Taping patients with clinical signs of subacromial impingement syndrome: the design of a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Shoulder problems are a common complaint of the musculoskeletal system. Physical therapists treat these patients with different modalities such as exercise, massage, and shoulder taping. Although different techniques have been described, the effectiveness of taping has not yet been established. The aim of this study is to assess the effectiveness and cost-effectiveness of usual physical therapy care in combination with a particular tape technique for subacromial impingement syndrome of the shoulder compared to usual physical therapy care without this tape technique in a primary healthcare setting.</p> <p>Methods and design</p> <p>An economic evaluation alongside a randomized controlled trial will be conducted. A sample of 140 patients between 18 and 65 years of age with a diagnosis of subacromial impingement syndrome (SAIS) as assessed by physical therapists will be recruited. Eligible patients will be randomized to either the intervention group (usual care in combination with the particular tape technique) or the control group (usual care without this tape technique). In both groups, usual care will consist of individualized physical therapy care. The primary outcomes will be shoulder-specific function (the Simple Shoulder Test) and pain severity (11-point numerical rating scale). The economic evaluation will be performed using a societal perspective. All relevant costs will be registered using cost diaries. Utilities (Quality Adjusted Life Years) will be measured using the EuroQol. The data will be collected at baseline, and 4, 12, and 26 weeks follow-up.</p> <p>Discussion</p> <p>This pragmatic study will provide information about the effectiveness and cost-effectiveness of taping in patients presenting with clinical signs of SAIS.</p> <p>Trial registration</p> <p>Trial registration number: <a href="http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=2575">NTR2575</a></p

Estimulação elétrica nervosa transcutânea nas modalidades convencional e acupuntura na dor induzida pelo frio

A estimulação elétrica nervosa transcutânea (TENS) é um recurso não-farmacológico já consagrado na modulação de dores agudas e crônicas. O objetivo deste estudo foi verificar o efeito da TENS convencional e na modalidade TENS-acupuntura na dor induzida pelo frio. Trinta indivíduos saudáveis com idade entre 18 e 40 anos foram distribuídos ao acaso em três grupos: placebo, TENS convencional e TENS-acupuntura. Foi utilizado um protocolo de indução de dor pelo frio composto por seis ciclos: dois pré-tratamento, dois durante e dois após o tratamento. A TENS foi aplicada por 20 minutos por dois canais, sendo a modalidade convencional, no nível sensorial, na freqüência de 80 Hz e a modalidade acupuntura, no nível motor, a 4 Hz. Foram medidos limiar de dor, tolerância à dor e intensidade da dor. Não foi encontrada diferença estatisticamente significante nos valores medidos durante a após o tratamento quando comparados aos dos ciclos pré-tratamento, em todas as variáveis. Nas duas modalidades estudadas pois, a TENS, nos parâmetros de aplicação utilizados, não modificou a dor induzida por frio, sugerindo-se novos estudos com maior tempo de aplicação da TENS e diferentes modelos de dor experimental.Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacological method already established in the modulation of acute and chronic pain. The purpose of this study was to assess the effect of conventional TENS and acupuncture-like TENS on cold-induced pain. Thirty healthy subjects aged 18 to 40 years old were randomized into in three groups: placebo, conventional TENS, and acupuncture-like TENS. A cold-induced pain protocol was used, in six cycles (two pre-treatment, two during, and two after treatment); TENS was applied for 20 minutes through 2 channels, the conventional modality at sensory level at 80 Hz, and the acupuncture modality at motor level at 4 Hz. Variables analysed were pain threshold, tolerance to pain, and pain intensity. No statistically significant differences were found in any variable between post and pre-treatment measures in all groups. Hence neither conventional or acupuncture-like TENS had any effect on cold-induced pain. Further studies are suggested, with different experimental pain models, and with longer time of TENS application

Physiotherapy Post Lumbar Discectomy: Prospective Feasibility and Pilot Randomised Controlled Trial

Objectives To evaluate: acceptability and feasibility of trial procedures; distribution of scores on the Roland Morris Disability Questionnaire (RMDQ, planned primary outcome); and efficient working of trial components. Design and Setting A feasibility and external pilot randomised controlled trial (ISRCTN33808269, assigned 10/12/2012) was conducted across 2 UK secondary care outpatient physiotherapy departments associated with regional spinal surgery centres. Participants Consecutive consenting patients aged >18 years; post primary, single level, lumbar discectomy. Interventions Participants were randomised to either 1:1 physiotherapy outpatient management including patient leaflet, or patient leaflet alone. Main Outcome Measures Blinded assessments were made at 4 weeks post surgery (baseline) and 12 weeks post baseline (proposed primary end point). Secondary outcomes included: Global Perceived Effect, back/leg pain, straight leg raise, return to work/function, quality of life, fear avoidance, range of movement, medication, re-operation. Results At discharge, 110 (44%) eligible patients gave consent to be contacted. 59 (54%) patients were recruited. Loss to follow up was 39% at 12 weeks, with one site contributing 83% losses. Mean (SD) RMDQ was 10.07 (5.58) leaflet and 10.52 (5.94) physiotherapy/leaflet at baseline; and 5.37 (4.91) leaflet and 5.53 (4.49) physiotherapy/leaflet at 12 weeks. 5.1% zero scores at 12 weeks illustrated no floor effect. Sensitivity to change was assessed at 12 weeks with mean (SD) change -4.53 (6.41), 95%CI -7.61 to -1.44 for leaflet; and -6.18 (5.59), 95%CI -9.01 to -3.30 for physiotherapy/leaflet. RMDQ mean difference (95%CI) between change from baseline to twelve weeks was 1.65(-2.46 to 5.75). Mean difference (95%CI) between groups at 12 weeks was -0.16 (-3.36 to 3.04). Participant adherence with treatment was good. No adverse events were reported. Conclusions Both interventions were acceptable, and it is promising that they both demonstrated a trend in reducing disability in this population. A randomised controlled trial, using a different trial design, is needed to ascertain the effectiveness of combining the interventions into a stepped care intervention and comparing to a no intervention arm. Findings will guide design changes for an adequately powered randomised controlled trial, using RMDQ as the primary outcome
