Conclusion

Maniar et al. (2012)

7 Randomized controlled trial

84 Control: conventional physical therapy Experimental 1: conventional physical therapy and 2 CPM applications of 15 minutes on day 2 after TKA Experimental 2: conventional physical therapy and 2 CPM applications of 15 minutes each for 3 days

Pain on VAS, AROM, TUG score, swelling, WOMAC, wound healing

There was no significant beneficial role of CPM in the immediate functional recovery after TKA.

Denis et al. (2006)

7 Randomized clinical trial

81 Control: conventional physical therapy only Experimental 1: conventional physical therapy and 35 minutes of CPM applications daily Experimental 2: conventional physical therapy and 2 hours of CPM applications daily

Active knee flexion AROM at discharge

Active knee extension AROM, TUG score, WOMAC score, length of stay

There were no significant differences in outcome measures found amongst the three groups in primary or secondary outcome measures.

Herbold et al. (2014)

6 Randomized controlled trial

141 Control: conventional therapy 3 hours/day Experimental: conventional therapy and daily CPM application for 2 hours/day

Discharge knee flexion AROM

Knee extension AROM, total FIM score, TUG score, girth, WOMAC score

The study demonstrated no significant benefit of CPM use during post-acute rehabilitation phase compared to conventional

care. Boese et al. (2014)

6 Randomized controlled trial

160 Control: no CPM Experimental 1: CPM device on and moving from immediate post-operative period Experimental 2: CPM device on and stationary at 90 degrees flexion for the first night and moving throughout rest of stay

Change in hemoglobin level, AROM, girth

Cost data The use of CPM provided no apparent benefit to patients recovering from TKA in all outcome variables. Hospital costs can be reduced without the use of CPMS.

Herbold et al. (2012)

5 Matched cohort study

122 Control: no CPM Experimental: Use of CPM for 2 hours/day as an adjunct to conventional 3 hours of therapy in an inpatient rehabilitation facility

Discharge active knee flexion AROM and flexion gain

FIM scores, discharge ambulation device, destination after discharge, need for home care services after inpatient stay

There was no significant difference found in the outcome measures, as the results do not support the use of CPM in an inpatient rehabilitation facility as an adjunct to physical therapy.
