It’s not too late to exercise years after knee arthroscopy
Feb 22nd
Meniscus tears in the knee are relatively common, particularly in middle-aged athletic individuals. Arthroscopic surgery is often performed to remove damaged cartilage. Surprisingly, some orthopedic surgeons do not prescribe physical therapy after knee arthroscopy, feeling patients can recover on their own with a few simple exercises. Unfortunately, this may lead to long-term deficits in strength, range of motion, and function. Such deficits may predispose patients to knee osteoarthritis as well.
Scandinavian researchers wanted to evaluate the effects of a functional proprioceptive-based exercise program several years after arthroscopic meniscectomy. 30 patients at 4 years after their surgery were randomly assigned to the functional training group or a non-exercising control group. Both groups were tested for functional performance, strength, and self-reported pain and quality of life before and after the 4 month study.
The exercise group was led by a physiotherapist 3 times per week. A neuromuscular exercise program was developed including foam pads, balance boards and mini-trampolines. The program emphasized closed kinetic chain exercises, muscular coactivation, reactive neuromuscular training, and functional alignment. After 4 months, the functional exercise group had significantly better function and strength than the control group.
While improvements in strength and function can be expected in an exercise group compared to a non-exercising More >
Proprioceptive Exercises: Are they effective?
Feb 4th
Neuromuscular and proprioceptive exercises are increasing in popularity during rehabilitation following sports injuries such as ankle sprains and ACL tears. These interventions typically include balance exercises such as Thera-Band® kicks and balance board training. Researchers from Germany completed a systematic review of studies evaluating the effectiveness of proprioceptive and neuromuscular training. 15 clinical trials involving ankle sprains and ACL rehabilitation met the researchers’ inclusion criteria.
The authors concluded that proprioceptive exercise and neuromuscular training are effective at improving function, decreasing symptoms of instability, and preventing re-injury after ankle sprains. Surprisingly, the authors concluded that neuromuscular training was not more effective than strengthening exercise for post-operative ACL reconstruction. In addition, proprioceptive training after injury had no effect on muscle strength, muscle activation or edema, and had more impact on dynamic balance than static balance. There was conflicting evidence on training effects on joint position sense and muscle reaction.
The researchers recommended that training must last 6 to 12 weeks, but the wide variety of exercise and prescription (volume and intensity) made it difficult to recommend specific dosages of exercise. They also commented on the poor methodological quality, lack of applicable studies on shoulder exercises, and need for more research. Based on the evidence, there is moderate evidence that proprioceptive exercises should More >
Balance Training Reduces Ankle Re-Injury
Dec 3rd
Approximately 23,000 ankle sprains occur daily in the United States, and about one half require some form of medical treatment. Research has shown that athletes are twice as likely to re-injure their ankle within one year. According to a study in the British Medical Journal, athletes with ankle sprains who receive additional proprioceptive training after ‘usual care’ are 35% less likely to suffer a recurrence over the next year. Over 500 athletes in the Netherlands were randomly assigned to usual care (the control group) or usual care plus 8 weeks of balance board exercises. The ankle exercises were performed 3 times per week, 30 minutes per session as part of normal warm-up before sports. The program gradually increased in difficulty.

The authors concluded that the 8 week balance training program would benefit both athletes and the general population after suffering an ankle sprain. The results of this study were similar to findings in a 2004 study where volleyball players in the Netherlands significantly reduced their risk of re-injury after a balance board training program. Another study on American high school football players with a history of ankle sprains reduced their risk of reinjury by 77% by training with the More >

First Step to Active Health® effective for both group- and home-based programs
Aug 11th
Michael Rogers, PhD of Wichita State University, discussed 2 studies on the Thera-Band® First Step to Active Health® recently presented at the American College of Sports Medicine. Working with researchers from Nagoya City University in Japan, Rogers investigated the effects of 12 weeks of the First Step program on functional fitness in older adults. They found significant improvements in function and balance, as well as increased overall physical activity after the program. In addition, the researchers found that the program was successful when performed supervised in a group or unsupervised at home. “The First Step program is a highly effective program for either home or group based exercise in older adults. Our next step is to evaluate the impact of Internet-based feedback on the program,” said Rogers. Dr. Rogers presented his findings at the TRAC 2009 meeting in Cancun, Mexico.
