    Input: Background and purpose A programme based on eccentric exercises for treating subacromial pain was in a previous study found effective at 3-month follow-up . The purpose s of the present study were to investigate whether the results were maintained after 1 year and whether the baseline Constant-Murley score , rotator cuff status and radiological findings influenced the outcome . Patients and methods 97 patients on the waiting list for arthroscopic subacromial decompression had been r and omised to a specific exercise programme or unspecific exercises ( controls ) .  After 3 months of exercises , the patients were asked whether they still wanted surgery and this option was available until a 1-year follow-up . 1 year after inclusion or 1 year after surgery , the number of patients who decided to have surgery in each group was compared . The choice of surgery was related to the baseline Constant-Murley score , ultrasound and radiographs taken at inclusion . Results All patients had improved significantly ( p<0.0001 ) in the Constant-Murley score at the 1-year follow-up . Significantly more patients in the control group decided to have surgery ( 63 % ) than those in the specific exercise group ( 24 % ; p<0.0001 ) . Patients who decided to have surgery had a significantly lower baseline Constant-Murley score and more often a full-thickness tear . Patients with partial tears did not differ from those with intact tendons . Interpretation The positive short-term results of specific exercises were maintained after 1 year , and this exercise strategy reduces the need for surgery . Full-thickness tear and a low baseline Constant-Murley score appear to be a predictive marker for a less good outcome . Trial registration number Clinical trials NCT01037673 STUDY DESIGN A prospect i ve r and omized clinical trial . OBJECTIVE To compare the effectiveness of 2 physical therapy treatment approaches for impingement syndrome of the shoulder . BACKGROUND Manual physical therapy combined with exercise is a commonly applied but currently unproven clinical treatment for impingement syndrome of the shoulder . METHODS AND MEASURES Thirty men and 22 women ( age 43 years + /- 9.1 ) diagnosed with shoulder impingement syndrome were r and omly assigned to 1 of 2 treatment groups . The exercise group performed supervised flexibility and strengthening exercises . The manual therapy group performed the same program and received manual physical therapy treatment . Both groups received the selected intervention 6 times over a 3-week period . The testers , who were blinded to group assignment , measured strength , pain , and function before treatment and after 6 physical therapy visits . Strength was a composite score of isometric strength tests for internal rotation , external rotation , and abduction . Pain was a composite score of visual analog scale measures during resisted break tests , active abduction , and functional activities . Function was measured with a functional assessment question naire . The visual analog scale used to measure pain with functional activities and the functional assessment question naire were also measured 2 months after the initiation of treatment . RESULTS Subjects in both groups experienced significant decreases in pain and increases in function , but there was significantly more improvement in the manual therapy group compared to the exercise group . For example , pain in the manual therapy group was reduced from a pretreatment mean ( + /- SD ) of 575.8 ( + /- 220.0 ) to a posttreatment mean of 174.4 ( + /- 183.1 ) . In contrast , pain in the exercise group was reduced from a pretreatment mean of 557.1 ( + /- 237.2 ) to a posttreatment mean of 360.6 ( + /- 272.3 ) . Strength in the manual therapy group improved significantly while strength in the exercise group did not . CONCLUSION Manual physical therapy applied by experienced physical therapists combined with supervised exercise in a brief clinical trial is better than exercise alone for increasing strength , decreasing pain , and improving function in patients with shoulder impingement syndrome Evidence -based practice involves the use of evidence from systematic review s and r and omised controlled trials , but the extent of this evidence in physiotherapy has not previously been surveyed . The aim of this survey is to describe the quantity and quality of r and omised controlled trials and the quantity of systematic review s relevant to physiotherapy . The Physiotherapy Evidence Data base ( PEDro ) was search ed . The quality of trials was assessed with the PEDro scale . The search identified a total of 2,376 r and omised controlled trials and 332 systematic review s. The first trial was published in 1955 and the first review was published in 1982 . Since that time , the number of trials and review s has grown exponentially . The mean PEDro quality score has increased from 2.8 in trials published between 1955 and 1959 to 5.0 for trials published between 1995 and 1999 . There is a substantial body of evidence about the effects of physiotherapy . However , there remains scope for improvements in the quality of the conduct and reporting of clinical trials OBJECTIVES : Conflicting results were reported about the effectiveness of