Causes of Difficulty Moving
Moving may be difficult because of disorders that restrict joint motion or that cause weakness, Joint Stiffness , A joint may have limited range of motion because of Pain Previous joint injury causing significant scar tissue Prolonged joint immobilization (for example, when a person's arm is paralyzed by a stroke or placed in a sling) causing shortening of the tendons Fluid accumulation in a joint resulting from arthritis or an acute injury (giving a sensation that the joint is locked) A piece of torn cartilage (resulting from an injury, typically in the knee) that blocks joint movement Although many people complain of weakness when they feel tired or run down, true Weakness means that full effort does not generate normal, strong muscle contractions. Normal voluntary muscle contraction requires the brain to generate a signal that then travels through the spinal cord and nerves to reach a normally functioning muscle. Therefore, true weakness can result from injury or disease affecting the nervous system, muscles, or connections between them (neuromuscular junction).
