Upper Limb Motor Improvement after Traumatic Brain Injury: Systematic Review of Interventions

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Physical Therapy

Background:

• Traumatic brain injury (TBI) is a significant cause of adult disability, leading to cognitive and motor impairments.
• While balance and mobility are often prioritized, upper limb (UL) motor deficits require focused intervention.
• Understanding effective UL interventions post-TBI is crucial for comprehensive recovery.

Purpose of the Study:

• To systematically review and evaluate the effectiveness of interventions aimed at improving upper limb (UL) motor function following traumatic brain injury (TBI).
• To synthesize evidence on various therapeutic strategies for UL motor recovery in the TBI population.

Main Methods:

• A systematic literature search was conducted for studies published between 1990 and 2020.
• Study quality was assessed using the modified Downs and Black checklist, categorizing studies as excellent, good, fair, or poor.
• Effect sizes were calculated to quantify the effectiveness of different interventions.

Main Results:

• Twenty-three studies met the inclusion criteria, with most rated as fair or good quality.
• Interventions included therapies for muscle tone, constraint-induced movement therapy, virtual reality, non-invasive stimulation, and task-oriented training.
• Most interventions demonstrated medium to large effect sizes for improving motor impairment and activity limitations, though retention testing was limited.

Conclusions:

• Preliminary evidence suggests that several interventions can enhance UL motor function after TBI.
• Further research is needed to identify the most effective interventions and optimize their application for TBI patients.
• Targeted UL interventions are vital for improving functional outcomes and quality of life in individuals with TBI.
