Active clinical trials for "Shoulder Impingement Syndrome"

The aim of the study was to evaluate the effect of eccentric strength training for shoulder abductors on force steadiness in subjects with subacromial impingement syndrome (SIS).

Objective: A randomized clinical trial in order to evaluate the efficacy of structured eccentric exercises tutored by a physical therapist (PT) for patients with subacromial impingement. Hypothesis: H1 The exercises has a satisfactory effect and the need of an arthroscopic subacromial decompression can be reconsidered. H0 No difference between the two exercises (experimental and active control) and the patients still need surgery Further the study objective is to evaluate predictors for a positive or negative treatment response after three months of rehabilitation as well as after 12 months. Method: Patients referred to the orthopedic unit for an arthroscopic subacromial decompression, are offered a three month rehabilitation program during the waiting time for surgery which is approximately 4-6 months. All patients must have tried conservative treatments for at least 6 months in primary care with unsatisfactory results. The patients will be randomized to either the structured eccentric exercises tutored by a physical therapist or control exercises with general movements for the neck and shoulders. All patients has an equal number of sessions with the PT to offer similar attention. After three months the following key-question has to be answered: due to your current experience of your shoulder problems do you still need this surgical intervention? A blinded orthopedic surgeon evaluates the following outcomes at baseline and after three and twelve months. Primary outcomes: Constant-Murley shoulder assessment, Disabilities of the Arm Shoulder and Hans and different aspects of pain. Secondary outcomes; EQ-5D, sick-leave and return to work. All patients are evaluated with a diagnostic ultrasound in order to reveal the condition of the rotator cuff. Also long-term results in those who go thorough with the surgery and those who decline will be assessed after 12 months. Importance of the study results: Since there is no consensus about which intervention that should be preferred for patients with subacromial impingement the results of the current study is warranted. If this exercise program is successful it can be implemented into clinical practice. Further, clinical characteristics of patients that really need an arthroscopic subacromial decompression can be identified.

This study is a experimental one to observe the efficacy of joint mobilization and post facilitation techniques in shoulder impingement syndrome

Shoulder impingement syndrome is the most common shoulder disorder in overhead athletes. It describes a mechanical compression of subacromial bursa and rotator cuff tendons during arm movement, which results in pain and injuries. Most of previous studies focus on investigating motor performance in individuals with shoulder impingement syndrome and found altered scapular kinematics and muscle activation may contribute to the impingement. Recently few studies found changes in the central nervous system, decreases in corticospinal excitability and increases in inhibition in scapular muscles, by using transcranial magnetic stimulation (TMS). Although more studies are still needed to investigate the changes in central nervous system in the individuals with impingement syndrome, the changes in central nervous system are believed to be associated with the deficits of impingement syndrome. However, the exercise protocols for the impingement syndrome are usually designed to restore scapular kinematics and muscle activation, including scapular muscle strengthening exercise and scapular control exercise. To our knowledge, no study has investigated whether these exercise protocols can reverse these changes in the corticospinal system. The objectives of this proposal are to understand neuromuscular and neurophysiological mechanisms of the scapula-focused exercise protocols to improve the effectiveness of treatment. The study aims to investigate the effects of scapular muscle strengthening training and scapular control training on the scapular kinematics, muscle activation and corticospinal system. The study also aims to investigate whether any other cortical mechanisms are also affected by the shoulder impingement syndrome. We will recruit 70 overhead athletes with shoulder impingement syndrome and 22 healthy control athletes. Subjects with shoulder impingement syndrome will randomly receive either scapular muscle strengthening or scapular control training. When performing the exercise, subjects in the scapular control training group will receive electromyography feedback and cues but those in the strengthening training group will not. Immediate effects of these two training protocols on scapular kinematics, muscle activation, and neurophysiological measures will be tested before and after the training. Neurophysiological measures will be tested by TMS, including corticospinal excitability, cortical inhibition, intracortical inhibition, and intracortical facilitation.

This study compares the periodic effects of Accelerated rehabilitation protocol (ARP) and Mulligan mobilization with mowement method (MWM) in subacromial pain syndrome patients rehabilitation. Half of the participants will receive ARP, while the other half will receive MWM.

The aim of this study is to determine the effects of high intensity laser therapy (HILT) in patients with subacromial impingement syndrome (SIS). This study aims to compare the effects of HILT alone and HILT and therapeutic exercise combination on shoulder pain, ROM, joint position sense (JPS), muscle strength and function.The investigators hypothesized that shoulder pain, ROM, JPS, muscle strength and functionality would improve with both treatments but that HILT combined with exercise would result in better outcomes than HILT alone.

The aim of this study was to investigate the effects of scapular proprioceptive neuromuscular facilitation (PNF) techniques applied in addition to exercise therapy in patients with Subacromial impingement syndrome (SIS) on pain, pressure pain threshold (PPT), range of motion (ROM), functionality, scapular dyskinesis, active trigger points and emotional state.

This study evaluates the effects of corticosteroid injections over time, as well as the additional effect provided by subsequent transcranial direct current stimulation (tDCS) of the motor cortex on patients with rotator cuff tendinopathy of the shoulder. All patients will receive a subacromial corticosteroid injection. Two weeks later, a third will receive a treatment of tDCS, a third will receive a placebo a-tDCS treatment, and the last third will not receive any additional treatment.

Background: Rounded shoulder posture (RSP), associated with altered scapular kinematics and imbalance of muscle activation, is one of potential risks for shoulder impingement syndrome (SIS) due to alignment deviation of scapula. Evidence showed shoulder brace improved degree of RSP by postural correction. However, it is unknown whether shoulder brace with different characteristics (tension and direction) is optimal for muscle activation and scapular kinematics in patients with SIS and RSP. Objective: There are 4 objectives for the present study: (1) to investigate the relationships among degree of RSP, scapular kinematics and muscle activation in SIS patients with RSP; (2) to compare the effect of shoulder brace on degree of RSP, muscle balance ratios (Upper trapezius/Lower trapezius, Upper trapezius/ Serratus anterior) and scapular kinematics (upward/downward rotation, anterior/posterior tilt, external/internal rotation) during arm movements; (3) to compare the effect of two tensions of brace strap (self-comfortable and forced tension) in symptomatic impingement patients with RSP; (4) to compare the effect of two types of direction of strap (paraspinal muscle and diagonal orientation) in symptomatic impingement patients with RSP. Design: Patients with SIS and RSP will be recruited in this study. Participants will be randomly assigned into 2 groups (self-comfortable following forced tension and forced following self-comfortable tension groups) with 2 directions of strap in each tension wearing shoulder brace. Each patient has the assessment 2 times with 1-week interval. Pectoralis minor, acromial distance, scapular index and shoulder angle will be used to assess degree of RSP. Three-dimensional electromagnetic motion analysis and electromyography muscle activity will be used to record the scapular kinematic, absolute muscle activation and muscular balance ratios during arm movements with or without shoulder brace. Main outcome measures: Scapula kinematic (upward/downward rotation, anterior/posterior tilt, external/internal rotation), absolute muscle activation (Upper trapezius, Middle Trapezius, Lower trapezius, Serratus anterior) and muscle balance ratios (Upper trapezius/Lower trapezius, Upper trapezius/Serratus anterior) are main outcomes of the study.

Various stretches are used to lengthen the posterior shoulder capsule. No study has reported the comparison of the pragmatic posterior capsular stretch and cross body stertch
