Among anterior cruciate ligament reconstructions on 111 sports-focused individuals age 18 years to 50 years, 31% demonstrated evidence of osteoarthritis (OA) 1 year after reconstructive surgery. Location of the OA most frequently was the patellofemoral compartments.

Three Austrian men with hand function severely limited by brachial plexus injuries chose to have portions of their upper extremities amputated as part of a "bionic reconstruction," allowing them to wear a thought-controlled prosthetic hand.

Sensory, emotional, and cognitive cues, rather than objective, physiological sources, may be among the factors that significantly influence how pain is experienced.

A new study in Journal of Bone & Joint Surgery determined there is significant benefit for patients older than 80 years who undergo surgical treatment for lumbar spinal stenosis with and without degenerative spondylolisthesis. The study also finds no higher overall complication rate, nor higher mortality for patients age 80 years and older compared to younger patients.

A wide range of users may be getting inaccurate data from wearable activity trackers about the calories they expend. Research efforts based at the University of Wisconsin, LaCrosse, show that some wearables generate calorie burn data that varies from 13% to 60% of the true values.

Arguments have been made for several years defending and refuting the effectiveness of chondroitin sulfate as treatment for osteoarthritis (OA). A recent review carried out by The Chochrane Collaboration, however, concludes that the drug does provide significant pain relief for OA.

A Denmark-based study concludes that individuals who follow strenuous jogging programs are as likely to die as sedentary individuals who do not jog. The study, published in the Journal of the American College of Cardiology, tracked factors such as hours jogged, frequency, and pace.

The cerebellum may deserve more credit for its role in higher brain functions, and appears it could be effective as a target for brain-controlled interfaces for assistive technologies such as robotic arms.

Science seems to have found a way to objectively measure the presence and intensity level of pain. Investigators at Massachusetts General Hospital (MGH) have uncovered evidence that points to rising levels of pain-associated proteins in the brain that are linked to areas of the organ that transmit pain signals.

Medicine balls found commonly in the therapy clinic may be extremely useful as a fall prevention tool among older adults, according to research at University of Illinois at Chicago. A study there determined a simple routine of throwing and catching a weighted medicine ball can improve balance and potentially help prevent falls among older adults.

Researchers based at Brunel University London recently concluded a study that found individuals affected by multiple sclerosis (MS) who have a mobility deficit should be holistically assessed when offered a power wheelchair.

A chicken without a head running through a barnyard exemplifies how the spinal cord transmits motor signals after connection to the brain has been lost. Along similar lines, researchers in Italy recently identified the mechanisms the human spinal cord uses to control muscle activity even if neural pathways from the brain are physically interrupted.
Cole Eichelberger, age 13 years, participates in the testing of a new video game that potentially will open the door for wheelchair-bound children to participate in clinical trials for which they otherwise would be required to walk.
Duchenne muscular dystrophy can confine children to a wheelchair, thereby excluding them from participating in clinical trials. A video game recently used to successfully measure upper extremity movement of non-ambulatory children affected by the condition potentially opens the door for their participation in future trials.
