Do Other Rehabilitation Products, Exercise Devices And Medical Treatments For CTS And RSI's Work?

1. Gripping / Flexion Devices:
   
   
   • NO for CTS. Activities that require additional stress to the flexor muscles will cause them to become even stronger and more hypertonic (rigid), therefore increasing the muscle imbalance between the flexors and extensors. Sometimes these devices can offer short-term relief due to increased circulation, but long-term use often leads to more pain and discomfort due to increased damage to structures within the carpal tunnel.
2. Free-Weights:
   
   
   • NO for CTS. The strength imbalance between the flexor and extensor muscles will remain the same because both muscle groups are being exercised simultaneously. (Reverse wrist curls are directed at strengthening the extensor muscles, but you still have to contract the flexor muscles in order to grip/hold the weight.) The outcome is still a strength imbalance and the painful symptoms remain. Dual contraction of the flexor and extensor muscles can actually increase the compression of the carpal tunnel and the structures within. This compression decreases the space within the carpal tunnel, causing friction, inflammation and damage to the flexor tendons and median nerve as the wrist/hand is flexed and extended throughout the exercises.
   • YES for "Some" RSI's. Using free weights for some shoulder RSI's is ok as long as the exercises are performed in a nice controlled environment and proper form is utilized at all times. The FLEXTEND®-AC provides the perfect environment to get you strong enough to use heavier free weights for rehabilitation purposes as it offers smooth, consistent resistance throughout the entire range-of-motion (ROM) of all exercises.
3. Rubber Tubing and Resistive Exercise Bands:
   
   
   • NO for CTS. These bands only provide partial range of motion, only 1-3 joints used (depending on finger position), instead of 6 joints. Rubber bands do not allow the fingers to move throughout the full range of motion in either flexion or extension, abduction, or wrist and elbow extension. The combination of all of these motions being performed at once is critical for correcting carpal tunnel syndrome, because they stretch the strong, tight, overused flexor and adductor muscles of the hand, while strengthening the weaker, underused extensor and abductor muscles.
   • YES for Some RSI's: Using resistance bands for some RSI's is fine as long as a hand, wrist or elbow injury is not present, as all forms of resistance bands require the user to grip the tubing, band or handle which can cause additional strain to an existing injury, especially for those suffering with pain and/or a weak grip. For individuals suffering with an RSI that limits hand strength or causes pain in the upper extremity while gripping, will find the FLEXTEND-AC a tremendous relief as it requires no gripping at all. This allows RSI's, from fingertip to shoulder to be rehabilitated with ease without the risk of causing further discomfort or injury, resulting in a much quicker recovery rate.
4. Splints:
   
   
   1. Daytime:
      
      NO for CTS. Wrist braces and splints hold the wrist in the neutral position instead of the extensor muscles which should be doing it), in order to keep the wrist from moving into forced flexion and impinging the carpal tunnel even more. Using a brace to keep the wrist from dropping into flexion causes the already weak extensor muscles to become even weaker because you do not even have to utilize these muscles to keep the wrist from moving downward into flexion. Using these devices may provide some people with temporary relief for the first few weeks, but long-term use of splints and wrist braces increases the strength imbalance between the flexor and extensor muscles, possibly causing severe damage to the tendons, blood vessels and median nerve within the carpal tunnel.
   2. Nighttime:
      
      Yes for CTS. Using wrist braces and splints at night keeps people from making a "fist" with the wrist in a flexed forward position for 6-8 hours. Holding the wrist in the straight/neutral position is extremely important in order to prevent the flexor muscles from tightening down in a shortened position and impinging the structures within the carpal tunnel.
5. Wrist Splints and Anti-Inflammatories:
   
   NO for CTS. Failure rate is 81.6% (Including "partial success") in total alleviation of symptoms. Curative rate following treatment is 18.4%.Source: Kaplan, et al, 1990. J Hand Surgery.
6. Iontophoresis + Splinting:
   
   NO for CTS. Failure rate is 42.1% in total alleviation from symptoms. Source: Banta, et al, 1994. J Hand Surgery.
7. Steroid Injection:
   
   NO for CTS. Failure rate is 72.6% after 1-year follow up. ( Including "partial success" as failure) Source: Irwin, et al. J Hand Surgery.
8. Surgery:
   
   NO for CTS. When surgery is performed, the carpal ligament is severed in order to increase the space within the carpal tunnel, but since ligaments do not contract, it could not possibly cause the carpal tunnel to narrow. It is a combination of the finger adductor muscles and the wrist and finger flexor muscles that cause the carpal tunnel to narrow and impinge the median nerve. Patients who have had carpal tunnel surgery often times develop the same symptoms again because they develop scar tissue within the carpal tunnel due to improper rehabilitation, and the fact that the real disorder was never addressed. Also, patients will always have a weak grip strength because the carpal ligament has been removed, and it acts as a fulcrum point in which the flexor muscles push against for leverage in order to grasp an object or make a fist.
