A dancer complains having difficulty getting into pointe position on her left foot.
She presents with a more muscular on the left thigh and weakness/ instability on left pointe position. She had a history of a minor ankle sprain in a year ago. There was no pain.
On examination, we discovered that,
Her ankle structure and mobility are satisfactory; however, the mid-foot supination ability is compromised with locking in the cuboid. With her cuboid being immobile, the form closure of the foot was incomplete during pointe, which means she needs extra support from the muscles to complete the stance.
In triple extension, it is obvious that her ankle part does not reach full planter flexion in high speed, which indicates that the soft tissue length is compromised, limiting her joint motion range.
For the pre and post-treatment, neuromuscular training focused on knee-ankle communication was recommended.
Because it is a “closed kinetic chain”, foot mobility should be evaluated when ankle motion is limited.
Joint coupling and soft tissue length should be restored in order to allow full function of the limbs.
“Form closure” is a key for stability, or else “force closure” will have to contribute excessively, leading to early fatigue and injury.
一位舞者抱怨她的左腳在進入足尖站立姿勢時會遇到困難。 她目前呈現了左大腿肌肉較發達、左足尖站立姿勢無力或不穩定的情況。她在一年前曾有踝關節輕微扭傷的病史，但並沒有感到痛楚。 經過檢查，我們發現，
