Responses to: Weightlifting Devices For Bilateral Transradial Presentaion

Loren Schubert

Thank you to everyone who responded to my original post. For reference, here was my original question:
I am looking for a terminal device that would be appropriate for a patient with bilateral transradial presentation who is interested in weightlifting. He currently has body powered / cable operated devices with hooks that allow him to use exercise tubing and some cable type exercise machines. However, he is quite interested in using dumbbells or barbells for his workouts. Terminal devices such as the TRS Black Iron Max / Trainer would not be possible for use with a bilateral presentation. Does anyone have experience with a terminal device that could lock securely onto a barbell or dumbbell without the use of a sound side hand?
Here are the responses that I received:
1) I tried TAD WL device but it’s too narrow and barbell wobbles in it. That’s the beauty of TRS ones – they hold. If I were you, I’d have called Bob and find out if he could mod them for say harness operation or some sort of quick lock/unlock option. It’s almost your best bet, unless you have a local handyman that can “fix” 
2) Have you seen the “Carter Cuff”?
3) Use dumbbells instead instead of standard weight bars/sets? You can achieve the same results while fine tuning the left and right potential. It is also easier to get away from a weight that becomes uncontrollable.
4) I’m wondering if a myo quick disconnect wrist would work. I believe OB makes a connector which allows a 1/2”-20 screw to be interfaced with a myo wrist. The client would click in to go both sides. To disconnect, put each barbell down on the ground, walk around and twist the 180 deg. to release the first one, then do the second the same way. Best I can come up with on a Monday morning.
5) Sleeve the bar weld old end terminal s or even separate sockets welded end plates laminated correct rotation & distance along that line . The sleeve will allow the wt. to rotate as he lifts glad you have time to assist him.
Thank you again.
