Non-Invasive Radiofrequency Diathermy Neuromodulation Added to Supervised Therapeutic Exercise in Patellofemoral Pain Syndrome: A Single Blind Randomized Controlled Trial with Six Months of Follow-Up.

The evidence-based treatment of patellofemoral pain (PFP) suggests that therapeutic exercise (TE) focused on improving muscle strength and motor control be the main conservative treatment. Recent research determined that the success of the TE approach gets improved in the short term by the addition of neuromodulation via radiofrequency diathermy (RFD). As there is no follow up data, the objective of this research is to assess the long-term effects of adding RFD to TE for the pain, function and quality of life of PFP patients. To this aim, a single-blind randomized controlled trial was conducted on 86 participants diagnosed of PFP. Participants who met the selection criteria were randomized and allocated into either a TE group or an RFD + TE group. TE consisted of a 20 min daily supervised exercise protocol for knee and hip muscle strengthening, while RFD consisted of the application of neuromodulation using a radiofrequency on the knee across 10 sessions. Sociodemographic data, knee pain and lower limb function outcomes were collected. The RFD + TE group obtained greater improvements in knee pain (p < 0.001) than the TE group. Knee function showed statistically significant improvements in Kujala (p < 0.05) and LEFS (p < 0.001) in the RFD + TE group in the short and long term. In conclusion, the addition of RFD to TE increases the beneficial effects of TE alone on PFP, effects that remain six months after treatment.

Effects of Radiofrequency Diathermy Plus Therapeutic Exercises on Pain and Functionality of Patients with Patellofemoral Pain Syndrome: A Randomized Controlled Trial.

Although consensus has been reached about the use of therapeutic exercise in patellofemoral pain syndrome, several techniques used worldwide such as radiofrequency diathermy could be useful as complementary therapy. The objective of this randomized controlled trial was to compare the effects of adding radiofrequency diathermy to therapeutic exercises in patients with patellofemoral pain syndrome. Fifty-six participants were randomly assigned either to radiofrequency diathermy plus therapeutic exercises group (n = 29) or therapeutic exercises group (n = 27). Both groups received the same therapeutic exercises, and the diathermy group additionally received monopolar dielectric diathermy for three weeks (5-3-2 weekly sessions). Data related to intensity of pain, probability of neuropathic pain, functionality, and range of movement of the knee were measured at baseline and three weeks after the intervention. Comparing pre-treatment and values obtained at the third week, significant improvements were found in intensity of pain, neuropathic pain, functionality, and range of motion in both groups (p < 0.05). The diathermy plus exercises group had significantly better intensity of pain than the control group at the end of the three weeks (p < 0.01). The addition of diathermy by emission of radiofrequency to the therapeutic knee exercise protocol is more effective than a therapeutic exercise protocol alone in the relief of intensity of pain in patients with patellofemoral pain in the immediate post-treatment follow-up compared with baseline scores.

Treatment of Patellofemoral Pain Syndrome with Dielectric Radiofrequency Diathermy: A Preliminary Single-Group Study with Six-Month Follow-Up.

Background and Objectives: Notwithstanding patellofemoral pain syndrome (PFPS) being one of the most common causes of pain in the front of the knee in outpatients, few studies have shown the effects of radiofrequency on knee pain and function in this population. The aim of the present study was to determine whether outpatients diagnosed with PFPS obtained improvement in pain and function after treatment by dynamic application of monopolar dielectric diathermy by emission of radiofrequency (MDR). Materials and Methods: An experimental study was conducted with 27 subjects with PFPS. Subjects were treated with 10 sessions of MDR in dynamic application. The visual analogue scale (VAS), the Kujala scale, the DN4 questionnaire, the lower extremity function scale (LEFS), the range of movement (ROM) in knee flexion and extension and the daily drug intake were measured pre- and post-intervention and at the time of the follow-up (six months). Results: Statistically significant differences were found in pain perception (VAS: F1,26 = 92.43, p < 0.000, ŋ2 = 0.78 and DN4: F1.26 = 124.15, p < 0.000, ŋ2 = 0.82), as well as improvements in functionality (LEFS: F1.26 = 72.42, p < 0.000, ŋ2 = 0.74 and Kujala: F1.26 = 40.37, p < 0.000, ŋ2 = 0.61]) and in ROM (Flexion: F1.26 = 63.15, p < 0.000, ŋ2 = 0.71). No statistically significant changes in drug intake were found. Conclusions: The present study shows that the dynamic application of MDR seems effective in reducing pain and increasing functionality and knee flexion in patients with PFPS, after a follow-up of six months.

