Interferential current and photobiomodulation in knee osteoarthritis: A randomized, placebo-controlled, double-blind clinical trial.

Objectives: To evaluate the effects of interferential current and photobiomodulation in patients with knee osteoarthritis.

Design: A randomized, placebo-controlled, double-blind clinical trial.

Setting: Physiotherapy Clinic of City University of São Paulo.

Low-level laser therapy and interferential current in patients with knee osteoarthritis: a randomized controlled trial protocol.

The aim of this study is to investigate the effects of low-level laser therapy and interferential current (IFC) on pain intensity, central sensitization, muscle strength and functional capacity in patients with knee osteoarthritis. Participants will be patients aged between 50 and 80 years, with knee osteoarthritis, pain intensity ranging from 3 to 8 points (0-10 scale), Lequesne Algofunctional Index ranging from 5 to 15 points, and Kellgren & Lawrence grade ≥2. A total of 168 patients will be randomly allocated into four groups as follows: active IFC + laser sham (G1), IFC sham + active laser (G2), active IFC + laser (G3) and IFC + laser sham (G4).

Effectiveness of back school versus McKenzie exercises in patients with chronic nonspecific low back pain: a randomized controlled trial.

Background: Back School and McKenzie methods are popular active treatment approaches that include both exercises and information for patients with chronic nonspecific low back pain.

Objective: The purpose of this study was to compare the effectiveness of Back School and McKenzie methods in patients with chronic nonspecific low back pain.

Design: The study was a prospectively registered, 2-arm randomized controlled trial with a blinded assessor.

Improvement in pain, fatigue, and subjective sleep quality through sleep hygiene tips in patients with fibromyalgia.

Objective: To evaluate the effectiveness of sleep hygiene instructions for women with fibromyalgia.

Materials And Methods: Seventy women with fibromyalgia completed the study. The assessment comprised the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI), and a general questionnaire with personal data and lifestyle information.

Isokinetic assessment of the hip muscles in patients with osteoarthritis of the knee.

Objectives: To evaluate the difference in isokinetic strength of hip muscles between patients with knee osteoarthritis (OA) and matched healthy controls, and to establish the correlation between this isokinetic strength and pain and function in patients with knee OA.

Methods: 25 patients with a diagnosis of unilateral knee OA, 25 patients with bilateral knee OA, and 50 matched controls were evaluated using the visual analog scale for pain, knee Lequesne index, Western Ontario and McMaster Universities questionnaire and an isokinetic test.

Results: The groups were matched for age, gender and body mass index.
