Results From a Randomized Controlled Trial to Address Balance Deficits After Traumatic Brain Injury.

OBJECTIVE: To evaluate the efficacy of an in-home 12-week physical therapy (PT) intervention that utilized a virtual reality (VR) gaming system to improve balance in individuals with traumatic brain injury (TBI). SETTING: Home-based exercise program (HEP). PARTICIPANTS: Individuals (N=63; traditional HEP n=32; VR n=31) at least 1 year post-TBI, ambulating independently within the home, not currently receiving PT services. MAIN OUTCOME MEASURES: Primary: Community Balance and Mobility Scale (CB&M); Secondary: Balance Evaluation Systems Test (BESTest), Activities-Specific Balance Confidence Scale (ABC), Participation Assessment with Recombined Tools-Objective (PART-O). RESULTS: No significant between-group differences were observed in the CB&M over the study duration (P=.9983) for individuals who received VR compared to those who received a HEP to address balance deficits after chronic TBI nor in any of the secondary outcomes: BESTest (P=.8822); ABC (P=.4343) and PART-O (P=.8822). However, both groups demonstrated significant improvements in CB&M and BESTest from baseline to 6, 12, and at 12 weeks follow-up (all P's <.001). Regardless of treatment group, 52% of participants met or exceeded the minimal detectable change of 8 points on the CB&M at 24 weeks and 38% met or exceeded the minimal detectable change of 7.81 points on the BESTest. CONCLUSION: This study did not find that VR training was more beneficial than a traditional HEP for improving balance. However, individuals with chronic TBI in both treatment groups demonstrated improvements in balance in response to these interventions which were completed independently in the home environment.

Balance in chronic traumatic brain injury: correlations between clinical measures and a self-report measure.

OBJECTIVE: To assess associations among commonly used self-report and clinical measures of balance in chronic TBI. DESIGN: Cross-sectional analysis of balance in a convenience sample of individuals at least one year post TBI. MAIN OUTCOME MEASURES: Activities-Specific Balance Confidence Scale (ABC) (self-reported balance impairment), Community Balance and Mobility Scale (CB&M) (clinical measure validated in TBI), and Balance Evaluation Systems Test (BESTest) (clinical measure not validated in TBI). METHODS: Fifty-nine individuals (64% male, mean age 48.2 years) ambulating independently within the home participated in testing. Pearson correlation coefficients were used to quantify the direction and magnitude of the relationships among the three balance impairment measures. RESULTS: A significant positive correlation was noted between the ABC and CB&M (r = 0.42, p = 0.0008), between the ABC and BESTest (r = 0.46, p = 0.0002), and between the CB&M and BESTest (r = 0.86, p < 0.0001). CONCLUSIONS: This is the first study we are aware of in the chronic moderate to severe TBI population directly comparing patient's self-reported balance impairment with clinical measures. Positive correlations were found between the self-report measure and both clinical measures. Overall, individuals with chronic TBI tend to self-report less impaired balance than clinical measures indicate. These results provide preliminary evidence to support the need for validation of the BESTest in this population. ABBREVIATIONS: ABC: Activities-specific balance confidence scale; BESTest: balance evaluation systems test; BOS: base of support; COM: center of mass; CB&M: community balance and mobility scale; CI: confidence interval; IQR: interquartile range; PTs: physical therapists; SD: standard deviation; SE: standard error; TBI: traumatic brain injury.

Patterns in Wheeled Mobility Skills Training, Equipment Evaluation, and Utilization: Findings from the SCIRehab Project.

