Background and objective :

TrP-DN plus proprioceptive/strengthening exercises experienced greater improvements in function and pain than those receiving the exercise program alone.


Inclusive criteria :

(1) age between 18 and 50 years, (2) history of at least one ankle sprain, (3) at least one episode of giving away in the previous 6 months, (4) ankle pain of intensity > 3 points on an 11-point numerical pain rate scale (NPRS), and (5) score of 25 or less on the Cumberland Ankle Instability Tool [18, 19]. In addition, participants also had to be physically active, defined as participating in vigorous physical activity at least 20 min a day, 3 times a week [20]. Participants were allowed to continue their regular physical activities during the study period.

Limitation of study:

(1) fracture in the lower extremity, (2) history of surgery in the lower extremity, (3) any concomitant lower extremity pathology, for example, vascular disease and osteoarthritis, (4) pregnancy, (5) regular use of medication, or (6) previous physical therapy interventions received on the lower extremity within the previous 6 months.


This study provides evidence that the inclusion of TrP-DN within the lateral peroneus muscle into a proprioceptive/strengthening exercise program resulted in better outcomes in pain and function 1 month after the therapy in ankle instability.
