There is a particular kind of wrist pain that makes ordinary movements suddenly feel uncertain.
Turning a key. Opening a jar. Holding a heavy object. Pushing up from a chair. Sometimes the pain is sharp and localised to the little-finger side of the wrist, sometimes it feels more like irritation, weakness, or a sense that something is not quite stable.
This is where kinesiology tape may have a role.
In physiotherapy, taping is usually not considered a treatment on its own. It is a temporary support tool that can be used alongside load management, exercise, movement retraining, and other parts of rehabilitation.
For people experiencing ulnar-sided wrist pain, including symptoms associated with the triangular fibrocartilage complex (TFCC) or irritation of the extensor carpi ulnaris (ECU) tendon, tape may provide a feeling of support during everyday activity.
That feeling matters.
Pain can make a person unconsciously change the way they use the wrist. Grip becomes guarded. Movements become smaller. The hand starts working around the painful area rather than through it. A temporary external cue may sometimes make movement feel more controlled and less threatening.
The purpose is not to force the wrist into a particular position.
It is more about giving the person a little more confidence while the underlying problem is being addressed.
Tape can also be useful during activities that place repeated demands on the wrist, particularly gripping, lifting, sport, or tasks involving repeated forearm and wrist movement. Some people notice reduced discomfort while wearing it. Others notice very little difference.
That variation is normal.
Kinesiology tape does not repair a torn TFCC. It does not heal an injured tendon and it cannot restore an unstable joint by itself. It should not become a reason to keep loading an injured wrist beyond what it can currently tolerate.
Think of it as an accessory to rehabilitation, not the rehabilitation itself.
The technique shown in the video is intended as a practical option for people who may benefit from additional external support around the ulnar side of the wrist. It may be particularly useful when symptoms are aggravated by activity but settle with appropriate rest and load modification.
There is, however, an important limitation.
Pain on the little-finger side of the wrist does not automatically mean TFCC or ECU involvement. Several structures occupy a relatively small area, and their symptoms can overlap. The distal radioulnar joint, tendons, ligaments, and other wrist structures can produce similar complaints.
This is why persistent pain should not simply be taped over.
If wrist pain continues, repeatedly returns, is accompanied by clicking or a feeling of instability, or significantly affects grip and daily function, a clinical assessment is more useful than trying progressively stronger taping techniques.
The tape can make the wrist feel better.
That can be useful.
But the real goal is for the wrist to become capable of doing the work without needing the tape to remind it that it can.