Patients with traumatic spinal cord injury (SCI) participate in manual and power wheelchair (WC) skills training during inpatient rehabilitation; wheeled mobility evaluations aim to optimize use, fit, and function of equipment following discharge. Occupational and physical therapists documented treatment sessions during inpatient rehabilitation to describe types and quantity of WC skills training and adaptive equipment (AE) provided by neurological level of injury. Most patients participated in WC skills training; variation in type and frequency exists. Propulsion/driving skills were practiced most frequently. A majority of patients participated in equipment evaluations; assessment/prescription and fitting were performed frequently; mat evaluations were done infrequently. Most patients received mobility equipment in a timely manner; they continued to use their WC and were satisfied with its fit and function at the one-year injury anniversary. High levels of respondent satisfaction with fit and function of WCs suggest clinicians are prescribing mobility devices adequately and accurately supplementing information obtained during equipment assessment and fitting sessions with information from general treatment sessions. Variation in type and frequency of WC training provided by level of SCI and in types of WC prescribed use provides a foundation for future research to relate treatment modalities with functional and participation outcomes.

Virtual reality-based therapy for the treatment of balance deficits in patients receiving inpatient rehabilitation for traumatic brain injury.

OBJECTIVE: To evaluate the feasibility and safety of utilizing a commercially available virtual reality gaming system as a treatment intervention for balance training. DESIGN: A randomized controlled trial in which assessment and analysis were blinded. SETTING: An inpatient rehabilitation facility. INTERVENTION: Interventions included balance-based physical therapy using a Nintendo Wii, as monitored by a physical therapist, and receipt of one-on-one balance-based physical therapy using standard physical therapy modalities available for use in the therapy gym. RESULTS: Participants in the standard physical therapy group were found to have slightly higher enjoyment at mid-intervention, while those receiving the virtual reality-based balance intervention were found to have higher enjoyment at study completion. Both groups demonstrated improved static and dynamic balance over the course of the study, with no significant differences between groups. Correlational analyses suggest a relationship exists between Wii balance board game scores and BBS scores for measures taken beyond the baseline assessment. CONCLUSIONS: This study provides a modest level of evidence to support using commercially available VR gaming systems for the treatment of balance deficits in patients with a primary diagnosis of TBI receiving inpatient rehabilitation. Additional research of these types of interventions for the treatment of balance deficits is warranted.

Relationship of physical therapy inpatient rehabilitation interventions and patient characteristics to outcomes following spinal cord injury: the SCIRehab project.

BACKGROUND/OBJECTIVE: Examine associations of type and quantity of physical therapy (PT) interventions delivered during inpatient spinal cord injury (SCI) rehabilitation and patient characteristics with outcomes at the time of discharge and at 1 year post-injury. METHODS: Physical therapists delivering routine care documented details of PT interventions provided. Regression modeling was used to predict outcomes at discharge and 1 year post-injury for a 75% subset; models were validated with the remaining 25%. Injury subgroups also were examined: motor complete low tetraplegia, motor complete paraplegia, and American Spinal Injury Association (ASIA) Impairment Scale (AIS) D motor incomplete tetra-/paraplegia. RESULTS: PT treatment variables explain more variation in three functionally homogeneous subgroups than in the total sample. Among patients with motor complete low tetraplegia, higher scores for the transfer component of the discharge motor Functional Independence Measure () are strongly associated with more time spent working on manual wheelchair skills. Being male is the most predictive variable for the motor FIM score at discharge for patients with motor complete paraplegia. Admission ASIA lower extremity motor score (LEMS) and change in LEMS were the factors most predictive for having the primary locomotion mode of "walk" or "both (walk and wheelchair)" on the discharge motor FIM for patients with AIS D injuries. CONCLUSION: Injury classification influences type and quantity of PT interventions during inpatient SCI rehabilitation and is a strong predictor of outcomes at discharge and 1 year post-injury. The impact of PT treatment increases when patient groupings become more homogeneous and outcomes become specific to the groupings. Note: This is the second of nine articles in the SCIRehab series.

Group physical therapy during inpatient rehabilitation for acute spinal cord injury: findings from the SCIRehab Study.

