The ekrin b37 for court reporters delivers targeted relief from stenotype finger fatigue and forearm soreness without the bulk or noise of a full-size percussion gun. After eight hours of writing depositions, your flexor tendons, lumbricals, and forearm extensors lock up in patterns ordinary stretching cannot reach. The B37's 12mm amplitude, 56 lb stall force, and palm-friendly 1.5 lb body let you self-treat trigger points in the thenar pad, pronator teres, and brachioradialis between transcripts. Below we explain why this model fits stenographers specifically in 2026, then compare five worthwhile percussion devices that also serve hands and forearms when the B37 is out of stock or out of budget.
Why stenotype work destroys hands and forearms
A working court reporter strokes 225 to 300+ words per minute across a 24-key keyboard, holding the wrists in slight ulnar deviation and the fingers in sustained flexion. Over a full trial day, that produces roughly 90,000 to 150,000 finger contractions, most of them happening in the deep flexors of the forearm rather than in the fingers themselves. The cumulative load creates four predictable problem zones: the medial epicondyle (golfer's elbow territory), the belly of the flexor digitorum profundus mid-forearm, the pronator teres just below the elbow crease, and the small intrinsic muscles of the palm between the metacarpals.

Cold conference rooms, raised platforms with no armrest, and back-to-back depositions compound the issue. Many reporters report waking at 3 a.m. with numb ring and pinky fingers (ulnar nerve compression), or a burning sensation along the thumb side of the wrist (de Quervain-style irritation of the abductor pollicis longus). Percussion therapy will not cure nerve entrapment, but it can interrupt the trigger-point feedback loop that keeps the forearm hypertonic between sessions, restoring some of the elastic recoil that makes the next morning's writing feel light again. For context on the broader recovery toolkit, see our percussion therapy for repetitive strain primer.
What makes the Ekrin B37 the right fit for court reporters
The B37 is Ekrin's mid-size model, and it hits a sweet spot stenographers care about. First, the angled handle reduces wrist deviation when you treat your own forearm — critical because forcing a straight-handled gun onto your dominant arm with the non-dominant hand often reproduces the very strain you are trying to resolve. Second, the stall force tops out around 56 lb, meaning you can press into a stubborn pronator knot without the motor stuttering, but the lowest of its five speeds (around 1400 rpm) is gentle enough for the palmar arches. Third, the amplitude is 12mm — long enough to reach the deep flexor compartment, short enough that you are not jackhammering the radial nerve at the wrist.
Battery life lands at roughly six hours per charge, which matters because hotel rooms during travel trials rarely have a convenient outlet at the desk. The carry case fits in a standard briefcase next to the realtime laptop, and the unit runs at about 45 dB on speed one — quiet enough to use during a recess in the witness room without drawing attention. The flat head handles the forearm bellies, the bullet head reaches the pronator teres and the first dorsal interosseous between thumb and index, and the soft round head is the everyday choice for the palm and the lumbricals.

