McAvinue and Robertson (2011)65 case series (n = 4) | PLP (AKA, BKA 1.7 to 19 yrs previously) on 40-yr-old man, 45-yr-old man, 66-yr-old man, and 25-yr-old woman | Four weekly sessions of movement imagery training followed by 6 wks training on increasing the awareness of the phantom and in movement of the stump and imagined movement of the phantom; daily practice and pain diaries | All participants improved in imagery after training, although two more than the others. Through interrupted time series analysis, one of the four participants noted an improvement in PLP. | n/a |
Zuckweiler (2005)64 uncontrolled trial (n = 14) | PLP (leg, hand, finger 1–21 yrs previously); 71% male, aged 30–80 yrs | 5 to 15 imagery sessions using ZIPS over 4–20 wks; ZIPS encourages precise body image and improved mind-body sensory messaging. | Significant reduction in PLP frequency at end of intervention and at 6 mos (7-point scale, χ2) | <0.001 |
Maclver et al. (2008)33 uncontrolled trial (n = 13) | PLP for 3–51 yrs (arm); 11 men, 3 women | Six training sessions: guided body scan for relaxation followed by sensory and motor imagery training; participants were encouraged to practice daily with a 40-min CD and do a 10-min exercise to use without a CD. | Significant decrease in pain intensity (NRS, 7.5 of 10 to 4.0 of 10) and exacerbations (6.0 to 3.0); training resulted in reduced motor and sensory cortical reorganization (inappropriate activation of contralateral hand/arm cortical area) by fMRI | <0.001 |
Beaumont et al. (2011)66 uncontrolled trial (n = 6) | PLP for 0.6–28 yrs (arm, AKA, BKA); all men, aged 32–65 yrs | Participants chose 10 of 48 movements from a video to practice with the phantom. Training (30 mins, twice weekly) over 4 wks added two movements per week to the initial 4. At home, participants practiced 30 mins with a video for an additional 4 wks. | Imagery ability improved in all but one. Four participants noted at least 30% reduction in pain after the intervention, but only one noted persistence of the improvement at 6 mos (without practice). Psychologic health appeared to be a factor in degree of improvement. | n/a |
AKA, above-the knee (transfemoral) amputation; BKA, below-the-knee (transtibial) amputation; fMRI, functional magnetic resonance imaging; NRS, numeric rating scale; PLP, phantom limb pain; n/a, not applicable; ZIPS, Zuckweiler’s Image Imprinting.
