The "Tightness" Trap Part 2: The Dosing Dilemma
In my last post, we discussed why stretching is often just chasing a sensation, while repeated end-range loading addresses the source.
But there is another critical difference that explains why your patients return week after week with the same "tight" upper traps or hamstrings: Dosing.
If we are going to change how the nervous system governs movement, we have to look at how often we apply the intervention.
1. Stretching: The "Maintenance" Dose
Think about how most patients (and many therapists) utilize stretching. It’s typically prescribed once or twice a day, or perhaps as a quick warm-up before activity.
The Reality: This frequency is barely enough to maintain current extensibility levels, let alone create lasting mechanical change.
The Outcome: It’s a transient neuro-modulatory event. You get a temporary "release" of tone, but the underlying governor of that tension hasn't been reset.
2. Repeated Loading: The "Persuasion" Campaign
Repeated end-range loading (think MDT/McKenzie) is fundamentally different because it’s not about length; it’s about information. End Range Loading in the Directional Preference is key.
The Reality: We don't just do 10 reps once a day. We dose it repeatedly throughout the day.
The "Why": A locked-down area is often the result of a protective nervous system throwing up red lights. You can't convince a terrified nervous system that movement is safe with a single "polite stretch" in the morning.
The Outcome: By repeatedly hitting the directional preference, you are bombarding the CNS with non-threatening input. You are convincing the system, rep by rep, to turn off the threat response and give that area permanent "green lights" for movement.
The Clinical Takeaway
You cannot treat a frequency-dependent problem with a once-a-daily solution.
If you are looking for a temporary window of relief, stretch it once a day.
If you are looking to restore motor control and convince the nervous system to let go of protective tone, you need to dose the directional preference repeatedly until the change sticks.
Dose for the outcome you want.
