The Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) is not available to Portuguese-Brazil. This study translates, cross-culturally adapts, and validates the PASIPD for Brazilian individuals with Parkinson’s disease. The translation process followed guidelines: initial translation, synthesis, back translation, expert committee, and pretest. The validation and reliability processes were conducted with 40 individuals (15 men and 25 women) with Parkinson’s disease. Concurrent validity was evaluated between PASIPD to Brazilian Portuguese, International Physical Activity Questionnaire, and Human Activity Profile. PASIPD to Brazilian Portuguese was found to be moderately correlated with International Physical Activity Questionnaire (r = .474, p < .05); however, there was no correlation with Human Activity Profile (r = .271, p < .05). We used the intrarater reliability with intraclass correlation coefficient and test–retest. Intrarater reliability was high (intraclass correlation coefficient = .80). Internal consistency was considered adequate by Cronbach’s alpha (α = .70). PASIPD to Brazilian Portuguese is a valid and reliable instrument for evaluating physical activity levels in Brazilian individuals with Parkinson’s disease.

葡萄牙语-巴西无法使用身体残障人士的身体活动量表 (PASIPD)。本研究针对巴西帕金森病患者翻译、跨文化改编和验证 PASIPD。翻译过程遵循以下准则：初译、综合、回译、专家委员会和预测试。验证和可靠性过程是针对 40 名帕金森病患者（15 名男性和 25 名女性）进行的。评估了 PASIPD 与巴西葡萄牙语、国际身体活动问卷和人类活动概况之间的同时有效性。巴西葡萄牙语的 PASIPD 被发现与国际体育活动问卷调查有适度的相关性 ( r  = .474, p < .05); 然而，与人类活动概况没有相关性 ( r  = .271, p  < .05)。我们使用具有组内相关系数和重测的评分者内部信度。评分者内部可靠性高（组内相关系数 = .80）。Cronbach 的 alpha (α = .70) 认为内部一致性足够。巴西葡萄牙语的 PASIPD 是评估巴西帕金森病患者身体活动水平的有效且可靠的工具。
