Prolotherapy, an injection-based complementary treatment for symptomatic knee osteoarthritis, was associated with improved knee-specific symptoms, quality of life, and ability to participate in daily activities among the majority of individuals who participated in several small clinical studies. This report documents the safety, comfort, and overall positive experiences with prolotherapy, as presented in an article in The Journal of Alternative and Complementary Medicine, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on The Journal of Alternative and Complementary Medicinewebsite until November 28, 2016.

Most participants described a substantial decrease in pain with injections of hypertonic dextrose in and around the affected knee joint, as reported in the article "Qualitative Assessment of Patients Receiving Prolotherapy for Knee Osteoarthritis in a Multimethod Study.

New research from the University of East Anglia (UEA) shows that, surprisingly, patients' physical activity does not increase following hip replacement surgery.

Total hip replacement is one of the most common elective operations, with more than 620,000 procedures performed in the UK from 2003-2013. The most prevalent cause for needing surgery is osteoarthritis (93 per cent).

But the research, published in the journal Clinical Rehabilitation, brings the purpose of a hip replacement into question.

This study is the first systematic review specifically to examine the differences in physical activity pre compared to post-surgery hip replacement.

Time to abandon this ineffective treatment, says linked editorial.

Receiving ultrasound after surgery to repair a fractured tibia (shinbone) does not accelerate healing or improve functional recovery compared with sham treatment, finds a trial of US patients published by The BMJ.

A linked editorial also published today, says there is now sound evidence that it doesn't work and suggests "it is time to abandon this ineffective treatment."

Tibial fractures are the most common long bone fracture. They heal slowly and often further surgery is needed to stimulate or accelerate the healing process.

Stroke and spinal cord injury patients often require gait rehabilitation to regain the ability to walk or to help strengthen their muscles. Wearable "robot-assisted training" is quickly emerging as a method that helps improve this rehab process.

In a major advance, researchers from Beihang University in China and Aalborg University in Denmark have designed a lower-limb robot exoskeleton - a wearable robot - that features natural knee movement to greatly improve patients' comfort and willingness to wear it for gait rehab.

As the team reports this week in Review of Scientific Instruments, from AIP Publishing, their robotic exoskeleton is intended to help stroke patients strengthen their physical fitness, aid the rehabilitation training of paralyzed patients, or to assist those who need help performing daily activities.

Stronger muscles reduce cognitive impairment in elderly patients.

The study was conducted in collaboration with the Centre for Healthy Brain Ageing (CHeBA) at the University of New South Wales and the University of Adelaide.

The results have been published in the Journal of American Geriatrics.

The trial involved a Study of Mental and Resistance Training (SMART) carried out on patients with mild cognitive impairment (MCI) between 55-68 years old.

A new evidence-based clinical guideline from the National Osteoporosis Foundation (NOF) and the American Society for Preventive Cardiology (ASPC) says that calcium with or without vitamin D intake from food or supplements that does not exceed the tolerable upper level of intake (2,000 to 2,500 mg/d) should be considered safe from a cardiovascular standpoint. Obtaining calcium from food sources is preferred, but supplements can be used to address dietary shortfalls. The guideline is published in Annals of Internal Medicine.

Calcium supplements have been recommended for persons who do not consume adequate calcium from their diet as a standard strategy for preventing osteoporosis-related fractures.
