#Ulnar Deviation

The percentage contribution for ulnar deviation is calculated by dividing an individual muscle’s torque by the sum of all muscles involved. According to the Holzbaur et al. (2005) model, we determine raw force through PCSA (the total area of muscle fibers), which is 2.1 cm^2 for the ECU and a beefier 2.9 cm^2 for the FCU. However, leverage makes a difference. The moment arm is a measure of mechanical advantage measured by tracking how far a tendon moves during rotation (Garland et al. (2018). Because the ECU has a much larger leverage of 23.7 mm compared to the FCU’s 11.7 mm, its calculated torque (49.77) outweighs the FCU’s (33.93), resulting in the ECU providing 59.5% of the total force despite being the smaller muscle. #armwrestling

Tingling in your ring and little finger? That’s your ulnar nerve. It runs behind your elbow through a tight space called the cubital tunnel. Too much bending… leaning… or pressure… = compression. That’s why you feel: ⚡ Tingling ⚡ Numbness ⚡ Weakness Ignoring it makes it worse. You need: ✔️ Less pressure ✔️ Better positioning ✔️ Gentle movement Fix it early.

Tennis elbow and golfers elbow aren’t “old injuries” or something you just need to rest forever. They’re tendon load problems. And tendons don’t heal from rest… they heal from the right kind of stress. • The research is clear: blood flow at high volume, low resistance, isometrics and eccentric work improve tendon structure, strength, and pain tolerance. That’s where the rice bucket comes in. Simple. Cheap. Brutally effective. And most importantly… low resistance so blood flow becomes the key outcome! • A rice bucket trains the forearms through every angle and plane… flexion, extension, rotation, deviation, and grip/squeeze. It’s exactly what most rehab misses and exactly what elbows need to get resilient again. • Rice bucket protocol (do as often as you can tolerate): • Wrist flexion & extension • Radial & ulnar deviation • Pronation & supination (rotation) • Finger open/close • Squeeze, pinch, and twist the rice • 👉 Aim for ~30 reps per movement, controlled tempo. Some discomfort is fine. Sharp pain isn’t. Build capacity, not ego. • This is how you bulletproof your elbows so you can actually train hard again… kettlebells, pull-ups, presses, swings, the lot. • If you want to train from home, protect your joints, and still get jacked and shredded in under 30 minutes, comment FLOW below and I’ll send you my top 30 kettlebell flows 💪

💥ULNAR NERVE ASSESSMENTS💥 ▪️There are a number of places along the length of the ulnar nerve where compression can take place: two of these places are at the cubital tunnel at the elbow and guyons canal at the wrist ▪️Symptoms can include: Pain/Numbness/tingling/Weak grip-pinch/Decreased fine motor coordination ▪️There are many ways to assess for ulnar nerve dysfunction - this is not a comprehensive list! Just a few common ways that I like to start my assessments: PROVOCATIVE TESTS ▪️Elbow flexion test: Full elbow flexion for 60 seconds, (+) test = parasthesias in the forearm/ring and small fingers. 60 seconds might be too long with acute inflammation! ▪️Tinel’s to the cubical tunnel: Tapping the nerve at the elbow under the medial epicondyle, (+) test = parasthesias in the forearm/ring and small fingers. ▪️Tinel’s to Guyons canal at the wrist TESTING THE STRENGTH/WEAKNESS OF ULNAR NERVE INNERVATED MUSCLES: ▪️Resisting wrist flex/ulnar deviation (Flexor Carpi Ulnaris - FCU) ▪️Resisting fingertip flexion of small and ring fingers (Flexor Digitorum Profundus - FDP) ▪️Resisting index finger abduction (1st dorsal interosseous) ▪️Resisting small finger abduction (Abductor Digiti Minimi) ▪️Crossing index over middle fingers (Intrinsics - Interossei) ▪️Resisting lateral pinch (Froments): adductor pollicis strength is tested with lateral pinch on a small piece of paper and watching for thumb IP flexion compensation (if the thumb IP flexes = (+) Froments sign) ▪️Testing the strength/weakness of these muscles can indicate the presence and progression of ulnar nerve dysfunction ‼️Always take an extensive history and standardized sensation measures. These are just some tests to get started - not a comprehensive list‼️ ‼️Also try the scratch collapse test! ‼️Be aware of brachial plexus level involvement (TOS) or ulnar nerve compression at the wrist (Guyon’s) which can mimic some ulnar n. symptoms‼️ #handtherapy #occupationaltherapy #physicaltherapy #physiotherapy #ortho #orthopedics #elbow #cubitaltunnelsyndrome #cubitaltunnel #ulnarnerveentrapment #ulnarnerve #anatomy

