Muscle atrophy from steroid injection

Hip pain that may cause a limp during walking. Lying on the affected side may be too painful and result in disturbed sleep. Pain on rising from sitting and standing up straight. The pain in the hip area can be severe and constant with no let up either lying down or walking. As this muscle lies close to the Piriformis, the pain patterns are similar. Like the Piriformis it can cause SI joint dysfunction. But whereas the Piriformis pain pattern can extend down to the knee, the minimus pattern includes the calf and the thigh. Low back pain in the sacral and sacroiliac regions is most likely be due to problems in the gluteus medius. Pain referred from trigger points in the gluteus medius is less likely to involve the thigh; gluteus maximus trigger points restricts flexion at the hip whilst Piriformis trigger points restricts medial rotation.

One of the most commonly asked questions here at Stimrx is “What is the difference between TENS and EMS?” Most people assume that TENS and EMS are similar enough to be interchangeable. StimRx wants to make sure you know the differences in the two, and the importance of when to use each of the modes with our equipment. Both TENS and EMS devices use a power supply, lead wires and identical electrodes to supply the electrical impulses to the body. However, their purpose is quite different. Most machines offer both TENS and EMS programs to choose from. You can select not... read more

Bed rest, a ground-based spaceflight analog, induces robust atrophy of skeletal muscle, an effect that is exacerbated with increasing age. We examined the effect of 14 days of bed rest on skeletal muscle satellite cell content and fiber type atrophy in middle-aged adults, an understudied age demographic with few overt signs of muscle aging that is representative of astronauts who perform long-duration spaceflight. Muscle biopsies were obtained from the vastus lateralis of healthy middle-aged adults [n= 7 (4 male, 3 female); age: 51 ± 1 yr] before (Pre-BR) and after (Post-BR) 14 days of bed rest. Immunohistochemical analyses were used to quantify myosin heavy chain (MyHC) isoform expression, cross-sectional area (CSA), satellite cell and myonuclear content, and capillary density. Peak oxygen consumption, knee extensor strength, and body composition were also measured Pre-BR and Post-BR. Post-BR MyHC type 2a fiber percentage was reduced, and mean CSA decreased in all fiber types (-24 ± 5%;P< ). Satellite cell content was also reduced Post-BR (-39 ± 9%;P< ), and the change in satellite cell content was significantly correlated with the change in mean fiber CSA (r(2)= ;P< ). A decline in capillary density was observed Post-BR (-23 ± 6%;P< ), and Post-BR capillary content was significantly associated with Post-BR peak aerobic capacity (r(2)= ;P< ). A subtle decline in myonuclear content occurred during bed rest (-5 ± 1%;P< ). The rapid maladaptation of skeletal muscle to 14 days of mechanical unloading in middle-aged adults emphasizes the need for robust countermeasures to preserve muscle function in astronauts.
