Restless leg syndrome (RLS) is a common and sometimes
devastating condition. I see it quite frequently
in many of my chronic pain patients. In
fact, it contributes to quite a bit of chronic pain, because of the difficulty
it causes in terms of getting a good night's rest, and because it in and of
itself can be rather painful. And there
are diseases associated with chronic pain which can result in so-called
Restless Leg Syndrome is a nighttime condition that has a huge impact on
daytime functioning for those afflicted.
The diagnosis of RLS is mostly arrived at through interviews
with the patient, and basically involves four important features:
is a compelling need to move, usually associated with unpleasant
sensations in the legs, which have been described variously as painful,
electric or "creepy-crawly."
sensations of RLS are worse or exclusively present at rest.
sensations are at least partial...
Knee pain is a common problem among the young and old alike. From athletes to middle-aged adults to seniors, knee pain can develop suddenly. There are many potential causes owing to the fact that there can be ligament involvement, cartilage tears, muscle strains, cysts, arthritis, and more. Most of the time, knee pain is felt in the front of the knee or along either side. Posteromedial pain (inside back corner) is less common and more puzzling -- especially when it lasts a long time. The authors of this article bring to our attention the possible causes of posteromedial knee pain. In particular, the focus is on one that is infrequent but should be considered: semimembranosus tendinopathy . The semimembranosus muscle is part of what you might know otherwise as the hamstring muscle. It is made up of three separate but conjoined parts. This portion starts at the base of your sit bone (called the ischial tuberosity ). It travels down from the pelvis to the knee and inserts right along the po...
Studies show muscle weakness after total knee replacement (TKR) is common months and even years after the surgery. This study compares the force produced during a single-leg press after TKR. Nine patients with TKR were compared to nine adults without TKR (the control group). This is the first study to measure force produced by the leg after TKR in a weight-bearing position. It's unique because force is examined across several joints using many muscle groups. This gives a better idea of what's going on in a fully weight-bearing position. Other studies have reported on forces in one joint at a time. Often only the knee extensor muscles are tested. The authors report that there is much less force through the leg with the joint replacement. These measures were lower when compared to the patient's healthy leg and when compared to the control group. This shows that the entire leg, not just one set of muscles, has less power. The researchers suggest that the loss of force in the leg with the TK...
