Shallow men believe in luck. Strong men believe in cause and effect.

We evaluated the gait ability of a stroke patient on the fourth floor in charge of Yamamoto-kun.
We measured the electromyogram of  medial gastrocnemius and lateral gastrocnemius muscle.
This is a scene walking with ankle foot orthosis.


This patient continually uses the gait assisting robot.
As with the evaluation conducted last week, gait speed was improved by wearing a robot, and the amount of activity of the gastrocnemius increased.
What is worrisome is that the amount of activity of the gastrocnemius muscle at loading response is increasing.
Probably, as a result of encouraging strong impact at loading response accompanying the improvement of gait speed, I think that the co-contraction of the tibialis anterior and gastrocnemius muscle was induced.
Although this is not a preferable phenomenon, since the gait speed is improving and the plantar flexion movement of the ankle is also strengthened, I believe that at present it is a good training to wear a robot.


さて、明日はお昼休みの因果推論勉強会・第2回。
今回は「チョコレート消費量とノーベル賞受賞者数は相関関係にある」ってお話。
ソースは2012年にNEJMに掲載された論文。
上の図はその論文のグラフ。


これ、面白い話なので、結構話題になったらしい。
例えばこれはAFP通信のwebサイト。
チョコ消費量とノーベル賞受賞者数には密接で顕著な相関関係がある、と報道しています。

実際に論文の結語にも、

Chocolate consumption enhances cognitive function, which is a sine qua non for winning the Nobel Prize, and it closely correlates with the number of Nobel laureates in each country.
（チョコレートの消費量はノーベル賞を受賞するうえで必須であるとされる認知機能を増強し、その消費量は各国のノーベル賞受賞者数と密接な関連があります。）
って書いてある。

でも大事なことは、その次の文章。
 It remains to be determined whether the consumption of chocolate is the underlying mechanism for the observed association with improved cognitive function.

…そんな話を明日はします。
