Tight isn't always tight

The first thirty seconds of a new appointment almost always contain the same line, in some form: "I'm really tight here." People point at their shoulders, their hamstrings, their lower back. I almost always press on the spot they're pointing at. And very often — not always, but often — what I find is tissue that feels just like the tissue around it. Nothing noticeably tight about it.

This isn't me telling people they're wrong. That feeling of tightness is completely real. But "tight" as a word does two jobs in one breath. It describes a sensation we have — a felt sense of stiffness, heaviness, something-not-quite-right. And it describes a physical state we assume is producing that sensation — muscle that's literally shorter, or more contracted, than its neighbours.

Most of the time, only the first of those is actually true.

Why it matters clinically

If "tight" means "these fibres are mechanically shorter and need lengthening", then the treatment plan is obvious: stretch them. Release them. Hands-on work to lengthen, then exercise to maintain length.

If "tight" is a feeling produced by the nervous system because something — sleep, stress, load, fear of movement, a past injury memory — has that area on alert, then stretching for two weeks won't shift it. What shifts it is input the nervous system reads as safe: gentle movement through range, hands-on work that reduces threat, understanding what's going on, and usually some combination of all three.

Worth sitting with, that one.

How I try to tell the difference

In clinic, I'll look and feel. Does the muscle resist movement through range, or does it move fine but feel horrible? Is it consistently short compared to the other side, or does the felt-tightness shift around? Are there other inputs — sleep gone, training spike, stress spike — that could be turning the volume knob up on that area?

Most of the time we're dealing with both at once: a slightly less pliable muscle and a nervous system that's giving it extra volume. Treatment is both. Hands-on work on the tissue, plus teaching the system this area isn't in danger any more.

What to do with this

If you're coming in for treatment and the first thing you want to say is "my hamstrings are really tight" — please still say that. It's useful clinical information; I just don't treat it as the end of the story. The question I'm trying to answer isn't how do I un-tighten this one muscle? It's why is this person's system producing that feeling, and what inputs can we change?

Sometimes the answer is: yes, this muscle is genuinely short and we need to lengthen it. Sometimes the answer is: sleep is wrecked, training load has doubled in six weeks, and your shoulders are shouting that message the only way they know how.

Knowing which is which is the actual work.
