A combined approach is recommended to treat chronic non-specific low back pain (lumbago), including pharmacological and non-pharmacological methods. Kinesiotherapy non-steroidal anti-inflammatory drugs (NSAIDs) have a high level of evidence in lumbago. includes posture daily motor activity regimen training, complex therapeutic breathing exercises, post-isometric relaxation, other physical exerc...

The purpose of this work was to determine if subjects initially trained to use a handgrip dynamometer could learn to perform the exercises at the same relative level of effort with a considerably less expensive substitute device. All subjects trained (4, 2-minute contractions, 30% maximal effort) 3 times per week for 12 weeks. In Study I, Group 1 (n = 13) trained using only the dynamometer whil...

[Purpose] The aim of present study was to investigate the effects of isometric quadriceps exercise on muscle strength, pain, and function in knee osteoarthritis. [Subjects and Methods] Outpatients (N=42, 21 per group; age range 40-65 years; 13 men and 29 women) with osteoarthritis of the knee participated in the study. The experimental group performed isometric exercises including isometric qua...

BACKGROUND Strength improvement of the shoulder muscles is a major goal in rehabilitation or athletic conditioning programs. The purpose of this study was to determine the effect of shoulder core exercises on the isometric torque of glenohumeral joint movements. METHODS A total of 36 healthy females with no history of shoulder injury enrolled in this study. Subjects were randomly assigned int...

CONTEXT Active physical training is commonly recommended for patients with chronic neck pain; however, its efficacy has not been demonstrated in randomized studies. OBJECTIVE To evaluate the efficacy of intensive isometric neck strength training and lighter endurance training of neck muscles on pain and disability in women with chronic, nonspecific neck pain. DESIGN Examiner-blinded randomi...

The reliability of electromyographic (EMG) data has been examined for isometric and slow dynamic tasks, but little is known about the repeatability of this data for ballistic movements. The purpose of this study was to examine the within-session, trial-to-trial reliability of a variety of quadriceps and hamstrings muscles during isometric and ballistic activities. Data were analyzed by way of i...

Introduction Gluteus Maximus (GMax) and Gluteus Medius (GMed) muscles are commonly weakened in hip osteoarthritis (OA), and functional weight-bearing (WB) exercises are frequently prescribed for gluteal strengthening. Muscle activity as an indicator of muscle recruitment can be measured using electromyography (EMG), with recruitment of >45% maximal voluntary isometric contraction (MVIC) require...
