Abstracts - Continuous Passive Motion following total knee arthroplasty.

BACKGROUND: Knee arthroplasty (KA) is a common intervention that can enhance the quality of life for patients with osteoarthritis (OA) and rheumatoid arthritis (RA). Post-surgery rehabilitation protocols often include continuous passive motion (CPM). However, CPM protocols vary considerably amongst institutions. OBJECTIVES: The purpose of the current meta-analysis is to evaluate the effectiveness of continuous passive motion following total knee arthroplasty. SEARCH STRATEGY: An electronic search of MEDLINE (1966 to 2002), EMBASE (1988 to 2002), CINAHL (1982 to 2002), HEALTH STAR (1991 to 1994) and CURRENT CONTENTS (1997 to 2002) was conducted to identify randomized controlled trials.

OBJECTIVE: To assess the effects of lumbar spine stabilization using a pressure biofeedback unit on the electromyographic activity and angle of lateral pelvic tilt during hip abduction in a sidelying position. DESIGN: Comparative, repeated-measures study. SETTING: University research laboratory. PARTICIPANTS: Eighteen able-bodied volunteers (9 men, 9 women) with no history of pathology. INTERVENTION: Subjects were instructed to perform hip abduction in a sidelying position in both the preferred hip abduction (PHA) and hip abduction with lumbar stabilization (HALS). A pressure biofeedback unit was used for lumbar stabilization.

Applications of Surface Electromyography

Patellofemoral pain remains one of the most common disorders involving the knee and a common diagnosis encountered in outpatient orthopaedic practice.  Symptoms are typically described as a dull aching sensation in the retropatellar or peripatellar regions, however sharp, stabbing sensations also are common.  Pain is most often reproduced with activities that place high demands on the quadriceps muscle group such as squatting, ascending and descending stairs, and running.

Patellofemoral knee pain is one of the most common knee problems seen in a clinical setting (1, 2, 3). Caused by a variety of factors, patellofemoral pain is usually aggravated by activity that increases patellofemoral compressive forces (4).  Clinical assessment commonly finds abnormal patella tracking where the patella does not glide evenly in the trochlear groove, positive patella grind test and pain when palpating the patella’s medical and lateral boarders (5).

Classification

Shoulder dysfunction is a broad term used to group conditions with a great variety of etiologies. It can be acute in nature or can be the result of repetitive microtrauma. In actual fact, it appears that repetitive strain and microtrauma may be responsible for a greater number of shoulder problems than initially thought. In order to treat shoulder dysfunction effectively, it is necessary to have a good understanding of the pathology involved but, more importantly have a thorough understanding of the normal biomechanics of the shoulder girdle.
