Rehabilitation and return to sport after bilateral open surgery for femoroacetabular impingement in a professional ice hockey player: A case report
International audience; Background: The aim of this case report was to describe the rehabilitation and return to sport of a professional ice hockey player with symptomatic femoroacetabular impingement (FM) after bilateral open hip surgery.Case description: A 21-year-old professional ice hockey player with symptomatic FAT underwent bilateral surgical hip dislocations within a 6-week time period. After the second surgery (right hip), he experienced right hip pain due to iliotibial band dehiscence, which required additional revision surgery. The athlete underwent a standardized rehabilitation protocol. Hip muscle strength was objectively assessed during rehabilitation.Outcomes: Iliotibial band…
A multi-joint lower-limb tracking-trajectory test for the assessment of motor coordination.
This study aimed to determine whether a lower-limb trajectory-tracking task performed on a leg press machine, that is commonly adopted in both rehabilitation and resistance training settings, could yield reliable assessment of motor coordination in able-bodied individuals. Twenty-two female subjects allocated to two experimental groups were tested and retested after 48-72 h. Group A was fully familiarized with the experimental procedures before each test while group B received only verbal instructions. The unilateral coordination test consisted of target tracking during a simulated half squat including eccentric and concentric actions. In both groups, tracking error showed significant test-…
Differences in gait characteristics between total hip, knee, and ankle arthroplasty patients: a six-month postoperative comparison.
International audience; BACKGROUND: The recovery of gait ability is one of the primary goals for patients following total arthroplasty of lower-limb joints. The aim of this study was to objectively compare gait differences of patients after unilateral total hip arthroplasty (THA), total knee arthroplasty (TKA) and total ankle arthroplasty (TAA) with a group of healthy controls. METHODS: A total of 26 TAA, 26 TKA and 26 THA patients with a mean (+/- SD) age of 64 (+/- 9) years were evaluated six months after surgery and compared with 26 matched healthy controls. Subjects were asked to walk at self-selected normal and fast speeds on a validated pressure mat. The following spatiotemporal gait …
Reliability of knee extension and flexion measurements using the Con-Trex isokinetic dynamometer.
The aim of this study was to evaluate the reliability of isokinetic and isometric assessments of the knee extensor and the flexor muscle function using the Con-Trex isokinetic dynamometer. Thirty healthy subjects (15 males, 15 females) were tested and retested 7 days later for maximal strength (isokinetic peak torque, work, power and angle of peak torque as well as isometric maximal voluntary contraction torque and rate of torque development) and fatigue (per cent loss and linear slope of torque and work across a series of 20 contractions). For both the knee extensor and the flexor muscle groups, all strength data - except angle of peak torque - demonstrated moderate-to-high reliability, wi…
