Introduction A consequence of knee joint osteoarthritis (OA) is an inability to fully activate the quadriceps muscles, a problem termed arthrogenic muscle inhibition (AMI). AMI leads to marked quadriceps weakness that impairs physical function and may hasten disease progression. The purpose of the ...
tissue) such as Lyme disease and poliomyelitis, inherited myopathies such as certain muscular dystrophies and stroke, or neurological diseases such as multiple sclerosis or Bell’s palsy. An illness or injury that results in prolonged bed rest may cause disuse atrophy of the quadriceps muscles. ...
Quadriceps strength in men returned to the preoperative level, but not to normal strength. Quadriceps strength in women, at the final follow-up, was significantly less than it had been preoperatively. This weakness may be a consequence of impairment of the knee extensor mechanism resulting from ...
The surgical leg contracted differently, meaning that bundles of muscle fibers in the quadriceps were slower and lengthened less. Essentially, these fibers rotate less during a contraction, and when they rotate less, they ultimately position themselves in a way that results in less force production—...
Physical activity (PA) was assessed in 20 patients and all controls.Quadriceps muscle weakness was present in 56% of the patients. Peak oxygen uptake and 6-min walking distance were below normal in 89 and 75% of patients, respectively. Respiratory muscle strength was normal. The differences ...
Effects of electrical stimulation or voluntary contraction for strengthening the quadriceps femoris muscles in an aged male population. Since musculoskeletal impairment increases with age, it is important to determine if exercise changes age-related muscle weakness. This study compared the ... E Caggiano...
“diffuse, symmetric mild muscle edema involving the gluteal, adductor, quadriceps and hamstring muscles…suggestive of myopathy.” EMG and nerve conduction studies (NCS) showed a nonirritable myopathy involving the proximal muscles in the right vastus lateralis and right deltoid. A vastus lateralis ...
Muscles are essential components of our sensorimotor system that help maintain balance and perform a smooth gait, but it is unclear whether arthritic damag... MV Hurley,DL Scott,J Rees,... - 《Annals of the Rheumatic Diseases》 被引量: 1272发表: 1997年 Quadriceps Weakness and Osteoarthritis ...
This study investigates in vivo specific force of the quadriceps and ex vivo specific force of single muscle fibers in patients with IBM. We included 8 participants with IBM and 12 healthy controls, who all underwent quantitative muscle testing, quantitative MRI of the quadriceps and paired muscle...
L3, L4 Quadriceps L4 Tibialis anterior L5 Extensor hallicis longus S1, S2 Gastrocnemius, soleus The pattern of muscular weakness following injury to individual peripheral nerves reflects the range of muscles innervated by that particular nerve. The axonal loss of polyneuropathy produces weakness that is...
