Efficacy of low-level laser therapy on pain and disability in knee osteoarthritis: Systematic review and meta-analysis of randomised placebo-controlled trials
Stausholm, Martin Bjørn; Naterstad, Ingvill Fjell; Joensen, Jon; Lopes-Martins, Rodrigo Álvaro Brandão; Sæbø, Humaira; Lund, Hans; Fersum, Kjartan; Bjordal, Jan Magnus (Peer reviewed; Journal article, 2019)Objectives: Low-level laser therapy (LLLT) is not recommended in major knee osteoarthritis (KOA) treatment guidelines. We investigated whether a LLLT dose–response relationship exists in KOA. Design: Systematic review ... -
Efficacy of mobilisation with movement in chronic shoulder pain: protocol for a systematic review and meta-analysis of controlled trials
Storås, Arnstein; Lillebostad, Fabian Gudmundsen; Haslerud, Sturla Inge; Joensen, Jon; Bjordal, Jan Magnus; Stausholm, Martin Bjørn (Journal article; Peer reviewed, 2021)Introduction Shoulder pain affects approximately one in four adults and is thus one of the most common musculoskeletal problems. Only 50% of patients who begin treatment for shoulder pain are cured within 6 months. There ... -
