“Wall slides” is an incomplete exercise instruction. It can describe facing a wall and sliding a hand upwards, resting the forearms against it, or standing with your back to it. These are not interchangeable. Before trying to copy a video, match the starting position to the movement your therapist demonstrated.
Facing the wall with a towel
Cambridge University Hospitals includes a towel-assisted wall slide in its advice after shoulder hydrodistension. In that version, the hand rests on a towel against the wall and slides upwards as the person steps closer, then returns as they step back. That leaflet describes a particular treatment context. Its repetition schedule should not become a default prescription for every painful shoulder.
A useful check is to describe the exercise back to your therapist: which hand touches the wall, whether the elbow starts bent, and whether you step towards the wall. If the answer differs from the video you found, use the demonstration given for your own plan.
Height is not the only thing to watch
- Keep the movement within the range you were shown. Reaching the highest mark on the wall is not the goal of every session.
- Notice whether you are leaning or arching to make the hand travel farther. Mention that change when asking for a technique check.
- Use a surface that allows the prescribed slide without a sudden catch. Move nearby objects out of the way.
- Include the lowering phase in your practice. Ask for help if returning the arm is harder than raising it.
Do not borrow a progression from another version
Adding a band around the wrists, lifting the hands away from the wall, or turning sideways changes the exercise. A movement prescribed to practise reaching may not have the same aim as a strengthening drill. Ask which change comes next and what your therapist wants you to observe before making it.
A simple note can make the next review more productive: “The hand moved smoothly to shoulder height, but I leaned backwards above that point.” Include whether the issue happened immediately or only near the end of the set. This gives more context than a photo of your highest reach.

Fit the exercise around daily activities
Tell your therapist which real movement is difficult, such as reaching a shelf or putting on a coat. Ask how the wall slide relates to that task and how progress will be checked. A change in wall-slide height alone does not establish that every overhead activity is ready to resume.
After a shoulder operation or dislocation, follow your treating team’s movement restrictions. Stop and seek advice for new sharp pain, weakness or persistent tingling; sudden severe pain or inability to move the arm needs urgent assessment.