Low level laser therapy on musculoskeletal disorders . The aim of this study was to investigate the effectiveness of 850‐nm gallium arsenide aluminum ( Ga‐As‐Al ) laser therapy on pain , range of motion and disability in subacromial impingement syndrome . METHODS : A total of 52 patients ( 33 females and 19 males with a mean age of 53.59±11.34 years ) with subacromial impingement syndrome were included . The patients were r and omly assigned into two groups . Group I ( n = 30 , laser group ) received laser therapy ( 5 joule/cm2 at each point over maximum 5‐6 painful points for 1 minute ) . Group II ( n = 22 , placebo laser group ) received placebo laser therapy . Initially cold pack ( 10 minutes ) was applied to all of the patients . Also patients were given an exercise program including range of motion , stretching and progressive resistive exercises . The therapy program was applied 5 times a week for 14 sessions . Pain severity was assessed by using visual analogue scale . Range of motion was measured by goniometer . Disability was evaluated by using Shoulder Pain and Disability Index . RESULTS : In group I , statistically significant improvements in pain severity , range of motion except internal and external rotation and SPADI scores were observed compared to baseline scores after the therapy ( p<0.05 ) . In Group II , all parameters except range of motion of external rotation were improved ( p<0.05 ) . However , no significant differences were recorded between the groups ( p>0.05 ) . CONCLUSIONS : The Low level laser therapy seems to have no superiority over placebo laser therapy in reducing pain severity , range of motion and functional disability Background : Repetitive or sustained elevated shoulder postures have been identified as a significant risk factor for occupationally related shoulder musculoskeletal disorders . Construction workers exposed to routine overhead work have high rates of shoulder pain that frequently progresses to functional loss and disability . Exercise interventions have potential for slowing this progression . Aims : To evaluate a therapeutic exercise programme intended to reduce pain and improve shoulder function . Methods : Construction worker volunteers were screened by history and clinical examination to test for inclusion /exclusion criteria consistent with shoulder pain and impingement syndrome . Sixty seven male symptomatic workers ( mean age 49 ) were r and omised into a treatment intervention group ( n = 34 ) and a control group ( n = 33 ) ; asymptomatic subjects ( n = 25 ) participated as an additional control group . Subjects in the intervention group were instructed in a st and ardised eight week home exercise programme of five shoulder stretching and strengthening exercises . Subjects in the control groups received no intervention . Subjects returned after 8–12 weeks for follow up testing . Results : The intervention group showed significantly greater improvements in the Shoulder Rating Question naire ( SRQ ) score and shoulder satisfaction score than the control groups . Average post-test SRQ scores for the exercise group remained below levels for asymptomatic workers . Intervention subjects also reported significantly greater reductions in pain and disability than controls . Conclusions : Results suggest a home exercise programme can be effective in reducing symptoms and improving function in construction workers with shoulder pain Objective To investigate the efficacy of a programme of manual therapy and exercise treatment compared with placebo treatment delivered by physiotherapists for people with chronic rotator cuff disease . Design R and omised , participant and single assessor blinded , placebo controlled trial . Setting Metropolitan region of Melbourne , Victoria , Australia . Participants 120 participants with chronic ( > 3 months ) rotator cuff disease recruited through medical practitioners and from the community . Interventions The active treatment comprised a manual therapy and home exercise programme ; the placebo treatment comprised inactive ultrasound therapy and application of an inert gel . Participants in both groups received 10 sessions of individual st and ardised treatment over 10 weeks . For the following 12 weeks , the active group continued the home exercise programme and the placebo group received no treatment . Main outcome measures The primary outcomes were pain and function measured by the shoulder pain and disability index , average pain on movement measured on an 11 point numerical rating scale , and participants ’ perceived global rating of overall change . Results 112 ( 93 % ) participants completed the 22 week trial . At 11 weeks no difference was found between groups for change in shoulder pain and disability index ( 3.6 , 95 % confidence interval −2.1 to 9.4 ) or change in pain ( 0.7 , −0.1 to 1.5 ) ; both groups showed significant improvements . More participants in the active group reported a successful outcome ( defined as “ much better ” ) , although the difference was not statistically significant : 42 % ( 24/57 ) of active participants and 30 % ( 18/61 ) of placebo participants ( relative risk 1.43 , 0.87 to 2.34 ) . The active group showed a significantly greater improvement in shoulder pain and