BACKGROUND: Inpatient rehabilitation for spinal cord injury (SCI) includes the use of both individual and group physical therapy sessions. A greater understanding of group physical therapy use will help in the evaluation of the appropriateness of its use and contribute to the development of standards of practice. OBJECTIVE: This report describes the extent to which group physical therapy is being used in inpatient rehabilitation for SCI, identifies group physical therapy interventions being delivered, and examines patterns in the types of activities being used for people with different levels and completeness of injury (ie, injury groups). DESIGN: The SCIRehab Study is a 5-year, multicenter investigation that uses practice-based evidence research methodology. METHODS: Data on characteristics of participants and treatments provided were collected through detailed chart review and customized research documentation completed by clinicians at the point of care. The analyses described here included data from 600 participants enrolled during the first year of the project. RESULTS: Most of the participants (549/600) spent time in group physical therapy, and 23% of all documented physical therapy time was spent in group sessions. The most common group physical therapy activities were strengthening, manual wheelchair mobility, gait training, endurance activities, and range of motion/stretching. Time spent in group physical therapy and the nature of activities performed varied among the injury groups. LIMITATIONS: Physical therapy use patterns observed in the 6 participating centers may not represent all facilities providing inpatient rehabilitation for SCI. Research documentation did not include all factors that may affect group physical therapy use, and some sessions were not documented. CONCLUSIONS: The majority of physical therapy was provided in individual sessions, but group physical therapy contributed significantly to total physical therapy time. Group physical therapy time and activities differed among the injury groups in patterns consistent with clinical goals.

The SCIRehab project: treatment time spent in SCI rehabilitation. Physical therapy treatment time during inpatient spinal cord injury rehabilitation.

BACKGROUND/OBJECTIVE: To describe the nature and distribution of activities during physical therapy (PT) delivered in inpatient spinal cord injury (SCI) rehabilitation and discuss predictors (patient and injury characteristics) of the amount of time spent in PT for specific treatment activities. METHODS: Six hundred patients from six inpatient SCI centers were enrolled in the SCIRehab study. Physical therapists documented details, including time spent, of treatment provided during 37 306 PT sessions that occurred during inpatient SCI rehabilitation. Ordinary least squares regression models associated patient and injury characteristics with time spent in specific PT activities. RESULTS: SCIRehab patients received a mean total of 55.3 hours of PT over the course of their rehabilitation stay. Significant differences among four neurologic groups were seen in the amount of time spent on most activities, including the most common PT activities of strengthening exercises, stretching, transfer training, wheelchair mobility training, and gait training. Most PT work (77%) was provided in individual therapy sessions; the remaining 23% was done in group settings. Patient and injury characteristics explained only some of the variations seen in time spent on wheelchair mobility, transfer and bed mobility training, and range of motion/ stretching. CONCLUSION: Analysis yielded both expected and unexpected trends in SCI rehabilitation. Significant variation was seen in time spent on PT activities within and among injury groups. Providing therapeutic strengthening treatments consumed the greatest proportion of PT time. About one-quarter of all PT services were provided in group settings. Details about services provided, including time spent, will serve as a starting point in detailing the optimal treatment delivery for maximal outcomes.

SCIRehab Project series: the physical therapy taxonomy.

BACKGROUND/OBJECTIVE: Outcomes research is in need of a classification system of physical therapy (PT) interventions for acute traumatic spinal cord injury (SCI) rehabilitation in the United States. The objective of this study was to describe a taxonomy (system to categorize and classify interventions) to examine the effects of PT interventions on rehabilitation outcomes. METHODS: The SCIRehab study uses the rigorous observational practice-based evidence methodology to examine current treatment processes without changing existing practice. PT clinicians and researchers from 6 centers developed a taxonomy to describe details of each PT session. RESULTS: The PT taxonomy consists of 19 treatment activities (eg, bed mobility, transfers, wheelchair mobility, strengthening and stretching exercises) and supplementary information to describe the associated therapeutic interventions. Details that focus on patient assistance needs and family involvement are included as additional descriptors to help to describe and justify PT activity selection. Time spent on each activity is used as the measure of intensity. CONCLUSION: The detailed PT taxonomy documentation process, which offers efficiency in data collection, is being used for all PT sessions with 1,500 patients with acute traumatic SCI at the 6 participating centers. It might be the first attempt to document the many details of the PT rehabilitation process for patients with SCI in the United States.
