Stitch 1
AI movement

AI movement evaluation:
72%
Personalized suggestions based on Stitch duration, Needle holder trajectory length
and Sudden moves count
Try to make your movements more smooth and precise. The stitch duration is too long.
Try to keep your instruments closer to the incision to avoid unnecessary large movements. The needle holder visibility is too low. The forceps visibility in area around stitch is too low.
Stitch duration [s]
The dotted line represents your time for the stitch being
analyzed. If the line is green (below 60 seconds), your time is
good. If it is yellow (between 60 and 90 seconds), your time is
acceptable. If it is red (above 90 seconds), your time is too
slow.
The red graph below represents the distribution of time needed
by experts for one stitch.
The red histogram shows the number of stitches performed by
experts that took the given time indicated on the x-axis.
The blue graph represents the distribution of time needed by
learners.
The blue histogram shows the number of stitches performed by
learners that took the given time indicated on the x-axis.
If your time is significantly higher than the expert times,
consider what may have caused the delay:
Did you successfully hit the skin penetration point on
the first attempt? If not, try focusing on the target
point with your eye before starting the movement.
Was the needle easy to pass through? If not, check
whether it was correctly positioned in the needle
holder.
Did the needle exit on the intended incision plane on
the first attempt? If not, ensure you visually align
with the desired exit point before starting the motion.
Moderate
Observation: Your stitch duration is somewhat longer than expert-level timing, placing you in the yellow performance range.
Recommendation: Aim to refine your technique and decision-making to improve efficiency. Regular practice on simulation models can help develop muscle memory and enhance your speed.
Needle holder path length
Appropriate
Observation: The path length of your needle holder is very similar to expert-level performance and falls within the green zone.
Recommendation: Keep practicing to maintain this level of control. Concentrate on repeating this movement length consistently to support reliable performance.
Needle holder jerk index
Appropriate
Observation: The number of sudden or abrupt needle holder movements is similar to expert-level performance and falls within the green zone.
Recommendation: Keep practicing to sustain this balance of speed and control. Aim to consistently reproduce this movement quality to maintain precision and efficiency.
Needle holder movement heatmap
The heat map represents the projection of the needle holder movement
during the process of stitching on the pig foot
Above 85% frequency is considered optimal (green).
Between 70% and 85% is considered acceptable but could be
improved (yellow).
Below 70% is considered not ideal (red).
If your needle holder positioning differs significantly from expert
patterns, consider working on these:
Ensure that the needle holder remains close to the incision
to maintain control and precision.
Avoid excessive movement or unnecessary repositioning to
improve efficiency and consistency.
Practice smooth and controlled handling to keep the needle
holder within the optimal range (green circle) throughout
the stitching process.

Moderate
Observation: Your stitch time is a bit longer than the expert’s, but still falls within the yellow zone.
Recommendation: Work on making your movements more efficient and decisive. Practicing on simulation materials can help you build muscle memory and improve your speed.
Needle holder path length
Appropriate
Observation: The distance your needle holder travels closely matches expert-level performance and falls within the green zone.
Recommendation: Keep practicing to preserve this level of efficiency. Concentrate on consistently reproducing this movement range to maintain precision and control.
Needle holder jerk index
Appropriate
Observation: The count of the needle holder’s sudden movements is close to the expert level, within the green zone.
Recommendation: Continue practicing to maintain this level of speed and control. Focus on replicating this velocity to ensure consistent performance.
