Population: Age = 25-40 yrs; Gender: males = 6, females = 2; Level of injury paraplegia; Time since injury = 12-20 yrs.
Treatment: Study 1 - Behavioural Intervention: 3 primary components-health plan, clinic visits and financial rewards. Study 2 - Behavioural intervention: 2 treatments components were implemented (Health plan and visits) during the initial phase.  Phase 2 - which began after the patient began to experience skin problems (Included visits plus payment).
Outcome Measures: Severity of pressure sores were recorded at each level; Ulcer severity - classified using PUSH tool.

Study 1:

1. Average Pressure Ulcer Scale for Healing (PUSH) decreased from baseline by an average of 10.5 points per participant. 
2. 6 participants were hospitalized (not during the intervention) a total of 16 times during baseline for treatment of pressure ulcers. 
3. Fewer hospitalizations were also noted during the post-intervention phase compared to the baseline phase.  Average monthly cost of care decreased from $6262.00/participant to $235.00 (US)

Study 2:

1. Mean PUSH scores decreased from baseline by 8.3 points (visits only) and a further 3.1 points (visits & payment phase).
2. Total number of hospitalizations decreased from 1.67 (baseline) to 0.33 (intervention and post-intervention phase).
