendon rupture, as well. Also, as many as half of the patients suffered from post-injury problems at long-term follow-up.

Comparative StudyPredictors of 6-minute walk test results in lean, obese and morbidly obese women.
The aim of this study was first, to assess the presence of medical conditions that might interfere with walking; second, to assess the differences in walking capacity, perceived exertion and physical complaints between lean, obese and morbidly obese women; and third, to identify anthropometric, physical fitness and physical activity variables that contribute to the variability in the distance achieved during a 6-minute walk test in lean and obese women. A total of 85 overweight and obese females (18-65 years, body mass index (BMI) > or = 27.5 kg m(-2)), 133 morbidly obese females (BMI > or = 35 kg m-2) and 82 age-matched sedentary lean female volunteers (BMI < or = 26 kg m(-2)) were recruited. Patients suffering from severe musculoskeletal and cardiopulmonary disease were excluded from the study. ⋯ In a multiple regression analysis, 75% of the variance in walking distance could be explained by BMI, peakVO2, quadriceps muscle strength age, and hours TV watching or sports participation. These data suggest that in contrast with lean women, walking ability of obese women is hampered not only by overweight, reduced aerobic capacity and a sedentary life style, but also by perceived discomfort and pain. Advice or programs aimed at increasing walking for exercise also need to address the conditions that interfere with walking, as well as perceived symptoms and walking difficulties in order to improve participation and compliance.

Patellofemoral pain syndrome: pain, coping strategies and degree of well-being.
The purpose of this study was to evaluate how patients with patellofemoral pain syndrome (PFPS) experience their pain, what coping strategies they use for the pain, and their degree of well-being. Fifty patients, 15-52 years old, with PFPS were evaluated with multidimensional pain inventory (MPI), coping strategies questionnaire (CSQ) and Spielberger state trait anxiety inventory (STAI). Reliability of the evaluation methods was established for 12 patients. ⋯ The STAI scores were in general found to be somewhat higher than the scores found in the literature on healthy subjects. It is concluded that the way patients with PFPS experience their pain, the coping strategies for pain they use and their degree of well-being, are in agreement with other patient groups who have chronic pain. Some concern is raised in terms of the high scores reported for the coping strategy "catastrophizing" .

Effects of 12-week shooting training and mode of feedback on shooting scores among novice shooters.
The mode of feedback has been shown to have an effect on motor skill learning. This study investigated effects of an intensive 12-week shooting training period, and of the mode of feedback on scores in standing and running target shooting among 30 novices with limited shooting experience. They were divided into one control (no training) and three training groups. ⋯ Each training group improved their scores in the running target shooting. There were no significant differences between the three training groups in improvements of sum scores (performance outcome). The current study showed that among novice shooters both KR alone and KR+KP improved running target shooting outcome, and that KR and KP together did not lead to a significantly better shooting performance than KR alone.

Post-exercise muscle soreness after eccentric exercise: psychophysical effects and implications on mean arterial pressure.
The aim of the study was to examine the time course of changes in pressure pain threshold (PPT), visual analogue scale (VAS) pain and tenderness scores, McGill Pain Questionnaire (MPQ) descriptors, pain areas, skin temperature and mean arterial pressure (MAP) following intensive eccentric exercise. In 11 healthy male subjects, eccentric exercise of the first dorsal interosseous muscle (FDI) of the right hand with 114% maximum voluntary contraction weight (MVC) was used to induce post-exercise muscle soreness (PEMS) in the right hand, while the left hand served as a control. At 24 h to 48 h all the pain profiles indicated the presence of PEMS in the right hand when compared to before exercise (P<0.05). ⋯ Skin temperature measured in the first web space of the hand did not change at any time. MAP was significantly reduced at 48 h. It is concluded that eccentric exercise of a small hand muscle is followed by PEMS and a reduced MAP after 48 h that may suggest a role of central mechanisms in the PEMS, thereby giving further insight into clinical aspects of muscle pain.
