Unlabelled: Strength data can help in guiding the return to sports (RTS) process in patients after an anterior cruciate ligament reconstruction (ACLR). There is need for a fast, cheap, and portable method to monitor muscle strength in patients after ACLR in an ambulatory stetting. Therefore, the purpose of the current study was to assess the use of a hand-held dynamometer (HHD) to monitor hamstring and quadriceps strength after ACLR and to assess the changes over time in patients tested at 3, 6 and 9 months after ACLR. It was hypothesized that patients show greater muscle strength at 6 months after ACLR compared to 3 months, and at 9 months after ACLR compared to 6 months. Forty-four amateur athletes (n = 44) after ACLR participated. Isometric hamstring and quadriceps strength were measured with a HHD at three time points during rehabilitation. Absolute isometric hamstring strength significantly progressed over time. Similar, absolute isometric quadriceps strength significantly progressed over time. This study showed that using handheld dynamometry can be a simple method to monitor the development of absolute isometric hamstring and quadriceps strength in patients after ACLR.

Background: Persistent maladaptive changes of corticospinal tract (CST) and quadriceps strength deficits exist in patients with anterior cruciate ligament reconstruction (ACLR). This study aimed to investigate the relationships between the structural alterations of CST and quadriceps muscle strength deficits in patients with ACLR.
Methods: Twenty-nine participants who had undergone unilateral ACLR (29 males; age = 32.

Background: People living with dementia (PWD) have upregulated inflammatory pathways, exaggerated metabolic aging, and cellular aging. They also have declines in physical function and heightened fall‐risk. Understanding the physiologic factors that influence physical decline and fall‐risk in PWD is vital to assess and prevent adverse health outcomes, such as future falls.

Introduction: Functional tests are used to establish the functional capacity of women with Greater Trochanteric Pain Syndrome (GTPS). However, the validity, reliability, or possibility of discriminating this dysfunction have not been established.
Objectives: To compare functional capacity, establish the properties of functional test measurements, and present the best test to discriminate between women with and without GTPS.

Introduction: Neuromuscular electrical stimulation (NMES) is a potentially effective intervention to improve outcomes after a fragility fracture, but its feasibility in this group has not been established.
Methods: A feasibility study was conducted in two phases: 1) in the hospital only, and 2) hospital, rehabilitation centres, and participants' homes. Patients with fragility fracture were randomised to receive NMES for 6 weeks/discharge either to the right or left leg, with the other leg serving as control.
