[Is exercise therapy and manipulation effective in low back pain?].

Area of Science:

• Orthopedics
• Physical Therapy
• Evidence-Based Medicine

Background:

• Low back pain is a common, often self-limiting condition.
• Current guidelines sometimes recommend manipulation for acute low back pain.

Purpose of the Study:

• To systematically review the effectiveness of exercises and manipulation for low back pain.
• To evaluate impacts on pain, disability, and sick leave across different pain durations.

Main Methods:

• Systematic review of randomized controlled trials.
• Analysis of 11 studies covering acute (0-4 weeks), subacute (4-12 weeks), and chronic (>12 weeks) low back pain.

Main Results:

• No additional benefits from exercises or manipulation for acute low back pain.
• Evidence suggests graded exercise programs can reduce disability and sick leave in subacute and chronic stages.
• Manipulation showed no superior effectiveness compared to other treatments or placebo.
• Exercise effectiveness on sick leave for chronic pain is not documented.

Conclusions:

• Guidelines recommending manipulation for acute low back pain are not supported by current evidence.
• Exercises, particularly graded programs, are effective for managing disability and pain in subacute and chronic low back pain.
• Further research is needed to clarify the impact of exercises on sick leave for chronic low back pain.
