EZ Reacher

If you find yourself constantly reaching into high or low places, or if you have bad knees, the EZ reacher might just be the thing to prevent low back strain. I originally found this on Cool Tools, which gave it a favorable review for durability and ease of use. It might be the perfect thing to give an inflamed knee or back time to heal, especially after a surgery.

At Amazon for $17

Stand By Mi
One of the first recommendations I give to patients with neck/back pain is to raise their monitor to eye level and not to use a laptop as their primary computer. The most resistance I get is from, of course, Mac users because they don’t want to ruin the aesthetic of their setup. I just purchased a iMac and it was the most uncomfortable computer to work on until I raised it a few inches!
Hopefully the Stand by Mi can fill that functional void as it raises your monitor 3.3″. The platform looks like it will support an iMac and it has 4 USB 2.0 ports.
update:  the Stand By Mi no longer seems to be available, there is a similar product here.  It even raises the iMac a little higher.
Reebok Speed Pac

If you are looking for a great space saver for your home gym, you might consider these adjustable ‘click’ weights instead of purchasing a full set of dumbbells. Pictured is a pair of 12.5lb dumbbells which adjusts in 2.5lb increments. If you desire heavier weights the same thing is available as one Reebok Speed Pac 25-Pound Adjustable Single Dumbbell that adjusts at 5lb increments. There are several higher end brands(Powerblock & Stamina) which cost a lot more(>$150), but I found these at Target for $50.
Note: Adjustable ankle weights may be more appropriate for those with wrist/forearm injuries
