Thera-Band exercise program can improve lower limb biomechanics in females

Female athletes are particularly susceptible to anterior knee pain and injury to their anterior cruciate ligament (ACL). This increased risk is thought to result from poor dynamic control of the hip and knee, particularly when the foot hits the ground. The inability to control hip adduction, knee valgus, and internal rotation in the transition from an open- to closed-chain position of the leg may result from weakness of the hip abductor and external rotator muscles.
Researchers have suggested that females have weakness of their hip abductors, extensors, and external rotators (Prins et al. 2009). Exercise programs using Thera-Band® elastic resistance for females with anterior knee pain have been successful and featured previously in the Academy blog. These programs include core stabilization, as well as hip and knee strengthening exercises.
In the January 2012 journal, Medicine and Science in Sports and Exercise, Brazilian researchers published a study of 28 healthy female athletes. They wanted to determine if their exercise program could improve lower limb biomechanics, which theoretically may help reduce injuries. The subjects were assigned to either an 8 week training group or non-exercising control group.

Thera-Band exercise program helps reduce knee pain
Jul 3rd
Patellofemoral pain syndrome results in chronic anterior knee pain, and is often associated with delayed and reduced activation of the vastus medialis oblique (VMO) muscle. Therapeutic exercise is often prescribed to help improve the strength and onset timing of the VMO. Patellar taping is also used in managing anterior knee pain, and is often worn by the patient throughout the day.
Researchers in Turkey wanted to see if an exercise program for patients with patellofemoral pain syndrome could be effective with shorter tape application times (tape worn only during exercise sessions versus worn all day long). First, they compared the VMO muscle activation of 12 men with patellofemoral pain syndrome to 16 healthy controls. The patient group had significantly slower activation of the VMO compared to the control group, as well as significantly reduced strength and activation levels of the affected side compared to the unaffected side.
The 3 month home exercise program for patellofemoral pain syndrome used patellar taping only while exercises were performed, 3 times per day for 30 minutes per session. The progressive exercise program used Thera-Band® Exercise Bands and Stability Trainers. After the exercise program, the patellofemoral patients normalized their VMO activation timing and strength to symmetrical levels that were the same More >
Elastic resistance training can be effective for treating anterior knee pain
Apr 19th
Elastic resistance is often prescribed as part of a rehabilitation program for anterior knee pain (patellofemoral pain syndrome), but its overall efficacy remains unclear. I recently published a systematic review of the topic in the journal, Sports Health. Eight studies using elastic resistance training met the criteria for the review. The exercises typically involved strengthening the hip muscles with 4-direction Thera-Band® kicks, but each study used a different exercise program with elastic resistance. Download an anterior knee pain exercise program with Thera-Band® elastic resistance here.
While each study found significant improvements in pain, due to the study designs (lack of true control), it’s difficult to determine if the elastic resistance was the primary factor for the reduction in pain. However, we can conclude that exercise programs utilizing Thera-Band elastic resistance products can help reduce pain and increase function and strength in patients with patellofemoral pain syndrome.

Home exercise with Thera-Band® tubing reduces knee pain in older Japanese women
Oct 19th
It’s been suggested that 25% of people over the age of 25 experience persistent knee pain (Peat et al. 2001); furthermore, it’s estimated that one quarter of adults with mild to moderate knee pain will develop severe or disabling pain within 3 years (Jinks et al. 2008). Several studies have shown that exercises with elastic resistance such as Thera-Band® resistance bands reduce pain and improve function in patients with knee osteoarthritis (O’Reilly et al. 1999, Topp et al. 2002). Researchers in Japan investigated the effectiveness of home physical therapy exercises in community-dwelling females with mild knee pain.
42 elderly females with mild knee pain during activity were divided into 2 groups based on their home location (thus they were not randomized): non-exercising control group and a home exercise group. Each subject in the exercise group received 2 home visits by a physical therapist for instruction in an exercise program using Thera-Band resistance tubing for leg strengthening. Exercises were progressed as limited by pain and performed 3 times per week for 5 months.
After the program, the individuals in the exercise group significantly improved in their WOMAC score, which measures pain, stiffness and function in arthritis patients. In addition, they had less pain during More >
Thera-Band® exercise program for total knee replacement featured in Lower Extremity Review
Jun 15th
Ongoing research at the University of Louisville and Bellarmine University is investigating the effectiveness of Thera-Band® resistance band exercises before surgery for total knee arthroplasty (TKA). “Prehabilitation” consists of pre-operative exercises that are meant to improve strength and functional levels before surgery with the expectation of better rehabilitation and a faster recovery after surgery.
The TKA Prehab Program was recently featured in an article in the March 2010 edition of Lower Extremity Review. The program utilizes Thera-Band resistance bands, step-up exercises, and stretching exercises. A full-color printable handout of the program is available online.
