A Systematic Review of Isokinetic Muscle Strength in a Healthy Population With Special Reference to Age and Gender.

Context: Despite increasing use of reference values in isokinetic measurements and increasing importance, there is no systematic review of the reference values for lower and upper limb isokinetic muscle strength.

Objective: A systematic review to analyze studies on the reference values and protocols for the measurement for upper and lower limb isokinetic muscle strength in an untrained and noninjured healthy population.

Data Sources: MEDLINE, Scopus, Scielo, and CINAHL (from the earliest date available to June 2020).

Does adding hip strengthening exercises to manual therapy and segmental stabilization improve outcomes in patients with nonspecific low back pain? A randomized controlled trial.

Background: The literature is unclear on the need for hip strengthening in persons with low back pain (LBP).

Objectives: To investigate the effectiveness of hip strengthening exercises when added to manual therapy and lumbar segmental stabilization in patients with chronic nonspecific LBP.

Methods: Seventy patients with chronic nonspecific LBP were randomly assigned to either the manual therapy and lumbar segmental stabilization group or the manual therapy and lumbar segmental stabilization plus specific hip strengthening group.

Addition of specific hip strengthening exercises to conventional rehabilitation therapy for low back pain: a systematic review and meta-analysis.

Objective: To examine the effectiveness of hip strengthening exercises in reducing pain and disability in persons with low back pain.

Methods: We searched for randomized controlled clinical trials on MEDLINE, the Physiotherapy Evidence Database, the Cochrane Central Register of Controlled Trials, LILACS, Scielo and CINAHL from the earliest date available to June 2020. Studies that included hip strengthening exercises for persons with low back pain and included pain and/or disability as an outcome measure were evaluated by two independent reviewers.

Lower limb muscle strength in patients with low back pain: a systematic review and meta-analysis.

Objective: To systematically review the published studies that compare lower limb muscle strength in patients with low back pain to matched healthy controls.

Methods: We searched Medline, SciELO, Cumulative Index to Nursing and Allied Health (CINAHL), and Scopus up until December 2017. Studies comparing lower limb muscle strength in people diagnosed with low back pain to healthy control participants were included in the systematic review.

Effects of the FIFA 11 training program on injury prevention and performance in football players: a systematic review and meta-analysis.

Objective: To investigate the effects of FIFA 11 training on injury prevention and performance in football players.

Design And Methods: Systematic review and meta-analysis. We conducted a systematic search using four databases (CINAHL, Cochrane Library, EMBASE, and PubMed) to find controlled trials evaluating the effects of FIFA 11 on injury prevention and performance among football players.