✨Ulnar Nerve Actions✨ The ulnar nerve supplies key muscles in the forearm and hand that are essential for power grip, precision movements, and fine motor control: ⚪Wrist flexion + ulnar deviation: Flexor Carpi Ulnaris ⚪DIP flexion of ring & small finger: Flexor Digitorum Profundus 🟡MCP flexion/IP extension of ring & small finger: Lumbricals 3 & 4 🟡Adduction of digits 2, 4, 5: Palmar Interossei (PAD) 🟡Abduction of digits 2, 3, 4: Dorsal Interossei (DAB) The interossei also contribute to MCP flexion and IP flexion of the digits 🟢Abduction of 5th digit: Abductor Digiti Minimi 🟢Flexion of 5th MCP: Flexor Digiti Minimi 🟢Opposition of 5th digit: Opponens Digiti Minimi 🟢Adduction of thumb: Adductor Pollicis 🟢Flexion of thumb MCP: ½ of Flexor Pollicis Brevis 🟢Wrinkling of hypothenar skin: Palmaris Brevis 🎥Cc:. @thehandenthusiast . . . . #emission #emissionphysio #handtherapy #occupationaltherapy #physicaltherapy #physiotherapy #ulnarnerve #anatomy #handanatomy #guyonscanal #cubitaltunnel #neuroanatomy

Ulnar Deviation for Pinky Strength. I know this sounds weird but I’ve completely felt a difference in my crimp strength by isolating my pinky and one of the best ways to do that is by training ulnar deviation strength! Thought some of you would enjoy this. This is actually one of about 6 exercises I did in my recent YouTube video describing my total forearm training 💪 #gripstrength #climbing #rockclimbing #ninjawarrior #armwrestling #crimpstrength #fingertraining #forearmworkout

Forearms sirf wrist curls se nahi bante. Radial aur ulnar deviation jaise small movements se forearms ki depth aur thickness develop hoti hai. Dumbbell ho ya cable, angle sahi rakho aur slow control ke saath movement karo for better forearm growth 💪🔥 #ForearmWorkout #RadialDeviation #UlnarDeviation #GripStrength

📈🔥Grow your forearms using dumbbells only. Control the wrists, feel every rep. 🔥 Train smarter and build stronger arms with @the_brothers_gym007 💪🔥The Best Exercises for Bigger Forearms ➰ Reverse Grip Curls Targets the brachioradialis and upper forearm, helping build thickness and visible arm separation. Use controlled reps and avoid swinging the weight. ➰ Wrist Curls Directly isolates the forearm flexors, building size and grip strength. Focus on a slow stretch at the bottom and a strong squeeze at the top. ➰ Reverse Wrist Curls Emphasizes the forearm extensors for balanced development and healthier elbows. Keep movements short and controlled. ➰ DB Radial & Ulnar Deviation Strengthens wrist stability and trains often-neglected forearm muscles. Use light weight and strict form. ➰ Wrist Rotations Improves endurance, coordination, and overall forearm control. My suggestion: 3–4 sets • 12–20 reps • 2–3 sessions per week 💡 Key tip: Forearms grow best with consistency, volume, and control — not heavy weight. Train smart, stay consistent, and let your forearms finally match your arms. 💪 Best Forearms workout for grow 📈 your arms and strong. ✅ Do THESE To Build BIGGER Forearms To target the inner forearms, do dumbbell wrist curls with a supinated grip (palms up). For the outer forearms, use a pronated grip (palms down) and perform wrist extensions. To emphasize the brachioradialis, try concentration hammer curls with a neutral grip. For the radial forearm muscles, grip one end of a dumbbell with both hands and perform radial deviations. To hit the ulnar muscles, hold the dumbbell closer to the thumb side and do ulnar deviations.

Radial and Ulnar deviation wrist training with my Rolling TopCurl.• #wriststrengthening #gripstrengthtraining #wristtraining #gripstrength @armassassinstrengthshop Rolling TopCurl

Stronger forearms = stronger EVERYTHING. Don’t skip the engines that power your grip Breakdown of the movements ⤵️ 📌 WRIST FLEXION (Flex the wrist / palm moves toward Forearm) 📌 WRIST EXTENSION (Extend the wrist / back of hand moves toward forearm) 📌 FOREARM PRONATION (Rotate palm down) 📌 FOREARM SUPINATION (Rotate palm up) 📌 FINGER FLEXOR TENDONS & PULLEYS 📌 ULNAR DEVIATION (Move wrist toward pinky) 📌 RADIAL DEVIATION (Move wrist toward thumb) Hope this helps! #fitness #exercise #strength #gripstrength #calisthenics #strengthtraining
