Clear scans do not always equate to normal function.
When a client presents with persistent joint restriction and pain following an injury, standard approaches often focus heavily on structural tissue deficits or local weakness. But what happens when standard care plateaus?
In many chronic cases, the limitation isn't structural failure—it is a coordination strategy. The nervous system intentionally implements Arthrogenic Muscle Inhibition (AMI) to lock down the joint, altering how it allocates resources under load.
To truly understand the presentation, we must look past static posture and analyze dynamic neuromuscular control.
Here is a de-identified look at how a complex presentation reorganized over four clinical sessions, utilizing VALD ForceDecks dual force plate technology to track the transition from neural inhibition to consolidated movement efficiency:
• Squat Depth: Transitioned from a restricted baseline average of 21.8 cm to 38.9 cm.
• Average Peak Force: Changed from 702 N to 872 N.
• Eccentric Braking (RFD): Developed from a chaotic 126 N/s to an organised 628 N/s.
• Neuromotor Consistency: Braking Rate of Force Development variance (CoV) reduced from an unstable 877% down to 29%.
These biometrics do not simply reflect a sudden gain in muscular strength. They demonstrate a nervous system clearing a protective inhibitory pattern and reorganising its movement strategy.
However, introducing a +10 kg external load exposed the next layer of the compensation puzzle. While her peak force remained robust and depth was consistent, the load immediately highlighted a significant eccentric braking asymmetry. The system was reorganising, but it was not yet fully stable under higher demands.
This underscores a vital clinical progression:
1. Alleviating pain is one step.
2. Restoring movement quality is another step.
3. Consolidating that quality under load is another step entirely.
In complex, post-injury cases, we must look beyond the structural imaging. The definitive question is often: "Why is the nervous system preventing access to a movement strategy the body already knows how to execute?"
Dynamic force plate assessment allows us to bridge the gap between clear scans and real-world functional capacity.