RENPHO Active Thermacool 2 — best heat-and-cold alternative to the Ekrin B37 for court reporters
When the flexor tendons at the medial epicondyle are inflamed from a week of expedited transcripts, you want cold therapy before percussion and heat after. The Thermacool 2 packages both into a single attachment, which means you skip the gel pack and the microwaved rice sock you used to juggle. Reporters who already own a basic massager often add this as a second device for the elbow specifically. The handle is slightly bulkier than the B37, but the contrast therapy head is genuinely useful for de Quervain irritation along the radial styloid. Check the RENPHO Thermacool 2 on Amazon.
TOLOCO EM26 — best budget percussion gun for new reporters
If you just passed the RPR exam and the B37's price tag is a stretch, the TOLOCO EM26 is the honest answer. It runs louder and weighs more, but the 12mm amplitude and 10-head kit give you the same anatomical reach. Use the bullet head sparingly on the pronator teres (10 seconds at most), and rely on the flat head for the wrist extensors. It will not last a decade like the B37, but it will get a busy freelancer through a year of daily depositions while you save for a premium upgrade. View the TOLOCO EM26 on Amazon.
Medcursor High-Intensity Brushless — best for reporters who treat themselves daily
Brushless motors matter when you run the device every workday. Brushed motors degrade over roughly 800 to 1,200 hours of use; brushless designs typically triple that lifespan. Medcursor's high-intensity model keeps weight reasonable while giving you the percussive depth needed to reach the deep flexor compartment, the spot most reporters cannot touch with foam rollers or massage balls. The included heads cover the forearm well, though you may want to add a third-party fingertip attachment for the lumbricals. See the Medcursor brushless gun on Amazon.
NAPRE Heat and Cold — best for acute flare-ups during trial week
Long trials produce predictable Wednesday-night crashes: the wrist swells, the thumb won't oppose smoothly, and the morning's first stroke feels like sandpaper. The NAPRE's cold head, set to its lowest temperature, calms the radial-side soft tissue before you even start percussion, then you flip to the heat head for the forearm bellies. This is not your everyday driver, but as the secondary device for trial weeks it earns its drawer space. Check the NAPRE on Amazon.
AERLANG Heated Massage Gun — best for cold conference rooms
Federal courthouses tend to over-air-condition. By 2 p.m. your forearms are 8 degrees cooler than your core, and cold muscle is stiff muscle. The AERLANG's heated head warms tissue while you percuss it, mimicking the effect of a moist heat pack without the setup. It is bulkier than the B37 and not as travel-friendly, but if you mostly work from a fixed home office or one regular courthouse, it removes a step from your warm-up routine. View the AERLANG on Amazon.
A 90-second routine to use between depositions
Speed setting 1 or 2, soft round head. Start at the belly of the forearm flexors, mid-way between elbow and wrist, palm facing up. Glide slowly toward the elbow for 20 seconds per arm — never park the head on one spot for more than 5 seconds. Flip to palm-down and repeat on the extensor side. Switch to the bullet head and tap (do not press) the pronator teres for 10 seconds. Finish on the palm itself with the soft head, working between the metacarpals. Total: 90 seconds per arm. Do not percuss directly over the wrist crease, the elbow's funny-bone groove, or any visibly swollen joint. For a longer post-shift sequence, see our forearm recovery routine for keyboard professionals.
Frequently Asked Questions
Is the Ekrin B37 too powerful for stenographer hands?
No, because the B37 has five speeds and the lowest is gentle enough for palm work. The risk with any percussion gun on hands is duration and pressure, not peak power. Keep contact light, never hold the head on bone, and limit each spot to five seconds. The 12mm amplitude is what reaches the deep flexor compartment in the forearm; the lower amplitudes on pocket-size guns often cannot.

Can a massage gun help with carpal tunnel from stenography?
Percussion therapy does not treat carpal tunnel syndrome at the carpal tunnel itself — never percuss over the median nerve at the wrist. It can reduce upstream muscle tension in the pronator teres and flexor digitorum that often contributes to median nerve irritation along its path. If you have numbness, tingling, or weakness, see a hand specialist; percussion is an adjunct to medical care, not a replacement.
How often should a court reporter use a percussion gun?
Most reporters do well with two short sessions per workday: a 90-second wake-up before the first deposition and a 3-minute decompression at end of day. Add a longer 5-minute session on trial weekends when symptoms are higher. Daily use is fine if you stay on lower speeds and avoid bony landmarks. Overuse signs include bruising, increased numbness, or morning stiffness that worsens rather than improves.
What attachments matter most for stenotype forearm fatigue?
Three heads do 95% of the work: the soft round head for palms and lumbricals, the flat head for forearm bellies, and the bullet head used sparingly on the pronator teres. Heated and cold heads are useful add-ons for elbow tendinopathy. Fork heads are not necessary for hand work — they were designed for the spine.
Will my law firm or court accept the noise of a massage gun in the witness room?
The Ekrin B37 runs at roughly 45 dB on its lowest setting, quieter than typical office HVAC. It is appropriate for use during recesses in a private witness or reporter room. Avoid use in the courtroom itself or anywhere the record is being made. Budget models like the TOLOCO run closer to 55-60 dB and are better saved for the parking lot or your car between locations.
Should I use heat or cold before percussion on a sore forearm?
Cold first if the soreness is sharp, recent (within 24 hours), or accompanied by swelling — 60 to 90 seconds of contact with a cold head calms the area enough for percussion to feel productive rather than painful. Heat first if the soreness is dull, chronic, or stiffness-dominant. The RENPHO Thermacool 2 and NAPRE make this routine one-handed; otherwise a gel pack from the freezer works.
Is the Ekrin B37 worth it compared to a $60 Amazon gun?
For an occasional user, no — a budget gun delivers 70% of the benefit. For a working court reporter who will use the device 200+ days per year, yes. The angled handle reduces self-treatment strain, the lower noise floor lets you use it in professional environments, the battery survives multi-day travel, and the brushless motor lasts long enough to amortize the price. The B37 is a tool that pays for itself in fewer pain days off the job.