disability index than did the placebo group at 22 weeks ( between group difference 7.1 , 0.3 to 13.9 ) , although no significant difference existed between groups for change in pain ( 0.9 , −0.03 to 1.7 ) or for the percentage of participants reporting a successful treatment outcome ( relative risk 1.39 , 0.94 to 2.03 ) . Several secondary outcomes favoured the active group , including shoulder pain and disability index function score , muscle strength , interference with activity , and quality of life . Conclusion A st and ardised programme of manual therapy and home exercise did not confer additional immediate benefits for pain and function compared with a realistic placebo treatment that controlled for therapists ’ contact in middle aged to older adults with chronic rotator cuff disease . However , greater improvements were apparent at follow-up , particularly in shoulder function and strength , suggesting that benefits with active treatment take longer to manifest . Trial registration Clinical trials NCT00415441 OBJECTIVE The aim of this study was to determine the effectiveness of Kinesio taping ( KT ) application added to the exercise treatment of subacromial impingement syndrome ( SIS ) . METHODS Thirty-eight ( 25 female , 13 male ) patients with SIS were r and omly divided into therapeutic KT ( n=19 ) and sham KT ( n=19 ) groups . All patients received the same exercise therapy in addition to therapeutic or sham KT at 3-day intervals for 12 days . The groups were compared according to pain , range of motion ( ROM ) , muscle strength and DASH and Constant scores before treatment and at the 5th and 12th treatment days . RESULTS Within group comparisons showed significant improvements in both groups at the 5th and 12th day evaluations ( p<0.05 ) . In comparisons between the groups , pain with movement and DASH scores in the therapeutic group were significantly lower at the 5th day ( p<0.01 ) . There were significant improvements in night pain , pain with movement , DASH score , shoulder external rotation muscle strength , and pain free shoulder abduction ROM in the therapeutic group at the 12th day ( p<0.05 ) . Passive shoulder flexion ROM increased more in the sham group at the 12th day ( p<0.05 ) . CONCLUSION The addition of KT application to the exercise program appears to be more effective than the exercise program alone for the treatment of SIS Background The physiotherapy dynamic humeral centring ( DHC ) aims to prevent subacromial impingement of rotator cuff tendons during elevation of the arm . The objective of the study was to determine whether DHC acts via an effect on subacromial impingement mechanism by assessing its effect on painful elevation of the arm in subacromial impingement syndrome . Methods This is a secondary analysis of results of a r and omised controlled trial of the effectiveness of DHC .  Sixty-nine patients with subacromial impingement syndrome were prospect ively included . Patients and the assessor were blinded to the study hypothesis and treatment , respectively . Patients underwent DHC or non-specific mobilisation as a control for 6 weeks in 15 supervised individual outpatient sessions with home exercises . Outcomes were pain-free range of motion and presence of painful arc of the shoulder , both in active flexion and abduction of the arm at 3 months . Results At 3 months , pain-free range of motion , both flexion and abduction , was greater in the DHC group than in the mobilisation group . The number of patients with painful arc during flexion was decreased in the DHC group . Conclusions DHC improves painful active elevation of the arm . We suggest that DHC may act via a specific effect on subacromial impingement mechanism BACKGROUND AND PURPOSE Exercise therapy is a commonly used conservative therapy for long-term subacromial pain . However , there is no consensus regarding what type of exercises and dosage is most effective . The aim of this study was to compare the effect of two exercise programmes : 1 ) high-dosage ( HD ) medical exercise therapy versus 2 ) low-dosage ( LD ) exercise therapy 
    Output:
    
Exercise therapy provided high evidence of being as effective as surgery intervention and better than no treatment or placebo treatment to improve pain , function and range of motion in the short , mid and long terms .
The combination of mobilisation and exercises provided high evidence to decrease pain and improve function in the short term .
There is limited evidence for improvements on the outcomes with the isolated application of manual therapy .
High level of evidence was synthesis ed regarding the lack of beneficial effects of physical re sources such as low-level laser , ultrasound and pulsed electromagnetic field ( PEMF ) on pain , function or range of motion in the treatment of SAPS .
There is limited evidence for microwave diathermy and transcutaneous electrical nerve stimulation .
There is moderate evidence to no benefits with taping in the short term .
Effects of diacutaneous fibrolysis and acupuncture are not well established yet .
Exercise therapy should be the first-line treatment to improve pain , function and range of motion .
The addition of mobilisations to exercises may accelerate reduction of pain in the short term .
