1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

purposeThis study investigates the effectiveness of preoperative high-intensity strength training (with a special emphasis on lower limb muscle strength and secondarily on balance training) on postural control after TKA.

methodsForty-four subjects (7 men, 37 women, and mean age 66.7 ± 3.9 years) scheduled for unilateral TKA for osteoarthritis (OA) participated in this randomized-controlled trial. Each patient performed two postural control tests: Romberg test with eyes open and closed. These tests were assessed at 8 weeks before surgery (T1), after 8 weeks of training (T2), 1 month after TKA (T3), and finally 3 months after TKA (T4). The intervention group completed an 8-week training program 3 days per week prior to surgery, while the control group received no intervention.

resultsThe Center of Pressure area (COP) was lower (i.e., better score) for the intervention group at T2, T3, and T4. The anteroposterior range of COP with eyes open was lower in the intervention group at T2, T3, and T4 and with eyes closed at T2. The medial-lateral standard deviation of COP with eyes open was lower in the intervention group at T2 and T4 and with eyes closed at T2 and T3. The anteroposterior standard deviation of COP with eyes open did not change, while that with eyes closed the intervention group showed lower score at T2.

conclusionPreoperative high-intensity strength training is effective for improving postural control before and early after TKA. Recommendations should include preoperative strength training, and not only balance training, to speed-up recovery of postural control after TKA. LEVEL OF EVIDENCE: 1.
