The health crisis caused by COVID-19 has had a huge impact on the provision of physiotherapists’ services during the pandemic. Patellofemoral pain syndrome (PFPS) is a major health problem and one of the most common causes of pain in the front of the knee in outpatients. The objective was to evaluate the effectiveness of a therapeutic physical exercise (TPE) program supervised by a physiotherapist using telematic channels in reducing pain and disability in a sample of 54 patients with PFPS in the Physiotherapy Service of the San José de la Rinconada Health Center (Seville). Subjects were evaluated pre- and post-intervention (4 weeks—12 treatment sessions). An analysis was made of perceived pain—using the visual analog scale (VAS) and the DN4 neuropathic pain questionnaire—and functional balance—through the Kujala Score test and the Lower Extremity Functional Scale. The supervised TPE program in patients with PFPS produced a reduction in pain: VAS F_{1, 52} = 8.68 (p = 0.005) η² = 0.14 and DN4: F_{1, 52} = 69.94 (p = 0.000) η² = 0.57; and in Lower Extremity Functional Scale (LEFS) disability: F_{1, 52} = 19.1 (p = 0.000) η² = 0.27 and KUJALA: F_{1, 52} = 60.28 (p = 0.000) η² = 0.54, which was statistically significant (p = 0.000 for p < 0.05). Hence, the TPE program presented was effective in reducing pain and disability in patients with PFPS.

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.

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: F_1,26 = 92.43, p < 0.000, ŋ² = 0.78 and DN4: F_1.26 = 124.15, p < 0.000, ŋ² = 0.82), as well as improvements in functionality (LEFS: F_1.26 = 72.42, p < 0.000, ŋ² = 0.74 and Kujala: F_1.26 = 40.37, p < 0.000, ŋ² = 0.61]) and in ROM (Flexion: F_1.26 = 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.

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.

Background: Therapeutic exercise is recommended for people with knee osteoarthritis (OA), although it could be complemented with other treatments such as dry needling (DN). The purpose of this study was to evaluate and compare the resulting data on pain, functionality, strength and range of motion in subjects with knee osteoarthritis after being treated with a specific therapeutic physical exercise program alone or in combination with the DN technique in the popliteus muscle. Methods: A total of 33 participants were randomly assigned to two groups: the dry needling plus therapeutic physical exercise group (n = 15) and the therapeutic physical exercise alone group (n = 18). Both groups received the same exercise protocol, and the dry-needling group conducted three sessions of this technique over 3 weeks. Results: Variables such as pain, functionality, neuropathic pain, stiffness, strength, range of motion, pain catastrophizing and kinesiophobia were evaluated before and after the intervention, as well as at a follow-up 3 months after the intervention. Significant differences were observed between the two groups in pain intensity, stiffness, functionality, pain catastrophizing and kinesiophobia (p < 0.001). Conclusions: The combination of dry needling targeting the popliteus muscle and therapeutic physical exercise showed better results in terms of pain, functionality and strength compared to therapeutic physical exercise alone, especially after the intervention.

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.
