Grip Weakness What is grip weakness? Grip weakness is an ulnar nerve disorder that is typically caused by a trapped nerve in the elbow or wrist. What are the symptoms of grip weakness? Patients suffering from grip weakness typically report tingling, loss of sensation, elbow pain, aching in the funny bone, numbness in the fourth and fifth digits, and difficulty getting a firm grasp or grip on various objects. How do we treat grip weakness? When you come to our center, we start off by assessing the root cause of your condition, observing the way you hold your arms, grasp things, and twist your wrists, and search for any compensation patterns in other parts of your body. We then prescribe a series of strengthening exercises to build up the surrounding muscles in your hand, and stretch out the impacted area to increase flexibility and improve range of motion.
