There is no single answer for every device and every person. Assistance can change the work your muscles do during an activity. That is different from showing that regular use causes muscle loss, prevents it, or creates physical dependence.
Questions worth taking to a trial
- What activity do I want help with, and what must I still do myself?
- Can I adjust the assistance, and what happens when it stops?
- Does the device make an activity practical enough that I would choose to do it?
- How would this fit with the exercise I already do?
If you have concerns about changing strength, balance or a health condition, discuss your own circumstances with a qualified clinician. Product information cannot determine medical suitability.
Research and limits of the evidence
Less effort during a walk is a short-term result
An exoskeleton supplies mechanical assistance. Depending on the device, its settings and the task, that can reduce demand on some muscles or change when they work. Other muscles still have work to do. The device also adds weight and changes how forces reach your body.
A small laboratory study of a hip-flexion exosuit found lower walking energy cost with optimized assistance. It studied an immediate response in a specific system and group, not years of use of the consumer devices in this catalog. Kim and colleagues, Scientific Reports, 2022.
Muscle activity is not a strength test
Electromyography, or EMG, records electrical activity associated with muscle activation. A lower signal during an assisted step is not a measurement of muscle shrinkage.
A methodological article explains why a brief EMG measurement has not been validated as a predictor of later muscle growth. The same caution matters when someone uses an acute reduction to claim future muscle loss. Vigotsky and colleagues, Sports Medicine, 2022.
Your activity over time matters
Exercise dosage includes how often you move, for how long and how hard the work is. Assistance might change any of those. A person could use it to do activities they otherwise avoid, or use it during activity they already do. Those are possibilities, not evidence that either pattern will improve or weaken their muscles.
Walking assistance and strength training serve different purposes. Public physical-activity guidance includes muscle-strengthening activity alongside aerobic activity. A device is not a substitute for an appropriate exercise plan. U.S. physical-activity guidance.
What would answer the long-term question?
We would need repeated measurements of strength and function, suitable comparison groups, documented device use and a clear picture of participants’ other activity. Results would need to identify the device, assistance settings and population. Findings from one system or clinical population may not transfer to another.
CAPABL has not published long-term strength or dependence results. This is a focused explanation of evidence limits, not a systematic literature review. It does not establish that consumer exoskeletons cause or prevent muscle loss.
