Dose Escalation Upper Limb Rehabilitation in Stroke

Finding the Optimal Session Length of Upper Limb Rehabilitation of People With Moderate to Severe Upper Limb Sensorimotor Impairments After Acute Stroke: A Dose Escalation Study

A phase 1, single-ascending dose clinical trial will be conducted. This study will be designed to test increasing doses of multimodal exercise in successive cohorts of six participants (cumulative 3 + 3 design)[22] (Figure 1). Maximum dose is reached when two or more participants experience DLT. DLT, dose-limiting tolerance. The 'dose' will be defined as the ability to reach a fixed maximal level of exercise (type, duration (including session length) in the first two weeks post-stroke without experiencing dose-limiting tolerance (DLT). DLT thresholds will be based on failure to complete more than 20% of prescribed 3-day rehabilitation dose due to pain, rate of perceived exertion, fatigue, or effort required. Rehabilitation and measurement sessions will be held at either at the Stroke or Geriatric Units at Campus Sint-Jan, Genk or at the rehabilitation unit at Sint-Barbara, Lanaken, with medical services on site. All participants will be monitored for fatigue and pain pre, during and at post-intervention daily. The researchers (PI of project [Dr Peter Hallet, ZOL] Postdoctoral Researcher [Dr Lisa Tedesco Triccas, UHasselt] and PhD/Masters Students [UHasselt) will conduct the clinical tests and will conduct the rehabilitation program.

a stroke-specific, performance-based impairment index.The scale is comprised of five domains and there are 155 items in total (motor functioning, sensory functioning, balance, joint range motion, joint pain). Scoring is based on direct observation of performance. Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale where 0=cannot perform, 1=performs partially and 2=performs fully. The total possible scale score is 226.

The scale consists of 18 items relating to the subjective experience of fatigue.Each line is 100 mm in length - thus, scores fall between 0 and 100. The instrument also possesses two subscales: fatigue (items 1-5 and 11-18) and energy (items 6-10).
