United States, 27th Jun 2025, – As of June, 2025, users are praising ProtoArc’s EM11 NL vertical mouse for alleviating discomfort from RSI and similar conditions. The ergonomically designed mouse encourages a natural hand position to help reduce wrist and forearm strain during repetitive tasks.

RSI: Neglected Office Illnesses

A 2021 report from the National Center for Health Statistics found that 9% of Americans had recently experienced RSI. Primary causes include repetitive motions and poor workplace posture. As keyboard/mouse usage grows, RSI prevalence is expected to rise.

Do ergonomic mice really work? What‘s ProtoArc’s solution?

Research shows ergonomic equipment effectively reduces RSI and musculoskeletal discomfort by modifying workspaces (Refs. 1-3). Consequently, ergonomic interventions remain the most prevalent solution for preventing and mitigating RSI discomfort* (Ref. 4).

ProtoArc alleviates RSI-related pain through ergonomic design—like the EM11 NL mouse—which optimizes muscle engagement and prevents the unnatural twisting of the wrist and forearm.

ProtoArc also provides targeted relief by offering solutions for specific user needs, such as the left-handed EM13 and trackball-equipped EM05 NL.

How is the EM11 NL different from other mice?

Beyond basic vertical designs, the EM11 NL offers targeted comfort for RSI users.

Natural 58° Tilt: Reduces wrist strain vs. extreme angles.

Triple DPI Presets (1000/1600/2400): Minimizes forceful movements via cursor speed adaptation.

Seamless Triple Connectivity (2.4G + 2 Bluetooth): Eliminates device-switching strain.

Supportive Contour & Near-Zero Learning Curve: Ensures immediate, exceptional daily comfort.

User Testimonials: Verified Endorsements

EM11 NL user reviews show ProtoArc’s effective ergonomic solutions. Real user feedback on Reddit, Amazon, and YouTube consistently highlights benefits like: “The shape supports the hand really well”, “I can’t imagine how something could fit more comfortably” and “now I find it much more comfortable especially in terms of wrist and shoulder strain”.

These insights directly inform ProtoArc’s ongoing mission to create peripherals better suited for extended office use.

Upgrade your health strategy

Preventing pain costs far less than treating it. For individuals experiencing or seeking to prevent RSI-related symptoms, products from ProtoArc, backed by multi-year research in ergonomic design, are valuable options.
