Arresting someone who has one arm follows the same legal rules as any other arrest, but the officer has to adapt the physical parts of the process. Federal disability law requires police to modify standard procedures when a person’s body doesn’t fit them, and standard arrest procedure assumes two wrists. In practice, that means a different way of taking hold of the person, a different way of putting them in restraints, and closer attention to injury risks that don’t come up with a two-armed subject.
Why the Procedure Has to Change
Title II of the Americans with Disabilities Act prohibits public entities, police departments included, from discriminating against people with disabilities.1Office of the Law Revision Counsel. 42 USC 12132 The Department of Justice reads that to require reasonable modifications to policies and procedures during law enforcement encounters, unless the change would fundamentally alter the service. DOJ guidance uses handcuffing as its example: departments should modify the default practice of cuffing behind the back when that approach doesn’t work for a person’s disability, and officers are expected to ask the person how best to assist them rather than default to the standard technique.2U.S. Department of Justice.

The constitutional side layers on top. Every arrest is measured by the Fourth Amendment’s “objectively reasonable” standard from Graham v. Connor, which weighs the seriousness of the offense, the immediate threat, and whether the person is resisting or fleeing.3Library of Congress. Graham v. Connor, 490 U.S. 386 (1989) A visible amputation doesn’t change the standard, but it changes what a reasonable officer does. Treating a cooperative one-armed person the same as a two-armed person actively fighting is hard to defend.
Sizing Up Before Making Contact
Good practice starts before anyone touches anyone. The officer notes what they can see, including whether the person has a limb difference or wears a prosthetic, and adjusts commands accordingly. An instruction like “show me your hands” makes no sense to someone with one hand; “put your hand where I can see it” does.
If a prosthetic is visible, officers can ask about it. Useful questions cover what type of device it is, where it attaches, whether it’s mechanized, and whether there are movement limitations that could cause injury during a search or restraint. A hook attachment presents different safety considerations than a cosmetic prosthesis, and officers plan the next steps around the answer. The ADA lets officers ask about the device and how it functions, but not for a diagnosis.2U.S. Department of Justice. Commonly Asked Questions About the ADA and Law Enforcement
Physical Control With One Arm
When verbal commands aren’t enough and physical control becomes necessary, officers use what training materials call empty-hand control: grabs, holds, and joint locks at the lower end, escalating only as resistance escalates.4National Institute of Justice. The Use-of-Force Continuum For a one-armed subject, the standard two-wrist techniques don’t apply, and officers typically adapt in three ways.
Control shifts to a single-arm hold. Instead of gripping two wrists, the officer secures the available arm and uses their own body positioning against the person’s torso and shoulder or waist to manage balance. Balance itself changes with one arm. A person with only one arm braces and rights themselves differently, so a competent officer both uses that when guiding the person to a controlled position and accounts for the increased fall risk that comes with it. The residual limb, if there is one, is not grabbed, twisted, or used as a control point; doing so creates real injury risk and gives the officer little leverage anyway.
Proportionality is the through-line. A person with one arm has roughly half the upper-body capacity to resist compared with a two-armed person, and force that ignores that asymmetry is where excessive-force liability starts.
How Officers Handcuff Someone With One Arm
Standard handcuffs are built for two wrists. Departments handle the mismatch in a few ways, and the specific choice depends on policy, anatomy, and what equipment the officer is carrying.
- Single cuff to a fixed point on the body. One cuff goes on the available wrist and the other attaches to the person’s belt, a belt loop, or the waistband. This is the most commonly described field adaptation and keeps the hand secured close to the body.
- Flex cuffs. These are heavy-duty nylon restraints with a dual-loop design that adjusts to different circumferences, which gives officers flexibility when metal cuffs don’t fit the situation.
- Transport belt or belly chain. A belt worn around the waist with an attachment point for the wrist secures the person for longer transport without needing a second wrist. Some departments carry these specifically for situations where standard cuffs won’t work.
Whichever method the officer uses, handcuffs should be double-locked so they can’t ratchet tighter, and the fit should be checked. The ADA’s reasonable-modification requirement reinforces the point: standard booking procedures that assume two wrists have to be adapted, not forced.2U.S. Department of Justice.

Injury Risks the Officer Has to Watch
Handcuff injuries are a documented medical concern in ordinary arrests. Cuffs compress the peripheral nerves at the wrist, and the radial nerve sits close to the surface and is especially vulnerable. Injuries to the median or ulnar nerves can cause significant disability and sometimes require rehabilitation to resolve.5PubMed. Handcuff Neuropathy – Two Unusual Cases
Those risks concentrate when someone has only one arm. All the restraint pressure sits on a single wrist rather than being spread across two, which raises the odds of nerve compression and circulation problems. If a cuff is attached to a residual limb, the tissue there is often more sensitive and less padded than an intact wrist, and injury is more likely. Officers who understand this check cuff tightness more often and use the loosest effective fit.
When the Force Used Was Too Much
Someone who believes the force used during their arrest was disproportionate to their disability generally has two possible claims. The first is a Fourth Amendment excessive-force claim under 42 U.S.C. ยง 1983, measured against the Graham reasonableness standard.3Library of Congress. Graham v. Connor, 490 U.S. 386 (1989) The second is an ADA Title II discrimination claim based on the agency’s failure to make reasonable modifications during the encounter.1Office of the Law Revision Counsel. 42 USC 12132 The Supreme Court’s 2025 decision in Barnes v. Felix clarified that courts must consider the full sequence of circumstances leading up to the use of force, not just the split-second contact, which matters in disability cases where an officer’s failure to adapt earlier in the encounter often sets up the confrontation.
The practical steps after an arrest that went wrong are the same ones that strengthen any use-of-force complaint: request medical attention on the scene, document injuries as soon as possible, and record the names and badge numbers of the officers involved.
