| Abstract |
Our purpose was to quantify the effects of head pitch on muscle activity patterns of the decerebrate cat hindlimb during walking. Five decerebrate cats walked at 0.7 m/s on a treadmill positioned level with the head pitch either parallel to the treadmill, 50% nose down or 50% nose up. We collected electromyography data from six hindlimb muscles. During level walking, after we manipulated head pitch, our results were surprisingly equivalent to the research on slope walking. For instance, muscle activity during level walking with a 50% head pitch nose down mimicked uphill walking. The muscle activity of the iliopsoas and semitendinosus significantly increased. Muscle activity during level walking with a 50% head pitch nose up mimicked downhill walking. Specifically, the biceps femoris and semimembranosus were inactive during the entire step. These alterations in muscle activity occurred within one step of altering head pitch but dissipated as level walking continued. In conclusion, the time course of muscle activity patterns due to modifications in head pitch is immediate and transitory. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 March 2011.
All research outputs
#7,415,394
of 22,673,450 outputs
Outputs from Experimental Brain Research
#900
of 3,217 outputs
Outputs of similar age
#24,321
of 67,134 outputs
Outputs of similar age from Experimental Brain Research
#7
of 17 outputs
Altmetric has tracked 22,673,450 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,217 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.0. This one has gotten more attention than average, scoring higher than 55% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 67,134 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
