Shoulder exercise

Kyle T Aune, Joseph M Powers
BACKGROUND: Extreme conditioning programs (ECPs) are fitness training regimens relying on aerobic, plyometric, and resistance training exercises, often with high levels of intensity for a short duration of time. These programs have grown rapidly in popularity in recent years, but science describing the safety profile of these programs is lacking. HYPOTHESIS: The rate of injury in the extreme conditioning program is greater than the injury rate of weightlifting and the majority of injuries occur to the shoulder and back...

The serratus anterior is portrayed as a homogeneous muscle in textbooks and during functional activities and rehabilitation exercises. It is unclear whether the serratus anterior is composed of subdivisions with distinctive morphology and functions. The purpose of this study was to determine whether the serratus anterior could be subdivided into different structural parts on the basis of its segmental architectural parameters. Eight formalin-embalmed serratus anterior muscles were dissected and the attachments of each fascicle documented...

BACKGROUND AND PURPOSE: The accurate performance of physical therapy exercises can be difficult. In this evolving healthcare climate it is important to continually look for better methods to educate patients. The use of handouts, in-person demonstration, and video instruction are all potential avenues used to teach proper exercise form. The purpose of this study was to examine if a corrected error video (CEV) would be as effective as a single visit with a physical therapist (PT) to teach healthy subjects how to properly perform four different shoulder rehabilitation exercises...

Transcranial direct current stimulation (tDCS) can increase cortical excitability of a targeted brain area, which may affect endurance exercise performance. However, optimal electrode placement for tDCS remains unclear. We tested the effect of two different tDCS electrode montages for improving exercise performance. Nine subjects underwent a control (CON), placebo (SHAM) and two different tDCS montage sessions in a randomised design. In one tDCS session, the anodal electrode was placed over the left motor cortex and the cathodal on contralateral forehead (HEAD), while for the other montage the anodal electrode was placed over the left motor cortex and cathodal electrode above the shoulder (SHOULDER)...

Polo, one of the world's oldest sports, is played in over 80 countries. It is unique in combining the skills of a person with the agility and performance of an animal in a contact sport. There is only one report of the frequency and type of injuries in this population. Here we report risk perception, mitigation and risk factors for injuries and falls in UK polo players. Data were collected retrospectively from a random sample of 112 UK polo players by telephone questionnaire. Injuries (commonly to a shoulder or wrist) requiring a hospital visit were sustained by 17...

: This randomized clinical trial investigated the effectiveness of exercise vs. exercise plus trigger point dry needling (TrP-DN) in subacromial pain syndrome. A randomized parallel-group trial, with 1-year follow-up was conducted. Fifty subjects with subacromial pain syndrome were randomly allocated to receive exercise alone or exercise +TrP-DN. Participants in both groups were asked to perform an exercise program of the rotator cuff muscles twice daily for 5 weeks. Further, patients allocated to the exercise +TrP-DN group also received dry needling to active TrPs in the muscles reproducing shoulder symptoms during the 2(nd) and 4(th) sessions...

OBJECTIVE: We have developed a low-cost, portable shoulder simulator designed to train basic arthroscopic skills. This study aimed to establish the construct validity of the simulator by determining which parameters discriminated between experience levels and to assess the experience of using the simulator. DESIGN: Participants were given an introductory presentation and an untimed practice run of a 6-step triangulation task using hooks and rubber bands. A total of 6 consecutive attempts at the task were timed, and the number of times the participant looked at their hands during the task was recorded...

BACKGROUND: The evidence for the effect of treatments of neck pain is modest. In the absence of causal treatments, a possibility is to tailor the treatment to the individuals' functional limitations and symptoms. The aim was to evaluate treatment effects of a tailored treatment versus a non-tailored treatment. Our hypothesis was that tailored treatment (TT) would have better effect on pain intensity and disability than either non-tailored treatment (NTT) (same treatment components but applied quasi-randomly) or treatment-as-usual (TAU) (no treatment from the study, no restrictions)...

Exercise is considered to be an effective supportive treatment approach in breast cancer (BC) patients. We conducted a randomized controlled trial to assess the efficacy of a 12-week PRT during radiotherapy. Strength performance was assessed by maximal isokinetic peak torque (MIPT) in two different angular velocities (60°/s and 180°/s) and maximal voluntary isometric contraction for shoulder external and internal rotation, as well as for knee extension and flexion were assessed pre- and post-intervention in 146 patients randomized to PRT or a control group...

OBJECTIVE: Shoulder internal (IR) and external rotator (ER) muscles play an important role in the stability of glenohumeral joint. The ratio between the peak torque of ER and IR in concentric (ER/IRPT) and mixed (ER-ECC/IR-CONPT) are usually measured to evaluate the effects of muscle weakness, sport activities, injury and treatment (Greenfield et al., 1990; Scoville et al., 1997). However, ER/IRPT and ER-ECC/IR-CONPT failed to provide some indication on the evolution of the ER/IR torque ratio (ER/IRTorque) and mixed torque ratio (ER-EC/IR-COTorque) during the range of motion (ROM)...

OBJECTIVE: Aquatic shoulder exercises are widely implemented into rehabilitation programs to provide early muscle strengthening and improved joint mobility. However, since the drag - the force exerted by the water on the moving segments - is very hard to measure, an in-depth knowledge of internal joint load is lacking, which ultimately prevents healthcare professionals from understanding all clinical implications. For the first time, shoulder joint moment, work, and power were calculated through a novel, validated numerical approach coupling fluid flow simulations and inverse dynamics...

OBJECTIVE: Winging of the scapula has a variety of causes and a variable prognosis. It contributes to a disruption of the scapulohumeral rhythm with a decreased flexion and abduction of the upper extremity and a source of a considerable pain. This condition can affect the ability to perform activities of daily living. The most common cause of scapula winging is serratus anterior paralysis resulting from a lesion of the long thoracic nerve. The rupture of the muscle itself remains uncommon...

OBJECTIVE: The chronic lateral epicondylitis is a common pathology with an economic impact. Actually, many costly therapies are prescribed without evidence of their effectiveness. Physical therapies seem to be neglected. However, they can correct actions at risk and involve the patient in his rehabilitation. MATERIAL/PATIENTS AND METHODS: This study evaluated the effectiveness of a standardized 2 month rehabilitation program composed of: an outpatient group education session, 18 liberal physical therapy sessions with correction of the posture of the trunk and shoulder, eccentric strengthening of the supinator muscles and the wrist extensor muscles, stretching, and some self daily exercises (transverse friction massage and stretching) according to Pernot-Comtet protocol...
