|Population: Mean age=38yr; Gender: males=12, females=3; Level of injury: paraplegia=13, quadriplegia=2; Mean time post injury=16yr; Type of pain: musculoskeletal.
Intervention: Individuals using wheelchairs were randomized to an exercise program alone (control, n=7) or with EMG biofeedback (treatment, n=8). Exercise programs were taught in two 90min sessions and were to be performed at home (1x/d, 5d/wk, 10wk). EMG biofeedback training was provided in 4 sessions (90min). Outcomes were assessed at baseline, 10wk, and 6mo.
Outcome Measures: Wheelchair User Shoulder Pain Index (WUSPI).
|1. The treatment group had a significant reduction in WUSPI score at 10wk (Δ=64%, p=0.02) while the control group did not (Δ=27%, p=0.42).
2. There were significant reductions in WUSPI score at 6mo in both the control group (Δ=63%, p=0.03) and treatment group (Δ=82%, p=0.004).
|Ginis et al. 2003
|Population: SCI: Mean age=38.6 yr; Gender: males=23, females=11; Severity of injury: complete=14, incomplete=13. Type of pain=neuropathic and musculoskeletal.
Intervention: Participants in the non-exercise group were asked to continue their usual activities but they were asked not to exercise regularly. Those in the exercise group participated in 5 min of stretching, 15-30 min of aerobic arm ergometry exercise and 45-60 min of resistance exercise. These subjects trained 2x/wk in small groups.
Outcome Measures: Pain perception (two items from the Short form-36 Health Survey), symptom self-efficacy and perceived control (two core items from the Beliefs scale and a modified version of the arthritis belief scale), stress was measured using the perceived stress scale.
|1. After 3 mo, changes in potential mediators were seen in:
· The treatment group showed a significant decrease in stress (p=0.01) and pain (p=0.03) than the control group.
· The two groups for QoL (p=0.007); satisfaction with physical function (p<0.01); satisfaction with physical appearance (p=0.007); depression (p=0.02).
2. Stress and pain (mediators of QoL):
· Once baseline pain and stress were controlled for, the 3 mo scores for pain was (R2=.15, p<0.01) and for stress it was (R2=0.12,p<0.01).
· These were significant predictors of baseline adjusted 3 mo QoL.
3. Stress and pain as mediators of depression:
· Changes in pain but not stress explained significant variance in baseline adjusted depression scores (R2=0.19 and 0.04).
· Adjusted pain scores showed variance in the adjusted 3 mo depression scores (R2=0.19 and <0.01).
|Curtis et al. 1999
|Population: Mean age=35 yr; Gender: males=35, females=7; Level of injury=cervical to lumbar; Duration of wheelchair use=24 yr. Type of pain=nociceptive.
Intervention: The experimental group attended a 60 min educational session where they were instructed in five shoulder exercises.
Outcome Measures: Self-report questionnaire (demographic and medical info), Wheelchair User’s Shoulder Pain Index (WUSPI), and Visual Analogue Scale (VAS) used to rate intensity of pain.
|1. When looking at the effect of exercise intervention on performance corrected (PC) WUSPI, a two factor repeated measures ANOVA showed a significant effect of time only (p=0.048).
2. There were no significant differences between control and experimental group in age, years of wheelchair use or activity levels although the control group had much lower pain scores at baseline.

3. At wk 20, one patient reported increased pain from unrelated factor.
4. During the 4 wk retention phase, the WUSPI scores indicated a trend toward increasing shoulder pain. However, no significant increase was found compared to the last week of using the MAGICWheels (p<0.05).
5. During the MAGICWheels phase, patients encounter significantly more carpeted (p<0.01) and grass (p<0.001) surfaces in comparison to the baseline phase.
6. During the retention phase patients encountered significantly more hills (p=0.009) and gravel (p=0.03) surfaces in comparison to the baseline phase.