Construction, Factor Structure, and Internal Consistency Reliability of the Hospital Physical Therapy Perceived Satisfaction Questionnaire (H-PTPS).

Patient satisfaction is a crucial aspect in the evaluation of the quality of health care provided by health services and units, especially in patients that require physical rehabilitation. This study aims to design and analyze the factor structure and internal consistency reliability of the Hospital Physical Therapy Perceived Satisfaction Questionnaire (H-PTPS) measuring the level of physical therapy patient satisfaction in hospital rehabilitation services. This study has a multicenter cross-sectional survey design. This study used the structural validity and internal consistency domains from COSMIN (consensus-based standards for the selection of health status measurement instruments) guideline. The H-PTPS questionnaire consists of 20 closed questions. A sample of 384 adult patients from physical therapy units from three Spanish public hospitals completed this questionnaire. A factor structure and internal consistency reliability analysis were performed. The factor analysis including the 20 items of the H-PTPS showed an adequacy index of 0.922 according to the Kaiser-Meyer-Olkin measure and the Barlett test allowed us to reject the null hypothesis (p < 0.001). In the rotated component matrix, four specific factors were obtained, explaining 66.75% of the accumulated variance. All factors present satisfactory internal reliability, achieving Cronbach's alpha indices and Omega coefficients higher than 0.74. The H-PTPS questionnaire has shown a four-factor solution with satisfactory reliability evaluating the satisfaction of Spanish patients treated in physical therapy units in the hospital rehabilitation services.

Effect of adding interferential current stimulation to exercise on outcomes in primary care patients with chronic neck pain: a randomized controlled trial.

OBJECTIVE: To evaluate the effect of adding interferential current stimulation to exercise on pain, disability, psychological status and range of motion in patients with neck pain. DESIGN: A single-blinded randomized controlled trial. SETTING: Primary care physiotherapy units. SUBJECTS: A total of 84 patients diagnosed with non-specific mechanical neck pain. This sample was divided into two groups randomly: experimental (n = 42) versus control group (n = 42). INTERVENTIONS: Patients in both groups had a supervised therapeutic exercise programme, with the experimental group having additional interferential current stimulation treatment. MAIN MEASURES: The main measures used were intensity of neck pain according to the Visual Analogue Scale; the degree of disability according to the Neck Disability Index and the CORE Outcome Measure; anxiety and depression levels according to the Goldberg scale; apprehension as measured by the Personal Psychological Apprehension scale; and the range of motion of the cervical spine. The sample was evaluated at baseline and posttreatment (10 sessions/two weeks). RESULTS: Statistically significant differences between groups at posttreatment were observed for Visual Analogue Scale (2.73 ± 1.24 vs 4.99 ± 1.56), Neck Disability Index scores (10.60 ± 4.77 vs 18.45 ± 9.04), CORE Outcome Measure scores (19.18 ± 9.99 vs 35.12 ± 13.36), Goldberg total score (6.17 ± 4.27 vs 7.90 ± 4.87), Goldberg Anxiety subscale, Personal Psychological Apprehension Scale scores (28.17 ± 9.61 vs 26.29 ± 11.14) and active and passive right rotation. CONCLUSIONS: Adding interferential current stimulation to exercise resulted in better immediate outcome across a range of measures.
