If you have night-time leg cramps or spasms 3 or more times per week, you may be eligible to participate in a research study being conducted at Sport and Spine Rehab (SSR).
You will be compensated up to $150 for involvement in this study.
This study is examining the effect of a foam that you apply to your legs in the evenings when you are experiencing night-time cramps or spasms.
Nocturnal or night-time cramps and spasms are involuntary and painful contractions of muscles usually involving the thigh, calf or foot muscles. A definition of nocturnal or night-time cramps and spasms has been proposed by American Academy of Sleep Medicine International Classification of Sleep Disorders to include the following criteria:
- A painful sensation in the leg or foot associated with sudden, involuntary muscle hardness or tightness, indicating a strong muscle contraction.
- The painful muscle contractions occur during the time in bed, although they may arise from either wakefulness or sleep.
- The pain is relieved by forceful stretching of the affected muscles, thus releasing the contraction.
- Visit SSR 3 times, for an hour each time, over 4 weeks
- Complete questionnaires about your health during each of these visits
- Keep a log of your night-time cramps for 4 weeks
During the first two weeks you will receive no treatment. During the second 2 weeks you will receive a dispenser from which to apply foam to your legs in the evenings.
